What we offer

When your work calls for a tool of its own, we build it from scratch: web apps that install on a phone like a native app (PWA), desktop tools, internal systems and admin panels. AI-assisted development lets us ship working products quickly across different languages and technologies.

When do you need custom software?

Packaged software covers general needs. When your business requires its own workflow, calculation or integration, you either force the package or bend your process to fit it. Custom software follows exactly your workflow, without unnecessary screens or costs. It isn’t always the right answer — if an off-the-shelf product will do, we say so.

What we build

  • Web applications and admin panels: internal systems for tracking requests, jobs, stock, subcontracting or projects.
  • Mobile apps (PWA): apps that install on the phone, work offline and run on Android and iOS from one codebase.
  • Desktop and local tools: tools that automate document generation, bulk processing and data transfers.
  • Integration layers: data flows between ERP, e-commerce, accounting and third-party services.

How the process works

A short business analysis defines the scope of the first release; we then work in milestones and collect your feedback at every step. Source code and documentation are handed over, and maintenance continues after launch. Examples: education solutions, digital startups.

What drives the price?

The number of screens and business rules, user roles, integrations, mobile/offline needs and hosting preferences. We choose between a fixed-scope proposal and a phased (sprint-based) model together.

FAQ

Questions about this service

Should I choose custom software or an off-the-shelf package?

If your process follows your industry’s standard flow, a package is usually faster and cheaper. If you need company-specific calculations, workflows or integrations, custom software is more efficient in the long run. We compare both options on cost and timeline in the first meeting.

Do you publish mobile apps on the app stores?

For most business apps we recommend a PWA, which doesn’t need the stores: one codebase, fast updates, lower cost. If deep device access or store visibility is required, we evaluate a native app.

Who owns the source code?

The source code and documentation of software built for you are handed over; usage and transfer terms are stated clearly in the contract.

Do you provide support after launch?

Yes. We offer monthly maintenance or on-demand support for bug fixes, security updates and new features.
