Invoice refers to the business vouchers issued and collected by all units and individuals in buying and selling goods, providing or receiving services and engaging in other business activities. It is the original basis of accounting and an important basis for law enforcement inspection by audit institutions and tax authorities. The receipt is the proof of receipt and payment, and the invoice can only prove that the business has happened, but can't prove whether the money has been received or paid.
