I would like to start accepting payment via Paypal, but since I don't have a corporation, I'm worried it would look unprofessional if my name appears at the paypal checkout instead of a company name. Does anyone know whether you can change that to your website name or something else if you don't have a corporation?
This is correct, you don't need a corporation, just a PayPal Business account. You may need a "business bank account" to open a PayPal business account, though. But who knows how carefully they check whether it's a "business bank account" or how well-defined the term "business bank account" is in different countries anyway?
