Hello, dear, I am glad to answer your question. The method of inquiring about the invoices issued by other companies for our company is as follows: 1. Inquiring about the invoices issued by other companies to our company requires checking the invoices issued by the new VAT invoice management system in State Taxation Administration of The People's Republic of China. It is recommended that you directly contact the local competent tax authorities for handling. 2. The invoice issued by the seller to the enterprise can be queried on the VAT query platform. However, it is only limited to special VAT invoices, and ordinary VAT invoices cannot be queried at present. Ordinary invoices can only be queried by the number on the invoice.
