How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Intercom Essential (Per Seat) — Intercom Essential bills on a fixed plan from $39/mo, so the listed price is what you pay regardless of volume.
- Sierra (Per Usage) — Sierra bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.

Essential covers basic messaging; Advanced adds workflows and multi-brand; Expert adds SSO and audit logs.
Sierra is worth it if… Sierra is only worth engaging with if you're a mid-market or enterprise support org running a serious evaluation of autonomous AI agents — the co-founders' pedigree (Bret Taylor ex-Salesforce COO) opens doors that other startups can't. Deal size $200K-1M+/year.
