After I unfortunately had negative service experiences with other employees due to rescheduled appointments and unreliable processes, Franziska made up for a lot with her friendly manner and sound expertise during the consultation, and I felt very well looked after by her and found her support extremely helpful. Thank you very much!

The data is prepared individually from the accountant's point of view. If there are problems with the account assignment or posting keys, we respond immediately. Many thanks for the competent support. LG from the tax office
