How RejectFix works
RejectFix helps you investigate a rejected UBL invoice and identify safe, deterministic repairs.
1. Upload
Upload a UBL 2.1 XML invoice up to 5 MB. The file is parsed for the diagnostic session.
2. Diagnose
Our implemented checks look for missing fields, invalid codes, electronic-address problems, calculation inconsistencies and selected formatting issues. Each finding includes a rule ID and XML path.
3. Review the diff
When a safe repair is available, the preview shows exactly which XML lines would change. Repairs are deterministic; the system does not invent business values.
4. Export
If all remaining blocking findings are resolved by the safe repair pass, the repaired XML can be unlocked through the payment flow. Files that still contain unresolved blocking findings remain unavailable for paid export.
Privacy note
Invoice content is handled for the diagnostic session only. Upload only files you are authorized to process.
