SlotFill texts your waitlist the moment a slot opens. The first client to reply gets it. No phone calls, no list, no scramble.
Right now, someone on your waitlist would love your next open slot. They just don't know it's available yet.
Manual phone tag is exhausting. By the time you reach someone, the slot is already gone and the revenue with it.
Speed is everything. The first available client should get the spot — not whoever happens to answer their phone.
Last-minute cancellations aren't just inconvenient — they're expensive. Most appointment businesses lose $8K–$15K a month and don't realize it's recoverable.

See exactly what cancellations cost you — and what SlotFill puts back.
SlotFill runs silently in the background. The moment a slot opens, the engine fires — no manual work, no missed windows, no revenue left behind.
The moment a client cancels via Boulevard, Mindbody, or any connected system, SlotFill receives a real-time webhook notification. Your team doesn't have to do anything.
⚡ Under 3 secondsSlotFill ranks your entire waitlist using 7 factors — service match, spend tier, provider preference, response history, time preference, and more. Best match rises to the top.
🤖 7-factor AI scoringA personalized SMS goes to your top matches: "Hi Jennifer! A slot just opened — Today at 2 PM. Reply YES to grab it." First to respond gets booked. Done.
✅ Avg 3.8 min to fillYour front desk sees the gap. They pull up a list. They start calling. First person doesn't answer. Second person can't make it. Third person's number is wrong. By the time someone says yes — if anyone does — twenty minutes are gone and the slot is in an hour.
One tap. A text goes out to everyone on your waitlist who'd want that slot. The first client to reply "YES" gets it. Booked in under 4 minutes. Your front desk never made a call.
No app for clients to download. No calendar to sync. Just a text message and a filled appointment.
SlotFill is a complete revenue recovery operating system — not just a waitlist text blast.
Cancellation webhook fires → waitlist scored → personalized SMS sent → slot confirmed. The entire loop completes in under 4 minutes with zero human involvement. Your best waitlist client gets the slot before anyone else even knows it opened.
Core FeatureEvery client is scored in real time across spend tier, service match, provider preference, response rate, time preference, geographic proximity, and loyalty score. The right client always gets the right slot — not just whoever's first on a list.

SlotFill is currently live with a small group of founding clients. Every number below is from actual recovery data, not projections.
"A single-location clinic connected their Boulevard account and recovered 4 cancelled slots in the first two weeks — slots that would have sat empty. Setup took under 10 minutes."
"Before SlotFill, every cancellation was just lost. No system, no outreach, no recovery. Within 30 days the practice had a consistent process — and clients were responding to offers within minutes."
"The speed surprised us. We expected to wait hours for clients to reply. Instead, offers were getting claimed within minutes — including slots that came in after closing time. It runs without us."
We're onboarding a small number of businesses at a founding rate with hands-on support. You get a dedicated setup call, direct access to the team, and a locked-in price before we open to the public.
One recovered slot covers a full month of SlotFill. Everything beyond that is pure profit you weren't capturing before.

"I watched business owners lose thousands every week to cancellations — not because they lacked clients, but because nothing was connecting them automatically. So I built SlotFill."
— Founder of SlotFill · slotfill@slotfill.io
Every week you don't have SlotFill is a week of cancellations you can't get back. Setup takes under 10 minutes. No dev work. No contracts. No risk.
