Bar POS software that works even without internet
Offline-first bar POS software: keep tabs open all night and split the bill fast at close — even when your wifi drops.
Why offline-first matters
A bar can't stop pouring because the internet went down mid-service. REENG runs entirely in your browser as a PWA, so open tabs, checkout, and receipts keep working offline through the whole night and sync back automatically when you reconnect.
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.
