Dear, if you buy things in a small shop (the business area is as small as tens of square meters, the sales staff 1-5, and the turnover is not high), no matter how much you buy, the small shop will not invoice you, because they have a fixed tax, that is, no matter whether the business is good or bad, they will pay a fixed amount of tax every month. If every customer who comes to buy something is invoiced, the store will have to pay extra foreign tax, which the general store can't afford.

If you buy things in large and medium-sized shopping malls, restaurants, regular specialty stores, jewelry stores and other places with large business area, many people and high turnover, you have the right to ask the merchants for invoices no matter how much you spend. Because they pay taxes according to their turnover, the amount invoiced reflects their turnover to some extent.

Invoices are used to reimburse ordinary people. Of course, some units require employees to pay with invoices of the same denomination, which is illegal to some extent.

For businesses, it is the basis of turnover. The more you provide, the more tax you pay, and of course the more value you deduct.

Generally, it's useless not to reimburse you when you come. Of course, if you want an invoice, you can supervise the merchants to pay taxes.
