Our custom app development process

Scoping and Design

We start with thorough scoping and design, embedding security from the outset. This stage includes configuring the technical environment and setting up Infrastructure as Code (IaC) and CI/CD pipelines for seamless automated deployments across testing, user acceptance, and live environments.

Software Development

Our developers focus on the core engineering task, supported by thorough documentation and structured sprint planning. Regular reviews keep each stage aligned with project objectives and momentum on track.

Testing

We take a comprehensive approach to testing, combining manual and automated methods (BDD, Gherkin, Playwright) with dedicated user acceptance testing (UAT) to make sure the final product meets your quality standards and requirements.

Handover and Ongoing Support

We don't just hand over code and walk away. We offer mentoring and structured handover to your internal team, plus optional ongoing support covering Azure hosting, managed services, and licensing, so your solution stays robust and well-supported long after go-live.

Transparity worked seamlessly as an extension to the Courtiers project team, supporting the internal team members with technical guidance, knowledge and development capabilities to effectively deliver against the agreed objectives.

Custom application and Microsoft .Net development services

Build secure, scalable Azure‑hosted web applications that your team can access from anywhere, with real‑time collaboration and a seamless experience for staff and clients alike. With .NET, you get a powerful foundation for cloud‑native development in Azure — and with our team (who’ve been working with .NET since its launch in 2002), you’re in expert hands for creating modern, flexible apps that grow with your business.

Cross-Platform Mobile App Development

We build bespoke mobile applications using .NET MAUI, delivering cross-platform apps for iOS, Android, Windows, Xbox, and more from a single codebase. Faster delivery, consistent experience, and long-term maintainability.

Web Application Development Services

Experience the freedom and flexibility of Azure-hosted web applications, empowering your team to connect securely from anywhere, at any time. With seamless access for staff and clients alike, your organisation gains real-time collaboration, greater efficiency, and the agility to scale effortlessly as you grow.

Desktop Development

Some use cases still call for desktop or local network-based applications, field operations in developing countries, remote environments with limited connectivity, or specialist offline tools. Whatever your requirements, we can build for them.

.NET Core (.NET 10+)

All brand-new .NET projects we build use .NET Core, giving you an enterprise application that runs on Windows, Linux, macOS, and Docker, as well as device, cloud, and embedded systems from a single codebase.

.NET Framework

The .NET Framework provides a unified development structure for enterprise software, covering everything from file and network I/O to user interface, memory management, encryption, and exception handling. We've been building with it since day one.

Single Page Applications (SPA)

SPAs deliver a faster, more responsive user experience by dynamically managing a single page rather than constantly retrieving new ones from the server. We build SPAs using Blazor, Angular, or React for the front-end, with Web API, .NET, and Entity Framework handling the data layer.

Also expert in

ASP.NET (MVC and Web Forms), Web API (REST and SOAP), Entity Framework and ADO.NET, Entra ID, Entra External ID, Azure B2C, OAuth, and C#.

Scalability and flexibility

Built to grow with you, easy to extend, adapt, and scale as your needs evolve.

Security and reliability

Every solution we build meets the highest security standards and undergoes rigorous testing before it goes anywhere near your users.

Software designed for your processes improves efficiency and gives your team a real edge.

Integration

We build for your existing environment, ensuring smooth workflows and consistent data across all your tools and systems.

FAQs

NEED TO KNOW MORE ABOUT Custom Software Development??

What is custom software development?

Custom software development is the process of designing, creating, deploying, and maintaining software tailored specifically to address the unique needs of a particular organisation or user group, rather than adopting off-the-shelf solutions.

How is custom software different from ready-made solutions?

Unlike off-the-shelf software, custom applications are built from the ground up to match exact processes, workflows, and business goals. This often leads to improved efficiency, flexibility, and scalability.

Why should I outsource custom software development?

Outsourcing allows you to access a pool of specialised expertise, benefit from cost efficiencies, and speed up project delivery. It also enables your internal teams to focus on core business functions while experts manage the technological complexities.

Can outsourced teams work with my existing systems and technologies?

Yes. Skilled outsourcing teams are adept at integrating new software with legacy systems, APIs, databases, and third-party services to ensure smooth interoperability and minimal disruption.

What happens after the software is delivered?

Transparity offers comprehensive support and managed services, including updates, bug fixes, enhancements, and user training to keep your solution running smoothly over time.

What are the benefits of using .NET for custom software projects?

.NET is a robust, flexible, and secure framework that supports rapid development, integration with various technologies, and scalability for future growth. Its wide range of libraries and Microsoft support make it a reliable choice for both web, mobile and desktop applications.

Can .NET custom software integrate with my existing systems?

Absolutely. .NET supports integration with legacy systems, APIs, cloud services, and a variety of databases, enabling seamless connectivity across your organisation’s technology landscape.
