Offline-First Retail System
High-speed, offline-first Point of Sale & inventory system engineered for retail checkouts, barcode scanning, and thermal receipt printing.
The Core Challenge
Retail hardware stores handling thousands of packaged and loose items face severe checkout bottlenecks and pricing mistakes when relying on handwritten paper bills.
The store operated entirely with handwritten paper receipt books and manual calculator arithmetic. With thousands of products, looking up prices by memory caused slow queues, pricing discrepancies, and zero inventory tracking—forcing the owner to visually inspect shelves to know what to reorder.
Build a high-speed, offline-first cashier terminal that scans barcodes, searches unbarcoded items in milliseconds, prints thermal receipts, and syncs sales data to the cloud whenever online.
Strategic Approach & Solution Plan
Store full product catalog and pricing in a local SQLite database for instant, offline terminal lookups
Support high-speed barcode scanning alongside instant keyword search for loose, unbarcoded hardware items
Integrate direct USB thermal receipt printing to issue clear, itemized customer receipts in under a second
Track real-time inventory counts with automated low-stock warnings and cloud revenue reporting with Supabase
By replacing slow handwritten paper bills with an instant offline-first terminal, the store eliminated math errors, accelerated checkout lines, and gained complete clarity over inventory and daily revenue.
