KerAwen – Flutter mobile application for connected cash register

The Project

In a world where mobility and flexibility have become essential for retailers, KerAwen, publisher of AFNOR-certified NF 525 cash register software, wanted to expand its offering with a complete mobile solution. The goal? To allow its customers to manage their store anywhere, anytime, from a smartphone or tablet. To achieve this ambition, KerAwen called on Gopadma, our agency specializing in the development of custom mobile applications. Together, we designed a Flutter mobile application, compatible with Android and iOS, which incorporates all of KerAwen’s key features and adapts them for mobile use.

Key Features of the Application

A clear need: mobile store management

Today’s retailers need responsiveness and efficiency. Whether creating a product in real time, managing inventory, or checking out a customer on the go, a mobile solution is essential. KerAwen, already recognized for its omnichannel checkout software (sales management, inventory, supplier orders, inter-store transfers, etc.), wanted to offer its users the ability to access these tools directly from their mobile devices.

The challenge was multiple:

• Facilitate data entry and management (product creation, updates with barcode scan searches, etc.).
• Enable collection and payment based on the device used
• Add targeted features on certain specialized mobile terminals, such as the SUNMI V2, V3 or the LANDI C20, M20, among others:
  • Collection and payment by credit card
  • Printing receipts
  • Cash drawer management

Flutter: the Technological choice for a high-performance, cross-platform application

To meet these needs, Gopadma opted for the Flutter framework, developed by Google. This choice was made for several reasons:

• A single code base for Android and iOS: Flutter allows you to develop a single application, compatible with both major mobile operating systems, thus reducing costs and development time.
• A smooth and modern user experience: Thanks to its customizable widgets, Flutter offers an intuitive and responsive interface, adapted to the needs of merchants.
• Possible integration with Android devices LANDI and SUNMI: Since the application must communicate with certain specialized mobile devices, it was necessary to install certain libraries provided by these solution providers in order to benefit from advanced features: printing, data management, cash drawer, etc. This integration is only available on the Android environment. Indeed, Flutter allows for the addition of different features depending on the operating system.

Key Features of the KerAwen Mobile App

1. Real-time Product Management and Inventory

• • On-the-Fly Product Creation: Users can add new products directly from their mobile device, with the ability to enter all the necessary information (price, stock, category, etc.).
  • Barcode Scanning: Using the smartphone or tablet’s camera, merchants scan barcodes for fast and error-free entry. This saves valuable time when creating products, or searching for existing products during inventories, for example.

2. Mobile checkout and payment

• • Compatibility with SUNMI and LANDI terminals: The application allows you to receive payments (credit card, contactless, etc.) and print receipts. directly from these devices, transforming a simple smartphone or tablet into a complete mobile cash register.
  • Synchronization with KerAwen software: All transactions are automatically synchronized with the PrestaShop back office and KerAwen tools, ensuring unified sales management, whether in-store or on the go.

3. Omnichannel and data synchronization

• • Access to inventories, supplier orders, and inter-store transfers: Logistics professionals view and manage their orders and transfers from their mobile devices, with real-time updates.
  • Dashboard Customizable: Quick access to key indicators (sales, inventory levels, etc.) to manage business wherever they are.

An application designed for retailers, by experts

The development of the KerAwen mobile application was carried out in close collaboration with KerAwen teams and retailer users. This approach made it possible to:

• Validate field needs and adjust features accordingly.
• Test ergonomics to ensure intuitive handling, even for users less familiar with digital tools.
• Optimize performance for seamless use, even in busy situations or with a limited internet connection.
