VAT
What
If your organization works with different VAT rates, these can be defined here.
A 0 percent VAT must be set up. This VAT is used for surcharges that are not VAT-relevant.
When you later create products, offers and more or simply manage prices, you will find a mandatory field where you must assign the prices to a predefined VAT.
So the ID is predefined by the accounting system. As we can link advatra to the accounting system, in this case the booking is automated if the ID is entered correctly in the VAT.
