Current Crown Commercial Service suppliers: what you need to know

Guidance for suppliers who already supply goods or services to the public sector via the Crown Commercial Service (CCS).

Terms and conditions template

As a guide for suppliers and buyers there is a standard set of terms and conditions for framework agreements and call-off contracts for goods and services bought under the agreement. The template for call-off contracts forms the basis of the terms and conditions in individual further competitions and can be supplemented or refined with additional terms to suit the requirement.

Submitting monthly management information

All CCS suppliers must submit monthly management information (MI) returns. This is done online through the MISO system. You will need to include the unique reference number (URN) for each customer listed on the return.

Failure to submit MI returns correctly or within the agreed timescales may incur admin fees (MS Excel Spreadsheet, 12.1KB)

The customer URN list is made up of 4 tabs: live customer organisations, customers that have merged, customers that have changed their name and customers that are no longer active or eligible.

Please ensure you check this list before submitting requests for a new URN. All tabs within the customer URN list should be checked as some customer records may have been renamed or merged.

Promoting your place on a CCS agreement

Suppliers are encouraged to promote the fact that their goods and services are available through a CCS agreement to prospective public sector customers. To request a copy of the supplier marketing toolkit which includes logos and guidance please contact your CCS agreement manager or email

Supplier management

CCS manages suppliers on framework agreements. A network of Crown Representatives also helps ensure the government is getting the best value for taxpayers from its contracts with strategically important suppliers.

Audit and assurance

An annual supplier audit programme is carried out to provide assurance to the CCS board and the National Audit Office (NAO). The strategy is agreed in conjunction with the NAO and a risk based methodology is applied to identify suppliers to include in the annual audit plan.

This programme reviews:

  • the accuracy, appropriateness and completeness of management information returns
  • the timely and accurate payment of invoices
  • the appropriate and accurate charging of customers making purchases under framework agreements

As a CCS supplier, your organisation is also required to provide an annual self-audit certificate confirming that you have robust systems in place to identify, record and report accurate and complete framework spend.

Expiring agreements

When the CCS agreement you are on is expiring or being replaced you will need to retender for a place on the new agreement. Contracts are not renewed automatically.

Improving public procurement practice

CCS operates a Mystery Shopper scheme providing a direct route for suppliers to raise concerns about poor public procurement practice.
