Making the Business Case for GenAI
Quick answer
A strong GenAI business case counts hours saved after review, not drafting speed alone. Include setup, usage fees, review time, content upkeep and security. Add accuracy and brand voice risks. Then run a four-to-eight-week pilot on one task with a clear baseline. Measure quality and outcomes, not just speed.
Generative AI can draft proposals, summarize meetings, answer common questions and write product descriptions in seconds. Owners hear that and expect big savings. But a real business case also counts review time, usage costs and the risk of mistakes. That shows where it pays off.
Key Takeaways
- Generative AI saves time on drafting, summarizing and answering common questions.
- Count hours saved after review, not just drafting speed.
- Include setup, usage fees, review time, content upkeep and security.
- Accuracy and security risks belong in the case.
- Prove the numbers with a short pilot on one task.
- Measure quality and outcomes, not just speed.

Where it creates value
Drafting. Proposals, replies, descriptions and reports, as in event venue proposals.
Summarizing. Meetings, documents and long threads.
Answering questions. Support and internal help, as in SaaS GenAI.
More versions. Ad copy and content variations.
The broader view is covered in generative AI at work.
Count hours after review
Time today. Minutes or hours per task, by hand.
Time with AI. Drafting plus review and edits.
The real saving. The difference, not the drafting speed alone.
Full costs
Setup. Connecting your content and tools.
Usage fees. Per user or per request.
Review time. People checking every important output.
Content upkeep. Keeping sources current.
Security and training. Policies and staff guidance.
A worked example
This example uses assumed numbers. Replace them with yours.
Today. 40 proposals a month at 3 hours each is 120 hours.
With AI. If drafts save 1.5 hours each after review, that's 60 hours a month.
Value. At $40 an hour, about $2,400 a month before costs.
Subtract costs. Usage, setup spread over time and upkeep.
Quality and risk
Accuracy. Wrong facts cost more than they save, as covered in hallucinations.
Security. Data handling and hidden instructions, as covered in GenAI security.
Brand voice. Drafts that sound like you.
A pilot
One task. With clear volume and a baseline, mapped first as in discovery.
Four to eight weeks. Long enough to see patterns.
Fair comparison. As covered in off-the-shelf first.
A way to stop. As covered in AI pilots that fail safely.
A full plan. As in a 90-day GenAI roadmap.
How is the payback on generative AI calculated?
Monthly value minus monthly cost. The net gain.
Setup divided by net gain. Months to pay back.
Compare with other uses. As in the business case for predictive analytics.
What to measure
Time per task. Including review.
Edit rate. How much people change AI drafts.
Errors caught. Before work goes out.
Outcomes. Proposals won, questions resolved and hours returned.
Cost per task. Before and after.
The first three months
Days 1–30: choose and measure
Pick one high-volume task, time it today and list every cost of using generative AI for it.
Days 31–60: pilot
Run a four-to-eight-week pilot with review on every output, tracking time, edits and errors.
Days 61–90: decide
Calculate net value and payback, check quality and decide whether to expand, adjust or stop.
