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
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.
Software vendors and mid-sized companies trust us









Every door leads to a clear first step: at a fixed price, with an honest recommendation.
My software has aged.
I need an app.
I want to automate documents.
Off-the-shelf software no longer fits.
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.
30 minutes to get to know each other: are we a fit? You talk to someone who understands your software.

from 498.00 €/month“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.”

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.
Who we work for and who we don’t →No stock imagery: this is us, in our offices in Bad Breisig.

Founder & Managing Director. In software development since 1997, specialized in .NET since 2002.

Software development team lead. He leads the technical delivery of your stages, from the first PoC to release.

Permanently employed, in Germany. Every product is delivered by André Krämer or one of our senior architects.
As a Microsoft MVP and book author, André regularly speaks at the major .NET conferences. Come by and ask your questions in person.
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.
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.
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.
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.
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.
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.
