Your AI plan

When you reach your plan's usage limit, a run waits for the reset, then carries on. To raise the ceiling, move up a plan.

Hosting

Vercel, Cloudflare Pages and Netlify all have free tiers, and you can also put sites on your own server. The CMS, booking and live-rating add-ons need Vercel. Hosting compares all four.

Add-ons

At small-business volume, the CMS, booking and live-rating add-ons cost next to nothing extra to run: they use your hosting and your database, with no per-booking or platform fees. Once a booking client has their own domain, their booking emails go through a free email-sending account whose free tier covers one verified domain and about 3,000 emails a month.

The AI receptionist

The receptionist runs on a pay-as-you-go voice platform account, with a $5 minimum top-up.

• Pitching it costs about $1–2 a month for the one demo number, however many businesses you pitch, plus about 6–7 cents a minute when a prospect rings it.
• Each paying client gets their own number, about $1–2 a month, plus about 6–7 cents per answered minute and the texts to the owner (a cent or two each in the US, about 5–11 cents in the UK). A client whose phone forwards thirty calls a month typically costs $6–9; a busy trade's line can run to $25–40.
• In the US, the texts to owners need a one-time sender registration: about $19 once, then about $2 a month.

Apart from the demo line, these are costs you pass on. You charge each client a monthly fee for their receptionist, and their number, minutes and texts are a small slice of it, so nearly all of that fee is margin. See Pricing.

The account is prepaid, so keep it topped up: calls are turned away at a zero balance, the monthly number rental comes out of it, and an empty account can cost you a number. See AI receptionist.
