Sierra vs Intercom Fin 2026: Outcome Pricing vs Per-Resolution

The headline: Fin gives you one published number to plan against ($0.99 per resolution), while Sierra ties price to defined business outcomes but does not publish the rate.^[2][1] Both are "you pay when it works" models, and both decline to charge for a bare handoff to a human. The difference that decides the choice is whether you can know your cost before signing. This article lays out the two pricing shapes and the economics they sit inside.

1. Outcome-based vs per-resolution

Intercom Fin charges $0.99 per outcome, counted when Fin resolves an issue end to end or completes a configured procedure, with a 50-outcome monthly minimum standalone and no platform fee against an external helpdesk.^[2] Bundled with Intercom's helpdesk, seats add $29 to $132 per seat per month.^[3]

Sierra uses outcome-based pricing: you pay only when an agent achieves a defined, valuable outcome such as a resolved support conversation, a saved cancellation, an upsell, or a cross-sell.^[1] Sierra does not publish a per-outcome dollar rate, and the definition of an outcome is set per contract. Any specific Sierra figure is not publicly documented as of May 2026.

2. The pricing comparison

Dimension	Sierra	Intercom Fin
Pricing model	Outcome-based[1]	Per resolution (outcome)[2]
Headline rate	Not publicly documented (as of May 2026)[1]	$0.99 per resolution[2]
Charge on escalation	No charge in most cases[1]	No (outcome only on resolve)[2]
Minimum / commitment	Per-contract, not public[1]	50 outcomes/month standalone[2]
Self-serve signup	No, sales-led[1]	Yes (14-day trial)[2]
Outcome scope	Broad (resolution, retention, upsell)[1]	Resolution / procedure completion[2]

The structural contrast: Fin defines one outcome type (a resolution) and prices it publicly, so you can model the bill. Sierra defines outcomes broadly across the customer lifecycle and prices them privately, so the bill follows business value but you cannot forecast it without a contract.

3. Cost predictability per resolved conversation

Fin's cost per resolved conversation is its headline rate: $0.99, plus a share of Intercom seats if you bundle the helpdesk.^[2][3] At 1,800 AI-resolved conversations a month (the resolved count in the scenario below), the Fin line is about $1,782 at $0.99 each. That number drops straight into a forecast.

Sierra's cost per resolved conversation cannot be stated from public sources, because the rate is private and the outcome definition varies by contract. The honest framing: not publicly documented (as of May 2026). What is documented is the model's shape, you pay on outcomes, which can include more than resolutions, so Sierra's per-conversation cost depends heavily on how broadly outcomes are scoped in your agreement.^[1]

4. The escalation difference that matters

Both models share one buyer-friendly property: a plain escalation to a human is not billed. Sierra states there is no charge in most cases when a case escalates, and Fin counts an outcome only when it resolves or completes a procedure, so a handoff alone costs nothing.^[1][2]

This is the right alignment for support automation: you pay for resolved work, not for the tool trying and failing. It also means the effective cost per ticket depends on the resolution rate. If the agent resolves 60% of tickets, you pay the per-outcome rate on that 60% and nothing on the 40% it escalates. The lower the resolution rate, the lower the bill, but also the more human time you still spend on escalations.

5. The human baseline both replace

Both tools are sold against human-agent cost. The engine below prices a 3,000-ticket-per-month operation at a 60% resolution rate, inside the 55-70% tier-1 AI resolution band industry benchmarks report for 2026. The engine's AI-cost figure is a model token-and-escalation cost, not a vendor invoice; treat Fin's $0.99 per resolution as the real vendor line, and the engine as the human-vs-AI economics around it.

At this volume the human-only cost is $17,600 a month, and an AI-first setup resolving 60% of tickets cuts it roughly in half while escalating 1,200 tickets to humans. Whichever vendor fills the AI line, the gap between human-only and AI-first is the prize. The vendor question is which pricing model makes that gap predictable.

6. Which model fits you

1. Solo founder or small team: Intercom Fin. The $0.99 per-resolution rate is published, self-serve, and budgetable, with no platform fee standalone.^[2]
2. Enterprise wanting price tied to business value: Sierra. Outcome-based pricing across the customer lifecycle aligns spend with results, but expect a sales process and a contract-defined rate rather than a public number.^[1]
3. You want to pay only for resolved work: both qualify. Neither bills a bare escalation, so the choice comes down to transparency (Fin) versus outcome breadth (Sierra).

Frequently asked questions

What is the difference between Sierra and Intercom Fin pricing?

Intercom Fin charges a published $0.99 per resolution (outcome) with a 50-outcome monthly minimum standalone. Sierra uses outcome-based pricing where you pay only when an agent achieves a defined business outcome such as a resolved conversation, a saved cancellation, or an upsell, but Sierra does not publish a per-resolution dollar rate, so a specific Sierra number is not publicly documented as of May 2026 (verified May 2026).

Does Sierra charge when a case is escalated to a human?

No. Sierra's outcome-based model states that in most cases there is no charge when a case is escalated, because you pay for completed outcomes rather than attempts. Intercom Fin similarly counts an outcome only when Fin resolves the issue or completes a configured procedure, so neither charges for a plain handoff (verified May 2026).

Which is more predictable, Sierra or Intercom Fin?

Intercom Fin is the more predictable of the two for a small team because its $0.99 per-resolution rate is published and self-serve. Sierra's outcomes are defined per contract and the rate is not public, so cost predictability depends on how outcomes are scoped in your agreement. For a solo founder who needs to forecast the bill before signing, Fin is the budgetable option.
