how do revisions work?
Every package includes 1–3 rounds of revisions, agreed upfront. Bigger scope changes are quoted separately.
what do you need from me to start?
Access to your existing systems if relevant, plus one point of contact who can approve decisions.
what if i'm not happy with the result?
You're covered by our 7-day satisfaction guarantee — see the details on our Refund Policy.
do you work with clients outside germany?
Yes — everything is delivered digitally, so we work with businesses across Europe and beyond, entirely online.
The people behind WebLogicSysx.
WebLogicSysx started the way most honest studios do: with one too many bloated agency invoices and a better way of working sketched on the back of an envelope. Founder Bert Krupski had spent years building systems inside larger teams and kept seeing the same thing — clients paying for process, not progress.
We build the way we'd want to buy: scoped clearly, priced honestly, and handed over in a state you can actually maintain without calling us back every week.
We're based in Elmshorn, and most of our work never sets foot in an office — we build for businesses across Germany and further afield, entirely online, start to finish.

"I still write the first line of every project myself."

"If it can't survive a traffic spike, it's not finished."

"Deployments should be boring. That's the whole job."
What clients say once the deploy is done.
"They shipped our API integration ahead of schedule, zero downtime."
