STAY AWAY!! I sold a boat, the charge was approved, delivered the boat, then the next day Appstar wanted documentation, sales slips, contracts, warranty, my dealer license you name it they wanted it. After a lot of back and forth they denied payment saying I wasn't approved to sell boats. I AM A PAWN SHOP AND USED VEHICLE DEALERSHIP I CAN'T TELL WHAT I MAY HAVE TO SELL, I AM BONDED LICENSED. Then they said I only had a 300 charge limit really?? Why would I keep a processor that approves charges and when it fits them or when YSTACovid-19 hit and sales are slim they pick and choose what they will or will not honor. User's recommendation: STAY AWAY.
