A no-show is a slot you paid staff to fill and cannot resell. Most businesses accept them as weather. They are not: a booking that receives a reminder with an easy way to cancel is far more likely to arrive or to free the slot in time for someone else. Reminders are the cheapest automation a booking business can add.
The problem
- Bookings are confirmed once and never touched again.
- Customers forget, or remember and cannot find how to cancel.
- Staff phone the day's list by hand when they have time, which is never.
The solution
- Confirmation at booking, from your own address, with date, time, location, what to bring, and a cancel/reschedule link.
- Reminder 24 hours before by email and, where you have consent, SMS or WhatsApp.
- Reminder 2 hours before for services with a high no-show rate (salons, clinics, restaurants on weekends).
- One-tap cancel that frees the slot in the calendar and notifies the waitlist.
- Follow-up after: a thank-you and a review request — covered in automatic review requests.
How it runs
A scheduled task on your hosting runs every few minutes, finds bookings due for a reminder, sends it through your mailbox (and an SMS gateway if used), and records that it went. The rules — timings, channels, which services get the second reminder — live in the admin panel so you change them without a developer. Every send is logged, so "we never got a reminder" can be answered in seconds.
Consent and tone
Email reminders for a booking the customer made are expected and lawful everywhere. SMS and WhatsApp need explicit opt-in in most countries (TCPA in the US, PECR in the UK, Spam Act in Australia) — collect it as a tick-box at booking. Keep the message short, factual and from a recognisable sender name; a reminder that reads like an advert gets reported.
Reminders are typically a small addition to a booking panel or a clinic appointment panel — days of work that pay back in the first month of recovered slots.
