FAQ
What does the validator check?
It verifies required fields (invoice number, date, total, supplier), arithmetic consistency (subtotal + tax = total), VAT rate plausibility, and line item calculations (qty x price = line total).

PDF, JPEG, PNG, WebP, and GIF. Both scanned paper invoices and digital PDFs work. Maximum file size is 10 MB.
Is my invoice data stored?
No. Your invoice is processed in memory and immediately discarded. We do not store, log, or train on your documents.
How is the score calculated?
Each check earns points: passed checks get full points, warnings get half, and failures get zero. The score is the percentage of total possible points.
