Compare a written price with an invoice line. Keep identifiers, quantities and row references visible. An unmatched fee stays marked for review instead of being silently approved.

A proposed workflow for operators who need to know not just what was billed differently, but what actually came back. The interactive example is fictional; private imports are not available yet.
QUOTE → INVOICE
Name what is in question

Wait for the receipt
Link a later credit-note line to the case. Count only the observed amount as verified; leave any remainder outstanding for a human to review.
