If you are a CSUC supplier, electronic invoices can be sent through e-FACT from AOC Consortium, the general point of entry of electronic invoices of the Catalan public sector.
For amounts of less than €5,000 (VAT excluded), these can be sent in PDF format via email to facturescsuc [dot] cat or via post to our corporate headquarters, unless these invoices are operations of successive or constant treatment.
Besides the legaly established requirements, invoices must include our VAT number (Q5856253I) and DIR3 code (A09019039), and an order number (Eaa/nn or Caa/nn) to allow us the proper processing of the invoice.
If you have any doubts on sending us an invoice:
