The Invoice/Credit Note documents uploaded to the Portal can be in:
- PDF Format
- UBL 2.1 minimal format
- UBL 2.1 complete format
Only PDF format is accepted when sending invoices by email.
As part of an audit trail or PDF relationship with your client, the filed PDF must not be a scanned document but produced directly from your billing or office tool. If not, your PDF will be rejected with the reason "Document not eligible".
If the format of your document does not comply, you will be notified on the portal and by email
If the e-invoicing mode is "PDF signed", the PDF uploaded on SY must respect the following constraints:
- Not be protected against the signature.
- Comply with the ISO 32000-1 standard (PDF document format).
- If the PDF is already signed, the signature area must be complete.
- If the PDF is already signed, the certificate used must not be a self-signed certificate
