The top three ERP packages for use with Magento e-commerce are SAP, Microsoft Dynamics AX, and NetSuite. These powerfully ranked ERP solutions go beyond the custom account operations, allowing for flexible configuration, numerous services and increased customization to add efficiency to your business.
