Web Application Questions

Straight answers to the questions we hear most often.

What is a bespoke web application?

Software that runs in the browser and is built specifically for your organisation, rather than adapted from an off-the-shelf product. It fits your workflows and connects to the systems you already use.

When is bespoke better than off-the-shelf software?

When off-the-shelf tools force workarounds, duplicate data across systems or can’t give your customers the experience you want. If an existing product already does the job well, we’ll say so, and help you integrate it instead.

Can you build mobile apps as well?

Yes. We build iOS and Android apps from a single codebase with native, responsive UI. For the Rail Delivery Group we built Passenger Assist, a multi-platform app that helps rail staff assist disabled passengers across the UK rail network.

Will the application integrate with our existing systems?

Yes. API integration is part of most applications we build, connecting CRMs, payment providers, data sources and legacy platforms. If your systems need rationalising first, our sister team IXN Consult can help.

How quickly can you deliver?

We combine seasoned developers with AI tools, which lets us deliver in weeks, not months. Timelines depend on scope, and you’ll have a clear plan after discovery.

Do you support applications after launch?

Yes. We maintain, protect and improve the applications we build. We have supported Passenger Assist for five years.
