Registration of a Team Account (Teams and Collaborations)

Applicable to:  Other persons concerned, Members of the personnel


A Team Account is a CERN budget code or cost centre used for keeping track of expenditure at CERN and its corresponding external funding.

Accounting entries are made on behalf of and for the benefit of the requesting Funding Agency or Collaboration. Transactions are not detailed in the CERN annual budget funded by Member State contributions.

Team Accounts should be used exclusively for professional activities in the framework of collaboration work in a CERN experiment executed on CERN's premises.

Research institutes actively participating in an experiment at CERN may request the opening of a Team Account either independently or in collaboration with other research teams.

For externally funded R&D projects at CERN, or other cases that do not clearly enter one of the below described cases, please refer to the External Contributions and Fundraising website.

N.B.: CERN has formulated and adopted official policies related to integrity and anti-fraud that bind all CERN employees and partners:

1.2 Request the opening of a Team Account

Visiting Research Team Account

The head of the funding agency or a responsible Finance Officer authorised to make financial commitments on behalf of the funding agency shall fill and sign an Application and update form for a visiting research Team Account.

More information about the role of Finance Officer can be found under Roles, responsibilities and access rights (Teams and Collaborations) (see paragraph 1.1). The Finance Officer of the Institute should not assign him or herself as Team Account Manager.

The form fields include pop-up help texts, visible when completing the form on a computer. Please fill out all fields.

The invoice address should be the official address to the Accounts Payable service of the institute or funding agency requesting the opening. If exceptionally a governmental body shall pay the invoices, this shall be justified in an enclosed letter. The responsibility of control and reporting still lies with the signing Funding Agency/Institute.

The signed form shall be sent electronically to or by paper to CERN, FAP-EF-TC, Mailbox C20700, CH-1211 Geneva 23.

Collaboration Team Account

In the case of a new Collaboration common fund Team Account, the written request shall come from the nominated Spokesperson or Resources Coordinator and be accompanied by the corresponding MoU. The opening of additional Team Accounts for the collaboration can be requested in writing by the collaboration’s Resources Coordinator or secretariat with the Spokesperson or Resources Coordinator in Cc.

Special Fund Team Account

A Special Fund Team Account can be requested by the CERN contact person mentioned in the agreement or by one of the signatories of the agreement.

A special Fund Team Account can be opened if the agreement clearly indicates that expenses and revenues shall be managed on a Team Account or if the agreement modalities defines a functioning which makes it more appropriate to manage the revenue and expenses on a Team Account rather than on a CERN code.

1.3 Approval of the request

If the request is approved, the nominated Team Account Manager will receive an e-mail giving access to the website for Team Account Management together with important information on how to financially manage and check the Team Account. The Team Account will be activated only after the Team Account Manager has entered and confirmed the accuracy of the registered information and assigned roles such as signature holders for the Team Account.
