How is the net invoice amount calculated toward the period target?

The net invoice amount is calculated by excluding discounts and VAT:

• For tax-exclusive pricing (tax added on top):
  • Net Amount = Invoice Total excluding tax − Discounts
• For tax-inclusive pricing (tax included in the price):
  • Net Amount = Invoice Total − Discounts − VAT

The contribution percentage is then applied to the net amount, and only the resulting value is added toward target achievement. What counts toward the target is the net sales value — regardless of whether the tax is added on top of the price or included within it.
