AR Automation for Xero: What Invoice Reminders Do, and 9 Tools for Xero Users

AR automation for Xero is the most crowded corner of the market, and the cheapest. Most Xero businesses need a tool, not a build: Chaser and Paidnice for reminders that read replies, Satago or Credit-IQ for low-cost scheduled chasing. The deciding questions are who approves what goes out, and what happens to a disputed invoice.

Vendor sites checked 8 November 2026. "Not stated" means the vendor's own pages do not say, which is different from "No". "Person approves" means the vendor's page says an email the software drafted waits for a person before it goes. Full sourcing rule on the compare pages.

• Invoice reminders. "You can create up to five reminders", before or after the due date, with presets at 7, 14 and 21 days source. Reminders can be turned on or off per invoice source.
• They stop when paid. "Once a payment's matched, the reminders stop" source.
• Statements. Activity statements for a date range, or outstanding statements that show only what is owed source.
• JAX. Xero's AI drafts and sends invoices today. A chasing agent and follow-up plans "based on each customer's payment history" are described by Xero staff as in development on its product ideas forum source. Treat that as roadmap.

What it leaves to people: every reply, every "we'll pay Friday", every "this invoice is wrong". The reminder schedule is fixed at five steps by day, and a disputed invoice keeps getting reminders until someone switches them off.

Published prices first, then the quote-only platforms. Facts read on 8 November 2026.

A London tool, priced by turnover: Compact from £199 a month under £4 million revenue with four users, Core from £599 under £10 million, Complete from £899 under £100 million, 10% off yearly source. It "syncs with Xero once every day and before payment reminder emails are sent out" source. The AI reads each debtor's email, detects a promise, dispute or document request, and drafts a reply you send with one click; an expected payment date pauses chasing and it resumes after. Limits: disputed invoices are paused by hand; the scheduled reminders themselves send on their own.

Built for Xero and QuickBooks, priced by invoice volume with no seat fees: Essentials from £49, US$69 or €59 a month for 150 invoices, Pro from £74 source. "Paidnice reads every reply to your reminders, logs the promised date and drafts your answer", and "each drafted reply waits for a person to approve or edit it" unless you pre-approve a type source. A dispute pauses reminders; the owner is emailed if a promise breaks. It also adds late fees and interest to overdue invoices in Xero, including UK statutory interest that follows the Bank of England base rate source. Limits: Business Central, NetSuite and Sage Intacct only on the Custom plan from US$999 a month.

A UK credit control, credit-risk and invoice finance tool for small and medium businesses: Basic £45 a month or £450 a year with 100 email reminders, Premium £80, Platinum £200 source. "Two-way sync" with Xero source. Limits: rule-based reminders with no AI reading or drafting stated, no dispute module, no promise-to-pay record on the pages we read.

A Cardiff AR tool "Powered by Atradius", from £55 a month plus VAT for 100 invoices (£49 billed annually) source. It connects read-only through a connector to Xero, QuickBooks, Sage and others. A promise to pay moves the remaining reminder steps past the agreed date, replies are captured and linked to the reminder, and disputes are logged with a reason source. Limits: no AI; "additional fees may apply for some ERP synchronisation"; the page does not say a dispute stops the reminders.

A London order-to-cash platform priced per user by turnover: Business Pay at $650 a month per user, Business Plus $1,245, Enterprise custom, with "fully automated agent runs" charged separately by token use source source. "Real-time, two-way" sync with Xero; a collections inbox with drafted replies; disputes in one workspace with reason codes. You choose the autonomy level: "Insights", "a Copilot to draft work for you, or execute independently" source. Limits: per-user pricing climbs fast; Business Central and NetSuite are Enterprise only.

Xero is on every Upflow plan with real-time sync source. A flagged dispute pauses reminders; the AI reads replies and logs promises; each agent skill can suggest or run on its own. Limits: no published figures, Starter covers up to $10M of invoiced revenue, and the Collections Agent is on Scale and above.

Three mid-market platforms that list Xero beside the bigger ERPs. Invoiced syncs both ways and pauses chasing on a promise source. Gaviti connects through its help-centre setup with disputes, promises and a portal source. Monk syncs customers, invoices and payments from Xero, reads every reply and pauses follow-up on a disputed line source. All three are quote only and sell autonomy as the goal; for most Xero businesses they are more platform than the ledger needs.

Reviews read in full on Software Advice.

"like least about updating contact details that even being added from Xero we still have to go to Chase to tick every new contact on that customer to be on list of chasing reminders."

Chaser reviewer, marketing and advertising, 2-10 employees, Software Advice, December 2020. Read the review

"When our clients respond to chaser emails, we cannot reply directly. We have to re-type their address in order to send a response to them and sometimes I forget to do so which results in a bounce back."

Chaser reviewer, IT and services, 11-50 employees, Software Advice, December 2020. Read the review

"The only issue I have with Upflow is that our customers/agents often perceive my emails as a spam, seeing that my address is different: reminders@upflow.io"

Upflow reviewer, transportation, 1001-5000 employees, Software Advice, March 2020. Read the review

Both Chaser reviews are from 2020, and both vendors may have fixed these since. They are still the right questions to ask in a demo: do new Xero contacts join the chase on their own, and whose address does the customer see?

1. The sync is daily, or not stated. Chaser syncs once a day and before each run; most others do not say. A payment made at 9am can still get a reminder at 10am.
2. Disputes stop the chase in three of nine. Paidnice, Upflow and Monk say so. Elsewhere someone has to pause it.
3. Approval is a setting, not a rule. Paidnice, Kolleno, Upflow and Invoiced all let you switch it off, and several sell that as progress.
4. One organisation at a time. Groups with several Xero organisations, or Xero beside another ERP, end up with one tool per ledger.
5. Statutory interest is rarely computed. Paidnice adds late fees and interest to the invoice in Xero source; the others leave it to you. In Ireland the rate is 10.4% from 1 July 2026; in the UK, 8% plus the Bank of England base rate.

Most Xero businesses should buy a tool from the table. We build when the ledger, the disputes or the approval rule do not fit one.

1. Read Xero, never write to it. Open invoices, customers, contacts, credit notes and payments come in through the Xero API, for every organisation in the group. The agent writes only to its own tables on your cloud; cash application is untouched unless you ask for it.
2. One queue, ranked every morning. Every overdue invoice gets a stage from your rules (days overdue, balance, broken promises), and the queue shows who to chase today and why.
3. Drafts wait for a person. Each chase is drafted at the right stage, in your words, and sits in an approval queue. Nothing is sent until someone approves it. Auto-send exists only for a template an admin switches on, one at a time.
4. Replies become the next step. Every reply is read and sorted: paid, promise to pay, dispute, query, bounce. A promise becomes a dated follow-up. A dispute stops the chase and goes to the account owner with the thread attached; chasing resumes only when it is closed.
5. Everything logged against the invoice. Every email, reply, promise and note sits on the invoice and the customer, not in a personal inbox. Escalation runs on rules you set, to named people.

Two production builds sit behind this pattern: a US insurance services group on Business Central with $11.8M of receivables across 7,700 invoices and 1,200 customers in one queue, and a €30M Norwegian equipment rental group with a one-person AR team, where every email is drafted by AI and approved by a person. You can click through the same queue on fictional data in the AR demo.

Minimum engagement $2,500; fixed price after a scoping call. The DSO calculator shows what a day of DSO is worth to you.

1. How many overdue invoices a month? Under 50, start with Xero's reminders.
2. Do customers reply with reasons? If yes, pick a tool that reads replies: Chaser, Paidnice, Kolleno, Upflow, Invoiced or Monk.
3. Who approves what goes out? Paidnice by default; Chaser for AI replies.
4. Do you charge late-payment interest? Paidnice adds it to the invoice in Xero.
5. Is Xero your only ledger? If not, check each tool handles every company you run.
