| Attribute | Intercom | Salesforce Agentforce | Sierra |
|---|---|---|---|
| Plans | Fin on its own $0.99 per outcome, monthly minimum Teams happy with their current helpdesk who want the AI agent only. | Salesforce Foundations Free Existing Salesforce customers who want to try agents. | EnterpriseOur pick Custom Large companies with high conversation volumes. |
Essential $29/seat/mo, plus $0.99 per Fin outcome Small teams starting out with live chat and an AI agent. | Flex CreditsOur pick $500 per 100,000 credits Businesses paying per action an agent takes. | ||
AdvancedOur pick $85/seat/mo, plus $0.99 per Fin outcome Growing support teams that need automation and several inboxes. | Conversations $2 per conversation Customer-facing agents where you want a simple per-chat price. | ||
Expert $132/seat/mo, plus $0.99 per Fin outcome Larger teams with security and multi-brand needs. | Agentforce add-ons From $125/user/mo Teams wanting AI help for every rep or agent seat. | ||
Agentforce 1 editions From $550/user/mo Large Salesforce customers buying the full bundle. | |||
| Which plan to pick | Start the 14-day trial and see how many conversations Fin handles, because that number drives the bill more than seats do. Most teams with more than a couple of agents end up on Advanced for the workflows. If you already run Zendesk or Salesforce and like it, try Fin on its own first. | Start with the free Foundations tier to prove one agent works, then move to Flex Credits so you pay only for what agents actually do. Per-user add-ons and Agentforce 1 editions are for large teams that have already proven the value. | There is one route: talk to Sierra's sales team. Agree clearly what counts as an outcome you pay for, and what setup and services cost, before you sign. |
