The hardest part of selling a voice AI agent is the first conversation. "AI" makes owners nervous. A demo with someone else's calls doesn't stick.
Their own missed calls do. You run their phone system, so you already know who misses the most. And before a customer switches the agent on, their portal shows them the same thing.
The short answer: pick the 20 customers who miss the most calls, show each one their own number, offer a month at your price, and launch them a few at a time. Twenty is enough to learn what sells and small enough to support well.
(Searchers call this an AI receptionist. We call it a voice AI agent, because it does more than answer.)

Why do missed calls sell it?
Because they're the customer's own, not a statistic.
- It's their number. "You missed 38 calls last month" is about their business, not the market.
- It has a time attached. Their portal names the busiest time of day and day of the week. The owner already knows who should have picked up.
- It prices itself. The owner weighs a month of the agent against one lost job or new patient. They do that math, not you.
What does a customer see before switching it on?
Their own missed calls, next to your offer.
When someone opens the agent in their portal before it's on, they see how many calls they missed in the last 30 days, from their own call records. Four tiles break it down: total missed calls, the highest missed-call rate, the busiest time of day and the busiest day of the week. Under it is an Activate button.
You write the rest. The headline, the description, the images and the prices shown are set in your partner portal. If you'd rather onboard customers yourself, turn the activation step off and they see a plain log-in button.
Which 20 customers should you start with?
The ones with the most to gain and the fewest surprises.
- The most missed calls. Pull them from the call records you already have. Sort by missed calls in the last 30 days.
- Calls worth money. Trades, clinics, law offices, property managers. One answered call pays for the month.
- Two or three industries, not ten. What you learn setting up one dental office carries to the next.
- Accounts that like you. Your first customers become your references and your case for the next 20.
Skip anyone mid-dispute, mid-migration or about to churn. Launch day is not the day to fix an old problem.
How do you reach them?
Three touches, each built on their own number.
- An email. Lead with the number, not the product: "Your main line missed 38 calls in the last 30 days, most of them after 5 pm. We can answer those for you." One link: a 15-minute call.
- A call. Walk through their missed calls together. Ask what one of those callers is worth.
- The portal. Ask them to open the agent in their own portal. The number is there, with your offer next to it.
Talk to the office manager. In the portal, only an Office Manager can switch the agent on. Basic users see the button greyed out, with a note to ask their office manager.
What should you offer?
A month, at your price.
- Quote a month, not a minute. "About $160 for a month like yours" lands better than "45 cents a minute." We suggest $45 to $95 a month plus $0.35 to $0.55 a minute. You set your own price.
- Make the first month easy to say yes to. A trial, a first-month credit, or a month-to-month start. Whatever fits how you bill.
- Show what they get. Calls answered after hours and when every line is busy, messages delivered while the caller is still on the line, and bookings if they use Cal.com.

How do you launch 20 without a support pile?
Five a week, not twenty at once.
- Batch them. Five customers a week gives your team time to read their first calls and fix what's wrong.
- Follow the first-week plan. Set up, test, go live on one answering rule, read every call, fix in drafts, then widen. It's all in the first 7 days.
- Watch it per customer. Your partner portal shows each customer's usage and billable amount, next to our wholesale cost.
How do you know it's working?
Their Insights tell them, in their own portal: calls handled end to end, transfers, and the reasons people called. Book a short review with each customer after their first month. Bring that page.
The customers who see their missed calls answered are the ones who tell other businesses about you.

FAQ
How do I find which customers miss the most calls?
From the call records you already keep for their phone system. Each customer also sees their own missed calls from the last 30 days in their portal, before they switch the agent on.
Can I change what the activation screen says?
Yes. You set the headline, the description, the images and the prices shown, in your partner portal. You can also turn the activation step off and onboard customers yourself.
Who can switch the agent on?
An Office Manager on the customer's domain. Basic users see the button greyed out and are asked to contact their office manager.
How many customers should I start with?
About 20, in batches of five a week. That's enough to learn what sells and few enough to read every customer's first calls.
What should I charge?
We suggest $45 to $95 a month plus $0.35 to $0.55 a minute. You set your own price. See how to price it.
