All websites and shops are in wordpress. I need software to make my bookkeeping for each holiday house separate and for each online shop separate. This all in one software. Of course flexible to set in future more possibilities. I have a german bank account and three czech bank accounts. To make the work for bookkeeping easier it should be with import and export possibility for csv and excel sheets. Also to make charts for each online shop or holiday houses. The documents for bookkeeping are in pdf and should be there Managed to every booking.
