Spa management software that works even without internet
REENG is the offline-first spa management software trusted by spa owners around the world. Take bookings, run check-ins, take payments, and print receipts — even when your wifi drops.
Why offline-first matters
Spas lose money every time the internet goes down: bookings can't be confirmed, payments can't be processed, and staff can't check guests in. REENG runs entirely in your browser as a PWA, with full data sync the moment your connection comes back. Your front desk never stops.
Works when your internet doesn't
Your internet drops at 2pm. Your busiest hour. With other apps, everything stops. With REENG, nothing changes. Your staff keeps booking, your POS keeps processing, your data syncs when you're back online.
Internet drops
WiFi goes down. Other apps freeze. Your customers are waiting.
REENG keeps working
Bookings, payments, receipts — everything works locally on your device.
Data syncs automatically
When internet returns, everything syncs in the background. No data loss, ever.

Spa software FAQ
- Is REENG really free for spas to try?
- Yes. The Pro plan is free for 3 months — full features, every spa size. No credit card required to start the trial.
- Does REENG work offline at the front desk?
- Yes. REENG is built offline-first. Bookings, check-ins, payments, and receipt printing all work without internet. Data syncs back to the cloud automatically once you reconnect.
- Can REENG handle multi-therapist visits and packages?
- Yes. Visits support multiple therapists per guest, equal-split billing, package services, and per-therapist tip tracking — built for spas, not retrofitted from a generic POS.

- Yes. The Starter plan (1 outlet, up to 3 staff) covers solo and micro-spas. You can upgrade to Pro when you grow.
- Can I print thermal receipts and tax invoices?
- Yes. REENG prints to thermal receipt printers via QZ Tray and supports country-specific tax invoices (Vietnam compliant out of the box, more regions in progress).
