Bring the hustle to your booking system.

Let FlashFill manage the stress of filling your schedule, in three easy steps.

Connect

Connect to your existing booking system (Calendly, Acuity, Mindbody, etc.) with secure OAuth authentication. FlashFill automatically syncs your calendar and contacts.

Target

Create smart notification filters that target the right people. Someone who's booked a massage three times gets notified about massage openings, not facials.

Notify

When a slot opens up, FlashFill instantly sends targeted notifications with automatic discount codes to your most likely-to-book clients via email or SMS.

Everything you need to fill empty slots

Powerful features designed to maximize your revenue from last-minute cancellations.

Smart Targeting

Intelligent notification filters ensure the right people get the right alerts. Target based on booking history, engagement scores, and more.

Auto Discount Codes

Automatically generate single-use discount codes for each notification. Percentage or fixed-amount discounts with configurable expiration.

Revenue Tracking

Track every notification, booking, and dollar generated. Comprehensive analytics show you exactly how FlashFill drives revenue.

Real-Time Monitoring

Webhook support for instant notifications when slots open up. Automated checks ensure nothing falls through the cracks.

Multi-Channel Alerts

Send notifications via email or SMS. Track engagement rates, opens, clicks, and booking completions across all channels.

Frequency Protection

Prevent contact fatigue with message frequency limits. Automatic opt-out management ensures compliance and maintains sender reputation.

Simple, commission-based pricing

Only pay when FlashFill successfully fills a slot that would have otherwise gone empty.
