Frequently Asked Questions
Everything you need to know about SlotFill
When you broadcast an opening, all clients on your waitlist receive an SMS simultaneously 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.
