I am thinking of using Paypal with my online Life-coaching business, but I don't see where I can go on the site that it'll show me what options are available regarding very basic things, like how to set up direct billing with a client, how I can pay for that to be done for me, etc. Where can look?
first you must review the terms and agreement you signed,pay attention to buyer and seller protection and what items are eligible for protection,what is a dispute and what kind of dispute and what is a credit card chargeback and fee schedules.
you have no seller protection for the service you provide,browse this site and learn what the problems seller face.
there are many ways to accept paypal,send money request,apply for a card reader called PAYPAL here,send invoice .
