What is the Difference Between the Two
To begin with, keep in mind that Magento Enterprise Plus gives you access to all of the same options and controls that you would get with the standard Magento Enterprise. The difference between the two products would have to do with the extras that are included with Magento Enterprise Plus. Below is a list of differences. In other words, the list below includes the things that you will not get with basic Magento Enterprise.
• Multiple licenses with a single purchase.
• Access to Magento Consulting.
• Free access to Magento eCommerce Training.
• Access to enhanced, 24 hour support.
The main difference between the two products would be that Magento Enterprise Plus is designed to offer more control, more options, and better support. However, it is a software that will work best for very large businesses. Medium to large businesses would better benefit from the options available from Magento Enterprise.
