| Attribute | Intercom | Reply.io | Retell AI |
|---|---|---|---|
| Plans | Fin on its own $0.99 per outcome, monthly minimum Teams happy with their current helpdesk who want the AI agent only. | Email Volume From $49/user/mo billed yearly, or $59 monthly Email-only cold outreach. | Pay as you goOur pick About $0.07–$0.31/min Most small businesses and agencies. |
Essential $29/seat/mo, plus $0.99 per Fin outcome Small teams starting out with live chat and an AI agent. | MultichannelOur pick $89/user/mo billed yearly, or $99 monthly Teams running email and LinkedIn together. | Enterprise Custom High call volumes and compliance needs. | |
AdvancedOur pick $85/seat/mo, plus $0.99 per Fin outcome Growing support teams that need automation and several inboxes. | Jason AI SDR From $500/mo billed yearly Teams wanting AI to run outbound end to end. | ||
Expert $132/seat/mo, plus $0.99 per Fin outcome Larger teams with security and multi-brand needs. | |||
| 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. | Multichannel is the best value if you use LinkedIn at all, since the add-ons on Email Volume quickly cost more. Only look at Jason AI SDR once your manual sequences are already booking meetings. | Start on pay as you go with the free credits, build one agent for your most common call and test it on your own phone. Talk to sales only once you run thousands of minutes a month. |
