B2B e-invoicing through Peppol has been mandatory in Belgium since 1 January 2026. If your organization still receives supplier invoices as PDF, DOCX, scans or photos, SnelUBL can convert those source files to UBL 2.1 or UBL 2.3 so you can review and process the data.
What does this mean in practice?
| Situation | Practical step |
|---|---|
| Your accounting package supports Peppol | Check the package's activation and delivery instructions |
| A supplier still sends a PDF | Ask about e-invoicing and avoid manual retyping in the meantime by converting the source to UBL |
| You receive a scan or photo | Convert the source file and review the recognized data |
| You process invoices for multiple clients | Separate clients with organizations, workflows and dedicated inboxes |
| You want to automate recurring submissions | Use a workflow inbox, cloud folder or API |
From source file to structured data
- Submit the PDF, DOCX, PNG, JPEG, HEIF/HEIC or WebP file.
- Choose UBL 2.1 or UBL 2.3 based on what the receiving system supports.
- Review and correct the invoice data.
- Export to SnelStart or download the UBL file for another supported package.
- Separately check the Peppol profile and delivery requirements that apply to the transaction.
SnelUBL does not claim that a basic conversion by itself satisfies all Belgian or Peppol rules. Use current instructions from your accounting package and seek professional advice when you need legal or tax certainty.
