How do property companies invoice for electricity charges?

If the property company and the water and electricity supply unit sign an entrustment contract, the property company is only responsible for collecting and paying the water and electricity charges at a fair price, and then the supply unit issues an ordinary invoice to the property company. Legal basis: Article 19 of the Measures for the Administration of Invoices in People's Republic of China (PRC). Units and individuals that sell goods, provide services and engage in other business activities collect money from outside, and the payee shall issue an invoice to the payer; Under special circumstances, the payer will issue an invoice to the payee. Article 20 All units and individuals engaged in production and business activities shall ask the payee for invoices when they pay for goods, services and other business activities. When obtaining the invoice, you are not allowed to change the name and amount.
