I am starting my own Shopify store and want to link Paypal with it to accept payments. It wants me to login with a business account to link it. Currently, I have my own personal stealth account that is aged with no limits and I've been receiving/sending money through it regularly. I was wondering if I should just upgrade this account to a business account or create a new Paypal business account with another email? I'm concerned that if I start receiving more regular/larger payments on my stealth account, they will ask for identity proof or other documents. My concern with opening a new business account would be that they can limit me very quickly and hold my money for 21 days. Can someone advise me on which route to take?
