Field notes
The workflow accepts a supplier-transactions CSV with up to 5,000 rows and helps map custom supplier, invoice, and amount columns before checking the ledger. Its rules distinguish repeated payments with separate payment IDs, matching references with different amounts, and negative credits. Findings are presented as review leads rather than claimed savings, with currencies separated and source rows retained for the downloadable report.
