Diagnostic goal: Understand the merchant, invoice number, dates, tax, currency, totals, and line items commonly extracted from invoices.

Identify the failure before changing the record

For reviewers checking AI-extracted invoice data, the target is to focus attention on fields that affect matching and reporting. First determine whether the source is weak, the extracted value is uncertain, the document belongs to another transaction or the workflow context is missing. Correcting a field before identifying the cause can hide the evidence needed to prevent the same error.

Test	Evidence required
Supplier and invoice number are correct.	Verify supplier identity before accepting similarly named merchants.
Date meanings are explicit.	Distinguish invoice date, due date, and payment date.
Totals reconcile to the document.	Check tax and total arithmetic against the source.
