Lumea

Everything a beauty salon runs on, in one place: bookings, customer history, payments through EFT-POS and cash registers, staff and commissions, stock and official e-invoices. A small desktop bridge connects the physical POS devices that a browser cannot reach; the same backend serves web, iOS and Android.

The Problem

Salons juggle a booking app, a separate POS, a paper commission sheet and an accountant chasing invoices. Browser-based software cannot talk to the card terminal on the desk.

The Solution

A multi-tenant platform plus a single-file desktop bridge for Windows and macOS that links the POS hardware. E-invoice keys are encrypted at rest, and production invoicing can only be switched on deliberately.
