Why custom

Why custom over off-the-shelf.

You stop paying per-user fees on a tool that solves 70% of your problem. You add the missing 30%. You own the code. You scale on your roadmap, not someone else's pricing tiers. When the market moves, your software moves with it — because it's yours.

FAQs

Web application development, answered.

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

A website is read-mostly content. A web application is a software product running in the browser — users log in, perform actions, data persists, integrations fire.

Should I build a custom web app or use Bubble / Retool / Airtable?

No-code is great for a prototype or an internal MVP. Once you need real performance, complex permissions, custom UX, integrations or scale beyond ~50 active users, custom code wins on long-term cost and flexibility.

How long to ship a custom web application?

Eight to twelve weeks for a focused MVP. Four to six months for a full platform.

Will the app work on mobile?

Yes — every web app we build is responsive and PWA-ready. Native mobile apps are a separate add-on.

Can you integrate with our existing systems?

Yes — Salesforce, HubSpot, Xero, QuickBooks, SAP, Sage, Stripe, custom legacy APIs and more.

Where will the app be hosted?

AWS, Azure or GCP — UK regions by default for data residency. We set up the infrastructure and hand over keys.
