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 3-5 business days to complete at which time your purchase will be successful in Arc. If you do not wish to wait and would like your transaction cancelled, please contact Customer Support.
