## How to read the results

- **Move the resolution rate.** Per-resolution products get more expensive as the agent gets better; per-conversation and per-session products do not. That is the most important difference between the models.
- **Seats are part of the price.** Where an agent only runs on the vendor's own helpdesk, the calculator adds that vendor's entry seat price for each human agent.
- **"Quote only" means we will not guess.** For vendors that publish no prices we show no number. Where procurement data exists, it is in the product's [pricing page](https://ai-agents.reviews/en-gb/pricing).
- **Use your own rate.** Vendor averages come from other companies. Run a [pilot](https://ai-agents.reviews/en-gb/guides/how-to-run-an-ai-agent-pilot) and come back with your number.

## What the calculator leaves out

Taxes, negotiated discounts, implementation services, voice minutes, add-ons, and overage penalties are not included. Prices are list prices in US dollars as published by each vendor on the verification date shown on this page. How billable units are defined differs by vendor; see [what counts as a resolution](https://ai-agents.reviews/en-gb/guides/what-counts-as-a-resolution).

## Frequently asked questions

### Why is there no price for some vendors?

They sell only by quote. We do not estimate a unit price we cannot source, and we do not use competitors' blog posts as evidence of another vendor's prices.

### Which resolution rate should I enter?

If you have not run a pilot, try 30%, 50% and 70% and look at how far the ranking moves. If it changes a lot, the pricing model matters more to you than the unit price.

> **Scored on a public rubric, from sources you can open.** Every score on this site comes from five published criteria: pricing transparency, performance evidence, access, coverage, and control. Each price and percentage comes from one product database and links to its source, so every page agrees with every other page.
