WooCommerce is a rapidly growing platform and we're very happy to be part of helping site owners automate their stores. WooCommerce users can now enjoy the same automated order processing and inventory automation that our other users do. Also, as with all our users, we’re now processing inventory and orders for our WooCommerce sites in near real time.
For WooCommerce (same with Magento) we do not require any plugins or third party code to be installed on your system to work with Spark Shipping. We connect to the WooCommerce core API which makes installations and upgrades a breeze.
By now supporting WooCommerce we hope to help even more eCommerce sites increase their business though automation.
