Retell AI is pay-as-you-go: $0 to start with 60 free minutes, then $0.07–$0.31 per minute of voice depending on the models and voices you choose. There are no platform fees and no per-seat licences, so cost scales with call volume rather than headcount.
What is the best AI tool for customer service?
The right tool depends on your channel mix. For phone-led support, a voice agent that resolves calls end to end matters more than a chat widget. Look for natural-language quality, live integrations with your CRM and helpdesk, a clean warm handoff to a human, and per-minute pricing that fits your volume.
