consumers don't have to bear the tax point of invoices when they buy things. Merchants ask for money when they invoice, mainly because they want consumers to give up invoicing. This behavior is likely to involve tax evasion, and the tax price should be borne by the merchants, not the consumers. Therefore, as long as consumers ask for invoices, businesses must give them, and it is not allowed for consumers to bear taxes and fees.
