I am wrestling with it now, because I cant justify spending 150EUR&#x2F;month _and_ 1500EUR at year end to keep books and file returns. I have but six to ten invoices a year, and only myself as an employee; but such an animal doesn&#x27;t seem very interesting to every relevant tax and accounting professional I&#x27;ve inquired with in Berlin. Perhaps it is the &quot;English&quot; premium, but at those costs I&#x27;m stuck spending more time than I care, at possibly greater risk than I am aware of, trying to do my own paperwork and books. In a system I mostly grok from (translated!) blog posts!
