FAQ
Common questions
Is this really free?
Yes. Unlimited validations, no account, no trial period. We charge for API access (developers) and Evidence Pack exports (enterprises). The validator itself is free forever.
Will auto-fix change my invoice amounts?
Never. Auto-fix only touches structural issues — formatting, namespaces, missing non-financial fields. Amounts, tax figures, bank details, and dates are never modified. That's a hard rule.
Do you store my invoice?
No. Invoices are processed in memory and deleted immediately after validation. We never store your financial data. Shared result links expire after 7 days and never contain the original XML.
Which EU countries require e-invoicing?
Italy, Belgium, and Romania already have live mandates. Germany, France, Spain, and Poland have upcoming deadlines between 2026–2027. Check our country guides for your specific situation.
Can I integrate this into my accounting software?
Yes. The Developer API validates and fixes invoices programmatically. Works with any ERP, accounting system, or workflow that can make HTTP requests.
