Why choose our custom software solutions

Improved Speed to Market

We build on the Microsoft stack you already know, so there's no learning curve slowing you down. Your developers work with familiar tools, your infrastructure's already in place, and we deliver working software in weeks, not months. You'll ship faster because we're not starting from scratch.

Greater Customer Satisfaction

Custom apps built around your actual processes mean customers get what they need without fighting your systems. We design applications that solve real problems, not generic ones. The result? Fewer workarounds, happier customers, and software that actually supports your business instead of getting in the way.

Talent Retention

Good developers don't want to spend their time maintaining legacy systems or wrestling with outdated tools. We modernise your application estate using current Microsoft technologies through our application innovation services, giving your team interesting problems to solve and modern tech to work with. That's what keeps talented people around and reduces costly turnover.

FAQS

Need to know more about app innovation?

What is custom software development?

Custom software development is the process of designing, building, and deploying bespoke software solutions tailored specifically to your business requirements, rather than using off-the-shelf products.

What technologies do you use for bespoke software development?

We specialise in Microsoft technology including .NET, Azure application development, .NET MAUI for mobile apps, Power Platform, and other Microsoft stack technologies.

How long does custom app development take?

Timelines vary based on complexity. Simple applications might take 8 to 12 weeks, while complex custom software solutions can take 6 to 12 months. We will provide a realistic timeline after understanding your requirements.

What is application modernisation and do we need it?

Application modernisation updates legacy systems to modern technologies and architectures. If your current software is difficult to maintain, cannot scale, or relies on outdated technology, modernisation might be the right approach.

Can you integrate with our existing systems?

Yes. Our application integration services specialise in connecting custom software solutions with existing systems, whether they are legacy applications, modern cloud services, or third-party platforms.

Can you integrate with our existing systems?

Do you offer support after deployment?

Yes. We provide ongoing support, maintenance, and enhancement services for all custom software development projects. We can also transfer knowledge to your internal team if you prefer to manage support yourself.

What is .NET MAUI and when should we use it?

.NET MAUI is Microsoft's cross-platform framework for building native mobile and desktop apps. Use it when you need iOS, Android, and Windows applications that share a single codebase, reducing development costs and maintenance.

What is digital and application innovation?

Digital and application innovation refers to the practice of using modern software and technology to fundamentally improve how a business operates, delivers products, or serves customers. It goes beyond building or updating apps — it’s about identifying where technology can create a genuine competitive advantage. At Transparity, our digital and application innovation services span new build, modernisation, integration, and intelligent automation, all delivered on the Microsoft stack.

What is application innovation?

Application innovation is the process of creating, modernising, or enhancing applications to better support business goals, improve user experiences, and enable digital transformation. It often combines custom software solutions, integration, and modern cloud technologies to deliver measurable outcomes.
