Electronic invoice is the product of the information age. Like ordinary invoices, they are distributed to merchants in the form of unified issuance by the tax bureau. The invoice number is distributed to merchants with national unified coding and unified anti-counterfeiting technology.

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 it is also an important basis for law enforcement inspection by audit institutions and tax authorities. Receipt is the proof of receipt and payment, and invoice can only prove that the business has happened, but can't prove whether the money has been received or paid.

Invoice refers to the text issued by the seller to the buyer in economic activities, including the name, quality and agreed price of the products or services provided to the buyer. In addition to the advance payment, the invoice must also include the money paid by the buyer to the seller according to the agreed conditions, and must include the date and quantity, which is an important proof of accounting. According to China's accounting system, valid invoices for purchasing products or services are called tax invoices. The charging vouchers of government departments have different names in different periods and different charging items, but most of them are collectively referred to as administrative fee receipts. For internal audit and verification, each invoice must have a unique journal number to prevent duplicate or skip invoices.
