Financial case

Questions decision-makers ask
Straight answers.
How does BCG work?+
BCG guides users through HM Treasury’s Five Case Model step by step. Upload project documents, use BCG to generate structured draft content, refine it using Ask BCG, approve each section and export a compliant business case to Word and Excel.
Who is BCG for?+
BCG is designed for public-sector bodies and arm’s-length bodies; research organisations; NHS bodies; not-for-profits and charities; and private-sector organisations that use the Five Case Model as a robust approach to investment appraisal.
BCG vs generic AI tools?+
Unlike generic AI assistants such as Copilot, BCG combines decades of business-case expertise with purpose-built AI. It embeds Five Case Model structure, Green Book logic, traceable evidence and human approval rather than simply generating prose.
How fast can I produce a business case?+
Business cases that would normally take weeks or months can be developed in days—or, for some stages, hours—with AI-powered drafting, structured workflows and compliance support.
How does BCG ensure compliance?+
BCG is aligned with HM Treasury’s Five Case Model and Green Book guidance. Built-in structure and guardrails support consistent, high-quality outputs, while users retain responsibility for reviewing and approving every section.
Does BCG meet security requirements?+
Yes. BCG is hosted in UK AWS regions, is UK and EU GDPR-compliant, uses encryption and is aligned with the NCSC Cloud Security Principles. Customer data is not shared with third parties or used to train AI models. Security compliance information is available on request.
How do I get started?+
Request a focused 20-minute demonstration using the contact form. We will tailor the conversation to your organisation, business-case stage and timescale. Onboarding includes training and support tailored to your organisation.
How is BCG priced?+
Pricing reflects the number of licences, expected scale of use and the training or consultancy support required. We will recommend the most proportionate option after a short discovery call rather than forcing organisations into a generic package.
Can we run a pilot before wider adoption?+
Yes. A guided pilot can test BCG on a suitable live case, establish the time and resource savings, and give users practical experience before a wider rollout.
What support is included?+
BCG onboarding can include user training, facilitated working sessions and access to experienced business-case practitioners. The level of support is agreed around your team’s capability and the complexity of the case.
What outputs can BCG produce?+
BCG produces structured Five Case Model content, option appraisals, cost and benefit tables and value-for-money conclusions. Approved content can be exported to Word and Excel for review and assurance.
How does procurement work?+
We can provide the information public-sector procurement, information-governance and security teams need to assess BCG. Use the demonstration request form and add any specific procurement or security questions in the optional details field.
