FAQs

Frequently asked questions

What's the difference between a website and a web app?

A website mainly shows information. A web application lets users do things, log in, manage data, make bookings, run reports or carry out tasks. If you need interactivity and accounts, you need a web app.

Can you build a SaaS product?

Yes. We build SaaS platforms from initial MVP through to a full product, including user accounts, subscription billing, admin dashboards and the features your customers need.

Will my web app be secure?

Security is built in from the start, secure authentication, encrypted data, role-based access and hardened hosting all come as standard.

Can it integrate with our existing systems?

Yes. We connect web apps to payment providers, CRMs, accounting tools and other software through APIs so everything works together.

How much does a web app cost?

It depends on the features and complexity. We scope your requirements, give you a clear fixed quote, and can build in phases so you can launch an MVP first and grow from there.
