How to Write an AI Business Case Your CFO Will Approve

TL;DR: Four parts: the problem (quantified in dollars), the solution (specific and scoped), the ROI (conservative and time-bound), and risk mitigation (pilot phase). Skip hype. Lead with numbers.

CFOs don't get excited about technology. They get excited about returns. Walk in with "digital transformation" and walk out empty-handed. Walk in with a clear problem, scoped solution, and conservative ROI — walk out with a green light.

## Step 1: Quantify the Problem

Make the problem expensive before you mention AI.

Example: Support team spends 3 hours/day on repetitive questions. - 3 hrs/day x 5 people = 15 hrs/day - 15 hrs x $35/hr = $525/day - $525 x 260 days = $136,500/year

Include hidden costs: opportunity cost, error rates, customer impact from slow response.

## Step 2: Propose a Specific Solution

Bad: "Implement AI across customer support." Good: "Deploy an AI email responder for Tier 1 tickets on Zendesk, handling 12 question categories representing 65% of volume."

Include: what AI does (and won't), systems involved, who's affected, timeline, total cost.

## Step 3: Conservative ROI

Estimate 50% workload handled (conservative). $68,250 in savings. Minus $15,000 implementation + $3,600/year subscriptions.

Year 1: $49,650 net. Payback: Under 3 months.

Add sensitivity analysis: what if results are 25% worse? If numbers still work, finance loves the margin of safety.

## Step 4: Risk Mitigation via Pilot

"One team, 30 days. Success: 40% reduction in Tier 1 handling time, 90%+ accuracy. If we hit it, we scale. If not, total exposure: $5,000."

$5,000 bet on a $65K/year saving = easy yes.

## One-Page Template

Problem: [Workflow] costs [$X]/year. Solution: Deploy [AI tool] for [function], integrated with [systems]. Investment: [$X] implementation + [$X]/month. Return: [$X] annual savings. [$X] payback period. Risk: 30-day pilot, [$X] total exposure, [criteria]. Ask: Approve [$X] for pilot by [date].

## FAQ

Q: CFO skeptical about AI? A: Don't sell AI. Sell the business outcome that uses AI.

Q: Hard-to-quantify benefits? A: Lead with time saved — easiest to measure, hardest to argue.

Q: Include competitive pressure? A: Yes, briefly. "Top 3 competitors deployed similar automation" — one powerful line.

Q: Pilot succeeds but scaling is expensive? A: Include scaling costs upfront. Show full picture.

Q: Pilot length? A: 30 days for simple, 60 for complex.

Q: Who presents? A: Person closest to the problem. Technical details from IT/AI partner. Operations leads, finance approves.

Q: Pilot metrics? A: Time saved, accuracy rate, adoption rate, one business outcome metric.
