I have 2 questions about using paypal with coaching clients.

1) I would like to offer them the opportunity to pay by credit card via my paypal account. I know that a client click on a button on my website and pay that way. I have heard about sending a paypal invoice on the date of service. Have any of you done that? Which is better?

2) Do you have coaching clients that you work with over the phone pay on paypal before the session or trust that they will pay for the session afterwards?

Thanks for any advice you can provide!
