I’m starting a business as a sole proprietor providing coaching services to other businesses and individuals. I am the only employee. I understand businesses purchasing a longer, more expensive workshop may want Wire info, but for individuals purchasing an hourly session or a package of sessions, what is the best (and cheapest) way to accept payment?

I already use PayPal, Venmo, and Zelle for personal transactions, but I know to set up as a business charges a fee. Is there any reason I need to set these up as a business account, or can I just add my business email to my personal accounts and use them like normal? Is there another service I should look into?
