Ok, so Ive had a paypal account for a long time which I used for buying stuff online. Now I have a business started and have opened a business checking account. Do I need to setup a seperate paypal account? What if I want to buy something for personal use that is not part of my business - how do I keep that purchase from using funds from my business checking account, yet allow someone to pay me and then transfer those funds to my business checking account?
