There are many different online stores out there, so here is an explanation of when it would make sense to use PeachPay.
Customers frequently make one-time payments (without you shipping them a physical item). For instance, suppose you sell a software license that only needs to be purchased once. You don't require a shipping address because there's nothing to ship.
Customers frequently make one-time payments (and you ship them a physical item). You might sell a fun gift that someone would probably buy once, but not many times, like a custom puzzle set. PeachPay supports collecting all the necessary shipping information for the US, Canada, and India.
Customers make repeat purchases. Like the once time purchase, the customer just scans the QR code of a single item or a cart of items, and you get their order.
