Totals calculated

Omit line amounts, VAT breakdown and totals in your JSON — they are calculated with EN 16931 rounding.

No silent data loss

Conversions report every element the target format cannot carry.

Official validation

The KoSIT validator with the XRechnung 3.0, EN 16931 and Peppol BIS 3.0 rules runs next to the API.

Not stored

Documents are processed in memory in Azure West Europe and discarded after the response.
