 ## Comparison to the Download Portal
 
 The Enterprise Portal is the next generation version of the Replicated Download Portal. Compared to the Download Portal, the Enterprise Portal not only provides access to installation assets and instructions, but also allows users to track available updates, manage their team and service accounts, view the status of their instances, view license details, and more. These features are designed to make it easier for your customers to manage their instances of your application from a centralized location outside of the installation environment.

+### Customer Reporting
+
 The Enterprise Portal sends insights back to the Vendor Portal, which are surfaced on the **Customer Reporting** page. For more information, see [Enterprise Portal](/vendor/customer-reporting#enterprise-portal) in _Customer Reporting_.
 
 These insights include details about the customer's install attempts. The Enterprise Portal tracks and reports on install attempts by creating unique, _just-in-time_ service accounts. These service accounts allow the Enterprise Portal to send data back to the Vendor Portal when the user starts and completes the installation or takes other actions that are specific to the installation type. The service accounts also provide realtime feedback to the user on their installation progress using checkboxes and status indicators, and allow users to pause and return to an installation attempt. For more information, see [Install Attempts](/vendor/customer-reporting#install-attempts) in _Customer Reporting_.
