Tired of Cashiers Waiting Minutes for POS Sessions to Load?
Standard Odoo POS re-downloads tens of thousands of products, prices, and customer records from the server every single time a session is opened. For large retail catalogs, this causes severe network congestion, server strain, and long waiting times for cashiers. POS Fast Loading Cache solves this permanently by caching master data locally in the cashier's browser!

Key Features & Capabilities
Empower your Point of Sale with modern client-side caching & deletion tracking.
Browser IndexedDB Storage
Master POS data is safely saved in the cashier's browser IndexedDB database, allowing initial session boots to load locally in milliseconds.
Incremental Delta Synchronization
Instead of downloading the whole catalog, Odoo only requests records updated since last sync (write_date > last_sync), saving massive bandwidth.
Automatic Deletion Tracking
Tracks records deleted on the backend while cashiers were offline or away, removing obsolete items from the browser cache seamlessly.
One-Click Invalidation & Versioning
Bump the Cache Format Version or hit Force Cache Reload per POS config to force browsers to discard outdated local cache after module upgrades.
Architecture & Code Integration
Extensible framework designed for seamless Odoo 15 POS store integration.
