The problem it solves

Every no-show costs you a table and the revenue that should have come with it, but calling every customer by hand to remind them is not realistic during a busy day. Staff end up either skipping reminder calls or losing time they could spend on guests in front of them.

Who it fits

Restaurants and other appointment-based businesses like salons that want to reduce no-shows without staff making the calls.

How it works

  1. Every day at a set time, the system checks the reservation list for that day
  2. For each reservation, AI writes a short, natural reminder message
  3. Twilio calls the customer and reads the reminder aloud
  4. The reservation is marked as called so no one is contacted twice

You decide how many no-shows a reminder would have prevented, from your own experience. We assume no rate, and we do not count slots you would have refilled anyway.

What you get

A phone call reminding each customer of their reservation, plus an updated log of who was called.

What you need

A Twilio account for phone calls, an OpenRouter API key for AI messages, and a Google account for Sheets.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
