Artist Advice: Paypal

[sperkl.livejournal.com]

So I'm new to the world of sellng art, as in just this week did I decide to sell adopts. I made a Paypal account, set it up from what I thought, read up about creating invoices, everything was going smooth until I made my first sell. At first it wouldn't let me accept money, so I upgraded to a business account. Things when fine after that, but I want to make sure I'm doing things right.

My first question is, should I have upgraded to a business account? I plan to sell more adopts in the future mind you.

Also What is the right way to set up an Invoice? One that doesn't expect me to ship something.

Sorry if I posted this wrong, I'm also new to this community.
