The short version
When an appointment cancels, an agent texts the waitlist in order and books the first person to reply yes.
What they did
When an appointment cancels, an agent texts the waitlist in order and books the first person to reply yes. The owner started with a small pilot: one workflow, a few days of supervised use where every output was reviewed before it went out, then gradually let routine cases run with lighter oversight.
Agent/tool used: Zapier + Square Appointments
How it went
In a typical rollout like this: more chairs/tables filled on short notice. Most of the value comes from consistency, the task happens every time instead of when someone remembers. Expect a week or two of tuning the prompt and rules.
Worth knowing
AI drafts can be wrong or off-tone. Keep a human approving anything customer-facing at first, don't paste sensitive data (card numbers, health records, SSNs) into general chat tools, and check each tool's data and privacy terms.
Copy-paste prompt
Write a short text to waitlisted customers: a [service] spot just opened at [time] on [day] at [Business Name]. First to reply YES gets it. Under 35 words.
Replace anything in [brackets] with your own details.
Step-by-step setup
- Write down how you handle this today, in 5-10 bullets.
- Connect or export data from Square, Zapier.
- Set up Zapier + Square Appointments and paste in the prompt, filling in the [placeholders].
- Test it on 5-10 real past examples and fix anything that's off.
- Run it with you approving every output for one to two weeks.
- Once you trust it, automate the routine cases and spot-check weekly.
