Beauty salons can issue invoices when purchasing products. To issue an ordinary VAT ticket to an individual, you don't need a tax number, just fill in your name. The rest address, telephone number, bank, account number, tax number, etc. do not need to be filled in. Although the state requires that all ordinary invoices issued must have tax numbers as reimbursement vouchers, they cannot be recorded without tax numbers, except for ordinary invoices issued to individuals and government agencies. Therefore, it is ok to invoice individuals normally.
