If you are a new freelancer looking to receive payments through your PayPal account, I suggest you should register for personal account if your country supports PayPal.
In case you decide to grow and be a full-time freelancer and earn more than 10K $ per month then you can easily upgrade to a business account later.

But the country you are living in if it doesn\’t support PayPal and you want to accept credit card transactions online or in person, you need to open a PayPal business account. Your customers do not have to have a PayPal account, they can check out as a guest.
