If set-up in the account, taxes and discounts may be visible in documents that include the product value/price column (sales quotes, orders and invoices) and can be selectable when such a document is created. An example may be a 20% VAT (value added tax) or a 30% summer clearance (discount). Taxes do not get calculated in product costs and revenues. Discounts do get calculated in product costs and revenues. When creating a document, a tax or a discount may be automatically (without manual user interaction) selected by the system, if they are set in a pricing rule and that pricing rule applies to the document when the document is created.
