Your Waitlist Is Full. Your Schedule Shouldn't Have Gaps.

When a client cancels, FullSlot immediately texts everyone on your waitlist. First to respond gets the slot. You find out it's filled — while you're still in session.

You Have a Waitlist. That's the Problem You've Already Solved.

People want your sessions. But when someone cancels, that slot goes empty while your waitlist sits there — untouched. You're between clients, can't make calls, and by the time you can, the hour's gone.

"I had 18 people on my waitlist and still lost 4 sessions last month. I just couldn't get to the phone fast enough between appointments."
