What We Build
Know exactly what you’re getting
Every project starts with a written scope, so there are no surprises halfway through the build. If a detail isn’t covered, we confirm it in writing before development begins.
- Feature list, milestones and timeline agreed before the first line of code.
- Technology stack, target Windows versions and system requirements stated up front.
- You own the source code and the build, handed over on delivery.
- Support and maintenance terms agreed alongside the build, not after it.

Why teams choose DevSource
Built around your workflow
We start from how your team already works, then build the software around it — rather than forcing your process into an off-the-shelf tool that almost fits.
Clean, maintainable code
Readable structure, documented setup and a repository you own. Whoever picks the project up next — us or your own team — can work in it without a rewrite.
Automation-first approach
Before adding a screen, we ask whether the step needs a human at all. The repetitive parts of your process are the first thing we look to remove.
DevSource is an independent software development studio. Product and technology names referenced on this site belong to their respective owners and do not imply affiliation or endorsement.
Reliable software, practical solutions, built for your workflow.
No boilerplate, no resold templates. Every project is scoped, built and tested for the business that commissioned it.

We define the features, technology and approach, then agree scope and timeline in writing.
03
Build & test
Development runs in milestones you can review, with testing on the target Windows environment.
04
Deliver & support
You get the application, the installer and the source. Ongoing support is available when you need it.

Have a desktop software idea?
Let’s turn it into a working application. Tell us the problem and we’ll come back with an approach, a scope and a timeline.
Every project is quoted individually — there are no fixed packages, because scope and timeline depend on what the software has to do. You receive a written quote before any work starts, and payment is requested afterwards as a secure Stripe invoice.
FAQ
Questions answered.
Still curious? Email us and a developer replies within one business day.
Talk to a developerWhat kind of software do you build?
Custom Windows desktop applications: business management tools, internal dashboards, data processing and reporting software, automation utilities and applications that integrate with existing systems and APIs.
How does a project start?
Send a short description of the problem or workflow. We come back with questions, a proposed approach, a scope and a timeline — before any development is commissioned.
How long does a project take?
It depends entirely on scope. A focused automation tool can be days; a full business application is measured in weeks. You get an estimate in writing as part of the scoping step.
How much does it cost?
Pricing is quoted per project once the scope is defined, so you know the cost before work begins. Larger builds can be split into milestones with payment per milestone.
Do I own the source code?
Yes. On delivery you receive the application, the installer and the full source code. The project is yours to maintain, extend or hand to another developer.
Can you work with an application we already have?
Yes. We take on modernization work — adding features, fixing defects, redesigning the interface, or migrating an older application to a current framework.
Which technologies do you use?
Most often C# and .NET for Windows desktop applications, Python for automation, and Electron with TypeScript or React where a cross-platform interface makes more sense. The stack is chosen to fit the problem.
Do you provide support after delivery?
Yes. Support and maintenance terms are agreed alongside the build. That can be ad-hoc fixes or an ongoing arrangement, depending on what the application needs.
