Application Development
Transform, automate, and innovate through bespoke software solutions
At C5 Alliance, we help organisations solve business challenges and unlock new opportunities through tailored software development.
Whether you need a custom app, a mobile solution, systems integrated or help with low-code automation, our team works alongside yours to deliver scalable, secure, user-friendly applications that drive measurable value.
We’re not just developers — we’re collaborators, advisors, and trusted partners.
Power Platform Development
Bespoke Software development
Built Around Your Business
Every solution starts with a conversation. We take the time to understand how your business works, where the challenges lie, and what success looks like for your team.
From there, we shape a solution around your goals — working in partnership with you through every stage of development.
We use Agile methodologies to keep projects transparent, flexible, and focused on what matters most. You’ll see working software early and often, giving you the chance to prioritise features and maximise your budget.
Microsoft Power Platform Development
Rapid, secure, low-code apps that drive real results
We build powerful business applications using Microsoft Power Platform — connecting Power Apps, Power Automate, and Power BI to the Microsoft ecosystem and beyond. These low-code tools enable faster development, seamless integration, and stunning data visualisation, helping you modernise manual processes and act on insights in real time.
We can develop both canvas and model-driven apps for specific tasks, such as inspections, compliance, field sales enablement, and more — all backed by secure integration with Microsoft 365, Dynamics 365, and Azure.
Bespoke Software Development
When off-the-shelf doesn’t fit, we build around you
Sometimes, you need something purpose-built. We design and develop bespoke solutions that integrate with your existing systems or completely transform a business function. From tactical tools to strategic enterprise applications, we cover front-end, back-end, cloud, on-premise, or hybrid solutions.
Our developers work closely with technical business analysts to ensure your goals are captured, your risks are addressed, and your application is fit for purpose — now and into the future.
Expert Support from Start to Finish
Technical Business Analysis
We offer Technical Business Analysts who bridge the gap between your team and our developers — translating your needs into clear requirements, mapping data flows, managing integrations, and ensuring GDPR compliance from day one.
UX & UI Design
User experience isn’t an afterthought — it’s at the heart of successful application development. Our NNG-certified UX team collaborates from the outset to create intuitive, accessible interfaces that reduce friction and boost adoption. Strong UX also helps reduce development costs by resolving user issues before they become rework.
Application Testing
We offer flexible, scalable testing services — including onshore resources who can work on-site, remote testing through our BDO network, or full responsibility for QA. From functional testing to best-practice code reviews, we help ensure your application is secure, stable, and ready for use.
Governance & Documentation
We help you align your applications with industry regulations and internal standards. We provide full technical documentation, including user journeys, integrations, supported platforms, and use cases — giving your investment a clear roadmap for the future.
