Commercial Business Case Guidance and Template Pack

1.     Guidance

How to complete the template, what “good” looks like, and common pitfalls to avoid.

This guidance supports the Spelthorne Commercial Strategy 2026/27 and ensures business cases are complete, compliant, proportionate and auditable. Use alongside the Business Case Template and the Author Checklist.

1. Proposal Overview

• Keep the summary short and outcome-focused.

• Be explicit about type of activity (e.g. procurement vs asset decision).

2. Strategic Alignment

• State which Corporate Plan priorities are supported and how residents benefit.

• Explain link to MTFS (e.g. savings, income, cost avoidance) and any IRP actions.

• Confirm statutory duties supported and any compliance risks mitigated.

3. Applying the Commercial Principles

• Purpose & Outcomes: define SMART benefits.

• Value for Money: present options with total cost, benefits and risks; include benchmarking or quotes where proportionate.

• Capacity & Capability: identify resource needs (skills, time, systems).

• Social Value & Local Impact: use the Social Value model relevant to SBC objectives; specify measurable commitments where possible.

• Insight & Innovation: summarise market engagement, research, or pilot learning.

• Transparency & Ethics: avoid off-contract purchasing; follow CPRs.

4. Commercial Lifecycle

• Always cover Identify→Assess→Plan→Procure→Manage→Review – scale your effort to the value/risk of the proposal.

• Include a simple options appraisal and sensitivity test for key cost drivers.

5. Governance & Assurance

• Costs: include lifecycle costs (set-up, operating, maintenance, exit).

• Risks: complete risk scoring; show mitigations and residual risk.

• Legal/Finance/Procurement: evidence input and approvals required before Committee.

• Technology & Data: engage IT/Data Protection early if systems or personal data are involved.

6. Documentation & Reporting

• Use standard templates; keep an audit trail of analysis, decisions and approvals.

• Store documents in the agreed location and reference them in the case.

7. Procurement & Contract Management

• Define outcome-based specifications; avoid overly prescriptive inputs unless necessary.

• Use evaluation criteria that balance quality and price appropriately.

• Set KPIs that are few, measurable and relevant; include change control, financial checks and exit arrangements.

8. Monitoring & KPIs

• Name the owner for each KPI, data source, frequency and governance route (e.g. quarterly committee report).

9. Transition Readiness (beyond 2027)

• Ensure assets, contracts and liabilities are recorded accurately and that handover documentation is complete.

Common Pitfalls & How to Avoid Them

• No options appraisal or weak VFM case → include at least a do-nothing and preferred option with cost/benefit comparison.

• Missing approvals or late engagement with specialists → involve Legal, Finance and Procurement early.

• Unclear KPIs → define measures before procurement, align to outcomes.

• Hidden costs → include overheads, lifecycle and exit costs.
