This plugin makes the necessary posts to Google Analytics to track your sales and all of the items in the user's cart at the time of the sale. You must have Google analytics enabled in your OpenCart admin and Google Ecommerce must be enabled in your Google Analytics account.

Important: The Ecommerce plug-in should not be used alongside the Enhanced Ecommerce (ec.js) plug-in.

For more information on what this extension accomplishes, please see the documentation here: https://developers.google.com/analytics/devguides/collection/analyticsjs/ecommerce

Just upload this XML file to your vqmod/xml folder and start tracking your sales.

To test, just add something to your cart and go to your-domain.com/index.php?route=checkout/success and check that the source code matches the documentation from google.
