Automated AP pipeline that captures invoices from any source, matches them against POs and receipts, and pays vendors with zero manual keying.
A manufacturer’s accounts-payable load is heavy and unforgiving: hundreds of invoices a month for raw material, components, MRO supplies, tooling, and freight, each one needing to be matched against a purchase order and a receiving record before it is paid. Done manually it costs $15–26 per invoice in keying, routing, and follow-up, and the second-order pain is worse — late fees on missed due dates, duplicate payments to the same vendor, and overpayments where the invoice quantity does not match what the dock actually received. Three-way-match automation ingests invoices from any source, matches PO to receipt to invoice, auto-approves the clean ones, and routes only genuine exceptions — price or quantity mismatches — to a human. For a shop floor where the receiving record is the source of truth, it closes the gap between what was ordered, what arrived, and what you are being billed, and it stops paying for material that never showed up.
A mid-size manufacturer processing several hundred invoices a month moved to automated capture and three-way matching; clean invoices that tie to the PO and the receiver now auto-approve, and buyers only touch the price/quantity exceptions. A metal-products shop caught a recurring overbilling where a supplier invoiced full PO quantity on partial shipments — the match flagged the receiver gap every time. A contract manufacturer eliminated duplicate payments by having the system detect same-vendor, same-amount invoices before release, recovering leakage that had been quietly written off.
Ramp Bill Pay if you also want a corporate card (free, no monthly fee). Bill.com if you process >200 invoices/month and need formal approval chains. Stampli if you have a long approval matrix. Reducto as a custom OCR feeder into QBO/Xero if your invoices are unusual.
Most platforms give you a dedicated AP email address (ap-yourco@bill.com). Forward your vendor invoice emails there. Add a Drive watch folder for scanned PDFs. The AI handles the rest.
For 3-way matching to work, your POs need to live somewhere the platform can read. Most integrate with QuickBooks Online, Xero, NetSuite. If you use a separate procurement system, an n8n bridge often works.
Set dollar-threshold-based routing. Example: <$500 auto-approve if PO matches, $500-5K route to department head, >$5K route to CFO. The platform handles the rest.
ACH is free or near-free. Virtual cards earn rebate. International wires via Wise or platform-native wire. Set defaults per vendor.
Process 30 invoices through the new system while still doing them manually. Compare for accuracy, catch edge cases (utility bills with no PO, multi-PO invoices, foreign currency). Adjust rules. Then cut over.
Watch two metrics weekly: average cycle time from receipt to payment, and the % of invoices that hit an exception. Aim for cycle time under 3 days and exception rate under 10%.

Auto-approve when invoice matches PO and receiver within tolerance on price (±[%]) and quantity (±[units]). Route to a buyer when: quantity invoiced exceeds quantity received; unit price exceeds PO price beyond tolerance; no receiver exists yet (goods not logged); PO is closed/over-released; or no PO exists (non-PO spend → approval workflow by amount). Hold and flag any suspected duplicate (same vendor + amount + invoice #/date proximity) before payment. Every exception carries the PO, receiver, and invoice side-by-side.
Hi [Vendor], reviewing invoice [#] against PO [#]. We show a discrepancy: PO/received quantity is [X] but the invoice bills [Y] (or: PO unit price [$] vs invoiced [$]). Could you confirm and issue a corrected invoice or credit for the difference? We are ready to pay the matched portion of [$] now and will release the balance on the correction. Receiver and PO attached for reference. Thanks — [AP contact].
From the invoice and matched PO, suggest GL coding: assign each line to the correct account (raw material by type, MRO, tooling, freight-in, etc.), cost center, and — where applicable — the job/work order it should be charged to. Use our chart of accounts and prior coding for this vendor as the pattern. Flag any line you cannot confidently code as NEEDS REVIEW rather than guessing. Output: line → account → cost center → job → confidence. A human approves before posting.
IF invoice_amount < 500 AND po_match = true THEN auto_approve IF invoice_amount BETWEEN 500 AND 5000 THEN route_to(department_head) IF invoice_amount > 5000 THEN route_to(cfo) IF po_match = false THEN route_to(buyer) FOR clarification
For each new vendor: capture W-9 (US) or W-8 (intl) on platform, set ACH or wire details, set default GL account, set approval workflow, set payment terms (NET 30 default). Do not pay any new vendor outside platform — every exception becomes a duplicate-payment risk.

Skip if you process fewer than 20 invoices/month — the platform overhead is not worth it. Skip if you operate primarily on credit cards (use Ramp card management instead). Skip if your invoices come from one or two vendors who already provide structured EDI feeds.
