The moment a cancellation hits your calendar, FullSlot texts your entire waitlist. First to respond claims the slot. You find out it's filled — while you're still with another client.

Deposits help. Reminder texts help. But clients still cancel — and when they do, you're left with an empty slot, 20 minutes of phone calls, and almost nothing to show for it.

Revenue that never comes back
FullSlot runs in the background. You never have to touch it.
FullSlot detects it the moment it happens — Calendly, Google Calendar, Acuity, Square, Outlook, or anything else you already use. No action needed from you.
Broadcast to everyone at once, or let FullSlot notify your top-ranked clients first — VIPs, longest waiters, best responders. You choose the strategy.
While you're still with another client. Your dashboard tracks every slot filled, every dollar recovered, and the full notification timeline.
Smarter than a group text
Most tools blast everyone and hope someone responds. FullSlot gives you full control over who gets notified, when, and in what order — so the right client fills the slot every time.
Everyone on your waitlist gets notified the instant a slot opens. Fast, fair, first-come first-served. Best when speed matters more than rank.
Your highest-ranked clients — VIPs, longest waiters, most responsive — get notified first with a full hour to respond. If they pass, the next group gets their shot.
Scored automatically. No manual sorting.
When a client claims an earlier slot and already has a later booking, FullSlot releases their old appointment and broadcasts it automatically. You recover twice the revenue from a single cancellation.
Switch between modes anytime from Settings. No data loss, no downtime.
Know your numbers
FullSlot doesn't just fill slots — it shows you exactly what you recovered, what expired, and where you're still leaving money on the table.
A monthly view of every slot that opened up — from cancellations and ad-hoc openings — color-coded by outcome. Green means filled and paid. Amber means expired. See at a glance how much revenue you recovered vs. left on the table.
Fill rate, average response time, revenue recovered this month, and which clients are your best responders. See exactly what's working — and where slots are slipping through.
Import via CSV, add manually, or embed a self-join form on your website. VIP tagging, opt-out tracking, notification history — everything in one place.
Set a cancellation detection window so only relevant slots trigger notifications. Customize claim windows. Choose whether to notify everyone at once or start with a small group first.
Every appointment business has the same problem. FullSlot is the fix.
A same-day cancellation is $300–$1,500 gone. FullSlot texts your waitlist the moment a slot opens — no phone calls, no manual outreach.
Your chair sitting empty at 2pm is money left on the table. FullSlot keeps a live waitlist of clients who want in — and fills gaps automatically.
Whether you're a PT, chiropractor, or personal trainer — when a client cancels, someone else wants that spot. FullSlot connects them in seconds.
Without adding staff, without phone calls, without lifting a finger.
