Best for

LeakScan

Live

Scans your accounts-payable export in the browser for duplicate vendor payments, and the file never leaves the tab. Built for finance teams doing AP audits, not general spreadsheet work.

Data stays with youCan export my data
What to know▼
How it works
Scans an AP export (CSV/Excel) in the browser for suspected duplicate vendor payments — same invoice paid twice, invoice number variants, duplicate payment references, unapplied credits — and produces a CFO-ready HTML report plus Excel export.
What's different
Runs entirely in the browser under CSP that blocks outbound requests, so the file never leaves the tab.
Best for
Finance teams running accounts-payable audits.
Watch out
The reported result (found $38,125 of planted duplicates, 5/5, with zero false alarms) comes from a blind test the vendor ran itself, not an independent audit.
