Retell minutes, billed to their card
Projection, not a forecast of a client’s usage. The client pays Retell directly, on their own card, for connected time only. This is not in the margin above. Every 1,000 minutes is $110–$125 at $0.11–$0.13 per minute.
Batch dialing adds $0.005 per dial. Add $0.015 per minute if Retell supplies the line. The full range is $0.07–$0.31 per minute depending on the voice and AI model.
From signed client to booked meetings
Two goals on every call: reach the decision maker and book a follow-up, or get the decision maker’s direct email from the front desk.
- 1
Client signs
Proposal approved. Monthly management fee billed through Stripe.
- 2
Build the list
Target niche and area. Up to 3 possible decision-maker emails per location (est. 75–80% found).
- 3
Build the brain
Scripts, voice, and every scenario mapped. AI disclosure where a state requires it.
- 4
AI calls
The Retell voice agent (same setup as Becky) works the list in batches.
- 5
Email follow-up
Sent from a separate look-alike domain. Phone and email together: 7–10 touches.
- 6
Meetings booked
Follow-up calls land on the client’s calendar.
- 7
Report + tune
Spot-check calls, fix weak spots (for example hang-ups at about 15s), report to the client.
Decision maker answers
Gives the pitch and works to book a follow-up call for the client.
Front desk answers
Asks for the decision maker’s direct email, or confirms the one on file. “Send me info” gets the receptionist’s email.
Voicemail / no answer
Tagged and called again at a different time of day. In the Denton test, 21 of 30 calls went to voicemail.
What only you do, and the team lanes
The team handles the daily work. These are the calls and approvals that need you.
You, Mike
- Sell it. Discovery calls, set the final price between $1,800 and $2,100, approve the proposal.
- Set the terms. Overages, territory pricing, and how minutes reach the client’s card.
- Approve the brain. Target list rules, call script, voice, and the email sequence before launch.
- Compliance sign-off. OK each state’s AI-calling and disclosure rules before calls go out there.
- Kick off each client. Onboarding call, client card on Retell, calendar access for booked meetings.
- Weekly review. Read the report, spot-check calls, approve tuning, check in with the client.
- Green-light the explainer. Verity holds the video until you say go.
The team & agents
- Sal writes the proposal and IO.
- Proton Bob keeps the service page and explainer page current.
- Emily writes the email sequence copy.
- ChaChing sets up and sends the monthly Stripe invoices.
- Ops / team builds and enriches the list, configures the Retell agent and number, re-queues voicemails, batches follow-ups, writes reports.
Open decisions waiting on you
- Overage terms aren’t set. The page defers them to the proposal.
- Territory pricing wasn’t answered on the call.
- Email/list tool hasn’t been picked. Instantly is used here only as a priced example.
- Billing setup: the client’s own Retell account, or rebill from yours?
- David’s proposal is due to Michael by the morning of Nov 13.
- “Calls at cost” wording is out. Say “minutes billed directly to your card.”
- Angle: chiropractor vs med spa (Michael says med spas run on a different model).
- What “seat” means to you. This dashboard assumes one more client account.
