It is necessary to send the costumer price (realized selling price), eventually reduced by discounts if agreed in the contract.

The realized selling price

The realized selling price equals the retail price of sale minus sales discount and incl. VAT. The price that is shown on the cash desk bill is meant. If an article will be sold at different prices (with or without discount), the article must be listed per price of sale as well.

The decimal delimiter can either be a comma or period.
