Krafteq for Düsseldorf — across the Rhine in 30 minutes

Our office sits about 25 kilometres south of Düsseldorf's old town — via the A59 or A57 you reach us in around 30 minutes, and we reach you just as quickly. Direct technical contact instead of a call centre, plain language, on-site meetings whenever it makes sense.

Krafteq is based in Leverkusen, roughly 25 kilometres south of central Düsseldorf. Via A59, A57 or A52 we are at your door in 25 to 35 minutes — whether you are in Pempelfort, Bilk, Flingern or at the Medienhafen.

For trades and small businesses in Düsseldorf

Düsseldorf is more than Königsallee, Medienhafen and corporate headquarters — its trades and small business sector is unusually strong, especially in the period-building districts around Pempelfort, Flingern, Bilk and Oberkassel. These are the businesses we typically serve:

Carpentry and renovation in Pempelfort and Flingern

Carpenters, joiners and interior fitters focused on high-end period-building renovation — job management, on-site measurement, material planning and invoicing with XRechnung in software that fits the way you actually work.

Plumbing, heating and electrical in Bilk and Friedrichstadt

SHK and electrical contractors with a mix of private and commercial work. Maintenance contracts, fault tickets, technician dispatch and mobile site capture — as your own software, not as a subscription.

Painters and floor layers across greater Düsseldorf

Painters, decorators and floor layers with 1–20 employees in the Düsseldorf area. Quoting, measurement, photo documentation, invoicing — all in one software that does not get more expensive every year.

Roofers and façade contractors in Oberkassel and Düsseltal

Roofers, carpenters and façade specialists serving the demanding clientele on the left bank of the Rhine. Specific quoting models, photo measurement, site logbook — built precisely for your business.

Small agencies and service businesses at the Medienhafen

Advertising, event and communication agencies with 5–20 staff. Project management, time tracking, invoicing — as your own software, no monthly subscription, with DATEV or Lexoffice integration.

Owner-led businesses in Gerresheim, Eller and Lierenfeld

Classic right-bank Düsseldorf trades — building sub-contractors, metalwork, automotive workshops. Your processes have grown over years; off-the-shelf subscription software rarely fits. Your own software reflects how you actually work.
