Order reference of the federal government

The order reference is a technical invoice address and for that an essential part of E-RECHNUNG.GV.AT. The order reference controls the mapping to the correct recipient and the processing of the submitted e-Invoice in the contracting authority system.

The order reference is solely issued by the contracting authority (E-RECHNUNG.GV.AT support as well as the USP hotline cannot give any information) and can be composed as follows:

  • 10 digit numerical value, e.g. 4700000001 (order number from the back-end system of the federal government)
    • In this case the order has to have at least one order position
    • An invoice line must always be linked to an order position
    • The order number automatically links the e-Invoice to the order and therefore assigns it to the contracting authority and a completely recorded invoice receipt is created
  • 10 digit numerical value with an additional buyer group (German abbreviation: EKG), e.g. 4700000001:Z01 (order number from the back-end system:buyer group). This version is mainly relevant for collective invoices (which are currently not supported by E-RECHNUNG.GV.AT).
    • In this case the order has to have at least one order position
    • An invoice line must always be linked to an order position
    • The order number automatically links the e-Invoice to the order and therefore assigns it to the contracting authority and a completely recorded invoice receipt is created
  • 3 digit alphanumerical value, e.g. Z01 (buyer group)
    • The buyer group is the smallest organisational financial unit in the back-end system
    • The invoice lines do not need to contain order position numbers
    • The buyer group automatically links the e-Invoice to the contracting authority and a partially recorded invoice receipt is created
  • 3 digit alphanumerical value with an additional internal reference, e.g. Z01:111599-0099-V-3-2099 (buyer group:internal reference)
    • The buyer group and the internal reference must be separated with a colon without a whitespace
    • The internal reference can be for instance a reference number, a contract number or an order number (though in this case the invoice is automatically linked to the order)
    • The invoice lines do not have to contain order position numbers
    • The buyer group automatically links the e-Invoice to the contracting authority
    • The internal reference serves the case worker of the contracting authority to link the e-Invoice to the order. It must not be longer than 50 characters.
