About the company
Posude is a retail company aiming to digitalize and simplify the work of its field sales teams. By providing a mobile solution that functions without internet access and syncs with the company’s internal systems, Posude has improved operational efficiency and reduced manual workload for its employees.
Project Overview
Posude engaged Intelvision to bring their mobile app idea to life—from architecture planning to launch. The main challenge was creating a stable, modular solution with offline support, tailored UX, and a synchronized database. Intelvision’s tailored Talent as a Service model enabled the client to build the app within budget and deadlines, delivering a stable, high-coverage product with intuitive order and customer management workflows.
Challenges and Pains
No Existing Application
Posude needed to build a mobile application entirely from scratch. The client lacked a previous solution, meaning the product had to be designed, architected, and developed from the ground up with no legacy systems or reusable components.
Unstable Internet Access in Field Conditions
The client’s sales representatives operated in locations with limited or no internet connectivity. Ensuring uninterrupted functionality in offline environments was a critical requirement—one that many off-the-shelf tools couldn’t fulfill effectively.
Budget Constraints with High UX Expectations
While aiming to provide a modern and intuitive experience for mobile users, the client also had to remain within a limited budget. Balancing cost efficiency with high UX standards required careful architectural decisions and expert resource allocation.
Maintainability and Scalability
The app needed to be maintainable, modular, and future-proof. The client expected a clean architecture with high test coverage, making long-term maintenance and ongoing development sustainable despite resource limitations.
Solution
Intelvision assembled a compact, expert team and delivered a fully functional mobile application in just three months—on time and on budget:
- Efficient Staffing
Within 12 days, Intelvision deployed a Full-Stack developer, and QA engineer. This lean team worked closely with the client to translate business requirements into a scalable mobile solution.
- Robust Offline Architecture
To address field connectivity issues, the app was built with offline-first capabilities. Sales reps could work without an internet connection and seamlessly sync data to the CRM once reconnected. - Smart Tech Stack Decisions
Using Xamarin Forms and the MVVM pattern with the Prism Library ensured long-term maintainability and modularity. This approach supported both performance and future scalability while staying within budget. - Streamlined Order Workflows
Custom controls, keyboard input, and a simplified order flow enabled fast, accurate data entry. The app’s UX was tailored for mobile efficiency, allowing users to manage customer orders with ease—from product selection to signature approval.
