Invoice

An invoice is an accounting document recording a supply and the amount due for it. It identifies the goods or services, the parties and relevant amounts. Dutch invoicing requirements specify necessary information, with different cases and exceptions.[1] An invoice alone does not prove that payment has been received.

Link it to the relevant order and check quantities, prices and tax treatment before issuing it. Keep corrections traceable to the original document. Track invoice status separately from payment status: a sent or posted invoice may remain unpaid, disputed or only partly settled.
