What We Build

Tools and apps that make your business run smoother, convert more visitors, and save you time.

Pricing Calculators

Let customers estimate costs instantly. Mortgage calculators, cleaning quotes, insurance estimators — tailored to your pricing logic.

Booking Systems

Class scheduling, appointment booking, resource management — designed around how your business actually operates.

Lead Generation Tools

Interactive quizzes, assessment tools, and configurators that capture leads while providing genuine value to visitors.

Client Portals

Secure areas where your clients log in to view invoices, track projects, download documents, or manage their account.

Dashboards

Internal dashboards that pull data from your existing systems and present it in a way that actually helps you make decisions.

Quote Builders

Let customers configure exactly what they need and generate an instant quote — no back-and-forth emails required.

Why Businesses Are Ditching SaaS Tools

Here's a pattern we see constantly. A business signs up for a SaaS tool — a booking system, a CRM, a project management platform. It works fine at first. Then they hit a limitation. The tool doesn't handle their specific workflow. The pricing tier they need costs double. There's no way to export their data properly.

So they add another tool to fill the gap. And another. Before long, they're paying £300 a month across five different platforms, none of which talk to each other, and their team spends half their time copying data between them.

This is the SaaS trap, and more businesses are waking up to it. The tools are designed for everyone, which means they're perfect for no one. They're built around the vendor's idea of how your business should work, not how it actually works.

Custom-built alternatives solve this. One tool, designed around your exact process, that does exactly what you need. No features you don't use. No limitations you have to work around. No monthly fees that creep up every year.

The shift is accelerating because the cost of custom development has dropped dramatically. What used to take six months and £50,000 can now be built in weeks for a fraction of that. Modern frameworks, component libraries, and cloud infrastructure mean we can deliver production-quality tools at speeds that would have been impossible five years ago.

The Real Cost Comparison

Let's do the maths on a real scenario. Say you're using a SaaS booking and scheduling tool at £99 a month. That's £1,188 a year. Over three years — which is a conservative lifespan for any business tool — you've paid £3,564. And you still don't own anything. Cancel the subscription and it all disappears.

A custom-built booking system designed to your exact specifications typically costs between £2,000 and £5,000 as a one-off. After that, you own it. The only ongoing cost is hosting — usually around £10 to £20 a month. Over the same three years, your total cost is roughly £2,500 to £5,700.

So at worst, you break even. At best, you've saved over a thousand pounds and you own a tool that does exactly what you need instead of roughly what a SaaS vendor thinks you might need.

But the real saving isn't in subscription costs — it's in time. When a tool fits your workflow perfectly, you stop spending hours each week on workarounds. You stop training new staff on five different platforms. You stop losing leads because the form didn't capture the right information.

We've had clients tell us their custom tool paid for itself within the first month, purely through admin time saved. That's not marketing fluff — it's what happens when your tools actually fit how you work.

What We've Built — Real Examples

Instant quote calculator for a removals company. Their old process: customer calls, staff asks 15 questions, calculates a price manually, calls back the next day. New process: customer visits the website, enters pickup and delivery postcodes, selects property size and extras, gets an instant price. Enquiries increased by 40% in the first month because people could get answers at 11pm on a Sunday instead of waiting for office hours.

Client portal for a lettings agency. Landlords were constantly emailing for statements, maintenance updates, and inspection reports. We built a secure portal where landlords log in and see everything — financial statements, property photos, upcoming inspections, contractor invoices. The agency estimated it saved them 15 hours a week in back-and-forth emails.

Lead generation quiz for a kitchen designer. Instead of a generic "Get a quote" form, we built an interactive quiz: "What's your kitchen style?" Visitors answer six questions about their preferences, get a personalised recommendation, and are offered a free consultation. Conversion rate was 4x higher than the old contact form because people actually enjoyed using it.

Internal dashboard for a care company. Staff availability, shift patterns, client schedules, and compliance documents were spread across four different systems. We consolidated everything into one dashboard. Managers could see gaps in cover at a glance, compliance deadlines were flagged automatically, and the company passed their next CQC inspection with flying colours.

The Build Process, Step by Step

Step one: discovery call. We get on a call — usually 30 to 45 minutes — and you tell us what you need. We ask questions, challenge assumptions where needed, and by the end of the call we both have a clear picture of what we're building. No 10-page brief required. Just a conversation.

Step two: scope and quote. Within 24 hours, we send you a clear scope document and a fixed price. Not an estimate, not a range — a fixed price. It details exactly what we'll build, what's included, and the delivery timeline. If it's a simple tool, we're talking days. If it's more complex, maybe two to three weeks.

Step three: design. We create the visual design and user flow before writing any code. You see exactly what the finished product will look like. We iterate until you're happy — usually one or two rounds of feedback. This stage typically takes one to two days.

Step four: development. This is where the magic happens. We build your app using Next.js and React — modern, fast, and designed to scale. You get daily updates so you always know where things stand. No disappearing for weeks and hoping for the best.

Step five: testing and launch. We test everything thoroughly — different devices, different browsers, edge cases. When it's ready, we deploy it live, walk you through how it works, and make sure you're happy before we consider the project complete.

Step six: support. Every project includes 30 days of bug-fix support after launch. If something breaks, we fix it — no charge. After that, you can opt for an ongoing retainer or manage it yourself. No pressure either way.

Who Owns the Code?

You do. Completely. No strings attached.

When the project is delivered and paid for, we hand over the full source code. You can host it wherever you want, modify it however you like, and hire anyone you choose to work on it in the future. There are no licensing fees, no proprietary frameworks that lock you in, and no contracts that tie you to us.

This is a deliberate choice. We've seen too many businesses get burned by agencies that hold the code hostage — you want to leave, and suddenly there's a "migration fee" or the code is written in a proprietary system only they can maintain. That's not how we operate.

We build with open-source technologies that any competent team can pick up. Next.js, React, TypeScript, PostgreSQL — all industry standards. If you wanted to bring development in-house next year, your new team wouldn't need to learn a single proprietary tool.

What happens if you want changes later? You've got three options. First, come back to us — we already know the codebase and can make changes quickly. Second, hire someone else — the code is clean, documented, and built with standard tools, so anyone competent can jump in. Third, do it yourself — if you're technically inclined, the code is yours to modify.

Most of our clients stay with us because they want to, not because they have to. That's the way it should be. If you leave, you take everything with you. We'd rather earn your loyalty through good work than enforce it through lock-in.

Why Custom Beats Off-the-Shelf

SaaS tools charge you monthly forever and never quite fit. Custom tools cost once and work exactly how you need.
