Which plan to pickStart 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 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.
