Once you set up your Anython page, you will automatically receive an account to receive payments from your family, friends and local community that you gather pledges from. For personal causes, you will set up a WePay account to be paid. Visitors to your page complete their pledge and pay by credit card in less than a minute.
If you are raising money for a non-profit organization, the money will go directly to them via check. You don't worry about a thing.
