Analysis of Business Requirements for eInvoicing in a Public Procurement Context - March 2009 (EN)

The report "Analysis of Business Requirements for eInvoicing in a Public Procurement Context" is one of the deliverables of the IDABC eInvoicing & eOrdering pilot project and a joint initiative from the Directorate-General Internal Market and Services and the Directorate-General for Informatics of the European Commission.

This report contains the results of the business requirements gathering process for eInvoicing in a public procurement context, by collecting and analysing requirements from multiple sources:

  • Interviews with Member States having already implemented eInvoicing and eArchiving
  • Interviews with stakeholders, such as small, medium and large suppliers, solution (IT and financial) providers
  • Legal requirements for eInvoicing and eArchiving (mainly VAT) 
  • Other eInvoicing and standardisation initiatives
  • The results of the individual work packages are described in the final study, but the final result is the requirements catalogue.
