If your customer is a company, the invoice price is usually agreed to be VAT0% and VAT is added to this price which your customer can deduct as such in their own taxation. When entering your invoicing price, you must mention that the price is 0% VAT and VAT will be added to it. FREE! will deliver VAT on your behalf to the tax authorities and you do not have to worry about that. If your customer is a private individual, you must indicate the final invoicing price, including VAT.
