AP Recovery Audit
Accounts payable recovery audit without the contingency firm.
We encode your vendor rules — contract rates, fuel surcharges, pass-through terms — into a continuous pre-payment audit that flags overcharges before the money leaves.
Built with the leading AI platforms
The broken Friday
The bills keep coming. The rules live in someone’s head.
From AP inboxes we have sat inside: PE-backed services businesses running thousands of vendor invoices a month, with contract rates nobody re-checks.
Invoices arrive by email, with no PO behind them
Vendor bills land in an inbox, get keyed by hand, and routed into an ERP nobody fully trusts. First, someone works out what the bill even is.
The duplicate that looks different every time
Same vendor, same service, new invoice number, slightly different amount. Catching it means remembering every bill you already paid — thousands a month, no two alike.
Contract rates nobody re-checks
The rate sheet says one number, the invoice says another. Case-vs-each pricing, fuel surcharges, fees that appear mid-contract. Somebody has to know the item to catch it.
Pass-through charges you eat instead of bill
Fees recoverable from customers go unapplied because nobody can tie the charge to the contract clause fast enough. The margin leak is quiet, and it compounds.
The audit that shows up a year late
A contingency firm sweeps last year’s payments, takes a percentage of what it recovers, and leaves. Next month the same leaks reopen, because nothing about the process changed.
What manual costs
The leak is a line item, not a feeling.
Reported operating examples show where manual work adds up. Your audit establishes the workload, error rates, and costs in your business.
From anonymized engagements — waste services, healthcare supply, distribution
How it works
We encode your exceptions.
No new system for your team to learn. The rules your best AP person carries in their head become the audit.
- 01
Map the rules
We write down every rule a bill gets judged by: contract rates, surcharge tables, unit-of-measure quirks, expiring credits. Tribal knowledge becomes a rule set — yours to keep.
- 02
Encode the audit
Build checks against the available invoice data and agreed rules, then test coverage and exception handling with your team. Required payment approvals remain part of the workflow.
- 03
Run it every week
Run checks on an agreed cadence and report potential overcharges and price changes for review. Coverage depends on timely invoice data, current contract terms, and the rules validated with your team.
Review past payments and build recurring checks.
Contingency recovery firms audit twelve months of payments, take a percentage of what they claw back, and leave the process exactly as they found it. The leaks reopen before their invoice arrives.
We can build checks around your vendor rules and connect them to the AP workflow you use. The scope defines invoice coverage, exception routing, and review requirements.
