Pricing
Checking is free. You only pay for a finished file that passed the check — at download.
Questions
What is free?
Checking, the error report and the preview of the correction. The first verified download every 30 days is free. No account, no card.
What exactly do I pay for?
The finished file — built from your PDF or corrected —, only after the check passes, at download: €1.90 per file or €9 a month for all of them. Every paid file passes the KoSIT validator and comes with a public proof.
What if my file can't be corrected here?
Then you don't pay. You get the error report for your ERP support: rule, position in the file, expected structure.
Do you modify amounts?
Never. Amounts, line items, taxes and IBANs are blocked from modification by design. We only add missing mandatory details that you confirm yourself.
Do you store my invoice data?
Your file is used only to check and fix your invoice and to deliver your result. Results are kept so you can download a verified file again for 90 days; validation logs are deleted after 90 days. You can request deletion at any time.
How does the subscription work?
€9 a month, cancel monthly. Access via your email address, no password. Manage an existing subscription through the link in the footer.
