Duplicate Invoice Evidence Screen

Flag possible duplicate invoices using stable evidence without deleting legitimate recurring bills.

What to provide

Authorized invoice export, supplier IDs, invoice numbers, amounts, currency, dates and original documents.

Workflow

1. Normalize only approved comparison fields while retaining originals. Never merge suppliers with similar names.
2. Group exact supplier/invoice-number matches, then identify weaker amount/date similarities separately.
3. Compare source documents and credit/reissue references. Recurring same-amount invoices are not proof of duplication.
4. Return candidate pairs with confidence reasons for review. Do not delete, pay, refund or mark invoices fraudulent.

Output contract

pair | supplier ID | invoice number | amount/currency | date | match strength | source distinction | reviewer

Fictional acceptance test

Fictional supplierS 1 has invoice 7 twice, same amount/date: flag exact duplicate candidate. Invoice 8 next month same amount isweak similarity, not a confirmed duplicate.

Review gates and limits
