You cannot add more than 14,500 items to this list
QB Enterprise data files cannot be opened in QB Pro or Premier. Also, Enterprise data files cannot be opened in QB for Mac. The main reason to use QB Enterprise rather than Pro, Premier, or Mac is the list limits. All versions of Quickbooks other than Enterprise only allow 14,500 names in lists (Customer, Vendor, Items and Employees). If your list size is under these limits, you can safely convert your QB Enterprise data file to Pro, Premier, or Mac.
