You can now set non-deductible VAT as default in the sheet of suppliers. This sets the VAT field to 0. The VAT will be added to the price excluding VAT, because in many cases it can still be entered as a professional cost. For more information about non-deductible VAT and percentage of professional expenses, please contact your accountant.
To set the option for a particular supplier, open the supplier sheet by clicking on the name of supplier in the menu 'Suppliers'. Then tick the checkbox next to the item 'VAT non-deductible'. Don't forget to save your changes afterwards.
