AP automation processes invoices, and AllCaps checks whether those invoices comply with the contract behind them. Most finance teams need both: AP automation moves invoices to payment, and AllCaps audits commercial terms that a purchase order match cannot see.
An invoice can match its purchase order and pass every approval while still using the wrong contracted rate, missing a discount, exceeding a cap, or applying a fee the contract does not allow. AP automation is built for speed and control in the payment process. AllCaps is built to test the commercial terms, and it sits alongside your AP system.
This describes each category in general. Individual products vary, so confirm specific capabilities with each provider.
| Area | AllCaps | AP automation |
|---|---|---|
| Primary job | Audit invoices against the governing contract. | Capture, code, route, approve, and pay invoices. |
| Invoice is checked against | Contracts, amendments, rate cards, and commercial schedules. | Purchase orders, goods receipts, and approval rules. |
| Typical issues found | Wrong contracted rates, missed discounts, exceeded caps, disallowed fees, and unclaimed credits. | Duplicates, quantity and price differences against the PO, and missing approvals. |
| Where it is strongest | Commercial-term accuracy, with evidence tied to contract clauses. | Processing speed, workflow control, and payment efficiency. |
| Where it stops | It does not process, approve, or pay invoices. | It generally relies on the PO being right, and does not read every amendment and rate card. |
| Output | Evidence-backed findings with contract and clause support. | Approved invoices posted to the ERP and scheduled for payment. |
| Customer invoices | Also audits invoices you send against customer contracts. | Focused on invoices you receive. |
Send up to three governing contracts, amendments or rate cards, and up to 100 historical invoices. AllCaps returns evidence-backed findings with contract and clause support for material issues.
No. AllCaps is a contract-level audit layer that works alongside AP automation and your ERP. Your AP system keeps processing and paying invoices.
A three-way match compares the invoice with the PO and goods receipt, so it passes when all three agree. It misses cases where the PO itself is out of date against the contract, or where a discount, cap, or credit in the contract was never applied.
Some platforms have added contract-related checks, and coverage varies. Ask how each one handles amendments, rate cards, tiered pricing, and credits, and whether findings cite the contract clause.
Not to start. The Proof Audit uses contracts and historical invoices as PDFs or standard exports, with no integration required.
Yes. AllCaps also checks customer invoices against customer contracts for underbilling and incorrect commercial terms. AP automation is generally focused on invoices you receive.
AllCaps starts with a one-time Proof Audit fee, scoped and priced to your contracts and invoices. Ongoing audit is a subscription based on contract and invoice volume.
