Enterprises can handle accounts by debiting prepayments or accounts payable, and then write off their own accounts after receiving invoices.

If the supplier cannot provide the invoice, the financial department should organize professionals to evaluate the goods involved, and the financial department can "estimate and record". After that, you need to continue to ask suppliers for commodity invoices. If the supplier really can't provide a valid invoice, it shall apply to the local tax department, provide written materials of the goods and explain the relevant situation, and ask for a new invoice.
