What are the best payment methods when selling web services? I was thinking of bank transfer and PayPal, but I'm worried about the charge-backs with PayPal. I've gotten very mixed results reading about how to prevent them, but surely I can lower the chances of the client attempting to do it? Or what are some precautions I should take to win a case? I've read about: Mailing a letter to sign and return (hassle..) Asking for a photo of their credit card or driver's license (I don't want to be asking for this info) Asking for a forward of the PayPal receipt Asking for a copy/scan of the signature used on the credit card Asking for payment through PayPal balance Any suggestions or tips?
