## Frequently asked questions

### Can OCR output be used as an invoice without review?

No. Treat extracted values as a draft, then compare supplier, date, line items, currency, tax, and total against the original document.

### Should I use sales tax or VAT?

Use the calculation that matches the transaction's jurisdiction and tax basis. The workflow records the chosen calculation; it does not replace tax advice or rate verification.

### Why validate IBAN or VAT details before generating the PDF?

A polished document can still contain a costly identifier error. Validate the details before they are copied into a customer-facing or payable record.
