Frequently asked questions

Why was my Peppol invoice rejected?

Common causes include missing mandatory fields, invalid codes, malformed UBL structure, and inconsistent totals. Upload the XML to see the checks that RejectFix can identify.

Does RejectFix guarantee Access Point acceptance?

No. RejectFix performs its implemented diagnostic checks and safe repairs. It is not the official OpenPeppol Schematron and cannot guarantee acceptance.

Is my invoice stored?

Files are processed in memory for the diagnostic session. Do not upload documents containing information you are not authorized to process.
