Basically agree with the last answer. There are the following supplements:

1. Generally speaking, PayPal has the following payment methods:

A. balance payment (immediate receipt)

B. Credit card payment (received immediately)

C. Bank recharge payment (first from the bank to PayPal, and then through the balance payment, similar to A)

D.e-check payment (equivalent to issuing an electronic check from the bank and then paying through PayPal. It usually takes 7 days for the payer to receive the payment from the payee, and it is not recommended for the merchant to deliver the goods at this time)

2. The best way to prove payment is to ask the payer to show the transaction ID, that is, the transaction number. So you can find it even if you call PayPal customer service.
