I own an artisan market where vendors rent shelves and display their own goods. I love using square for our point of sale and online store, but managing all their listings and entering new products is becoming too time consuming. Is there a way that a vendor can create their own listings, and enter items into the online store themselves, but not have access to other people's items and to my whole Square account? I know other platforms can, but I am really hoping not to leave Square.  Thanks!
