    ACT XM

    A customer portal that replaced three disconnected tools

    The Challenge

    ACT XM’s team was managing client data across three separate platforms — none of which talked to each other. Every report took hours. Every client update meant manual data entry in three places.

    The Solution

    Extranet Systems built a unified web application that consolidated all three platforms into a single, secure, real-time portal — integrated directly with their existing data infrastructure.

    The Outcome

    Processing time dropped by 3× immediately. The team now works from a single source of truth — with real-time data, automated reporting, and full audit trails built in.

    "We went from three disconnected tools to one unified system in 12 weeks. The team hasn't looked back — and neither have we."

    Everything you need to know about building custom software with us

    We build a broad range of mobile applications, from native iOS and Android apps to cross-platform solutions using frameworks like React Native and Flutter. Whether you need a business tool, an e-commerce platform, or a social application, we tailor every solution to your specific requirements.

    Mobile app costs vary depending on complexity, features, design, and target platforms. We provide a detailed, transparent quote after an initial consultation where we take the time to understand your project scope and budget.

    Timelines depend on the complexity and features involved. Simpler apps can be delivered in as little as two to three months, while more complex builds may take six months or more. We'll give you a clear, detailed timeline following our initial discussions.

    Absolutely. We offer comprehensive post-launch support that includes regular updates, bug fixes, performance optimisation, and user feedback integration, keeping your app functional, current, and continuously improving.

    Mobile app development is the process of designing and building software applications that run on smartphones and tablets. Our developers draw on a wide range of programming languages and tools to create apps that are purpose-built for your users and business goals.
