ESS uses an electronic tendering system.

Visit ESS supplier portal

The system’s supplier portal is used for publishing information, sharing documentation, managing communications and receiving proposals from tenderers in connection with ESS procurement activities. Suppliers interested in ESS procurement activities can register and maintain a Business Profile in the supplier portal.

Regarding the European Commission Implementing Decision (EU) 2015/1478 of 19 August 2015 establishing the European Spallation Source as a European Research Infrastructure Consortium (European Spallation Source ERIC), and as adopted by the Council of the European Spallation Source ERIC, the European Spallation Source ERIC Procurement Rules will govern procurement conducted by the Organisation.

The European Spallation Source ERIC Procurement Rules apply to all contracts for the provision of goods, works and services, concluded in writing between ESS and third parties and financed by the ESS budget.  

The European Spallation Source ERIC Procurement team has prepared guidelines for our suppliers on our procurement process.

These guidelines are available to suppliers and potential suppliers to ESS to advise and provide clarity on aspects of the procurement process. The guidelines focus on practical issues related to implementation of European Spallation Source ERIC Procurement Rules. This document [ESS-0064113] may be updated from time-to-time.

Invoices sent to ESS must contain certain mandatory information. If the invoice is incomplete or incorrect, it will be rejected.
