How web conversion works
For How web conversion works, this sequence gives the practical order of work.
- Open the converter and choose XRechnung, ZUGFeRD, UBL, CII, or another available target.
- Upload the invoice. One source file can be up to 20 MB.
- Review extracted supplier, buyer, tax, total, payment, and line-item data.
- Correct uncertain fields, run conversion and validation, then download the result and report.
What you should check
Technical validation checks the generated file. It does not replace your commercial or tax review. Compare important values with the source before sending the invoice.
When this route fits
Use the web route for occasional invoices and work that needs a visible review step. For repeated multi-file work, see the batch guide. For system integration, use the API guide.
