The Accounts Payable section (FAP-ACC-AP) is responsible for recording, controlling and authorizing all supplier invoices for payment. All invoices and credit notes from suppliers must therefore be sent directly to FAP-ACC-AP, preferably electronically.

The section collaborates closely with:

• The technical party
• The commercial party
• General Accounting
• The Treasury service
• Suppliers

The section treats between 45,000 and 50,000 invoices in a normal year.

If the controller detects differences when they are controlling an invoice, they make contact with the technical contact, the commercial contact or the supplier depending on the nature of the differences in order to find a solution.

Some orders require the “qualitative” approval of the Technical contact before the invoice can be paid in order to ensure the goods or services are conform to the order (these orders denoted as 'Manual' in the DAI).

The section is also responsible for all requests from suppliers related to invoices and payment. Using the email address accounts.payable@cern.ch via a ticketing system will ensure that the request is followed by the A/P service and assigned to the correct contact.
