When to send it
Run this with current customers before you change prices, and again a couple of months after any change. Show it inside the product to people who have paid for at least a month or two, so everyone answering has weighed the price against real use. On Pro, a slide-in on your billing or plans screen reaches people while cost is on their mind; on any plan, an inline embed on the account page or a link in your help menu works.
Avoid running it straight after an outage or a billing mistake. The answers would measure the incident, not the price.
Why these questions
The first question asks how the price feels for what they get, with four plain options from "too expensive" to "a bargain". It doesn't ask what people earn, what their company turns over or what they pay for other tools. Perceived value is what decides renewals, and customers can answer it honestly in a few seconds.
Anyone who picks either of the expensive options sees a checklist of common reasons: they don't use enough of it, similar tools cost less, the jump between plans is too big, it's hard to justify to someone else, or money is tight right now. Each implies a different response. Underuse calls for better onboarding, not a lower price. A big jump between plans calls for a middle tier. Trouble justifying the cost calls for a one-page summary of your product's value that a customer can forward to whoever approves spending.
The plan clarity question uses agreement wording on a 1–7 scale. Confusing plan pages lose sales quietly, and this number tells you whether yours is part of the problem.
The billing question asks how they'd prefer to pay: flat monthly, yearly with a discount, by usage, or per person. Founders often guess this wrong, and switching models later is painful.
The survey closes with one open question about what they'd change.
Why there's no coupon
A discount inside a pricing survey muddies the very thing you're measuring. People who have just been handed money off are not a neutral audience on whether the price is fair.
What to do with the answers
If you share separate links with newer and longer-standing customers (each channel on the Share dialog gets its own link), compare the two groups. When new customers say "about right" and older ones say "too expensive", the product may not be keeping pace with what people expected when they signed up. Treat the reasons checklist as a to-do list ordered by count.
Don't change prices on one round of answers. Set them beside what you hear in cancellation reasons and trial ended surveys, where price comes up from people who actually walked away. If all three sources agree, act.
