When you have created an account with us, go to Settings → Cash book settings. By default, you will see the option 1 selected already, which states “Revenue categories”. There you can create all desired revenue groups.

You can choose whether to fill in the revenue groups every day, including or excluding VAT. It is therefore advisable to check what is on the Z report of your cash register (including or excluding) and to follow that. Be sure to select the correct VAT code for each revenue group!
