Fills your sudden openingsin a Flash.
Someone just cancelled. Instead of scrolling your contacts or posting a last-minute deal yourself, let FlashFill automatically text your waitlist, offer past clients a discount, and post to social — so that empty slot gets booked before you've even noticed it opened up.
No-code setup · No lost revenue left on the table · Cancel anytime
One cancellation. An automatic cascade.
You configure the tiers once — order, timing, audience, discount, channel — and FlashFill runs the whole recovery sequence every time, escalating automatically until the slot is filled.
Tier 1 · 0 minutes
Ping your waitlist instantly
The moment a slot opens, everyone on that service's waitlist gets an SMS or WhatsApp alert first — first come, first booked. No waitlist? FlashFill skips straight to Tier 2 in seconds.
Tier 2 · Minutes later
Offer past clients a discount
Still open? FlashFill texts a targeted segment of your past clients — filtered by service, staff, or how long it's been since their last visit — with a configurable discount to make it an easy yes.
Tier 3 · Last resort
Broadcast it publicly
Still no takers? FlashFill auto-generates a branded deal graphic and posts it to Instagram or Facebook, turning your empty slot into a public flash sale — no design work required.
Up to 5 tiers, fully configurable per business — skip, reorder, or turn off any tier from your dashboard.
Everything you need to stop losing revenue
FlashFill handles the outreach, the compliance, and the busywork — you just keep your calendar full.
Compliance-safe SMS & WhatsApp
Every message respects TCPA quiet hours, includes required opt-out language, and honors STOP replies automatically — no manual compliance babysitting.
Social auto-posting
When a slot goes to the public tier, FlashFill renders a branded deal graphic from your logo and colors and publishes it straight to Instagram or Facebook.
CSV import bridge
Booking system doesn't expose client phone numbers? Upload a CSV once to seed your customer list — numbers are validated and de-duplicated automatically.
Embeddable waitlist widget
Drop one line of JavaScript on your website and let visitors join your waitlist directly — no plugin, no app, no extra login for your clients.
No-code onboarding wizard
Connect your booking system, set your tiers and discounts, and you're live — no developer, no spreadsheet, no support ticket required.
Configurable discount tiers
Decide exactly how much to offer at each stage — smaller (or no) discount for your waitlist, bigger incentives the longer a slot sits open.
Built to keep you compliant, automatically
Real regulatory requirements, already handled — so you can focus on running your business, not reading legal text.
GDPR-compliant data handling
We store only what's needed to run recovery campaigns, and honor right-to-erasure requests with a hard delete across every record within 48 hours.
TCPA-compliant quiet hours
Outbound texts automatically respect each business's local time zone, holding off between 8pm and 8am so your clients never get a 2am flash-sale text.
Encrypted credential storage
Every connected integration token and API credential is encrypted at rest with AES-256 — never stored or transmitted in plain text.
Stop losing revenue to empty chairs.
Set up your recovery tiers in minutes and let FlashFill fill your next cancellation automatically — no code, no manual outreach.
