Hello KlaudiaSobota,
Welcome to the community page,
Are you wanting to know how to record the delivery for the postage charge that is vat exempt in Quickbooks?
Are you wanting to know how to record this on the invoice?
If that is the case on the invoice you would have to do 2 lines. The first line would be the product and then the 2nd line will be the postage charge with the vat set to exempt.
