Desktop + Mobile — Better Together (Hybrid Enablement)
Desktop (Master)
Billing, stock, heavy ops
2-Way Sync Tool
Our hybrid engine — encrypted, queued, conflict-aware
Mobile (Extension)
Ordering, alerts, approvals

Flow: Desktop is master — mobile extends it. Waiter takes order on phone → KOT to kitchen → desktop auto-updates. Owner approves discount on phone → desktop applies. Same as WelHotels Hybrid (local ↔ cloud) — adapted for Desktop ↔ Mobile.

Hybrid Option
Offline-first mobile + online sync — works without internet, syncs when back (like Hybrid PMS).
One Codebase Where Possible
Hybrid HTML5/CSS3/JS reused for Android & iOS — cost & time saved.
Native When Needed
Heavy hardware/camera/GPS → native modules, still one team.
Why Desktop + Mobile from One Team?
  • Single business logic — no double maintenance
  • One vendor, one support — no blame game
  • Consistent UX across counter & pocket
  • Faster to market — hybrid reuse
