AP Automation for Industrial Distributors & Wholesalers
Distribution AP is a matching problem wearing an invoice costume: every supplier invoice needs a PO lookup and line-by-line SKU and unit-of-measure resolution — the supplier bills boxes, your ERP counts eaches. We built the pipeline that does it automatically for ~1,500 invoices a month, with a gate that caught a $23,908 error on its own.
Key Takeaway
Distribution AP is a matching problem wearing an invoice costume: every supplier invoice needs a PO lookup and line-by-line SKU and unit-of-measure resolution — the supplier bills boxes, your ERP counts eaches. We built the pipeline that does it automatically for ~1,500 invoices a month, with a gate that caught a $23,908 error on its own.
Why Distribution AP Is Harder Than It Looks
A distributor's supplier invoice isn't a document to approve — it's a matching problem. Fifty lines, each needing the right PO, the right SKU (under the supplier's part number, not yours), and the right unit of measure: the supplier bills a case of 12, your ERP counts eaches, and the price only reconciles if the conversion is right. Multiply by hundreds of invoices a month and AP becomes a team of people doing lookups — with the expensive errors being precisely the ones that slip through tired eyes.
Generic invoice-scanning tools stop at extraction. Extraction is the easy third of the problem; resolution against your live ERP and line-level matching are where distributor AP actually lives.
The Production Build Behind This Page
For a Canadian industrial safety distributor processing ~1,500 supplier invoices a month, we built a pipeline that extracts each invoice with AI, resolves vendor and PO against the live ERP in real time, matches lines deterministically — SKU by SKU, unit-of-measure by unit-of-measure — with AI as fallback for the inconsistent cases, and gates every invoice through a mathematical reconciliation check before it can post. One line in dispute (a damaged-parts credit, say) doesn't hold up the other 49.
The gate earned its keep immediately: it caught a $23,908 extraction error automatically in its first production run. Read the full case study.
What This Changes for a Distributor
AP stops being a keying team and becomes an exceptions team: the clean majority of invoices flow through untouched, and human attention goes only where the match genuinely fails. Price creep gets caught line-by-line against the PO instead of surfacing in margin reviews months later. And the accuracy gate means the automation checks its own work — the errors AI extraction inevitably makes get caught by mathematics, not by a supplier statement.
The production build runs against Infor CloudSuite Distribution; the same architecture applies to Business Central and Dynamics 365 F&O, swapping only the ERP-facing adapter.

Put your volume into the AP cost-per-invoice calculator — it benchmarks you against published industry figures — then take the free assessment. If your team is keying invoices next to an ERP that already knows every PO, the gap is a build, not another scanning tool.
Frequently Asked Questions
Our suppliers' part numbers don't match our SKUs. How does matching work?
Resolution is half the build: vendor part numbers map to your SKUs through the ERP's own cross-references, learned aliases and — for the genuinely inconsistent cases — an AI fallback whose suggestions are confirmed by a human and remembered. The deterministic path handles the clean majority; nothing posts on an unverified guess.
What about unit-of-measure mismatches?
They're treated as first-class matching logic, not an edge case — supplier bills in cases, ERP counts eaches, and the conversion is checked line-by-line with the price. UOM mismatch is one of the most common sources of silent overpayment in distribution AP.
We're not on Infor CloudSuite. Does this apply to us?
Yes. The matching architecture is ERP-agnostic — the production build happens to run against CloudSuite Distribution, and the same pipeline applies to Business Central, D365 F&O and comparable systems by swapping the ERP-facing API adapter.
How do we know the AI extraction hasn't misread an invoice?
Because every invoice must pass a mathematical reconciliation gate — extracted lines, quantities and totals have to balance against the PO and each other before posting is possible. That gate caught a $23,908 extraction error automatically in its first production run; that's the design working as intended.

Accounts Payable Automation for Business Central and Dynamics 365 F&O
Business Central and D365 F&O know which purchase orders are open. They don't know that a supplier billed in cases when the PO ordered eaches, or that one damaged-parts credit memo on a consolidated invoice shouldn't hold up the other 49 lines. Here's the matching architecture that fixes that, from a production build.
