Why does Willingness to Pay matter?
Nearly every early revenue model rests on a price nobody has ever paid, and that single unverified number propagates into market sizing, unit economics, and the fundraising deck. Asking about price directly is famously unreliable, people underestimate what they would pay for something they need and overestimate what they would pay to be agreeable. The only trustworthy evidence is behavior: a signed order, a deposit, a card on file.
What does Willingness to Pay look like in practice?
"What would you pay for this?" produces a number that means little. "You mentioned losing about four bookings a month, what is a booking worth to you?" produces an anchor grounded in their economics rather than your hopes. Stronger still: quote a real price and watch the reaction. A pre-order at a discount is worth more than fifty survey responses.
What are the common mistakes with Willingness to Pay?
- Asking directly and treating the answer as data.
- Anchoring on competitor pricing for a product doing a different job.
- Pricing off your costs rather than the value delivered.
- Never naming a price out loud until launch, which delays the most informative conversation you can have.
Where the term comes from
The four-question survey most founders eventually meet is older than SaaS. Dutch economist Peter van Westendorp introduced his Price Sensitivity Meter in 1976, asking at what price a product would seem too cheap to trust, a bargain, expensive but worth considering, and too expensive to buy. Plotting the four cumulative curves and reading their intersections is still the method.

- Painkiller vs. VitaminA painkiller solves a problem someone is actively suffering from; a vitamin offers an improvement they agree would be nice. Painkillers get bought, vitamins get postponed.
