## Summary

The National Audit Office (NAO), the UK’s independent public spending watchdog, procured an IT case management solution to support its financial audits across the United Kingdom. The solution is intended to help transform how the NAO conducts audits, with flexible workflows, robust content management, collaboration tools and data-led audit capability. It must also integrate seamlessly with the NAO’s existing systems. The requirement is for a technology solution and associated IT services, rather than general audit services. The NAO uses its audits to support Parliament in holding government to account and to help improve public services.

The procurement has been awarded, and the contract is active. Node 4 Limited, formerly Tisski Limited, was selected as supplier. The contract was signed on 1 March 2022, with a stated value of £8,926,458.12 and a period of 4,320 days. The process was for a single lot. The available information does not set out the procurement procedure or evaluation criteria. A contract amendment revised operational support arrangements for Apex, including service levels, fixed support charges and capped consumption-based services; it also changed or clarified performance measures and obligations, Microsoft responsibility, automated testing and supplier liability. The amendment was made to address risks identified through implementation and operation and to support service continuity; the overall nature of the contract remains unchanged.

For suppliers competing for a future NAO requirement of this kind, credibility will depend on delivering a flexible case management platform that can support dynamic financial-audit workflows, manage substantial audit content and enable effective collaboration. The solution must provide data-led audit capability and integrate reliably with existing NAO systems, so experience in complex enterprise implementations and systems integration would be directly relevant. The ongoing support arrangements matter as well: the contract’s amendment addressed service levels, fixed and consumption-based support charges, and continuity risks identified in operating the system. Suppliers should therefore be able to demonstrate dependable operational support and clear service management, alongside the technical capacity to maintain a business-critical platform. The requirement is UK-wide in reach and was awarded to a large supplier, indicating the scale of delivery and support expected.
