Starting in v2.0, SALES ANALYTICS uses the ATEND Framework to build sales reports. The ATEND Framewok must be installed before SALES ANALYTICS is. Both extensions are installed using the Joomla! Extensions Installer.
Go to Extensions → Install/Uninstall
Select the ATEND framework component file com_atend.zip included in the release, and press the Upload File & Install button.
Then select the SALES ANALYTICS component file com_salesanalytics.zip included in the release, and press the Upload File & Install button.
Go to Components → Sales Analytics to start getting your sales reports or press the Go to SALES ANALYTICS button.
