Convert a PDF invoice to UBL by recognizing the visible invoice data, reviewing that data and exporting it as structured UBL XML. SnelUBL accepts PDFs, creates UBL 2.1 or UBL 2.3, and validates the output before you download it or export it to SnelStart.
From PDF to UBL in four steps
- Upload the PDF. Use Quick Mode for individual files or a workflow for recurring invoices.
- Let the invoice process. A conversion takes about one minute on average.
- Review the data. Check and correct the supplier, customer, invoice number, date, lines, totals and VAT.
- Export the result. Export directly to SnelStart or download the UBL file for your accounting package.
SnelUBL provides UBL files for Exact Online, AFAS, Moneybird, e-Boekhouden.nl, Twinfield and Yuki. Follow the package provider's current import instructions.
Individual upload or automation?
| Situation | Suitable route |
|---|---|
| A few individual invoices | Quick Mode |
| Multiple files at once | Batch processing |
| Invoices arriving by email | Dedicated workflow inbox with automatic attachment detection |
| Invoices in a cloud folder | Dropbox, OneDrive/SharePoint or Google Drive |
| Connection from your own software | API |
The source PDF remains important as the readable document. UBL contains the structured fields for software processing. Always check that both documents belong to the same invoice and that their amounts match.
Price and free trial
The first 3 conversions are free and require no credit card. After that, SnelUBL costs EUR 0.35 per conversion, with no subscription or minimum. Usage is billed monthly in arrears.
