SlotFill vs Manual Calling
Still calling through your waitlist when a client cancels? There's a faster way. See how SlotFill replaces 20-30 minutes of phone tag with a single click.
Manual Calling Costs You 15-20 Hours Every Month
The average therapist spends 20-30 minutes per cancellation trying to fill the slot by phone. With 3-5 cancellations per week, that's 4-10 hours per month spent on phone tag — time you could spend with clients or on yourself.
SlotFill reduces each cancellation recovery to about 30 seconds. Broadcast to your waitlist, and the first client to respond gets the slot. No calls, no voicemails, no waiting.

Frequently Asked Questions
- How does SlotFill work compared to calling?
- When a client cancels, you create an opening in SlotFill and tap "Broadcast." SlotFill instantly sends an SMS to everyone on your waitlist with a link to claim the slot. The first person to tap the link gets it. No calling, no voicemails, no waiting for callbacks. The whole process takes about 30 seconds.
- Is texting from my personal phone a compliance risk?
- Yes. Under the Telephone Consumer Protection Act (TCPA), sending marketing or scheduling texts requires proper consent tracking and opt-out mechanisms. Texting from your personal phone has no opt-out system, exposes your number, and in group texts can expose clients' numbers to each other — a privacy violation. SlotFill handles all of this automatically with a dedicated business number.
- What if a client cancels after hours?
- With manual calling, you'd have to wait until business hours to start reaching out — by then the slot might be tomorrow morning. With SlotFill, you can set up the broadcast and clients can claim at any time via the web link. SlotFill respects quiet hours for sending SMS (no texts between 9pm-8am), but claim links work 24/7.
- How much time will I actually save?
- Most therapists report spending 20-30 minutes per cancellation when calling manually. With 3-5 cancellations per week, that's 4-10 hours per month. SlotFill reduces each cancellation to about 30 seconds of your time. Use our savings calculator to see your specific numbers.
