Worth the math

What does a no-show actually cost you?

A single missed appointment is rarely just one lost slot: it's the time, the prep, and the opportunity to book someone else. Even recovering a handful of no-shows each month may help offset the cost of SMS Reminder.

Adjust the numbers on the right to see what automated reminders could mean for your bottom line.

Start free with a booking page on your primary calendar. Paid plans from $19/month USD — cancel any time.
