What this scan does and does not check

This free scan checks for exact duplicate payments, likely duplicate payments (same vendor and amount, close dates), and unapplied credit memos. A full audit also matches supplier statements, checks pricing against contracts, and reviews 2-4 years of history with a human verifying every finding. A clean scan does not prove a clean ledger.
