A patient just cancelled their adjustment. Ten regulars would take that slot.
SlotFill texts your waitlist the moment an opening appears. First to respond gets it. You never pick up the phone.
The Cost of Empty Slots
You already know this feeling
You see 25 patients a day. At an 8-12% cancellation rate, that's 2-3 empty slots every single day. Each one is $50-100 gone.
The thing is, your maintenance patients are loyal. They come every week. They'd happily grab an earlier slot or a different day. They just don't know it's available.
Your front desk could text them. But between check-ins, co-pay collection, and the phone ringing every three minutes, the waitlist is nobody's priority. So those 2-3 slots sit empty. Every day. That's $500-1,500 per week walking out the door.
What if your waitlist worked for you?
When someone cancels, tap once. SlotFill texts your regulars who'd want that slot. The first one to reply "YES" is booked.
With 15-minute adjustments, speed matters more than anywhere else. By the time your front desk would have made two calls, SlotFill has already filled the slot.
Built for how chiropractic practices actually work
High volume means high cancellation volume. With 25+ patients per day, you can't afford to manually manage each opening. SlotFill handles it in one tap.
Your maintenance patients come weekly. They're already committed. They'll take any open slot that works — they just need to know it exists.
Shorter appointments mean the window to fill is smaller. SlotFill reaches your entire waitlist in seconds, not the 20 minutes it takes to call down a list.
No app for patients to download. A text message, a YES reply, done. Perfect for a high-volume practice where simplicity is everything.

Frequently Asked Questions
Everything you need to know about SlotFill
When you broadcast an opening, all eligible clients on your waitlist receive an SMS with a unique claim link. The first person to tap the link and confirm claims the slot. Everyone else sees a 'slot already claimed' message. It's fair, fast, and transparent.
No! That's one of the best parts. Clients receive a simple SMS with a link. They tap it, see the appointment details, and tap again to confirm. It works in any mobile browser - no app downloads, no account creation, no passwords to remember.
Absolutely. We use industry-standard encryption for all data in transit and at rest. We don't store session notes or clinical information, only the minimum contact info needed for scheduling. Your client list stays yours.
You have two options: add clients manually through your dashboard, or share your unique waitlist join link. Clients can add themselves via that link - they just enter their name and phone number. You can review and manage all waitlist members anytime.
Your regulars want their weekly adjustment. Your cancellations are leaving gaps. Connect the two.
