I look forward to hearing from you!

Is collaboration suitable?

Working together is possible if you…

  • are willing to work digitally and paperless
  • value clear structures, transparency, and reliability

Who I am currently unable to take on:

  • Cash-intensive businesses
  • Online shops (e-commerce) / influencers
  • Clients who still want to work predominantly with paper


Important note:
After receiving your request, I will check whether collaboration is possible and get back to you within two to three business days.

Submitting the form does not constitute an order. An order must always be agreed explicitly in writing.

Your contact person

Marcus Kather, M.A., Steuerberater (Certified German Tax advisor)

E-Mail: info@stb.kather.de
Appointment by arrangement—by phone or video call

The online appointment calendar is intended exclusively for existing clients. You can find the link here and in my email signature.
