GlitterOn

GlitterOn's stock and its sales lived in separate places, which meant they disagreed. A salesperson quoting a customer had no reliable answer on what was actually available, and the warehouse learned about a sale after the fact. Both jobs happen away from a desk — one on a floor, one in front of a customer — and neither was going to be done in a spreadsheet on a laptop.

Build it as a progressive web app, so it installs on the phone already in the user's hand, survives a bad signal in a warehouse, and updates without an app store review. One stock number, written once, read by both sides. Sales and inventory as two views of the same data rather than two systems that reconcile later.

A custom PWA covering inventory management and sales, installable on any device, with one shared source of truth for stock.

• Installable PWA — no app store, works on the devices staff already carry
• Single stock ledger shared by inventory and sales
• Sales flow that reads live availability at the point of quoting
• Offline-tolerant behaviour for warehouse dead zones
• Role-based access so the floor and the sales team each see their own view
