Invoice refers to the text issued by the seller to the buyer in economic activities, including the name, quality and agreed price of the products or services provided to the buyer. In addition to the advance payment, the invoice must also include the money paid by the buyer to the seller according to the agreed conditions, and must include the date and quantity, which is an important proof of accounting. According to China's accounting system, valid invoices for purchasing products or services are called tax invoices. The charging vouchers of government departments have different names in different periods and different charging items, but most of them are collectively referred to as administrative fee receipts. For internal audit and verification, each invoice must have a unique journal number to prevent duplicate or skip invoices.

Provisions: In any of the following cases, it shall not be used as the VAT input tax deduction certificate after certification, and the tax authorities shall return the original, and the buyer may ask the seller to issue a special invoice again: 1 Unable to authenticate The term "unable to authenticate" as mentioned in these Provisions means that the ciphertext or plaintext listed in the special invoice cannot be recognized and the authentication result cannot be issued. 2. Inconsistent taxpayer identification number authentication "Inconsistent taxpayer identification number authentication" means that the buyer's taxpayer identification number listed in the special invoice is wrong. First, check whether the invoice code is consistent with the code scanned into the computer. If not, it may be a recognition error after scanning. It is recommended to manually modify it to the correct code again. If the error of invoice code is still displayed, it may be that the drawer has not uploaded the invoice information, and the general system data synchronization cycle needs at least 1 day, so the invoice issued on the same day cannot be retrieved on the national VAT ordinary invoice query platform.
