What needs to be provided in the VAT field when I'm creating an invoice?

Don't worry, you don't have to specify the VAT amount yourself.
Xolo will calculate VAT automatically. This is dependant on a variety of factors, including your business registration, what type of service you sell, your client's location, and their VAT payer status.

We’ll accurately calculate the VAT for cross-border sales transactions, too — which will make invoicing a lot easier!
