Despite I found many discussion about it a can't understand IF and HOW I can achieve the following taxation schema:
-----------------------------------------------------------------------------------
Service 1: €1500.00
Insurance compensation (4% of Service 1): €60.00
---------
Subtotal 1 (Service1 + Insurance compensation): €1560.00
VAT (21% applied to Subtotal1): €327.60
Invoice total (Subtotal1 + VAT): €1887.60
---------
Witholding TAX (20% of Subtotal1): - €312.00
---------
Net Pay (Invoice total - Witholding tax): €1576.60
My conclusion is that is not possible, and that ZOHO Invoice is still not ready for our market, but I will gladly change my mind if you can show me how I can do it... ;-)
