You should also be receiving an email from PayPal informing you of an "Unclaimed" payment, along with further instructions on how to claim the payment and receive the funds.
Here are a few of the reasons why your payment may be "Unclaimed" in PayPal:
- Your PayPal account is in a different currency than the currency your clients used to purchase their order
- You have not yet verified your PayPal account
- You have made changes to your PayPal account email address
