If you raise a sales invoice but need to charge the client for expenses incurred, and you are vat registered, do you charge vat for the expenses line? And if so, is it the gross amount that you add vat on?
As depends if is a disbursement or recharge whether you add VAT or not.
Up to you whether is the net or gross you add VAT too though expect your customer will only pay the same as you have paid out so therefore would be the net.
