Venmo is a convenient way to pay friends back and send money between friends. The new purchases option is frustrating. I don't operate a business, but one of my wife's friends clicked yes on the purchase button when he was paying her back for some girl scout cookies. Now Venmo is asking me if I want to set up a business account and there is no way for me to reject the transaction or specify that I don't want to receive purchase payments. Now I have to remind friends not to click that button.
