EditAdd-On (Defined)
The products Essentials and Premier include a lot of features right out of the box; however, additional features can optionally be purchased as part of what we refer to as an "add-on" that integrates and significantly enhances the base product.
Add-ons are purchased separately from the base product and, for the most part, can be turned on or off at any time depending on the purchase agreement and restrictions for each individual add-on.
