Section 01

Why bespoke tools beat off-the-shelf software for a specific job

Every service business eventually hits the same wall. Off-the-shelf software solves 70% of a workflow and creates a workaround for the rest. Spreadsheets solve the last 30% and quietly become the single point of failure for the entire operation. A small, focused custom application solves the actual workflow — nothing more, nothing less.

The economics have changed. Modern low-code platforms and AI-assisted development mean the kind of internal tool that used to cost £30,000 from a traditional agency can now be built for a fraction of that. Project Pixel builds these tools with the same discipline as a website project: real scope, real timeline, real price.

Section 02

The kinds of applications Project Pixel builds

Not every idea needs to be a full SaaS product. Most engagements are smaller and sharper — a single workflow, a single audience, a single problem solved cleanly.

Client portals

Secure areas where customers can see project status, download documents, approve work, view invoices and message the team — instead of chasing everything by email.

Internal dashboards and lightweight CRM

A single view of leads, jobs, customers or projects tailored to how the business actually runs — not how a generic CRM assumes it should run.

Booking journeys and quote calculators

Guided, multi-step journeys that qualify a lead, produce a rough price or book a slot — turning a static contact form into a real sales tool.

Interactive lead-generation tools

Content-marketing assets with a job to do — checkers, calculators, mini-audits — that capture qualified enquiries in exchange for a useful answer.

Membership areas and resource hubs

Gated content, courses, downloads, directories or paid communities built around an existing audience.

Internal workflow apps and simple SaaS products

Larger builds with user roles, approvals, reporting and integrations — usually delivered as an MVP first, then extended based on real usage.

Section 03

How a Project Pixel app project runs

Custom software fails when scope is guessed. Project Pixel treats scope as its own deliverable — a paid discovery or planning stage sits at the front of any complex project. Once scope is real, the rest is straightforward.

1. Define the problem

Understand what the business is trying to make faster, clearer or easier — and who feels the pain today.

2. Scope the first version

Identify the smallest useful minimum viable product. Everything else becomes phase two.

3. Design the journey

User flows, screens, forms, permissions and data model — agreed on paper before code is written.

4. Build and test

Iterative build with regular review points, integrations to existing tools where required, and end-to-end testing of key workflows.

5. Launch and improve

Release the first version to real users, gather feedback, and prioritise the next phase against real usage rather than guesswork.

Section 04

How pricing works for custom applications

There is no single price for a web app because there is no single web app. A guided calculator is not a multi-user platform. Project Pixel prices every project against a written scope, and where scope is genuinely unclear, a paid discovery stage produces one.

Third-party software costs (hosting, email, payment processing, data services) sit outside the build price. Ongoing maintenance is optional and is agreed as a separate monthly arrangement where it makes sense.

Frequently asked questions

Answers to the questions we hear most often.

What technology does Project Pixel use to build apps?

A modern low-code and AI-assisted stack designed for fast, maintainable delivery. The specific tools are chosen to fit the project — the goal is a tool the business can actually keep using and extending, not a bespoke framework only one developer understands.

How much does a custom web app cost?

Tailored app projects start from £500. Real pricing depends on functionality — a single-purpose calculator sits at the low end, a multi-user internal platform sits much higher. Every project is quoted individually against a written scope.

Do I need to know exactly what I want first?

No. For anything beyond the simplest tools, a paid discovery or planning stage sits at the start of the project. That's where scope becomes real — before build time is committed.

Can Project Pixel integrate with existing systems?

Yes, where sensible. Common integrations include email, calendars, CRMs, payment processors and analytics. Complex enterprise integrations are reviewed as part of scoping.

Who owns the finished application?

The client owns the account, the data and the deployed application. Ongoing support is optional.
