For owner-led software vendors & mid-sized companies

Your software has proven itself.
We reimagine it, instead of just porting it.

Your industry solution has been earning money for decades, but WinForms, the .NET Framework and the desktop are holding it back. We modernize step by step with web, cloud and AI: evolution instead of revolution. Every stage delivers something you can sell to your customers. That way the modernization pays for itself.

Four doors, one journey

What describes your situation?

Every door leads to a clear first step: at a fixed price, with an honest recommendation.

My software has aged.

  • New features take months, maintenance eats up the budget
  • The knowledge sits in a few heads, and those people will move on eventually
  • Your customers expect web and cloud, your solution is desktop

I need an app.

  • Field staff, drivers or production still work on paper
  • Data gets typed up in the evening instead of captured on the spot
  • Your existing app has aged technically

How we work

Whichever door you come through: the journey is the same.

No project blind flight, no big bang. From the free first call to ongoing support: every step is bookable on its own, and each one is credited toward the next.

First call

30 minutes to get to know each other: are we a fit? You talk to someone who understands your software.

free & without obligation

Compass

Your strategy session: a questionnaire up front, then 90 minutes with an architect. Where do you stand, what is the right path? With an honest recommendation, even if it is “not us”.

499.00–749.00 € · with results guarantee

Roadmap

A workshop on architecture and processes, and for the legacy workshop on your business model too (license or subscription?). The result: a prioritized roadmap in stages.

3,999.00–7,499.00 € · fixed price

Delivery in stages

We modernize for you, stage by stage. Each one ends with working software that brings value to your customers. You can exit after every stage, with no loose ends.

Sparring or maintenance

Afterwards you choose: your team does it and we accompany them (sparring), or we keep everything running (maintenance contract).

Proof, not promises

First the migration tool failed.
Then came the software, reimagined.

ODYSYS – industry solution for heavy-load rental

  • The attempt to move the desktop software to the web with a migration tool failed.
  • With us it was reimagined: processes instead of paper forms, Blazor instead of WinForms, AI-supported, stage by stage.
  • A long-term partnership: from the first architecture sparring through the PoC to ongoing development, on board for years.
“With Quality Bytes we had a partner who was technically deep in the matter, who thought along with us and stayed on board after the release.”

The custom software became so good that our customer founded their own company to license it as an industry solution. Software that creates enterprise value. Literally.

Cadosys

Started with a training. Today two of our developers are continuously migrating the legacy desktop application to Blazor. A small entry point, a lot of trust.

“Quality Bytes understood our requirements from the very start and has been reliably developing the app with us since 2019.” – Jendrik Schneider, Managing Director

Honestly

We are not the right partner for everyone.

If you want to move your software from old to new as quickly and 1:1 as possible, without changing anything about processes or business model, then a migration tool like Wisej serves you better and cheaper. We will tell you that in the first call too.

We are the right ones if you see modernization as an opportunity: rethinking processes, reviewing the business model (license or subscription?), turning the software into a growth driver.

Frequently asked questions

Answered clearly.

What does it cost to modernize a WinForms application?

The honest answer: it depends on the scope. That is why we do not sell a flat rate, but stages. The entry point, however, is always a fixed price: the Legacy Future-Check costs 749.00 €, the Modernization Report 3,499.00 €, the two-day strategy workshop 7,499.00 € (all net plus VAT, credited toward each other). After that you know your roadmap including an effort estimate and decide anew after every stage.

Do we have to rewrite our software completely?

No. The big-bang rewrite is one of the most common mistakes we see. We modernize step by step: the new web application grows module by module and calls the old application for the parts still missing. Your customers only notice the improvements from the rebuild.

What if we simply want a quick 1:1 migration?

Then we are not the right partner. There are migration tools like Wisej that can do that more cheaply. We are the right ones if you want to rethink processes and business model, instead of preserving a 20-year-old interface in new technology.

Do you work together with our existing development team?

Yes, in two ways. Either we do the work and your team learns along the way (know-how transfer is part of every stage), or your team modernizes itself and our architects accompany them in sparring, in three tiers: 999.00 €, 1,999.00 € or 2,999.00 € per month.

What risk are we taking?

A deliberately small one. The orientation products come with a results guarantee: a clear recommendation or you pay nothing. You buy the delivery in stages: after every stage you have working software and can exit, with no loose ends. And every step is credited toward the next.

The first step

Ready for 30 minutes that create clarity?

30 minutes, free, no obligation. You talk to someone who understands your software. In the end you will know whether we are the right ones for your project. If not, we will tell you openly.
