FAQ
Common questions
Do I need to change my scheduler?
No. FillFlow works with Google Calendar. Keep using whatever scheduling tool you prefer.
Why not just text my clients myself?
Speed wins the slot. By the time you text a few people and wait for replies, the opening is gone. FillFlow closes it in seconds.
What if nobody claims the slot?
We time out the offer and notify you. You can decide to open it to the broader list or leave it open.
Is SMS compliance included?
Yes. We collect consent, send opt-in confirmation, and honor STOP automatically.
Can I control who gets offers?
Yes. You can set VIPs, ordering rules, and caps so the right clients get first access.
How fast is setup?
Most coaches connect their calendar and add a few waitlist clients in under 3 minutes.
