Information to suppliers on electronic invoices (ZUGFeRD / XInvoice) / Replacement of incoming invoices in paper form

The e-invoicing requirement in public procurement is part of a Europe-wide standardization of electronic invoicing. The starting signal for this development was given in 2014 by Directive 2014/55/EU of the European Union. Germany has transposed the directive into national law with the E-Invoicing Act and the E-Invoicing Ordinance (ERechV). Since 27.11.2020, e-invoicing has been mandatory in public procurement. Please note in this context:

  • From a contract value / invoice value of € 1,000 (net), the UFZ is obliged to receive electronic invoices. You are welcome to provide us with your electronic invoices in ZUGFeRD format or XInvoice format. For each electronic invoice, one e-mail must be sent to the e-mail address .

  • Invoices under an order value of € 1,000 (net) can be sent to us either in the previously mentioned electronic formats or as a file in pdf format. Please understand that as of April 1, 2022, we will no longer be able to accept paper invoices and will return your paper invoices as of that date for our discharge.
  • The UFZ is not a direct agency of the federal administration and does not use the Central Invoice Receipt Platform of the Federal Government (ZRE). If you can only invoice/send your electronic invoices by using a routing identification number (routing ID), please use the Routing ID 993-80294-65.
