Scope & Budget

Starter web apps from £699

A Starter Web App is built around one main workflow, with a responsive interface, authentication, database, user dashboard and basic administration. Multiple roles, payments, uploads and API integrations belong in a larger agreed scope. Business Web Apps start from £999 and advanced apps from £1,499.

Build around a real workflow

Customer portals, booking systems, dashboards and internal tools each solve a different problem. The first step is to define who will use the app, what they need to do and what information they can access. That becomes a clear feature list and a practical plan for the first release.

Screens, data and integrations

Dean builds the user interface alongside the data and access rules that support it. Depending on scope, this can include login, a database, administration, file uploads, email notifications or payment integration. Each feature is chosen for your workflow, with test cases based on what users should be able to do.

Launch with a useful handover

The app is tested against the agreed requirements before deployment and domain setup. The handover explains the accounts, code and day-to-day operation. Starter app packages include 30 days of bug-fix support; ongoing changes and maintenance are discussed separately so future work has a clear scope.

Product built by Dean

Bookrightly

A UK booking marketplace with public business profiles, online bookings, Stripe payments and dashboards. It demonstrates several workflows that can form part of a custom application, rather than a promise that every feature is included in a starter package.

FAQ

Questions about custom web app development.

What is included in a £699 starter web app?

The starter package covers one main workflow, a responsive interface, login and authentication, database, user dashboard, basic admin, forms, basic email notifications, deployment and 30 days of bug-fix support. The exact scope is agreed before the build.

Can a web app work on mobile?

Yes. Web apps can have responsive layouts for phones, tablets and desktops. If you need a progressive web app or a separate native mobile application, discuss those requirements during scoping.

Can you integrate Stripe or another API?

Yes. Payments and API integrations can be included in a Business Web App or a separately scoped project. Third-party account requirements and running costs are discussed before launch.

How long does web app development take?

Many scoped starter web apps take 1–2 weeks. Business web apps commonly take 1–3 weeks, while larger platforms need an individual schedule. Content, feedback and integration requirements affect the timeline.

Can you improve an existing app?

Yes. Share the current app, code access and the problems you want to solve. Dean reviews the existing setup before agreeing the changes, price and release plan.
