Per-resolution pricing punishes you for making the AI work
The billing model most of this category adopted has a structural flaw: the better your AI performs, the more you pay.
At $0.99 per resolution, an AI agent handling 10,000 tickets a month costs $9,900. In most markets that is more than the loaded cost of the support staff it replaced. That is the whole problem, and it is not a pricing tier issue — it is the model.
Software usually gets cheaper per unit of value as it works better. Per-resolution billing inverts that. Every ticket your agent successfully closes is a line item. Improve your help centre, tune your prompts, widen the agent's scope, and your bill rises in direct proportion to your success.
“It's structural: per-resolution pricing means every correct answer costs you, so you're financially punished for making Fin work well.”— r/CustomerSuccess
The break-even is lower than vendors imply
Rough arithmetic at $0.99 per resolution, ignoring seat costs, which you should not ignore:
| Monthly resolutions | Per-resolution cost | Verdict |
|---|---|---|
| 500 | $495 | Comfortably cheaper than a hire |
| 2,000 | $1,980 | Still reasonable |
| 5,000 | $4,950 | Approaching one loaded salary |
| 10,000 | $9,900 | Exceeds the staff it replaces in many markets |
Add Intercom seats underneath — one user reported a $74 monthly seat fee before any AI usage — and the crossover arrives earlier still. The model suits low and moderate volume. It works against you precisely at the scale where automation is supposed to pay off.
Nobody agrees what a resolution is
This is the part missing from every comparison article we found, and it decides your invoice more than the headline rate does. Vendors define a billable resolution differently. Some bill when the customer does not reply within a window. Some bill when the AI produces an answer at all. Some bill only on a positive signal from the customer.
A platform at $0.69 that bills on non-reply can cost more than one at $0.99 that bills on confirmed resolution. Ranking vendors by published rate is close to meaningless without this.
We are reading every vendor's billing definition from their own documentation and will publish them side by side. Until then this post does not characterise any individual vendor's definition second-hand.
What the complaints actually look like
This is not a theoretical objection raised by competitors. It comes from customers, repeatedly, in specific numbers. One r/SaaS thread with over seventy comments described billing rising 120% after enabling AI. An analysis of 215 Intercom reviews found the per-resolution charge described as a trap. A thread on r/customerexperience asking what teams pay drew thirty-five replies, one of which opened: we just got rid of Fin, cost way too much and did not work the way we needed.
The product is not the complaint. Nearly every critical thread concedes Fin works well before objecting to the price. That is an unusual pattern and worth noticing — it means the dissatisfaction is economic, not technical.
When per-resolution is the right choice
It genuinely is, sometimes. Under roughly 2,000 monthly resolutions the bill is predictable and clearly cheaper than headcount. If your volume is seasonal, paying only for what you use beats carrying seats through a quiet quarter. And the incentive alignment is real: a vendor paid per resolution has a reason to care whether resolutions happen.
Sierra argues this position publicly and consistently, and the argument has merit. It is simply not a universal one.
What to do before signing
- Model the invoice at your actual monthly volume, not the volume in the vendor's ROI calculator.
- Get the billable-resolution definition in writing before the trial ends.
- Ask what happens when a customer abandons mid-conversation. Billed or not billed?
- Model the same volume against a per-seat and a flat-rate competitor. If per-resolution loses at your scale, that is the answer.
- Check whether seat costs are required underneath. They usually are, and comparisons usually omit them.
None of this requires trusting us. It requires an hour with a spreadsheet and a direct question to a salesperson.

I run the testing here. Every platform on this site gets the same ticket set, the same escalation cases, and the same billing period — and I publish the invoice, not the marketing number. Where I have not tested something, the page says so.
