OpsProof Tools builds local-first CSV review packs for AP and payment workflows: duplicate bills, payment matching, bank-feed reconciliation, and header readiness.

Start with the free AP Payment Hold-List Demo + Header Fit Checker. It runs in your browser with fake/sample data first, so you can see whether your CSV headers are ready before sending anything.

If you want help mapping your exports, choose AP CSV Column Mapping & First-Run Review. For the first pass, use header-only exports, fake rows, or redacted samples. Do not send private vendor, bank, tax, payroll, or customer data.
