Pricing

| Attribute | Gong | Intercom | Sierra |
|---|---|---|---|
| Plans | Platform fee Custom (billed yearly) Every Gong customer pays this, scaled to team size. | Fin on its own $0.99 per outcome, monthly minimum Teams happy with their current helpdesk who want the AI agent only. | EnterpriseOur pick Custom Large companies with high conversation volumes. |
Per-user licenceOur pick Custom per user (billed yearly) Each rep or manager who records and reviews calls. | Essential $29/seat/mo, plus $0.99 per Fin outcome Small teams starting out with live chat and an AI agent. | ||
Add-ons (Engage, Forecast, Enable) Custom Teams that want outreach, forecasting or coaching in Gong too. | AdvancedOur pick $85/seat/mo, plus $0.99 per Fin outcome Growing support teams that need automation and several inboxes. | ||
Expert $132/seat/mo, plus $0.99 per Fin outcome Larger teams with security and multi-brand needs. | |||
| Which plan to pick | Start with the core licence for reps who run customer calls and add Forecast or Engage only once the team uses Gong daily. Push back on bundles and multi-year terms during negotiation. | 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. | 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. |
