To whom should I send invoices?

One copy of invoice should be addressed to:

CERN
Finance and Administrative Processes Department
Accounts Payable / Bureau des factures (4-3-009)
CH – 1211 GENEVA 23
Switzerland

We would request that invoices are sent by post to the above address, or by email to accounts.payable@cern.ch .

Please do not send invoices with packages, they are received by another service. 

All invoices must mention the CERN order number(s) or CERN contract number under which the order was placed, along with the name of the technician who placed the order. These conditions are mandatory in order for invoices to be treated promptly.

Supplier bank account details – IBAN and SWIFT code or the complete bank account number – should also appear on invoices. Payment slips are not necessary.
