I too would like to know how to display different item tax rates on the same invoice.
For example, Item A is sold to customer at my shop in City A at 5% sales tax rate
Item B is sold to same customer, at their house, in City B at 6% sales tax rate
Invoice should show separate item tax for Item A and Item B
The invoiceplane software allows me to select different tax rates for different items while creating the invoice, but when the PDF is generated, it adds all the tax together without displaying the individual item tax applied to each item.
