Quick answer: Per-response pricing charges you for the number of answers that arrive. For a trainer or consultant, that means the bill grows with attendance โ the one variable you cannot control and the one that should never be the reason you skip a report. Meter the deliverable, not the collection: answers should be free to receive, and you should pay only when a scored report is generated.
What the Meter Actually Charges For
Most form tools bundle a fixed number of responses into each tier, then move you up a plan when volume grows. The pricing page will say "100 responses per month" or "1,000 responses per month" โ the unit being sold is submissions. Nothing about that unit maps to the value you deliver. A workshop of 12 people and a workshop of 40 produce the same artifact for your client: a set of reports and one cohort view. The meter, however, treats them as two different products.
Four Behaviours a Response Meter Teaches You
- Cap your own reach. People shorten assessments, cut the follow-up round, or skip pre-testing because another batch of answers would push them into a higher plan.
- Split instead of scale. Two smaller forms replace one well-designed instrument, which quietly destroys comparability between cohorts.
- Pay for junk. Spam, duplicates and drive-off submissions still count against the allowance in many of these plans.
- Discover it late. The cap shows up mid-engagement: the form goes private or stops accepting answers during collection week, when restarting is impossible.
None of these are product decisions you would make on purpose. They are the meter's decisions leaking into your methodology.
Meter the Deliverable Instead
There is a second way to price this work: let collection be free and unlimited, and meter only the step that consumes real resources โ generating a personalized report. On FormLM that is how credits work. Collecting responses costs nothing and has no volume ceiling on any plan, including Free. Building an assessment takes roughly 10โ20 credits; each AI-filled report takes roughly 7โ20, because a report is where the model does work. A 30-person workshop lands around 220โ620 credits, which fits inside one Plus month; the third workshop in the same month is one $30 top-up, and credits never expire.
The important property is that the cost curve matches the value curve: more respondents means more reports, and reports are what the client receives. Your bill moves when your delivery moves, not when your attendance does.
What Happens at Zero Credits
Nothing breaks. Credits are capped bookkeeping, not a gate on the room: when a balance reaches zero the deduction stops at zero, forms keep accepting answers, and respondents still get their reports โ emailed when they left an address, on the result page when they didn't. You top up when it suits you. A pricing model that can embarrass you in front of 40 participants at 3pm is not a pricing model suited to facilitation.
Questions to Ask Any Vendor Before You Switch
- Which unit do you bill โ submissions, seats, or reports?
- What happens to a live form the hour it hits the cap?
- Does a duplicate or spam submission count against my allowance?
- Can I run a 40-person cohort without changing plans?
- If I export and leave, can I still get my historical responses out?
Today's numbers move; the shape of the meter does not. Read it before you build the engagement on top of it.
