A purchase order refers to a special unit of a credit card issuer such as a hotel, restaurant, airport, shopping mall, etc., which records the cardholder's name, account number and consumption amount when accepting customers' credit card consumption, so as to collect money from the bank. That's what the purchase order is about. Importance of signing purchase orders

1. For merchants, signing purchase orders is mainly used for post-transaction such as reconciliation, liquidation and detailed inquiry, especially for disputed transactions. The issuing bank or cardholder can adjust the order, and the merchant needs to provide the documents that must be signed by the cardholder;

2. For the cardholder, the purchase slip is the historical evidence of the transaction. If you want a refund in the future, you should also provide this document as a transaction voucher;

3. Avoid criminal activities: the documents contain transaction data, bank card information, merchant number and other information. In order to prevent illegal use by criminals, merchants and cardholders should keep the documents (merchants should keep them for at least one year) or properly handle them.
