Websites, mobile apps and customer portals

We design and build websites, mobile apps and customer portals that let customers find what they need, book, pay or get support without calling you.

Each one connects to the systems your team already works in.

What we build

  • Business websites with clear service pages, enquiry forms and a structure search engines can read.
  • Mobile apps for customers, field staff or internal operations.
  • Customer portals for bookings, documents, orders, payments and support requests.
  • Interface design: research, user flows, prototypes and screens before anything is built.

Built to be found

Search engines and AI assistants such as ChatGPT, Gemini and Perplexity read the HTML a page sends, and many never run its JavaScript. Every page we ship carries its real text in the HTML, its own title and description, structured data and fast-loading images. This site is built the same way.

Connected, not standalone

A website that only collects emails leaves your team copying details by hand. We connect enquiries to your CRM or inbox, bookings to your calendar and orders to stock and accounts.

How a project runs

  1. Scoped before it is built. The first week maps the workflow, integrations and acceptance criteria. You approve a written scope and quotation that shows the work, estimated days and cost for each module.
  2. Built in the open. You see working software each week, so your team can test it while changes are still quick and inexpensive.
  3. Handed over, then supported. We launch on accounts in your name, test against the agreed criteria and document the system. Ongoing maintenance is optional.

Timeline is fixed in your written scope.

Common questions

Can you redesign our existing website?

Yes. We start with what your current site does well, what visitors look for and which pages bring enquiries, then rebuild or improve it. Old addresses are redirected to the new pages so existing search rankings carry over.

Do we need an app in the app stores?

Not always. We scope whether you need an app in the App Store and Google Play, a mobile web app, or both. For internal teams a mobile web app is often enough, and it costs less to maintain.

Who owns what you build?

You own your data, configuration, workflows, knowledge base and project documentation. Accounts and channels can be set up in your name. Twenty Growth retains its underlying platform, and your licence lets you run the delivered system and export your data.
