Services Custom software

Custom web and mobile software, built around your workflows.

Whether you are launching a new product or replacing a system you have outgrown, we take it from first scope to a maintained release. We start with the people using the software, then build the interfaces, APIs and infrastructure around them.

What you get

A scoped first release

We map the core journeys, choose the first useful release, and turn requirements into a practical plan.

Web, mobile and API development

Interfaces and backend services that share the same APIs, so your web app, mobile app and internal tools work from the same data.

A tested, documented handover

Access rules, tests for the important workflows, and documentation of the decisions your team needs after launch.

What we’ll clarify in discovery

We use the free discovery call to work through these questions with you.

  • Who uses the product and what must they accomplish?

    We map the people using the product, the tasks they need to complete, and what a successful journey looks like. Those journeys guide the scope and interface decisions.

  • Which existing systems and data need to connect?

    We review the relevant tools, data owners and handoffs with your team to identify the integrations, access rules and data constraints the product must support.

  • What belongs in the first release, and what can follow?

    We compare priorities, dependencies and delivery constraints to define a useful first release, and separate essential journeys from improvements that can follow after feedback.

How a project runs

From the first call to a working release, with a clear next step at every stage.

01Discover

Free 30-minute discovery call

Tell us about your goals, users, current systems and constraints. We suggest a sensible first step, with no obligation.

02Scope

Scope and estimate

We agree on a focused first release, with priorities, milestones and an estimate you can plan around.

03Build

Build with regular demos

You see working software early and often, so decisions stay grounded in what you can use.

04Release

First release in 4–8 weeks

A focused first release typically ships within that window. Larger systems such as ERP platforms ship in phases, followed by ongoing support.
