By 2026 every major support vendor prices AI on resolutions or conversations rather than seats alone. The rates are public and range from about $0.50 to $2.00. The definitions of what counts as billable did not standardise, which means two identical rates can produce very different invoices.
Key takeaways
- Outcome pricing won as a model. Definitional standards did not follow.
- The billable unit matters more than the rate in every usage model.
- Most vendors stack resolution charges on top of seat fees.
- Ask the same five billing questions of every vendor and compare the answers.
Two years ago, arguing for outcome-based support pricing meant explaining the concept. In 2026 it is the default. Zendesk, Intercom, Gorgias, HubSpot and Salesforce all charge for AI on something closer to outcomes than seats.
The model won. The definitions did not converge, and that is where the money is.
The state of play
Published rates as of September 2026, which you should verify on each vendor’s own page before budgeting:
- HubSpot Service Hub: $0.50 per resolved conversation
- Fidiora: $0.59 per genuine resolution, no seat fee
- Gorgias: around $0.90 to $1.00 per resolved ticket, $1.50 overage
- Intercom Fin: $0.99 per resolution
- Zendesk: $1.50 committed, $2.00 pay-as-you-go, on verified resolutions
- Salesforce Agentforce: $2.00 per conversation, or Flex Credits at $0.10 per action
Roughly four times between the ends. And with one exception, all of these sit on top of per-agent seat fees.
Why the spread is wider than it looks
Because the unit differs.
Conversation versus resolution. Salesforce prices per conversation. A conversation that ends without an answer bills the same as one that solved the problem. During an incident, when thousands of people ask when a broken thing will be fixed, that distinction is the entire invoice.
Verified versus self-reported. Zendesk now bills on verified resolutions, confirmed by an evaluation step rather than by the model that produced the answer. A stricter definition at a higher rate can be better value than a loose definition at a lower one.
Session versus resolution. Freshdesk meters AI Agent usage in sessions, with the first 500 included and roughly $49 per 100 after. A session is not a resolution, and if inactivity resets a session, one customer’s afternoon can be several billable units.
Action versus conversation. Salesforce’s Flex Credits bill per action at about $0.10 each. Twenty actions equals a $2.00 conversation, so the better model depends entirely on how many steps your agent takes.
Four different units. One category. No standard.
The seat fee nobody subtracts
The second reason rate comparison misleads: most of these are additive.
If a vendor charges $29 per seat and $0.99 per resolution, and another charges nothing per seat and $1.50 per resolution, the cheaper one depends on your ratio of people to volume. At twenty agents and low volume the first wins easily. At four agents and high volume the second does.
There is only one way through this and it is arithmetic. Total cost, including every line, divided by issues genuinely resolved. We published the full rate comparison with the seat fees stacked and the cost per resolution model.
The five questions
Ask every vendor, in writing, and put the answers side by side:
- Who decides a resolution succeeded, the answering model or something independent?
- Does an abandoned conversation count as billable?
- Is a conversation handed to a human billed?
- Does a reopened conversation retract the charge?
- Is there a hard spend cap I control, and what happens when I hit it?
That last one has become more pointed. Zendesk introduced automatic overage billing in January 2026 for teams exceeding committed volume, and Gorgias publishes a separate higher overage rate. Committed-volume discounts become penalties exactly when demand spikes.
What good looks like
An honest outcome model has four properties: a published rate rather than a quote, a published definition that excludes abandonment and handoffs, independent verification rather than self-grading, and a hard ceiling you set.
Not many vendors have all four. Zendesk moving to verified resolutions is genuine progress on the third. Published pricing remains uncommon at the enterprise end, where quoted agreements are still the norm.
Fidiora has all four, which is easy for us to say and easy for you to check: the rate is on the pricing page, the definition is at how we define a resolution, handoffs and abandonment are never billed, and the spend cap is yours to set. The machine-readable version is at /pricing.md.
The argument we would make regardless of vendor: outcome pricing only delivers what it promises when the outcome is defined by someone other than the party being paid for it.
