Software Built Around Your Business, Not the Other Way Round

When the process that makes you money doesn't fit anything you can buy, we build the system that runs it — and hand it over documented enough to outlive us.

  • Architecture before code
  • Test coverage from day one
  • You own the source outright
  • Handover your team can act on

Is this you?

Four Signs You've Outgrown Off-the-Shelf

Every one of these has a cost attached, and it usually shows up as headcount rather than a line item.

  • Your process lives in spreadsheets and people's heads

    The business runs on files nobody owns, rules nobody wrote down, and one person who understands the whole thing.

  • You're paying for software you work around

    Per-seat licences for a tool that does 70% of the job, plus manual effort to bridge the rest.

  • The system that runs the business is fifteen years old

    It works, nobody dares touch it, and the people who wrote it left a long time ago.

  • Your systems don't talk to each other

    The same data gets keyed into three places, disagrees between them, and someone reconciles it by hand each month.

Overview

Custom Systems, Built to Be Owned

The architecture decisions get made deliberately, before they become expensive to reverse.

Custom software is the right answer less often than agencies like to suggest — and exactly right when the thing you do differently is the thing that makes you money. If your pricing, your workflow or your compliance obligations don't fit anything on the market, working around a product forever costs more than building the system once and owning it.

We start by mapping the process rather than the software: who does what, in what order, with which exceptions, and where the current version leaks time or accuracy. That mapping is what produces a sane data model, and the data model is the decision that's hardest to change later. Then architecture — services, integrations, deployment topology, failure modes — agreed and written down before anyone opens an editor.

From there we build in two-week sprints with tests written alongside features, not after them. You see working software early and steer continuously. And because the system will outlive the engagement, we treat documentation, deployment pipelines and handover as deliverables rather than courtesies: your team should be able to run, extend and hire for this without us.

Capabilities

What's Included

Nine areas of systems work. Most engagements use half of them; the discovery decides which.

  • Business Systems

    Line-of-business platforms that run operations, quoting, scheduling, compliance or fulfilment the way your business actually does them.

  • Internal Tools & Admin Platforms

    Back-office interfaces with role-based permissions, giving each team exactly the data and controls they need and nothing they don't.

  • Legacy Modernisation

    Ageing systems documented, de-risked and replaced incrementally — strangler-fig rather than a big-bang rewrite nobody survives.

  • System Architecture

    Service boundaries, data models, queues and deployment topology designed against your real load and your real failure modes.

  • Data Modelling & Migration

    Schemas that survive growth, plus migration of historical data with reconciliation you can actually verify.

  • Systems Integration

    ERP, CRM, finance and logistics systems connected through documented, resilient layers rather than brittle point-to-point scripts.

  • Automation & Workflow Engines

    Rules, approvals and scheduled jobs that take the repetitive parts of a process off people entirely.

  • Reporting & Analytics

    Operational reporting built on the same model as the system, so the numbers in the dashboard match the numbers in the database.

  • Security & Compliance

    Authentication, audit trails, data retention and access control built to meet the obligations your sector actually imposes.

Our Process

How We Build a System

Six phases. The expensive decisions are made in the first two, deliberately.

  • 01

    Discovery & Process Mapping

    We map the process as it runs today — including the exceptions people handle informally — and agree what success looks like in numbers rather than adjectives.

    Deliverables: Requirements document, process maps, success metrics

    1–2 weeks
  • 02

    Architecture & Data Model

    Service structure, database schema, integration contracts and deployment topology designed and documented before development, because these are the decisions you can't cheaply undo.

    Deliverables: Architecture diagram, data model, integration contracts, sprint plan

    1–2 weeks
  • 03

    Interface Design & Prototyping

    The screens people will live in daily, prototyped and put in front of them before they exist in code. Internal tools fail on usability more often than on function.

    Deliverables: UI designs, clickable prototype, component specifications

    2–3 weeks
  • 04

    Development & Testing

    Two-week sprints, each ending with working software you can use. Unit, integration and performance tests written alongside features rather than bolted on.

    Deliverables: Working builds every sprint, test reports, sprint review notes

    6–14 weeks
  • 05

    Deployment & Rollout

    Infrastructure, data migration, security review and a staged rollout — usually running alongside the old system until the numbers reconcile.

    Deliverables: Production deployment, migration reconciliation, runbook

    1–2 weeks
  • 06

    Support & Iteration

    Monitoring, issue resolution and enhancement work prioritised by what users actually do rather than what the original spec assumed.

    Deliverables: Support reports, performance analytics, roadmap recommendations

    Ongoing

Engagement

How We Work Together

Three shapes, depending on how settled the requirements are and who owns the roadmap.

  • Defined feature set, agreed timeline, fixed price. Best when the process is well understood and the destination is known.

Fit

Who This Is For

And, just as usefully, who it isn't for.

Ideal for

  • Businesses whose core process doesn't fit anything on the market
  • Operations teams running critical work through spreadsheets and email
  • Companies carrying a legacy system nobody wants to touch
  • Organisations paying per seat for software they substantially work around
  • Regulated businesses needing audit trails and provable access control
  • Teams that want to own the platform their business depends on

Not the right fit if

Why DM Solutions

What You Get Beyond the Code

Four commitments aimed at the second year of ownership, not just the launch.

  • Architecture Before Code

    The data model and service boundaries get decided deliberately, in writing. These are the choices that decide what the system costs to change three years from now.

  • Testing Is Not Optional

    Unit, integration and performance tests are part of every project — not a line item that gets cut when the timeline tightens.

  • Documented for Handover

    Architecture notes, schema, API docs and a runbook, written as we go. Your team should be able to hire against this system without talking to us.

  • We Say No to Building It

    If an off-the-shelf product would do the job, we'll tell you which one. Custom software you didn't need is the most expensive thing we could sell you.

Proof of work

Systems Still Running Years Later

Builds where the process got measurably faster, cheaper or more accurate — and stayed that way.

Questions

Frequently Asked Questions

The six that come up before every custom build.

  • Add up what the workarounds cost — licences for tools you half-use, hours spent rekeying data, errors that reach customers, and the risk concentrated in one person who understands the process. If that total is smaller than a build, buy something. If it isn't, and the process is genuinely a competitive advantage, build it. We'll help you do that arithmetic honestly.
