ROI & Business Case Building
Build a defensible business case the CFO will sign — not a slide of round-number savings — using a repeatable ROI model and sourced inputs.
A is the document that lets the buyer's say yes without doing the math themselves. It earns its right to be read by being conservative, sourced, and tied to outcomes the buyer already believes in. Loose claims are worse than no ROI claims — they signal that the seller has not been in a real CFO conversation.
The model below is the structure used inside enterprise deal desks: define the baseline, quantify the gap, model the intervention, net out the investment, and show against the cost doing nothing.
Deep practical explanation
Baseline — the cost the status quo, in dollars or hours, sourced to the customer's own data. If the buyer cannot point at the source, the is decoration.
Gap — the realistically improvable portion, not the theoretical maximum. CFOs discount any claim above 30–40% improvement on a mature process unless there is precedent.
Intervention — explicit mapping from capability to outcome. 'Faster reporting' is not an intervention. 'Replacing the manual reconciliation step in the month-end close, freeing 2 FTEs and reducing close from 9 to 5 days' is.
Investment — all-in over the analysis horizon: license, implementation services, internal labor, integration, training, , and ongoing operations.
Net benefit and — annualized benefit minus annualized investment, expressed as both percentage and . The payback is what the actually remembers.
Real-world example
A customer evaluated a workflow platform to replace three legacy tools used by their analytics team.
- Baseline: 14 analysts × 9 hours/week on data prep = 6,552 hours/year × $95 fully-loaded = $623k/year, sourced from the head analytics' own time-tracking sample.
- Gap: a credible 55% reduction (vendor's median for similar deployments) = $343k/year recoverable.
- Intervention: replace three manual data prep workflows; analyst time redirected to two named revenue projects with combined $1.4M expected lift.
- Investment (3-yr ): $260k license + $120k services + $60k internal = $440k.
- Year-1 : 12.6 months. 3-yr : 134%.
The slide that won the deal was not the percentage — it was a single line: 'At conservative inputs, you pay back the investment before the renewal.'
Tactical steps
- Co-build the baseline with the , using their data, in a working session.
- Anchor every assumption to a named source (their analyst, their report, a peer logo).
- Run two scenarios: conservative and expected. Never present 'aggressive' to a .
- Net out internal cost, not just license — CFOs disqualify proposals that ignore implementation labor.
- Pre-read the with the 48 hours before the meeting; let them sharpen it.
- Lead the meeting with , not percentage. Payback is intuitive; ROI invites debate on the denominator.
# BUSINESS CASE — [Customer] / [Initiative] Prepared by: [AE + Champion] Reviewed: [date] Audience: [EB name + title] Decision needed by: [date] ## EXECUTIVE SUMMARY (3 lines) [Customer] can recover $[X]/yr by [intervention], at a [N]-month payback against an all-in 3-yr investment of $[Y]. The risk of doing nothing is [quantified consequence] over the same horizon. ## BASELINE — cost of the status quo - Source: [name + dataset] - Today's cost: $[X]/yr (units × rate, sourced) - Trend if unchanged: [+/- %] over [horizon] ## GAP — realistic improvement - Improvable share: [%], based on [precedent / vendor median] - Recoverable benefit: $[X]/yr (conservative) | $[Y]/yr (expected) ## INTERVENTION — capability → outcome - [Capability] → [specific workflow change] → [measured outcome] - Owner inside [Customer]: [name] - Time-to-first-value: [N] weeks ## INVESTMENT — 3-yr TCO | Item | Yr 1 | Yr 2 | Yr 3 | 3-yr total | | License | $[...] | $[...] | $[...] | $[...] | | Services | $[...] | — | — | $[...] | | Internal labor | $[...] | $[...] | $[...] | $[...] | | Integration & infra | $[...] | $[...] | $[...] | $[...] | | Total | $[...] | $[...] | $[...] | $[Y] | ## NET BENEFIT & PAYBACK - Year-1 net benefit: $[...] - Payback period: [N] months - 3-yr ROI: [%] - Sensitivity: at -25% benefit, payback is still [N] months ## RISKS & MITIGATIONS 1. [risk] → [mitigation] 2. [risk] → [mitigation] ## ASK [Specific decision] by [date], so go-live aligns to [compelling event].
