Not sure if this has been shared before, but I've seen people ask about it recently so I thought it would be a good idea post it. If you're a digital service provider like me, chances are you've been screwed out of a payment before. After being screwed many times over the years, I've come up with a method that has prevented this from happening completely, it's nothing special and doesn't involve rocket science but IT WORKS. When you receive the payment, make sure you're eligible for seller protection (the buyer has provided you with billing and shipping details). You can confirm this by viewing the payment details. If it says ineligible, refund the payment and tell the buyer to send another payment, but with a verified shipping address. If they make a big deal about this, chances are they have intentions to scam you. Next you will print out an invoice, put it in an envelope and ship it to the buyers address. You will have a tracking number, and if the buyer tries to reverse the payment, or claims unauthorized payment, you can provide Paypal with the tracking number to prove that you've sent out the product that has been paid for. This will ensure you will not lose out on the money. An alternate to this method is to create an invoice from the Paypal interface. Again, sorry if this has been already posted. Good luck guys, take care and make sure to always cover your ass!
