Every claim traced back to your documents

GreenBook Ready doesn't give you a score and move on. Every criterion finding is cited to the specific page and paragraph in your business case. Every gap is identified with exactly what's missing.

  • Dual-agent search — semantic and keyword — cross-validated for accuracy
  • Confidence score per evidence match, not binary pass/fail
  • Specific remediation guidance for every partial or missing item
  • Chat with your documents to explore any finding in depth

business cases to Treasury

Official criteria, not interpretations

98 criteria mapped verbatim from HMT Green Book and supplementary guidance — not summarised, not inferred. The same criteria your approving authority will use.

Assess at any stage

OBC or FBC — the platform identifies which criteria are applicable to your stage and focuses assessment accordingly. No wasted effort on criteria that don't apply.

Built for government data

Azure UK South processing. No programme-sensitive data leaves UK jurisdiction. Designed for commercial-in-confidence business case content from day one.

Submit with confidence,
not uncertainty.

A demo takes 30 minutes. We'll run an assessment against a business case from your sector — so you see what the platform finds, not just how it looks.
