One account.
Every client a receptionist.
Relay connects your Retell AI account to your clients’ booking systems. Describe a business in plain text, click build, and the receptionist is live — taking calls and booking appointments. You never open the Retell dashboard.
Create a project
One per client. Name it and you're in.
Connect their booking system
Square or Google Calendar, one click via OAuth.
Describe the business
A few plain sentences — hours, services, what callers ask.
Build
Relay writes the prompt, creates the Retell agent, functions, and webhook.
Books on the real calendar
Checks availability and books, cancels, and reschedules straight into the client's system.
Zero manual Retell work
The LLM, agent, custom functions, voice, language, and ambient sound are all built for you.
Per-client billing
Minutes, calls, and cost per month, with a flat or flat-plus-per-minute rate to charge clients.
One shared webhook
Every agent routes through one endpoint, told apart by a per-project secret — never a separate URL.
