AbleCommerce is a great eCommerce Platform, but it natively doesn’t allow for feeding to Google Shopping. You can of course manually create a feed of your products in a spreadsheet, but this won’t be a great dynamic solution as you add or update new products in AbleCommerce.
With Feedonomics, you can dynamically send an optimized product feed from AbleCommerce to Google Shopping.
You can also do very interesting scheduling where you can update your feed hourly to deal with Google Shopping disapprovals.
