| Which plan to pick | Growth is enough for a small team that just needs a tidy shared inbox with AI help. Choose Pro if you need response-time targets, CRM or Shopify data next to each email, or the API. Voice is an add-on at $30 per seat. | 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. |
