Web application development for UK businesses

We design and build web applications for UK companies: customer portals, booking systems, dashboards and the admin screens behind them. The first call is free, a written proposal with the price and timeline follows it, and a first version starts from £1,999.

What we build

A web application is software people log into to get work done. These are the kinds we are asked for most often.

Customer portals
A login area where your customers see their orders, documents, bookings and invoices, and stop phoning the office to ask.
Booking and scheduling systems
Calendars, availability rules, reminders and payments. Prep2Pass, a driving school platform we built, schedules lessons across students and instructors.
Dashboards and reporting
One screen that takes the numbers out of the spreadsheets and shows what happened this week, with an export for the accountant.
Back-office admin
The screens your staff use all day: records, approvals, permissions and a history of who changed what. We build these as a custom or Filament admin dashboard.
Subscription products
Accounts, plans, billing and onboarding for software you sell to other businesses.

Work we have shipped

Two public projects you can open in a browser now: a Laravel platform and a Next.js website.

“Before working with Boolet, our internal processes were slow and fragmented. Their custom software streamlined everything into one platform, saving us hours each week. Boolet exceeded our expectations, the team was highly professional throughout the project.”
Phillip, Founder & CEO at Prep2Pass

How it works and how long it takes

Three steps before launch, each with a price or a date attached.

  1. A free call

    30 minutes

    You describe the problem. We say whether it needs custom software at all, and roughly which price band it falls into.

  2. Written proposal

    No charge

    After the call we send a written proposal: what the first version includes, what it leaves out, and the price and timeline for your requirements. You agree it in writing before the build starts.

  3. Build

    4 to 10 weeks

    An MVP usually takes 4 to 5 weeks and a Product build 10 to 12. You talk to the people writing the code, with no account manager in between.

What it costs

Software is priced on your requirements. These figures are starting points, and the price moves up or down with the size and complexity of what you need.

  • MVP

    From £1,999

    4 to 5 weeks.

    • One core workflow
    • Unlimited user roles
    • Admin panel
    • 30 days of support
  • Product

    From £4,999

    10 to 12 weeks.

    • Unlimited user roles
    • An API
    • Up to three integrations
    • 60 days of support
  • Enterprise

    From £9,599

    Timeline set in your proposal.

    • Multi-tenant accounts
    • Architecture review
    • Security review
    • 90 days of support

After the first call you get a written proposal with your price and timeline. After launch, support runs on a monthly plan from £199, or you can buy support hours separately, from £50 per hour, as needed.

What we build it with

We choose tools that plenty of other developers know, so you are never locked in to us.

Laravel and PHP
For applications built around data, rules and user roles. Mature, well documented and quick to build in.
Custom or Filament admin dashboard
For the admin side. With Filament, tables, forms and permissions arrive in days. When your process does not fit it, we build the dashboard to measure.
Next.js and React
When the interface is the product, or public pages need to load fast and rank in search.
React.js or Vue.js with Inertia
For rich screens inside a Laravel application, without a separate API to maintain.
MySQL or PostgreSQL on AWS
Standard databases and standard hosting. Nothing exotic to maintain.
Pest and PHPUnit
Automated tests, written test-first on the parts that matter, so changes do not quietly break what already works.

When you do not need a custom web app

Custom software is the expensive answer. We would rather tell you on the first call than after an invoice.

An off-the-shelf tool is enough when

  • An existing product already does the job and you can live with how it works.
  • Fewer than a handful of people will use it, and a shared spreadsheet is holding up.
  • You need a website with a form, which is a £499 job, not a custom build.

Custom is worth it when

  • Your process is the thing that sets you apart, and no product matches it.
  • Staff re-type the same data into three systems.
  • Per-user subscription fees now cost more each year than building your own.
  • Customers need to log in and serve themselves.

Working with us from anywhere in the UK or worldwide or worldwide

We are a UK software development company with people in London, and almost all of our work happens remotely. Scoping calls and progress reviews run on Google Meet, so a manufacturer in the Borders or a letting agent in Cornwall gets the same access to the developers as a firm down the road from us. If seeing your operation in person would help, we can arrange a visit.

Questions buyers ask

Straight answers. If yours is not here, email us.

How much does a web application cost in the UK?
With us, a first version with one core workflow, user accounts and an admin panel starts from £1,999. A multi-role product with an API and up to three integrations starts from £4,999, and larger platforms from £9,599. These are starting points. The price depends on your requirements, and you get a written proposal with the price and timeline after the first call.
How long does it take to build?
An MVP usually takes 4 to 5 weeks and a Product build 10 to 12 weeks. Those timelines assume the requirements are agreed up front and you can answer questions during the build.
What is the difference between a website and a web application?
A website shows information. A web application lets people log in and do something: book, order, approve, report. If you only need pages and a contact form, our website packages start at £499.
Can you take over or extend an application we already have?
Yes. We read the code first and tell you what state it is in. If it needs a clean-up before new features are safe to add, we say so before quoting.
What happens after launch?
MVP builds include 30 days of support and Product builds 60 days. After that, a monthly plan covers updates, fixes and small features: Care at £199, Growth at £599 or Scale at £999 a month.

Tell us what the software needs to do

Thirty minutes on a call is enough to know whether you need custom software and what it is likely to cost.
