# Austria e-Rechnung.gv.at (ebInterface 6.1)

Source: https://xmlvalid.com/schemas/at-erechnung-ebinterface-6.1

> An ebInterface 6.1 invoice to the Austrian federal government, checked against the schema and the checks e-Rechnung.gv.at makes before it accepts it.

Suppliers of the Austrian federal government (the Bund) send their invoices through e-Rechnung.gv.at, which rejects one that fails the schema or one of its checks and names the error by a code such as AF-0010 or EBI61-0012.
After the schema, the portal's checks run here with its codes: the order reference (an order number of ten digits starting with 47, a buyer group like Z01, or a buyer group and a reference) and the order position on each line, the supplier number, the biller's e-mail address, a delivery date or period, line, tax and invoice totals, discounts (Skonto), the payment method, the IBAN and up to 999 lines.

## Notes

- Rules run only when the document matches the schema.
- The checks are written by xmlvalid after the portal's published requirements, its error list and its own version of the ebInterface schema. Lookups in the federal accounting system (whether the supplier number and buyer group exist) and checks against the day of upload (an invoice date too old, a due date in the past) are not run, so a document gives the same result on any day.
- Amounts may be a cent off, and a period may end on the day it starts.
- The example is ours, with fictitious parties.
