The agency pricing playbook for AI agents

We see a lot of agency pricing models — some thoughtful, some improvised. After working with a few hundred reseller partners, three structures stand out as durable. Here's when each one wins and what to expect from the math.

1. Flat retainer

A single monthly price per client, all inclusive. Easiest to sell, easiest to forecast, but absorbs all overage risk on your side. Best for verticals with predictable call volume — single- location dental, small law firms, niche e-commerce.

• Typical price: $400–$900/mo per location.
• Margin: 50–70% if call volume stays under 600 minutes.
• Risk: One unexpectedly busy month and you eat the overage.

2. Base + usage

A modest base ($150–$300) covers setup and seats, then per- minute or per-call usage rebills at your markup. Forces you to set markups carefully but protects you on volume swings.

• Typical structure: $200 base + $0.45/AI-minute (you pay $0.18).
• Margin: 55–65% across the book.
• Best for: Multi-location franchises, home services with peaks.

3. Outcome-based

You charge per appointment the agent books from incoming calls. Highest ceiling, hardest to sell, requires booking attribution that actually works.

Agencies that bill per booked appointment command the highest effective rates. They are also doing a lot of work to earn it.

Where the upsell lives

Month one is about proving the agent works. Month two is when margin actually grows — and the levers are predictable:

• Add website chat and WhatsApp for clients who get more messages than calls.
• Add appointment confirmations by SMS for booked visits.
• Add a dedicated business number per client.
• Charge for the white-labeled dashboard as “client portal.”

What kills margin

• Long onboarding calls — build vertical templates so a new client takes one hour, not eight.
• Tier-1 support burden — give clients direct dashboard access for the things they actually ask about (slot availability, transcript review).
• Custom one-off integrations — quote them, don't absorb them.

The mental model

Stop thinking of yourself as reselling minutes. You're selling a fully-managed answering service that never sleeps. The minutes are a line item; the outcome is the product. Price the outcome.
