Enterprise scheduling, made simple
Qssly moves complexity away from fragile application code, providing a headless API service you can trust.
Enterprise Data Isolation
Clean boundaries for all business data.
Instead of building complex custom checks to protect data access, Qssly isolates datasets cleanly per organization, facility, or branch.
✓ Complete cross-branch privacy:
Customer details, keys, and reservations are physically separated. Staff members and API connections see only what belongs to their authorized context.
Atomic Overlap Protection
Atomic conflict prevention blocks double bookings.
Most scheduling systems check availability in code and then save. Under high load, concurrent requests sneak through, causing duplicate scheduling conflicts.
✓ Atomic conflict prevention guarantees:
Qssly validates date ranges atomically. If a slot is taken, overlapping attempts fail instantly with a `409 Conflict` exception.
Transactional Webhooks
Reliable notifications with auto-retries.
Sync booking details immediately with your external PMS, CRM, or custom application. Webhook notification payloads are signed with secure HMAC signatures to verify origin integrity.
✓ Smart delivery retries:
If your service is down, our server automatically retries 5 times with exponential backoff. Failed payloads will be dropped after the maximum number of retries. See the webhook signature verification guide for web framework integration examples.
Mobile Operations App
Front-desk in your pocket with biometric security.
Operators don't sit in front of laptops all day. The standalone Qssly Business mobile app provides instant check-in management, real-time push alerts, 3-tap walk-in registrations, and quick room capacity controls on Android and iOS.
✓ On-the-go floor capabilities:
Secured via native Biometric Authentication (FaceID/Fingerprint) and backed by enterprise tenant isolation. Available for instant APK download and device pairing.
