Running costs
What it coststo run.
You pay Twilio and xAI directly, on your own card, at their list prices. Nothing comes to Always Building each month. Spending limits and alerts are set up for you, so a busy month can't surprise you.
Typical total: £15 to £35 a month. Many AI receptionist services charge £99 to £349 a month on top of set-up. With yours, after the one-off set-up you pay only the running costs.
Twilio
The phone number and the minutes. Billed to your card, in your account.
xAI
The voice AI that talks to callers. Billed to your card, in your account.
Your server host, if needed
DigitalOcean or Render, about £5 a month. Billed to your card, in your account.
Always Building

Prices are set by the providers and can change. Checked October 2026: xAI model pricing, Twilio voice pricing (UK), Twilio SMS pricing (UK), DigitalOcean droplets, Render pricing.
