    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."

    Built Around Your Workflows

    Web Applications That Work the Way You Do

    Generic software forces your business to adapt to its limitations. A custom web application is engineered around your specific workflows, your users, and your business objectives so every feature serves a purpose and nothing gets in the way.

    Built for How You Work

    A custom web application is engineered around your workflows, your users, and your specific business objectives.

    Accessible Anywhere

    Your team and customers can access your web application from any device with a browser, from anywhere.

    Questions

    Everything you need to know about building custom software with us

    A custom web application is built specifically for your business rather than adapted from a generic product. It aligns with your exact workflows, integrates with your existing systems, and gives you full ownership of the code without ongoing licence fees or vendor lock-in.

    We build web applications using modern, proven frameworks and technologies selected based on your specific requirements, timeline, and technical environment. We recommend the right tools for your project rather than applying a one-size-fits-all approach.

    Security is built into every stage of the process, from threat modelling during design through to hardened infrastructure, penetration testing, and ongoing security updates once your application is in production.

    Yes. We can overhaul legacy applications, optimise the user interface for modern browsers and mobile devices, and address compatibility issues to bring older systems in line with current standards.

    We begin with a thorough discovery phase covering your business objectives, workflow mapping, and system integration planning. From there we move into agile development with regular feedback and collaboration, followed by rigorous testing, deployment, and post-launch support.

    Absolutely. We provide ongoing support and maintenance after go-live to keep your application stable, secure, and performing at its best as your business needs evolve.
