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.

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."
— Solo therapist, early beta research
Lost per year to cancellations
Therapist at 25 clients/week, 15% cancel rate
Cancellation rate in private practice
One of the highest rates in healthcare
To handle it manually, mid-session
You're with a client. You can't stop.
FullSlot runs in the background so you never have to stop what you're doing.
FullSlot detects it the moment it happens through your scheduler or the Webhook Bridge — no action needed from you.
Every client waiting for a session gets an instant SMS with a link to book the slot.
Slot filled, revenue recovered — while you were still in your previous session.
Without phone calls, without interrupting your sessions, without lifting a finger.

Most appointment businesses try to fill cancellations by hand — calls, texts, social posts. It's slow, and by the time you've reached the third person, the slot is two hours out. FullSlot handles it automatically.
Cancellation
Waitlist never hears about it
You're treating a client. The front desk is on hold. By 1:45, it's too late to fill.
Filled automatically
Waitlist notified, first response wins
You were still with your 1pm client. FullSlot sent the text, took the claim, and the day stayed full.
Adjust the numbers to match your business. The math will do the rest.
