With a growing business that spans ingredient sourcing, production, distribution, and sales, the company required a robust digital backbone to manage its complex operations. The client sought a reliable partner to design and implement a comprehensive ERP system that could integrate multiple business functions into one unified solution, reduce manual work, and increase overall efficiency.

Project Overview

The client partnered with Sanmark Solutions to design and implement a full-featured Enterprise Resource Planning (ERP) system tailored to the unique needs of the dairy industry. The goal was to streamline every stage of their operations—from raw ingredient collection to final product distribution—while ensuring transparency, accountability, and ease of management.

The project started with a small-scale implementation focused on critical needs, and over time, the system grew to incorporate advanced modules that now support the company’s end-to-end business functions. Alongside the web-based ERP platform, we also developed a mobile app for sales representatives and field staff, which has already been highlighted as a separate success story.

Our Approach and Execution

Our approach to building the Royal Dairy ERP system was incremental, beginning with a smaller solution that tackled immediate challenges and gradually expanding it into a full-featured platform. One of the most notable milestones was the development of the Royal Sales App, which required our team to adopt Flutter from scratch—an exciting challenge that ultimately resulted in a robust and user-friendly mobile solution. Throughout the project, we faced the task of digitizing highly manual processes while ensuring smooth user adoption, designing a system flexible enough to support future growth, and integrating seamlessly between web and mobile platforms.

Each milestone, from production tracking to accounting and mobile capabilities, was executed with precision through automated workflows, a centralized database, and scalable architecture. A cross-functional team of developers, QA engineers, UI/UX designers, and project managers collaborated closely to ensure every feature aligned with the client’s operational needs, delivering a powerful system ready for real-world application.

Technology stack

The ERP system was primarily built using PHP, ensuring a stable and scalable backend for handling complex business processes.

For the mobile app, we used Flutter for mobile development, Dart as the programming language, Bloc for state management, and SQLite for local database management, providing a solid and responsive framework for the mobile app.
