This is an operational data signal tool—not accounting, tax, legal, collection, or compliance advice. Use a de-identified copy and keep your original file backed up.
Know what the result means
A fixed operational check—not a promise of correctness.
The checker reports deterministic signals from the columns you map. It cannot verify bank receipts, invoices, tax treatment, identity, fraud, disputes, or whether the underlying records are complete.
What it does not prove
- Accounting, tax, legal, or compliance accuracy
- Successful collection or future revenue
- Source-system completeness
- Currency conversion or reconciliation
- Compatibility with every CSV export
