Custom Software Development

Systems built for how your business actually works.

What’s included

  • Internal operations platforms
  • ERP and CRM extensions
  • Data platforms and reporting
  • System integrations and middleware
  • Legacy system modernisation
  • APIs and developer tooling

Overview

Custom software is the right answer less often than vendors suggest, and more often than boards assume. It is justified when the process is a genuine competitive difference, when licence costs scale worse than build costs, or when the workaround spreadsheet has quietly become the system of record.

We will tell you which of those applies to you. When custom is not warranted, we say so and help you configure what you already own — that answer has cost us projects and kept clients for years.

Deliverables

  • 01Requirements and domain model
  • 02Technical architecture and integration plan
  • 03Production system with admin tooling
  • 04Automated tests on critical paths
  • 05Deployment pipeline and monitoring
  • 06Documentation and team enablement

Business outcomes

  • The process, modelled correctly

    Software that matches your approvals, pricing rules and exceptions instead of forcing a generic workflow onto your team.

  • One source of truth

    Integrations that end the reconciliation meeting, because the numbers in three systems finally come from one.

  • Maintainable after we leave

    Typed codebases, tests on the paths that matter, and documentation written for the developer who inherits it.

Typical stack

TypeScript · Node.js · Python · PostgreSQL · Redis · Docker · AWS · Terraform · GitHub Actions

How we deliver it

  1. 01

    Problem

    What is this actually costing you today?

    Custom software is justified when the process is a real competitive difference, when licence costs scale worse than build costs, or when a workaround spreadsheet has quietly become your system of record. We start by testing which of those is true — and if none of them are, we say so.

    • The measurable cost of the current process — hours, errors, lost revenue
    • Who is affected, and what they do instead when the system fails them
    • Whether configuring what you already own would solve most of it
    • The commercial outcome this project has to move

    What you get

    A written problem statement and the success criteria you can hold us to.

  2. 02

    Discovery

    How does the work really happen, not how is it documented?

    We sit with the people doing the job and map what they actually do, including the exceptions nobody wrote down. Those exceptions are usually where the project succeeds or fails, because they are what the off-the-shelf tool could not handle.

    • Stakeholder interviews and a walkthrough of the current process
    • Review of existing systems, data quality and integration constraints
    • The edge cases and exceptions that generic tools cannot model
    • Scope split into phases, ordered by value and risk

    What you get

    A process map, a phased scope and a written estimate per phase.

  3. 03

    Solution

    What is the smallest version that actually solves it?

    We design the flows before writing code, and validate them with the people who will use them daily. Expensive assumptions should fail in a prototype, not in production six months later.

    • User flows and information architecture for the critical paths
    • An interactive prototype tested with real users
    • Explicit decisions on what is out of scope for phase one
    • Trade-offs stated in writing, with their cost

    What you get

    A prototype you can click through and sign off with confidence.

  4. 04

    Architecture

    Will this still hold at ten times the load?

    Data model, permission model and integration boundaries are structural decisions — changing them later means touching every query and every screen. We make them deliberately, write down the reasoning, and design for the tenth-thousandth record rather than the tenth.

    • Domain and data model, with growth and reporting in mind
    • Permissions modelled as policy, not checked ad hoc per endpoint
    • Integration boundaries and failure behaviour for each dependency
    • Hosting, data residency and cost profile agreed up front

    What you get

    An architecture decision record — what we chose, what we rejected and why.

  5. 05

    Development

    Can you see it working, or only read that it is?

    Two-week increments, each ending in working software on a staging environment you can use. Progress is something you try, not a percentage in a status report.

    • A staging environment you can use from the first sprint
    • Code review, typed codebases and tests on the paths that matter
    • A short written update every week — progress, risks, decisions needed
    • Change requests priced openly rather than absorbed until the date slips

    What you get

    Software you can try every two weeks, not a status report you have to trust.

  6. 06

    Launch

    What happens if something goes wrong at 9am on day one?

    A launch should be an event on the calendar, not a gamble. We plan migration, rollback and the first week of support before the date, and we agree who is on call and how fast they answer.

    • Data migration rehearsed on a copy before the real run
    • A rollback plan that has been tested, not just written
    • Functional, cross-browser, performance and accessibility verification
    • Training and documentation for the people who will use it daily

    What you get

    A launch with a tested rollback and a named person answering during the first week.

  7. 07

    Support

    Who keeps this working in two years?

    The version that ships is the first version. What matters afterwards is whether the system can be handed to someone else — so we document for the developer who inherits it, and you can keep us, replace us or take it in-house without a rewrite.

    • Monitoring, error alerting and an agreed response window
    • Analytics reviewed against the success criteria set in stage one
    • Dependency, security and platform updates on a schedule
    • A prioritised roadmap for the next funded increment

    What you get

    A system that keeps improving against numbers you agreed at the start.

Frequently asked questions

Service FAQ

Usually one of three things is true: the process is a genuine competitive difference, licence costs are scaling worse than a build would, or a spreadsheet has become the system of record. If none of them are true, configuring what you already own is cheaper and we will tell you that — it has cost us projects and kept clients for years.

There is a full walkthrough on our custom software development page — problem, discovery, solution, architecture, development, launch and support, with what you get at the end of each stage. This page covers what we build; that one covers how a project runs.

Yes. We start with a paid technical audit: what works, what is risky, what it would cost to stabilise versus rebuild. You get that assessment as a document you can act on with or without us.

By writing scope as user-visible outcomes with acceptance criteria, and by pricing change requests transparently rather than absorbing them silently until the timeline slips.

That is our dedicated team model: named engineers, your backlog, your ceremonies, billed monthly. It suits work where priorities move faster than a fixed scope can be written.
