Executive Business Case Builder for Renewal & Expansion
A structured fill-in template that turns usage data, cost savings, and outcome metrics into a one-page CFO-ready financial justification for renewing or expanding — written in the language of a finance team, not a sales deck. Includes ROI formulas, cost-of-inaction calculation, risk-adjusted payback period, and a stakeholder sign-off tracker.
What's inside
- Quantified ROI section with GBP formulas and fill-in placeholders
- Cost-of-inaction (COI) calculator covering hard costs, soft costs, and risk exposure
- Risk-adjusted payback period formula with a conservative-case modifier
- Named-stakeholder sign-off tracker with role, decision type, and status fields
- Honest "numbers don't stack up" diagnostic with three alternative paths
- Renewal vs. expansion variant guidance so the same template covers both scenarios
- One-page summary layout designed to survive a 90-second CFO skim
- Failure mode warnings flagged inline so you know where cases typically fall apart
Who this is for: Account managers preparing for a renewal or expansion conversation with an economic buyer — typically a CFO, Finance Director, VP of Finance, or a budget-holding operational lead.
What this is not: A slide deck, a feature list, or a value story. This is a financial document. Fill it in with real numbers or don't send it.
Before You Start: Minimum Data Required
Do not begin without these. Guessing weakens the case and damages your credibility with finance teams.
| Data point | Where to get it |
|---|---|
| Customer's contract value (current) | Your CRM or contract |
| Proposed renewal / expansion price | Your pricing sheet |
| Measurable outcomes the customer has achieved | QBR notes, support tickets, CSM records |
| Customer's internal cost baseline (pre-solution) | Discovery notes or a direct ask |
| Usage data (seats, volume, frequency) | Your platform analytics |
| Any competitor or alternative pricing the customer has mentioned | Call notes, renewal risk flags |
If you cannot populate at least four of the six rows above, do not attempt to build this case yet. Run a data-gathering call first.
Section 1: Account Summary
One sentence per field. This is context for a reader who doesn't know the account.
- Customer name:
- Contract start date / renewal date:
- Current annual contract value (ACV): £[current ACV]
- Proposed new ACV (renewal or expansion): £[proposed ACV]
- Incremental spend being justified: £[proposed ACV − current ACV] (for renewal, this may be £0 increase — you are justifying continuation)
- Business case prepared by / date:
Section 2: Quantified ROI
The formula:
ROI % = ((Total Quantified Benefit − Annual Solution Cost) ÷ Annual Solution Cost) × 100
Work through the table below. Include only benefits you can back with a number. Leave rows blank rather than invent figures.
| Benefit category | How to quantify it | £ value (annual) |
|---|---|---|
| Time saved (hours × fully loaded hourly cost) | [Hours saved per week] × 52 × £[hourly cost] | £ |
| Error or rework reduction | [Number of incidents reduced] × £[average cost per incident] | £ |
| Revenue directly attributable to the solution | [Deals closed / retained / accelerated] × £[average deal value] × [attribution %] | £ |
| Headcount avoided or redeployed | [FTE not hired or redeployed] × £[loaded annual cost per FTE] | £ |
| Cost of previous/alternative solution removed | £[previous vendor or manual process cost] | £ |
| Penalty or compliance risk avoided | £[fine / liability exposure] × [probability without solution] | £ |
| Total quantified benefit (A) | £ | |
| Annual solution cost (B) | £[proposed ACV] | |
| Net benefit (A − B) | £ | |
| ROI % ((A−B) ÷ B × 100) | % |
Payback period (months) = B ÷ (A ÷ 12)
= £[proposed ACV] ÷ (£[total benefit] ÷ 12) = [X] months
Risk-adjusted payback period: Multiply the raw payback period by 1.25 to account for adoption lag and partial realisation. If this number exceeds 18 months, see Section 5 before proceeding.
Risk-adjusted payback = [X months] × 1.25 = [Y months]
Section 3: Cost of Inaction (COI)
This is the section economic buyers read most carefully. It answers: what does doing nothing actually cost?
Calculate over a 12-month period. Be conservative — finance teams will probe inflated numbers.
| Inaction scenario | Calculation | £ annual cost |
|---|---|---|
| Reverting to previous process / manual workaround | [Hours per week to operate manually] × 52 × £[hourly cost] | £ |
| Re-procurement cost (time, resource, legal, onboarding) | [Internal hours] × £[loaded rate] + £[external fees] | £ |
| Lost productivity during transition / gap period | [Weeks of reduced output] × [team size] × £[weekly loaded cost per person] | £ |
| Performance degradation (revenue at risk) | £[revenue currently dependent on solution] × [% risk of loss] | £ |
| Competitive disadvantage (if quantifiable) | [Market share or deal volume at risk] × £[margin per unit] | £ |
| Total cost of inaction (12 months) | £ |
COI summary sentence (write this out in plain English — copy it verbatim into your email or presentation):
"Choosing not to renew carries an estimated cost of £[total COI] over the next 12 months when re-procurement, productivity loss, and [most material risk item] are accounted for. This compares to a renewal investment of £[proposed ACV]."
Section 4: Stakeholder Sign-Off Tracker
Track every person who needs to approve or influence this decision. Renewal and expansion deals fail most often because one stakeholder is unaware or unsupportive.
| Name | Role / title | Decision type | Current position | Next action | Owner | Due |
|---|---|---|---|---|---|---|
| Economic approver | ☐ Supportive ☐ Neutral ☐ Unknown ☐ Against | |||||
| Technical approver | ☐ Supportive ☐ Neutral ☐ Unknown ☐ Against | |||||
| End-user champion | ☐ Supportive ☐ Neutral ☐ Unknown ☐ Against | |||||
| Legal / procurement | ☐ Supportive ☐ Neutral ☐ Unknown ☐ Against | |||||
| Finance sign-off | ☐ Supportive ☐ Neutral ☐ Unknown ☐ Against |
Flag: Any stakeholder marked "Against" or "Unknown" with fewer than 30 days to renewal must be addressed before this business case is submitted. Submitting a document over an unresolved objection accelerates a no.
Section 5: When the Numbers Don't Stack Up
Do not bluff. If the ROI is weak, the payback period is long, or you cannot populate the benefit rows with real figures, you have three options:
Option A — Delay the case, not the conversation. Go back to the customer and run a structured value audit. Ask: "Where have you measured the impact of [solution] this year?" You may be missing data that exists. Do this at least 60 days before renewal.
Option B — Reframe the case around risk, not return. If ROI is thin but COI is significant, lead with Section 3. "The case for staying isn't that we deliver a 4× return — it's that switching carries £[COI] in transition costs alone." This is an honest and defensible position.
Option C — Propose a right-sized renewal. If the expansion doesn't justify the uplift, say so and propose a flat or reduced renewal that does stack up. A smaller deal that closes is worth more than a full expansion that collapses at finance review — and it protects the long-term relationship.
What not to do: Do not submit a business case with estimated or illustrative figures dressed up as real ones. Finance teams identify this immediately. It ends deals and ends relationships.
One-Page Summary Layout
When presenting to an economic buyer, condense Sections 1–3 onto a single page in this order:
- Investment: £[current ACV] → £[proposed ACV] (or flat renewal at £[ACV])
- What it's delivering: [2–3 bullet outcomes with £ values from Section 2]
- Return: £[net benefit] annual benefit / [Y months] risk-adjusted payback / [ROI]%
- Cost of not acting: £[total COI] over 12 months
- Decision required by: [date] — see stakeholder tracker
Total reading time for a CFO: under 90 seconds. That is the target.
Renewal vs. Expansion: Which Variant Applies?
| Scenario | Primary emphasis | Key difference in framing |
|---|---|---|
| Flat renewal | Justify continuation / COI | Lead with COI and risk; ROI confirms the decision already made |
| Renewal with price increase | Justify incremental spend | ROI must cover the delta, not just the total ACV |
| Expansion (new seats, modules, scope) | Justify net-new investment | ROI and payback must be calculated on the expansion cost alone, not blended with existing ACV |
For expansion, run the ROI formula in Section 2 twice: once for the existing contract (proof it works) and once for the incremental investment only (proof the expansion pays back).
How to use it
Pull your account's usage reports, any outcome data the customer has shared, and your pricing before you start. Work through each section in order — the formulas carry forward, so completing them sequentially takes under 30 minutes. Present the completed one-pager to the economic buyer directly, or use it to coach your champion on how to make the internal case without you in the room.
