How it works
Export your payables
A standard CSV or Excel export from QuickBooks, Sage, NetSuite or your ERP. Five minutes, read-only, nothing in your books changes.
Scan it in your browser
The free checker reads the file on your own computer and flags likely duplicate payments and unapplied credits, with dollar amounts.
Recover on contingency
If the scan finds real money, we verify every finding by hand and prepare the claim paperwork in your team's voice, sent from an address on your own domain. Your team approves every claim and follows up with your suppliers - and every message sent is logged where you can see it. Our fee is a percentage of what is actually recovered - nothing recovered, nothing owed.
What the checker looks for
- Exact duplicates - the same invoice number paid twice to the same supplier.
- Mis-keyed duplicates - one digit off, a transposed pair, an extra zero; keyed twice, paid twice.
- Unapplied credit memos - supplier credits sitting on the books that were never taken.
- Repeating same-amount charges - possible double-billed recurring items, flagged for review, not counted as errors.
Every finding is reviewed by a human before anything is claimed. The checker never contacts your suppliers.
Your data stays yours
- The scan runs entirely inside your browser. Your file is never uploaded, and this site has no server that could receive it.
- No analytics, no tracking scripts, no third-party fonts or pixels on this site.
- Try it offline: load the checker, disconnect from the internet, and scan. It works the same.
- The downloadable sample ledger is fictional data, so you can test everything without touching real numbers.
Who it is for
Businesses with enough supplier spend that one duplicate payment is real money - distributors, contractors, manufacturers, multi-location operators. If you pay hundreds of invoices a month, mistakes are not a matter of if. Every one of them is recoverable with the right evidence.
