Custom Software Development

The internal tool your business outgrew a spreadsheet for

Custom Software Development

Web applications, internal platforms, and customer portals built by a small senior team - shipped in increments you can use, not a big-bang launch a year from now.

Signs This Applies To You

If more than one of these sounds familiar, this is the right service to talk about.

A spreadsheet has quietly become a production system and people are afraid to touch it

Your licence fees are modest next to the cost of the workarounds built around them

Onboarding a new hire means teaching them a list of undocumented exceptions

A previous agency left a codebase nobody wants to open

You quote custom work by hand because no tool models the way you price

The Problem

Off-the-shelf software covers eighty percent of a business and the remaining twenty percent ends up in spreadsheets, shared inboxes, and one person’s head. That gap is where margin leaks and where onboarding a new hire takes six months.

Our Approach

We build the missing twenty percent as real software - versioned, tested, deployable - and we build it in slices so you are using something valuable long before the project is finished.

What The Work Covers

Internal operations tools

The admin panels, schedulers, and dashboards your team lives in, built around how the work actually flows rather than around a generic set of CRUD screens.

Customer-facing portals

Self-service accounts, order tracking, document exchange, and billing views that take routine questions out of your inbox.

Domain modelling

We model your entities, states, and rules explicitly, so business logic lives in one place instead of being scattered across conditionals and job titles.

Legacy replacement

Retiring an old system in stages: new capability moves to the new platform while the old one keeps running until it has nothing left to do.

Testing and delivery pipeline

Automated tests, a preview environment per branch, and one-command deploys from the first week rather than bolted on the month before launch.

How It Runs

01.Discovery sprint

Two weeks to pin down the domain model, the integrations, and the riskiest technical assumptions before anyone commits to a budget.

02.Architecture

We choose boring, well-supported technology and document why. No framework you will struggle to hire for in three years.

03.Incremental delivery

Two-week cycles, each ending with something deployed to a real environment that you can click through and react to.

04.Transition

You own the repository, the pipelines, and the infrastructure. We stay on for support only if you want us to.

Outcomes We Aim For

Working software in production inside a quarter

A codebase your own team can pick up and extend

Tests and CI/CD from the first commit, not retrofitted

When This Is Not The Right Fit

We would rather say so early than take the work and disappoint you later.

Problems an off-the-shelf tool already solves well - we will say so during discovery

Consumer apps chasing scale before a business model

Staff augmentation where you want bodies on a board rather than outcomes

Rewrites motivated only by the age of the current stack

In Practice

Where Custom Software Earns Its Keep

01.Quoting and pricing engine

A manufacturer whose quotes took two days and varied by estimator. The rules were encoded once, so quotes take minutes and margin is visible before the quote goes out.

02.Clinical scheduling platform

Rota, capacity, and compliance rules held in one system, with an audit trail detailed enough to survive an inspection.

03.Partner portal

Resellers self-serve orders, stock, and statements. Inbound account-management email fell away within a quarter of launch.

04.Spreadsheet retirement

A forty-tab planning workbook replaced with a small application that kept the same mental model, so the team did not have to relearn their own job.

Where We Have Done This

Healthcare

A scheduling platform that replaced eleven spreadsheets

Eleven clinics each ran their own rota spreadsheet. We built a single scheduling platform with the compliance rules encoded, not remembered.

Financial services

Document review cut from three days to under an hour

A lending team read every application pack by hand. We built an extraction and classification workflow with a human review queue, benchmarked on two years of their own files.

Questions

Custom Software Questions We Get Asked

Discovery is a fixed fee. After that each phase is fixed-scope and fixed-price, quoted from a plan you have read. Most first projects land between $40k and $150k depending on scope.

They usually do. Phases are two weeks long, so a change waits days rather than months, and re-scoping affects the next phase instead of voiding the arrangement.

You do, from the first commit. Repositories sit in your organisation, cloud accounts are yours, and there is no proprietary runtime you have to keep paying us for.

Yes, and it is often the best arrangement. We can lead a workstream, pair to transfer knowledge, or take one area such as infrastructure while your team stays on product.

You either take it in-house with a documented handover or keep us on a support retainer. Both are normal, and we do not price the handover to punish the first option.
