PDI acquired CStorePro and is now PDI CStore Essentials. At PDI CStore Essentials, we are creating an end-to-end solution that helps simplify your daily operations and keeps you focused on the things that matter most. We believe single-site/independent operators should have access to simple, easy-to-use, modern tools to help manage their pricebook, inventory, vendors, scan data, and improve customer loyalty – all from one place and at a low cost.
