An offline-first business management system — billing, staff commissions, appointments, and customers, running on hardware you own, not someone else's server.

What's inside
Five modules. One system.
Billing & POS
PIN-based checkout, itemized billing, and a fast counter flow built for real traffic, not a demo.
Staff Commissions
Per-staff commission tracking calculated automatically on every billed service — no spreadsheet at month-end.
Appointments
A live booking calendar shared across counter and staff, so nobody double-books a chair or a slot.
Customer Database
Visit history, preferences, and notes per customer — so every staff member picks up where the last visit left off.
Owner Dashboard
Revenue, staff performance, and daily activity in one view — built for an owner who isn't standing at the counter all day.
WA Receipt Pro
Connects at checkout to send a formatted receipt straight to the customer's WhatsApp — no app required on their end.
Why it's built this way
Offline-first isn't a limitation.
01
Your data stays on your hardware
Billing, customer records, and staff data live on the machine you own — not on a server NYX or anyone else controls.
02
Internet drops don't stop your counter
Billing keeps working with no connection. Sync happens when you're back online — it's never a blocker.
03
Five roles, one login screen
PIN-based access for Counter, Staff, Manager, Owner, and Developer — everyone sees only what their role needs.
04
Built to expand without a rebuild
WA Receipt Pro is the first add-on connected to NYX SYS. The system is built so the next one plugs in the same way.
