Barcode Warehouse Scanner App
Offline-first inventory management for poor-connectivity warehouse environments
Inventory accuracy improved by 97%
Stock counting time reduced by 76%
Overview
Warehouses with inconsistent WiFi coverage cannot rely on cloud-first applications for critical inventory operations. We built an offline-first Android scanning application that allows warehouse teams to perform complete stock counts, receiving, and dispatch operations without an active network connection — synchronising automatically whenever signal is available.
The Challenge
Warehouse teams required reliable inventory updates in areas with poor or intermittent connectivity, using dedicated barcode scanning hardware.
The Solution
Created an offline-first Android application supporting barcode scanning, local stock management, inventory audits, and automatic background synchronisation.
How We Approached It
Offline Data Model
Designed a complete local data model so every operation works identically online and offline, with a sync queue for upstream propagation.
Scanner SDK Integration
Integrated hardware scanner trigger events for one-handed operation without requiring the touchscreen during scanning.
Sync Strategy
Implemented incremental sync with conflict detection and a visual indicator showing which records are pending upload.
Multi-Location Support
Extended the data model to support multiple warehouse locations with location-scoped inventory views.
