Waiting list
Let customers join a waiting list when your calendar is full, and automatically offer them any slot that opens up.
When your online booking page has no free slots, the waiting list lets a customer ask to be notified instead of leaving without booking — and recovers the slot for you if someone else cancels.
How it works
- A customer joins the waiting list from your booking page when nothing suits them, choosing the service and how much notice they need before an offered slot.
- When an appointment is cancelled or a new slot opens up, Calendia offers it to the next eligible waiting customer by email or SMS.
- If they confirm, it becomes a real booking. If they decline or the offer expires, it passes automatically to the next person in line.
Turn on the waiting list
- Open Company settings and go to the Bookings tab.
- Tick Enable waiting list offers.
- Set Offer channel to Email, SMS, or Email and SMS.
- Set Offer expiry (in minutes) — how long a customer has to respond before the slot passes to the next person.
- Choose which Notice options customers can pick from when they join, so you never offer them a time they can't make.
- Click Save.

Review who's waiting
On the Bookings page, click the Waiting list button (with a badge showing how many are waiting) to open the panel of everyone currently waiting and any offer that's pending a reply. On the Dashboard, click the amber bar at the bottom of the calendar that says how many people are on the waiting list to open the same panel.
