Inventory Management Application for a Motorcycle Accessories Store

The application allows users to scan product barcodes and instantly verify their accuracy against the database. If the scanned barcode matches an existing record, the inventory count is automatically updated. Users can finalize or partially complete inventory sessions. This provides users with flexibility if items are missing or pending arrival. Additionally, users can manually adjust inventory counts. If a product has multiple identical items, they can either scan each item separately or increment the count manually.

The app supports assigning multiple barcodes to a single product. For example, a product can have a manufacturer barcode and a store-specific barcode. We made the system allow users to link multiple barcodes to the same inventory item.

Leobit manually configured the Zebra printer using ZPL (Zebra Programming Language) to generate and print receipts in the correct format based on the paper type. This ensured that receipts were properly formatted and printed with the proper size and alignment.

The application’s user interface was built using Flutter, which provides a seamless and responsive experience across different screen sizes. Flutter was chosen for its ability to accelerate UI development while maintaining high performance on Android-based Zebra and Honeywell scanner devices. The framework also allows future expansion to iOS with minimal development effort by creating an additional communication bridge rather than building a separate app.

The application also featured tight integration with the client’s inventory module. API endpoints allowed the app to retrieve expected stock levels and send back real-time data on scanned items during inventory checks. The back end then calculated discrepancies, flagging shortages or overages. This enabled more accurate and efficient inventory tracking and helped eliminate manual reconciliation efforts.

Leobit suggested the use of Hive local storage to store and quickly retrieve scanned inventory data. It enables offline access and reduces dependency on constant backend synchronization.

When a product barcode is scanned, the system checks whether the price printed on the label matches the current database value. If there’s a discrepancy (e.g., the price has changed in the back end), the app automatically prompts the user to print an updated price label. These labels, which include the product name, price, and a QR code, can be scanned either by a mobile phone (redirecting to the product’s web page) or by the inventory scanner, which reads embedded price metadata for further validation.

To further improve the in-store experience, the app supported a self-scan shopping mode. Customers or shop employees could scan products directly into a digital cart, enabling faster checkout processes and simplified stock movement tracking. This feature laid the groundwork for future self-service scenarios, such as mobile-based shopping or assisted checkouts.
