Didi has a group that receives invoices.

invoices refer to business vouchers issued and collected by all units and individuals in the purchase and sale of goods, provision or acceptance of services and other business activities, which are 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, not whether the money has been received or not.

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 include the payment from the buyer to the seller according to the agreed conditions, and must include the date and quantity, which is an important proof of accounting.

China's accounting system stipulates that valid invoices for purchasing products or services are called tax invoices. The vouchers of government departments' fees and levies have different names in different periods and different fees and levies, but most of them are collectively referred to as administrative fees and receipts. For internal audit and verification, each invoice must have a unique journal number to prevent duplicate or skip invoice numbers.
