Thank you for your reply Moritz.
I don’t quite understand the state of the software. Generally, the actual version seems to be lacking many (basic) things and is quite buggy. We also tried to let the frontend show prices including tax, but even though the customer groups are correctly defined (brutto), it doesn’t work. We’ve encountered quite some limitations like these.
I guess my question is: version 6 doesn’t seem finished or usable for end user. Should we downgrade to Version 5 until everything is fixed? We absolutely lack the time (and skills) to help develop the app and don’t want to keep posting issues here.
What do you recommend we should do?
