Connects to Square so you can add books by ISBN, plan restocks, import invoices and build purchase orders. Muse can look up titles, update your Square catalog and help organize bookstore inventory and ordering.

Example request: "Add these five new releases to my Square catalog by ISBN and draft a restock order for the ones running low."
