Advanced Point-of-Sales SaaS Solution

    Client and challenge

    Our client provides administrative and predictive SaaS tools to businesses of all sizes and industries. These tools enable effective management of products, services, promotions, customers and interaction points.

    Although they had a cloud-based POS backend for inventory management and financial reporting, our client wanted to develop a front-end POS application compatible with a range of devices — from tablets to PCs.

    Initially working with another vendor, our client was dissatisfied with the development speed and quality of software, and our engineers were invited to review, refactor and optimize the app’s code. Our efforts led to the client entrusting us with the complete SaaS development, including a POS application for Windows touch screen devices.

    Our key tasks included ensuring consistency across device interfaces, enabling offline functionality and data synchronization, integration with the existing GraphQL API POS backend, customisable UI branding and layout, and compatibility with various peripherals.

    Our team of engineers successfully developed two responsive client POS applications – one for iOS and Android handheld devices, and another for Windows 10 devices. Both apps feature offline functionality and data synchronization with the cloud inventory management tool when internet connectivity is restored.

    In addition, our POS apps enable customisation during installation, allowing managers to edit product and service lists through the front-end app or inventory management tool.
