Custom Software
Custom software for processes that are too specific for an off-the-shelf product — almost always as a web application, from the data model to operations.
What it is — and what it includes.
Custom software is software tailored to a company’s processes — as opposed to off-the-shelf software, which makes processes adapt to its own rules. At Batunet, it is almost always built as a custom web application: used in the browser, with its own data model, roles and interfaces to existing systems. We build such systems where requirements are complex, business-critical and long-term.
Scope of services
- Requirements and domain analysis
- Architecture and data model
- Implementation as a web application with backend, frontend and APIs
- Development with tests and reviews
- Integration into existing systems
- Operations, maintenance and ongoing development
How we build. The Batunet Engineering Method.
Seven phases — from the first question to operations years later. Not a project process, but the way we think.
- 01
Frame
The actual problem, its boundaries and a measurable definition of success are established before any solution is considered.
- 02
Model
The domain is modeled and sliced into contexts — with a precise, shared language.
- 03
Decide
The load-bearing decisions come first — deliberately and documented, while change is still cheap.
- 04
Prove
A walking skeleton proves the architecture on the riskiest path — before going broad.
- 05
Build
On top of the proven skeleton, the system grows in verifiable, reversible steps — with progress visible every week.
- 06
Harden
Failure cases, load and security are tested, not assumed. “It runs” becomes “it holds.”
- 07
Operate
We operate, monitor and keep evolving the system — and keep it understandable and changeable.
What you can rely on.
- 01
A system that fits your processes — not the other way around
- 02
You own the source code and documentation of your system
- 03
A foundation that stays extensible for years

Questions about Custom Software
When does custom software pay off compared to off-the-shelf software?
When your process is a competitive advantage, no standard solution covers it, or customizing off-the-shelf software becomes more expensive than targeted custom development.
Do we own the source code?
Yes. The project-specific source code and the agreed project artifacts — documentation, configuration, migrations — are handed over to you. Open-source and third-party components used remain under their own licenses. You stay technically independent — including from us.
