Current system status: Live
The statutory requirements for contract and supplier reporting are introduced by the Defence Reform Act 2014 (the Act) and defined in the Single Source Contract Regulations 2014 (the Regulations). The Defence Contract Analysis and Reporting System (DefCARS, the system) is an online, web-enabled system which facilitates submission of statutory reports to the SSRO and MOD. When preparing reports, contractors must have regard to guidance issued by the SSRO.
Updates to the guidance applicable from 1 April 2024
The SSRO has updated its three guidance documents in support of its consultation on new and updated reporting guidance following the MODs changes to the legislation. The guidance documents can be accessed at the links below:
- reporting guidance on contract reports:
- reporting guidance on supplier reports:
- reporting guidance on DefCARS functionality:
There are updates to all three reporting guidance documents to reflect changes in the reporting requirements being introduced on 1 April 2024. We have reviewed the documents and, to make it easier for stakeholders to see the changes, we have also published track change versions of each guidance document.
We have made the following changes to the contract reporting guidance:
- explanation of how component level information can be provided;
- explanation of the information required where alternative pricing methods are used;
- explanation of the frequency of reporting depending on pricing approach;
- introduction of new data fields for new requirements; and
- removal of guidance no longer relevant.
The track change version of the contract reporting guidance is available here:
In the supplier report guidance, the following changes have been made:
- explanation of the change to the definition of a Financial Year to allow a period to be agreed with the Secretary of State;
- a new example scenario to support the above change; and

In the guidance on DefCARS functionality, the following changes have been made:

The track change version of the DefCARS functionality guidance is available here:
Notification templates for Qualifying Sub Contract (QSC) assessments
The guidance on aggregation principles included in the contract report guidance references notification templates which contractors can use once a QSC assessment has been undertaken. These templates are available on the SSRO Support page of the SSRO website.
Guidance on validation warnings in the system
DefCARS includes validation checks to help contractors comply with the reporting requirements and reduces the amount of data entry required by eliminating duplication. The SSRO has published a list of all the validation checks which are currently applied within the system and these were last updated on 25 March 2024 .
Qualifying Business Unit (QBU) templates
Copy and paste functionality is currently available in many parts of DefCARS. To allow contractors with QBUs to understand their reporting requirements and prepare their QBU Cost Analysis Reports (QBUCAR), a copy and paste template is provided: .
The Defined Pricing Structure (DPS)
Contractors or MOD staff who do not currently have access to DefCARS but wish to understand the DPS cost breakdowns, may access the DPS templates that preceded DefCARS. These previous templates are substantially the same as the current versions within DefCARS.
Analysis of DefCARS information
Under Section 36(3) of the Defence Reform Act, the SSRO must when requested to do so by the Secretary of State for Defence analyse reports provided to it under Section 24 or 25 and provide the results of the analysis to the Secretary of State or an authorised person. The SSRO has published details of example management information products which it supplies to the MOD:
