09 / CUSTOM SOFTWARE

Custom software shaped around your business, data and constraints

From discovery and architecture to tested releases, documentation and a support plan—using only the technology the product needs.

WHO IT IS FOR

For organisations connecting several systems or building a digital product that standard software cannot support.

OUR APPROACH

Define the outcome, scope and acceptance criteria before choosing technology, so the investment solves a real problem and remains maintainable.

PROBLEM

Problems to solve before adding another tool.

OUTCOME

What the project should make better.

  • Architecture aligned with risk and budget
  • A release roadmap with acceptance criteria
  • A testable and observable system
  • Clear documentation and ownership
USE CASES

Useful scopes shaped around the work.

01

System Integration

Connect APIs and data with validation, retries and audit history.

02

Business Platform

Bring critical workflows into a role-aware system.

03

Digital Product MVP

Prove product value through a measurable first release.

04

Legacy Modernisation

Isolate risk and migrate without stopping everything at once.

SYSTEM THINKING

From workflow to an application that can be accepted

Connections, permissions and failure states are designed alongside the interface, so a simple front end does not hide operational risk.

DELIVERABLES

Deliverables that can be accepted and operated.

01

Technical discovery

02

Architecture and delivery roadmap

03

Product and interface design

04

Incremental development and QA

05

Operational documentation and support plan

SCOPE & INVESTMENT

Project scope and pricing inputs

Scope follows uncertainty, integration risk, data, security and long-term operation. Screen count alone is not a meaningful estimate.

  • Scope and uncertainty
  • Integrations and migration
  • Security and compliance
  • Support and release model
ACCEPTANCE & OPERATION

Acceptance and operating costs

Project acceptance criteria

  • Agree API contracts and test failure cases
  • Test permissions, migration and the agreed rollback plan
  • Hand over source, deployment documentation and account ownership

Ongoing costs to itemise in the proposal

  • Domain, hosting and the chosen CMS
  • Content, dependency and integration maintenance
  • Monitoring, backups and scoped support

Test coverage and operating responsibilities are agreed for the project before work begins.

From scope to acceptance and handover

01 /

Understand

Discuss goals, audiences and constraints to define a useful scope.

02 /

Design

Make structure and interactions clear before development begins.

03 /

Build & test

Develop the system and test critical journeys across real devices.

04 /

Launch & support

Launch, share documentation and use evidence to guide improvements.

Agree test cases, reviewers, account ownership and support before work. Test critical journeys with approved data before launch.

FAQ

Questions before the work begins.

Should we use standard software or build?

If an existing product meets most needs and process adaptation is inexpensive, it is often the better choice. Custom software is justified when the difference matters materially.

Can you take over an existing system?

Review source code, account access, data, deployment and integrations before choosing to improve the current system, add an API or replace a specific part. Agree backup, testing and rollback before migration. Feasibility and cost depend on examining the actual system.

Can delivery be phased?

Yes. We prefer phases that release a complete workflow or outcome rather than splitting only by technical layer.
