If your PayPal transaction is showing as Pending, there is a good chance that it was created as an eCheck. This is a payment type offered by PayPal and it behaves much like a physical check in that the funds need to clear before the transaction can be completed. This usually takes between 4-7 business days to complete. Once it clears, your transaction will be processed on our end.
If you do not wish to wait and would like your transaction cancelled, you will need to contact the bank you are using as the payment source for your eCheck. We are unable to cancel a pending eCheck transaction from our end.
