RetailKiosk — Unified Price Check System
PyQt6 · Flutter · ODOO · 24/7 Resilience · Live in 6 Branches
Most ERP data never leaves the back office. RetailKiosk makes Odoo accessible on the shop floor.
Traditional web-based kiosks fail in high-stakes retail due to session expiry, app escaping, and high maintenance. RetailKiosk is a dedicated application layer that makes Odoo's live data accessible reliably, without staff intervention, across any hardware the store already owns.
THE STANDARD APPROACH FAILS BECAUSE:
Odoo's data model is not uniform across deployments. A product might exist as a 'Unit' in one database and a 'CTN (20 pcs)' in another. RetailKiosk resolves what was actually scanned at query time — scan a unit, show unit price; scan a carton, show carton price. No assumptions. No hardcoding.
"Runtime unit-type resolution at query time — no hardcoding, no cache, no assumptions."
