Our Services

From ecommerce platforms to legacy modernisation, we deliver solutions that drive growth.

Ecommerce Development

Build and improve ecommerce platforms that integrate properly with your accounting, ERP, inventory and other business systems.

Legacy Software Upgrades

Modernise ageing Access, VB6, .NET and other business-critical applications without unnecessarily rebuilding everything from scratch.

Custom Software Development

Build software around the way your business actually works when spreadsheets or off-the-shelf products no longer fit.

Why Choose CoSource?

Experienced people, practical advice and software built around what your business actually needs.

More than 25 years of software development experience

We've been building business software since long before today's frameworks and AI tools existed. That experience helps us recognise what should be modernised, what should be retained and what should be built differently.

Experience across both legacy and modern technology

From Microsoft Access and older .NET applications through to Azure, modern web platforms and AI, we can work with the system you have, not just the technology we would prefer you to use.

Start with a free conversation with an expert

Talk through your project, existing system or business problem with an experienced software specialist. We'll help you understand your options and sensible next steps.

Ongoing support when the project is finished

We can continue maintaining, improving and supporting your software after launch, so you are not left looking for another development team.

You retain full ownership of your software

Your organisation owns the source code and the software we build for you. You are not locked into CoSource or a proprietary development platform.
