Shopify is not a product information management (PIM) system on its own and is only ideally used for a small storefront (on its own), so yes it can integrate with a variety of popular PIM systems to manage the product catalog(s) and systems used to support sales such as ERP systems, CMS, warehousing, POS, procurement, data suppliers, print, digital channels or more. Popular PIM systems include Jasper, Akeneo, PlyTix and Sales Layer, among others.
