Best Shopify Integrations for Accounting: QuickBooks, Xero, Amazon and Wholesale
For most Shopify stores the best accounting software is QuickBooks Online or Xero, fed by a payout-level connector: A2X or Link My Books for Shopify plus Amazon, Synder for many payment gateways, Webgility for deep QuickBooks automation, or Intuit's free connector for a small single-channel store. This guide compares them, covers stock sync (Cin7, Katana, Trunk) and shows how a brand selling on Shopify, Amazon and wholesale at once gets everything into one set of books.

Key Takeaway
For most Shopify stores the best accounting software is QuickBooks Online or Xero, fed by a payout-level connector: A2X or Link My Books for Shopify plus Amazon, Synder for many payment gateways, Webgility for deep QuickBooks automation, or Intuit's free connector for a small single-channel store. This guide compares them, covers stock sync (Cin7, Katana, Trunk) and shows how a brand selling on Shopify, Amazon and wholesale at once gets everything into one set of books.
Why Shopify Merchants Need Integrations
If you are running a Shopify store with more than a handful of orders per day, you already know the pain of manual bookkeeping. Every order generates revenue, shipping charges, discounts, tax collected, payment gateway fees, and (frequently) refunds. Multiply that by 50, 200, or 1,000 orders per day and the data entry becomes a full-time job -- one that adds zero strategic value to your business.
Manual processes break in predictable ways:
- Accuracy collapses at scale. One miskeyed digit in a spreadsheet cascades into incorrect VAT filings, wrong profit margins, and stock discrepancies that take hours to trace.
- Reconciliation becomes a nightmare. Shopify batches dozens of orders into a single bank payout. Without an integration that breaks the payout down into its components (gross sales, fees, refunds, net deposit), matching your bank feed to your books is guesswork.
- Inventory drift. If your accounting system does not reflect real-time stock levels and COGS, you are making purchasing and pricing decisions based on stale data.
- Time cost. Merchants report spending 5--15 hours per week on manual bookkeeping tasks that an integration eliminates entirely.
Shopify integrations fall into three broad categories, and most growing stores need at least one from each:
- Accounting integrations -- sync sales, fees, refunds, and tax to your accounting platform (QuickBooks, Xero, Sage)
- Inventory integrations -- track stock levels, COGS, and manufacturing across warehouses and sales channels
- Payment integrations -- reconcile multi-gateway payouts (Stripe, PayPal, Shopify Payments) with your general ledger
This guide covers the best tools in each category, with honest pricing, feature comparisons, and recommendations based on your store's size and complexity. No affiliate links, no sponsorships -- just an independent breakdown of Shopify integrations that actually work. If you sell on Amazon or wholesale as well as Shopify, start with the next section, which is written for exactly that setup.
Selling on Shopify, Amazon and Wholesale? How to Get It All into QuickBooks or Xero
Most of the people who land on this page are not running a single Shopify store. They are product brands selling on Shopify and Amazon, with a wholesale side that invoices retailers directly, and they want one question answered: how do we get sales, fees, payouts, stock and wholesale invoices into QuickBooks or Xero without someone retyping it all?
The short answer is that no single app does the whole job. A working setup has three parts, and each part has a clear best tool:
- Sales, fees and payouts from Shopify and Amazon go into QuickBooks or Xero as one summary per payout, posted by A2X or Link My Books (or Synder if you also take Stripe, PayPal or Square outside Shopify).
- Stock lives in one inventory system that pushes quantities to Shopify and Amazon and posts cost of sales to the accounts. Cin7 Core or Katana for a full system, Trunk if you only need quantities kept in step.
- Wholesale invoices are raised either in the accounting software itself or in the inventory system, never in Shopify, so they sit next to the marketplace summaries in the same ledger.
The rest of this section goes through each part, then answers the specific questions we see in search, and finishes with where Fintask fits when the off-the-shelf connectors do not cover your particular mix. If you only sell on Shopify, skip to the accounting tool reviews below.
Sales, Fees and Payouts: One Summary per Payout, per Channel
Shopify and Amazon both pay you in batches. A Shopify Payments payout bundles dozens of orders with fees and refunds netted off; an Amazon settlement does the same every two weeks, with FBA fees, advertising, reimbursements and reserves thrown in. If you post every order as its own invoice, nothing in the bank feed will ever match.
The fix is to post one journal or invoice per payout that splits the deposit into gross sales, refunds, fees, VAT and the net amount, then matches it to the bank line. Two tools do this well for Shopify and Amazon together:
- A2X covers Shopify, Amazon, Etsy, eBay, Walmart and PayPal and posts to QuickBooks Online, Xero or Sage. Single-channel plans start around USD 29 per month; the Multi plans that combine two or more channels start around USD 89 per month for 1,000 orders.
- Link My Books covers Shopify, Amazon, eBay, Etsy, Walmart, TikTok Shop, Square and WooCommerce and posts to Xero or QuickBooks Online. Plans start around USD 21 per month for 200 orders, and every plan includes all channels; the tiers differ by order volume and how far back it imports history. It is particularly strong on UK and EU VAT treatment, which matters for Irish sellers.
Either one gives your accountant a bank feed that reconciles in a click. If you also take Stripe, PayPal or Square payments outside Shopify (a WooCommerce site, invoices paid by card), Synder handles the widest list of gateways in one place. Intuit's free Shopify Connector only sees Shopify, so it is not a fit once Amazon is in the picture.
Details for the two accounting platforms are in our Shopify QuickBooks integration and Shopify Xero integration guides, and the wider hubs for QuickBooks integrations and Xero integrations.
Stock Sync Across Shopify, Amazon and Your Accounting
Neither QuickBooks Online nor Xero is built to be the stock record for a multi-channel brand. QuickBooks Online has basic inventory on its higher plans and Xero has simple tracked items, but neither will keep Shopify and Amazon quantities in step or handle bundles, multiple warehouses or a 3PL. So the rule is: pick one system of record for stock, and let it talk to everything else.
To sync inventory across Shopify, Amazon and QuickBooks without manual updates, the system of record is one of:
- Cin7 Core (formerly DEAR) for a full inventory and order system with native Shopify, Amazon, Xero and QuickBooks Online connections. It takes every sales order in from the channels, allocates and ships stock, pushes available quantities back out, and posts sales, purchases and cost of goods sold to the accounts. Cin7 Omni is the configurable, larger version with built-in EDI, 3PL links and multi-entity support, priced on request; the way it connects Shopify, Amazon, Xero and QuickBooks is the same idea at a bigger scale. See the Cin7 Shopify guide and the Cin7 Xero guide.
- Katana if you make or assemble what you sell. It has native QuickBooks Online and Xero integrations (sales orders become invoices, purchase orders become bills, stock value and manufacturing cost post across) plus Shopify and Amazon order sync.
- Zoho Inventory, inFlow or Unleashed as lower-cost inventory platforms with their own QuickBooks Online or Xero connections and Shopify and Amazon channel links. These are the budget-friendly options that plug into Shopify and QuickBooks without a separate middleware tool. AI forecasting apps such as Inventory Planner and Prediko sit on top of Shopify for demand planning rather than acting as the accounting link, so pair them with one of the above.
- Trunk if the only problem is overselling. It keeps quantities in step across Shopify, Amazon, eBay and Etsy in near real time, with bundles and safety stock, but it does not post anything to the accounts; keep A2X or Link My Books for that.
Whichever you choose, do not also let the accounting connector create items and quantities, or you will have two stock records that drift apart. More options are in our Shopify inventory sync guide.
Wholesale Invoices Alongside the Marketplace Channels
Wholesale is where the neat connector picture usually breaks. Retail customers pay through Shopify or Amazon in batches; wholesale customers get an invoice on 30-day terms, pay by bank transfer, and sometimes short-pay or take a settlement discount. Those invoices need to be real receivables in the ledger, not lines in a payout summary.
There are three workable patterns:
- Raise wholesale invoices in the inventory system. Cin7 Core, Katana and Unleashed all handle B2B orders with customer price lists and push each invoice to QuickBooks or Xero as a normal sales invoice. Stock is deducted in the same place as the Shopify and Amazon orders, so one system knows what is really available.
- Raise them directly in QuickBooks or Xero. Fine at low volume if the stock record is elsewhere or you are not tracking stock per invoice. The catch is that stock sold wholesale has to be deducted somewhere, so you end up with manual adjustments.
- Use Shopify B2B or a wholesale app. Shopify's own B2B features (on Plus) and wholesale apps can take the order, but net-terms invoices then need to reach the accounts as invoices, not as part of a payout. A2X and Link My Books summarise payouts, so B2B orders paid on account need a separate route into the ledger.
The best QuickBooks integration for a brand selling on Amazon, Shopify and wholesale at once is therefore a pair: A2X or Link My Books for the two marketplace channels, and Cin7 Core or Katana raising the wholesale invoices and owning stock, both posting into the same QuickBooks Online or Xero file. The same pair works for Xero. Where the wholesale side already runs on something else (a distributor's EDI, an older ERP, a spreadsheet of standing orders), that is the point at which a built-to-fit sync is cheaper than forcing it through an app that was not designed for it.
Reporting and FP&A on Top of Shopify and QuickBooks or Xero
Once the data is in the ledger, the next question is reporting: margin by channel, contribution by product after Amazon fees and advertising, cash forecast against the next settlement. Two groups of tools cover this, and neither covers both sides on its own:
- Financial analysis and FP&A tools such as Fathom, Syft Analytics and Jirav connect natively to QuickBooks Online and Xero and are strong for management reports, consolidation and forecasting. They see Shopify and Amazon only through what the accounting connector posted, so channel detail is as granular as your A2X or Link My Books mapping.
- E-commerce analytics tools such as Polar Analytics and Triple Whale connect natively to Shopify, Amazon and ad platforms and are strong on marketing and contribution margin, but they do not read the general ledger, so they will not tie to the accounts.
For BI tools with built-in connectors for both QuickBooks and Shopify, the honest answer is that general BI tools (Power BI, Looker Studio) reach both through third-party connectors or a data warehouse rather than out of the box. That is the route we take for clients who want one model: Shopify, Amazon and QuickBooks or Xero data landed in Microsoft Fabric and reported in Power BI, so marketing numbers and the ledger agree. Our Microsoft Fabric finance reporting guide shows what that looks like.
Straight Answers to the Questions People Ask
These are the exact questions this page is found for. Each gets a direct answer.
Which inventory control platforms integrate seamlessly with Shopify and automatically sync accounting data?
Cin7 Core, Katana, Unleashed, Zoho Inventory and inFlow all connect natively to Shopify and post to QuickBooks Online or Xero. Cin7 Core and Katana are the most complete; Zoho Inventory and inFlow are the cheaper options. Trunk syncs quantities only, with no accounting link.
How does Cin7 Omni integrate with Shopify, Amazon, Xero and QuickBooks to connect sales, warehouse and accounting?
Cin7 Omni pulls orders in from Shopify and Amazon, allocates and ships them from its warehouse module (including 3PL and EDI), pushes stock levels back to each channel, and posts sales invoices, purchase bills, payments and cost of goods sold to Xero or QuickBooks on a schedule you set. It is priced on request; Cin7 Core does the same for Shopify and Amazon from a published price (from about USD 349 per month) without the EDI and multi-entity layer.
Does DualEntry automatically sync transactions from Shopify, Stripe and Square directly into QuickBooks or Xero?
No. DualEntry is an ERP with its own general ledger, positioned as a replacement for QuickBooks or Xero rather than an add-on to them. Its integrations (Stripe is listed; Shopify and Square are not on its current integrations list) flow into DualEntry's own books. If you want to stay on QuickBooks or Xero, use A2X, Link My Books or Synder for Shopify and Stripe, and Link My Books or Synder for Square. Full detail in our A2X vs Synder vs DualEntry vs Link My Books vs Connex comparison.
What is the best QuickBooks integration for a brand selling on Amazon, Shopify and wholesale at once?
A2X or Link My Books for the Shopify and Amazon payouts, plus Cin7 Core or Katana to own stock and raise the wholesale invoices, all posting to the same QuickBooks Online file. There is no single app that does all three well.
How do I sync inventory across Shopify, Amazon and QuickBooks without manual updates?
Make one inventory system the record of truth (Cin7 Core, Katana, Zoho Inventory or inFlow), connect Shopify and Amazon to it so it pushes available quantities out, and let it post stock movements and cost of sales to QuickBooks. Do not run QuickBooks' own inventory in parallel.
Which accounting tools integrate most seamlessly with e-commerce platforms like Shopify, WooCommerce or Amazon?
QuickBooks Online and Xero, because every serious e-commerce connector (A2X, Link My Books, Synder, Webgility, Amaka) is built for them. Sage is supported by A2X and Synder. The native Shopify apps for QuickBooks and Xero work for a small single-channel store but lack multi-channel and payout-level detail.
Which end-to-end payment platform works with Shopify, WooCommerce and QuickBooks?
Stripe. Shopify Payments runs on Stripe, WooCommerce has an official Stripe gateway, and Stripe payouts post to QuickBooks through A2X, Link My Books or Synder. PayPal is the usual second gateway and is covered by the same connectors. See our Stripe QuickBooks and Stripe Xero guides.
What is the best accounting software for Shopify?
For an Irish, UK or EU store: Xero or QuickBooks Online, with the choice usually decided by what your accountant uses. Both have the full set of Shopify, Amazon and Stripe connectors above and handle multi-currency and VAT returns. If you are setting up in Ireland, our Shopify setup Ireland guide walks through VAT, payments and the accounting connection step by step.
Which BI or FP&A tools integrate with Shopify and the accounting system?
Fathom, Syft and Jirav for financial analysis on QuickBooks or Xero; Polar Analytics or Triple Whale for Shopify and Amazon marketing data; Power BI on a Fabric data model if you need the two to agree in one report.
What budget-friendly inventory platforms plug into Shopify and QuickBooks without extra middleware?
Zoho Inventory, inFlow and Katana's starter plan all have direct QuickBooks Online connections and Shopify channel links, so no separate integration tool is needed. Add a forecasting app (Inventory Planner, Prediko) on the Shopify side if you want AI demand planning.
Where Fintask Fits
Fintask is not another connector app. We are a Chartered Accountant-led automation firm in Ireland, and the work we do for online sellers starts where the apps above stop:
- The mix the apps do not cover. Wholesale orders arriving by EDI or email, a 3PL that reports stock in its own format, a marketplace A2X or Link My Books does not support, two legal entities sharing one Shopify store, or returns that come back through a different channel than the sale. We build the sync or the reconciliation for that specific gap, into your existing QuickBooks Online or Xero, and leave the standard connectors doing what they do well.
- Reconciliation that the connectors leave behind. Matching Amazon reserves and reimbursements, Shopify gift cards and partial refunds, multi-currency payouts and EU VAT OSS splits, with exceptions flagged for a person rather than silently posted.
- Reporting across channels and the ledger. Margin by channel and product after fees and advertising, from Shopify, Amazon and the accounts in one Power BI or Fabric model.
Two of the most common jobs are packaged at a fixed price: inventory sync with your accounting and per-product profit tracking. Everything else starts with a short call where we look at your channels, your accounting file and what is being retyped today, and tell you plainly whether an off-the-shelf app will do it or whether it needs building.

Book a call and we will map your channels to QuickBooks or Xero, tell you which connectors cover it, and quote the piece that needs building.
Best Shopify Accounting Integrations
Accounting integrations are the foundation of any Shopify automation stack. They ensure that every sale, refund, fee, and payout is recorded in your accounting software accurately and on time. The right tool depends on which accounting platform you use, how many orders you process, and whether you sell across multiple channels or currencies.
Here are the six best Shopify accounting integrations available in 2026, ranked by capability and value.
Intuit QuickBooks Connector (Shopify Connector by Intuit)
The Shopify Connector by Intuit is QuickBooks Online's native integration for Shopify. It is free, officially supported by Intuit, and available directly from the Shopify App Store.
What it does: The connector syncs Shopify orders, refunds, and payouts to QuickBooks Online. It creates invoices or sales receipts in QBO for each Shopify order and maps revenue, discounts, shipping, and tax to the corresponding QBO accounts. Payouts are matched to your bank feed for reconciliation.
Pricing: Free (included with any QuickBooks Online subscription).
Strengths:
- Zero cost -- no monthly fee beyond your existing QBO subscription
- Official Intuit product, so it is updated alongside QBO itself
- Straightforward setup with a guided mapping wizard
- Decent for single-channel, single-currency stores with moderate volume
Limitations:
- No multi-currency support -- a significant gap for European sellers
- No COGS or inventory tracking
- No support for Amazon, eBay, or other channels -- Shopify only
- Limited control over how data is summarised (per-order only, not per-payout)
- User reviews cite occasional sync delays and mapping inflexibility
Best for: Solo Shopify merchants using QuickBooks Online with a single currency and fewer than 100 orders per month who want a free, no-fuss connection.
A2X
A2X is the gold standard for e-commerce accounting integrations, trusted by thousands of accountants and bookkeepers worldwide. It creates per-payout summaries that break down every Shopify deposit into its components: gross sales, fees, refunds, discounts, shipping, and tax.
Pricing: From around USD 29/month for a single channel (Mini, 200 orders/month), rising with order volume. Multi-channel plans that combine Shopify with Amazon and others start around USD 89/month for 1,000 combined orders.
Accounting platforms supported: QuickBooks Online, Xero, Sage.
Strengths:
- Per-payout reconciliation that matches your bank feed exactly -- the easiest method for clean books
- COGS tracking on higher-tier plans
- Multi-channel support: Shopify, Amazon, eBay, Etsy, Walmart, BigCommerce
- Rated 4.8/5 across app stores -- consistently the highest-rated e-commerce accounting app
- Audit-ready output that accountants trust
Limitations:
- Multi-currency support is limited compared to some competitors
- Pricing is per channel unless you take a Multi plan, so Shopify plus Amazon costs more than the entry price suggests
- Setup requires careful account mapping -- not a one-click install
Best for: Growing to high-volume Shopify stores that want clean, per-payout accounting in QBO, Xero, or Sage. The go-to choice for merchants who work with an accountant or bookkeeper.
Link My Books
Link My Books does the same job as A2X -- one summarised entry per payout, matched to the bank feed -- and has become the usual A2X alternative for UK and Irish sellers because of how it handles VAT. It connects to Xero and QuickBooks Online.
Pricing: From around USD 21/month (200 orders/month). Higher tiers are priced by order volume; every plan includes all supported channels, and the difference between tiers is the order ceiling and how far back historical data is imported.
Accounting platforms supported: Xero, QuickBooks Online.
Strengths:
- Payout-level summaries for Shopify, Amazon, eBay, Etsy, Walmart, TikTok Shop, Square and WooCommerce
- Strong UK and EU VAT handling, including marketplace-collected VAT and OSS, which is where Irish sellers most often get Amazon wrong
- Guided setup wizard that maps accounts and tax rates for you
- All channels on every plan, so adding Amazon to Shopify does not force a plan change
Limitations:
- Xero and QuickBooks Online only -- no Sage
- Summaries only: no per-order detail in the accounts, and no stock or COGS tracking
- Wholesale and net-terms orders need another route into the ledger
Best for: Irish and UK brands selling on Shopify and Amazon together who want accurate VAT and a bank feed that reconciles, at a lower entry price than A2X.
Synder
Synder is a multi-platform accounting sync tool that connects over 20 payment and e-commerce platforms to your accounting software. It handles Shopify alongside Stripe, PayPal, Square, Amazon, Etsy, and more -- making it the most versatile option for merchants with complex payment stacks.
Pricing: EUR 20--200/month. The Medium plan (EUR 55/month) covers 1,000 transactions; the Scale plan (EUR 200/month) covers 50,000 transactions.
Accounting platforms supported: QuickBooks Online, QuickBooks Desktop, Xero, Sage.
Strengths:
- Connects 20+ platforms in a single dashboard -- ideal for merchants selling on Shopify, Amazon, and Etsy simultaneously
- Per-transaction or summary sync modes -- you choose the granularity
- Full multi-currency support with automatic exchange rate handling
- Smart Rules engine for automated categorisation of unusual transactions
- Inventory tracking on higher-tier plans
Limitations:
- The pricing scales steeply at high volumes -- EUR 200/month for the Scale plan
- The interface can feel overwhelming with 20+ connected platforms
- Some users report slower sync speeds compared to A2X
Best for: Multi-channel, multi-gateway merchants who need a single tool to consolidate Shopify, Amazon, Stripe, PayPal, and more into one accounting feed. Particularly strong for EU sellers dealing with multiple currencies.
Webgility
Webgility is a full accounting automation platform purpose-built for e-commerce. It goes beyond simple data sync -- Webgility automates the entire accounting workflow from order to reconciliation, including automated posting, tax mapping, and inventory updates.
Pricing: EUR 49--249/month. The Pro plan (EUR 99/month) covers most mid-sized stores; the Premium plan (EUR 249/month) adds advanced automation and priority support.
Accounting platforms supported: QuickBooks Online only (no Xero or Sage support).
Strengths:
- The deepest QuickBooks integration available -- automates posting, reconciliation, and reporting end-to-end
- Full inventory sync between Shopify and QuickBooks, including COGS and stock adjustments
- Multi-channel: Shopify, Amazon, eBay, Walmart, Etsy, WooCommerce
- Automated tax code mapping that handles US sales tax complexity well
- Dedicated onboarding support with guided setup
Limitations:
- QuickBooks Online only -- no Xero or Sage support, which limits its appeal for European merchants
- The most expensive option in this comparison at EUR 249/month for Premium
- Steeper learning curve due to the depth of automation features
Best for: High-volume QuickBooks Online users who want full end-to-end accounting automation, not just data sync. If your accounting platform is QBO and you want maximum automation, Webgility is the most powerful option available.
Amaka
Amaka offers a simple, affordable Shopify-to-accounting sync that is ideal for small stores that need basic automation without complexity. It syncs daily sales summaries to your accounting platform with minimal configuration.
Pricing: Free (up to 100 orders/month) or EUR 25/month for unlimited orders.
Accounting platforms supported: QuickBooks Online, Xero, MYOB.
Strengths:
- The most affordable option -- genuinely free for small stores
- Clean, simple interface with a setup process that takes under 10 minutes
- COGS tracking included on the paid plan
- Supports both QBO and Xero, making it versatile for European merchants
Limitations:
- No multi-currency support
- No multi-channel support -- Shopify, Square, or single-channel only
- Daily summary sync only -- no per-payout or per-order granularity
- Limited reporting and customisation compared to A2X or Synder
Best for: Solo merchants and small stores processing fewer than 100 orders per month who want a free or very low-cost way to get Shopify data into Xero or QuickBooks without manual entry.

- European-first: built for multi-currency, multi-country VAT, and EU regulatory requirements from the ground up
- Works alongside existing integrations (A2X, Synder, etc.) as an automation layer
Limitations:
- Not a direct Shopify-to-accounting data pipe -- FinTask is an automation layer that works on top of your integration stack
- Custom pricing means you need to contact the team for a quote
Best for: European merchants running multi-channel operations who want AI accounting tools with seamless Shopify integration -- not just data sync, but genuine automation of the accounting tasks that still require human judgement. Particularly strong for businesses already using Xero or QuickBooks that want to eliminate manual reconciliation and review. Two of the most-requested setups are available as fixed-scope packages: per-product profit tracking and inventory sync with your accounting.
Best Shopify Inventory Integrations
Accounting integrations handle the financial side, but if you sell physical products, you also need to track stock levels, COGS, and supply chain operations. Shopify's built-in inventory tracking is adequate for simple stores, but it falls short for businesses with manufacturing, multi-warehouse operations, or high SKU counts. Here are the best Shopify inventory integrations for 2026.
Katana
Katana is a cloud manufacturing and inventory management platform designed for makers and product-based businesses. It connects to Shopify for order management and to Xero or QuickBooks for accounting -- giving you a complete production-to-sale-to-books pipeline.
Pricing: From EUR 129/month (Starter plan). The Standard plan (EUR 349/month) adds advanced manufacturing features.
Key features:
- Manufacturing focus: bill of materials (BOM), production scheduling, raw material tracking, and shop floor management
- Real-time inventory: live stock levels across Shopify, Amazon, WooCommerce, and your physical warehouse
- COGS and landed cost tracking: accurate cost calculations including shipping, customs, and overhead
- Shopify integration: auto-sync orders, allocate stock, and update availability in real time
- Integrates with Xero and QuickBooks Online for accounting
Best for: Product-based businesses that manufacture or assemble goods and need to track raw materials, production costs, and finished goods inventory alongside their Shopify sales. If you have a BOM, Katana is purpose-built for your workflow.
Cin7
Cin7 (formerly DEAR Systems) is a comprehensive inventory management platform built for multi-channel e-commerce. It connects Shopify, Amazon, WooCommerce, eBay, and B2B sales channels to a single inventory hub, with native integrations to Xero and QuickBooks for accounting.
Pricing: From EUR 349/month (Cin7 Core Standard plan). Cin7 Omni pricing is on request.
Key features:
- Multi-channel inventory: centralised stock management across every sales channel with automatic quantity sync
- Warehouse management: pick, pack, and ship workflows with barcode scanning and 3PL integrations
- COGS journal entries: automated cost of goods sold sync to Xero via journal entries
- Invoice consolidation: group high-volume e-commerce invoices by day or month before syncing to Xero
- Manufacturing: production planning, BOM, and assembly tracking
Best for: Mid-sized to large e-commerce businesses selling across multiple channels that need enterprise-grade inventory management with deep Xero integration. See our full guide to Cin7 Shopify integration for a detailed setup walkthrough.
Trunk
Trunk is a lightweight inventory sync tool that keeps stock levels consistent across Shopify, Amazon, eBay, Etsy, Walmart, and other channels. It does not try to be a full inventory management platform -- it focuses on doing one thing well: preventing overselling by syncing quantities in real time.
Pricing: From approximately EUR 35/month for the Merchant plan.
Key features:
- Real-time quantity sync: stock level changes on one channel are reflected across all connected channels within minutes
- Bundling and kitting: create product bundles that automatically deduct component inventory when sold
- Safety stock: set buffer quantities per channel to avoid overselling during sync delays
- Simple setup: connect your channels and map your SKUs -- no complex configuration required
Best for: Multi-channel sellers who need reliable inventory sync without the complexity or cost of a full inventory management platform. If your main problem is overselling because stock levels are out of sync between Shopify and Amazon, Trunk solves it simply and affordably. See our guide to Shopify inventory sync for more options.
Best Shopify Payment Integrations
Payment integrations bridge the gap between your payment gateways and your accounting software. Shopify Payments (powered by Stripe) is the default, but many merchants also accept PayPal, manual bank transfers, and other gateways. Each gateway has its own fee structure, payout schedule, and reporting format -- which is why payment reconciliation is one of the most time-consuming tasks in e-commerce accounting.
Stripe Reconciliation
If you use Shopify Payments, you are already using Stripe under the hood. Stripe handles card processing, fee deduction, and payout batching. The challenge is reconciling Stripe payouts in your accounting software -- each deposit contains multiple orders with fees deducted, and the amounts rarely match individual Shopify orders.
Tools like A2X, Synder, and FinTask excel at Stripe reconciliation. They break down each payout into its components (gross sales, Stripe fees, refunds, net deposit) and post a matching entry to your accounting software. This means your bank deposit matches a single entry in your books, making reconciliation a one-click process.
PayPal Integration
PayPal adds another layer of complexity because it holds funds in a separate PayPal balance before transferring to your bank account. This creates a timing difference: Shopify records the sale immediately, but the cash may not reach your bank for days. You need a dedicated PayPal clearing account in your accounting software and an integration that tracks PayPal deposits separately from Shopify Payments deposits.
Synder handles PayPal particularly well, syncing PayPal transactions alongside Shopify and Stripe in a unified dashboard. A2X also supports PayPal reconciliation on its higher-tier plans.
Multi-Gateway Management
Merchants accepting payments through Shopify Payments, PayPal, Klarna, Apple Pay, and manual transfers need a separate clearing account for each gateway in their accounting software. Each gateway's payouts must be reconciled independently. The best accounting integrations (A2X, Synder, FinTask) handle multi-gateway setups natively -- creating separate summary entries for each payment method and matching them to the correct bank deposits.
For a detailed walkthrough of connecting Shopify's default payment gateway to your accounting, see our Shopify QuickBooks integration guide.
Shopify Integration Comparison Table

Key takeaway: There is no single "best" integration. The right choice depends on your accounting platform, order volume, number of sales channels, and whether you need inventory management alongside accounting sync. Read on for specific recommendations based on your business size.
If you are weighing A2X against Synder, Link My Books, Connex or DualEntry specifically, we keep a separate sourced comparison of Shopify and Amazon accounting sync tools: posting method, channels, current list prices and limits, each claim linked to the vendor's own site and dated.
Which Integration Should You Use?
Choosing the right Shopify integration depends on where you are in your growth journey. Here are concrete recommendations for three common scenarios.
Solo Store (EUR 0--20/month budget)
You are a solo founder or small team processing fewer than 100 orders per month on a single Shopify store. Your accounting is in QuickBooks Online or Xero, you sell in one currency, and you use Shopify Payments as your only gateway.
Recommended stack:
- Accounting: Shopify Connector by Intuit (free, QBO) or Amaka (free tier, Xero/QBO)
- Inventory: Shopify's built-in inventory tracking is sufficient at this scale
- Payments: Shopify Payments only -- no multi-gateway complexity
Total cost: EUR 0/month.
At this stage, your priority is getting data into your accounting software without manual entry. The free tools handle the basics. Upgrade when you exceed 100 orders/month, add a second sales channel, or start selling in multiple currencies.
Growing Store (EUR 20--100/month budget)
You are processing 100--1,000 orders per month, selling on Shopify and possibly Amazon or Etsy, accepting PayPal alongside Shopify Payments, and your accountant wants clean per-payout reconciliation.
Recommended stack:
- Accounting: A2X or Link My Books for per-payout accounting in Xero or QBO (Link My Books if VAT on Amazon is your headache), or Synder (from EUR 20/month) if you need multi-gateway consolidation
- Inventory: Trunk (~EUR 35/month) if you sell on multiple channels and need quantity sync; otherwise Shopify's built-in tracking is still viable
- Payments: Your accounting integration (A2X or Synder) handles Stripe and PayPal reconciliation
Total cost: EUR 20--55/month.
This is the sweet spot where a proper accounting integration pays for itself within the first month. The time saved on manual reconciliation alone (typically 3--5 hours per week) far exceeds the subscription cost.
High Volume (EUR 100--250+/month budget)
You are processing 1,000+ orders per month across multiple channels, dealing with multiple currencies, managing physical inventory across warehouses, and your finance team needs audit-ready books with automated workflows.
Recommended stack:
- Accounting: A2X Multi or Link My Books for Shopify plus Amazon payouts, or Webgility (EUR 99--249/month, QBO only) for deep QuickBooks automation
- Inventory: Katana (from EUR 129/month) for manufacturing, or Cin7 (from EUR 349/month) for enterprise multi-channel inventory management
- AI automation layer: FinTask for intelligent reconciliation, anomaly detection, and automated categorisation on top of your existing integration stack
- Payments: Multi-gateway reconciliation handled by your accounting integration plus FinTask's anomaly detection
Total cost: EUR 150--500+/month depending on inventory needs.
At this scale, the cost of errors and manual processes dwarfs the subscription fees. A single undetected duplicate payment or missed VAT filing costs more than a year of integration subscriptions. Invest in the full stack and let your finance team focus on analysis rather than data entry.

Frequently Asked Questions
What is the best Shopify QuickBooks integration?
For a small single-channel store, Intuit's free Shopify Connector is enough. Once you want payouts that match the bank feed, or you add Amazon, A2X or Link My Books is the best Shopify QuickBooks integration: each posts one summary per payout with sales, fees, refunds and VAT split out. Synder is the pick if you also take Stripe, PayPal or Square outside Shopify, and Webgility if you want the deepest QuickBooks-only automation including inventory.
What is the best accounting software for Shopify?
QuickBooks Online or Xero. Every serious Shopify connector (A2X, Link My Books, Synder, Webgility, Amaka) is built for those two, both handle multi-currency and VAT returns, and most Irish and UK accountants work in one of them. Choose whichever your accountant uses; the Shopify, Amazon and Stripe integrations are equally good on both.
What is the best QuickBooks integration for a brand selling on Shopify, Amazon and wholesale at once?
A pair of tools, not one. A2X or Link My Books posts the Shopify and Amazon payouts to QuickBooks Online as reconciled summaries. Cin7 Core or Katana owns the stock, pushes quantities to both channels, and raises the wholesale invoices, which post to QuickBooks as normal receivables. If part of the wholesale side runs on EDI or an older system the apps do not reach, Fintask builds that piece of the sync.
Does DualEntry sync Shopify, Stripe and Square transactions into QuickBooks or Xero?
No. DualEntry is an ERP with its own general ledger and is positioned as a replacement for QuickBooks or Xero, not an add-on. Its integrations flow into DualEntry's own books; Stripe is on its integrations list, Shopify and Square currently are not. To stay on QuickBooks or Xero, use A2X, Link My Books or Synder for Shopify and Stripe, and Link My Books or Synder for Square.
How do I sync inventory across Shopify, Amazon and QuickBooks without manual updates?
Make one inventory system the record of truth, such as Cin7 Core, Katana, Zoho Inventory or inFlow. Connect Shopify and Amazon to it so it pushes available quantities to both channels, and let it post stock movements and cost of goods sold to QuickBooks Online. Do not run QuickBooks' own inventory alongside it, or the two records will drift.
Does Shopify integrate with Xero?
Yes. Shopify integrates with Xero through third-party apps including A2X, Amaka, Synder, and FinTask. There is also a native Xero integration available in the Shopify App Store, though it is more limited in features (no multi-currency, no COGS tracking). For most stores processing more than 50 orders per month, a dedicated integration app provides more reliable and detailed accounting sync. See our full guide to Shopify Xero integration for a detailed comparison.
What is the Shopify connector by Intuit?
The Shopify Connector by Intuit is the official, free integration between Shopify and QuickBooks Online. It syncs orders, refunds, and payouts from Shopify to QBO, creating sales receipts or invoices and mapping revenue, tax, discounts, and fees to the corresponding accounts. It is a solid free option for single-channel, single-currency stores, but it lacks multi-currency support, COGS tracking, and multi-channel capabilities.
Can I sync Shopify inventory with QuickBooks?
Basic inventory sync is available through tools like Webgility (EUR 49--249/month), which provides full two-way inventory sync between Shopify and QuickBooks Online including stock levels, COGS, and product data. The free Shopify Connector by Intuit does not include inventory sync. For more advanced inventory management (manufacturing, multi-warehouse, BOM), platforms like Katana and Cin7 connect both Shopify and QuickBooks with dedicated inventory tracking.
