General VAT settings
Faktum Invoicing supports three main VAT modes: Net, Gross and No VAT. When you use the Net mode, all prices are specified without VAT. If you change to Gross, all prices specified are including VAT. As the name says, No VAT will completely disable the VAT functionality.
The global default values for this is specified under VAT -> Defaults.
If you want to change these values for a specific customer, you can do that under Customers -> Defaults.
When you create a document, the used VAT Zone will be the zone defined under delivery address. If delivery address is not specified, the VAT zone of the billing address will be used.
Please note that any change done to the VAT Defaults will only apply for new documents. Existing documents will not be changed.
