A demo makes the buyer like the product; a business case makes them able to buy it. The case is how your champion sells your deal to everyone who wasn't in the room — the decision-maker who signs, the evaluators who judge it, the finance person who checks the math. If they can't defend the value, the deal stalls, no matter how good the demo was.
Build it from their numbers, not yours
The single rule of a defensible case: every number in it comes from the buyer. You don't invent ROI — you surface it. Walk through what the problem costs them today (the hours, the missed deals, the errors), what fixing it saves or earns, and how that compares to the price. Your champion will correct the numbers and, in doing so, take ownership of the case.
The structure that survives a committee
A case that holds up has three parts:
- Cost today. What is the problem costing them in money, time, and missed growth? Use their figures.
- Value of the fix. What changes when it's solved — and how does that beat the cost?
- Payback and urgency. How fast do they get their money back, and what does doing nothing cost while they wait?
Write it in one page, in their language, with their numbers. That page is what your champion hands to a procurement review or a vendor evaluation.
Where the case connects to everything else
The case is the through-line of the whole deal. It shapes the demo you run, it becomes the core of the proposal you write, and it's the anchor for the price you put on it. Value isn't a slide you tack on at the end — it's the argument the entire deal is built on.
Start here
Once you can quantify the value, the next skill is making sure you prove it to the people who matter — demoing to the decision-maker, the evaluator, and the champion, each in the language they'll defend.
