Provide paid-bill or vendor-payment rows with credentials, bank data, tax IDs, customer data, employee data, and private notes removed.
VendorLeak duplicate payment screen
Find payment pairs worth verifying.

A bounded screen
Transparent evidence, not a black-box conclusion.
You keep access to your systems. We work from a sanitized CSV and return candidates your team can verify against source records.
Screen matching evidence
We compare normalized vendor, amount, currency, date, invoice reference, and description fields for exact and possible duplicate patterns.
Verify the candidates
You receive ranked findings, exact source rows, confidence labels, and a checklist for checking invoices, credits, reversals, and legitimate repeats.
Exact scope
Clear inputs. Clear limits.
The pilot is designed for a small business that can export a clean file and wants a transparent first pass without installing software.

What columns are useful?
Vendor, amount, currency, payment date, invoice reference, and description are the core evidence fields. A stable row ID helps us point back to the exact source record.
Does a flag prove we paid twice?
No. Every result is a review candidate. Your team must verify the original invoice, payment record, credits, reversals, refunds, split payments, subscriptions, and legitimate repeat purchases before taking action.
Do you need access to our accounting system?
No. This pilot accepts one sanitized CSV only. Do not share credentials, tokens, bank or card data, tax identifiers, customer information, employee information, attachments, or native accounting backups.
What happens if the file is outside scope?
We confirm fit before processing. If the export cannot be safely sanitized or the request requires contract interpretation, a formal accounting opinion, recovery work, or a fraud investigation, the pilot is not a fit.
Start with the file you already control.
Request the fixed-scope pilot through Contra. We confirm fit before any sanitized CSV is processed.
