As a Symbiostock user, you can add any plugin you’d like to enhance your store. Other than WooCommerce, Symbiostock and WordPress, there are a number of functions you could want to include in your store to increase its functionality.
Some of these types of plugins may include SEO, statistics, payment modules, tax modules, and security modules, to name a few. We recommend not installing too many, however, as enabling many plugins that are not necessary can sometimes slow down your website substantially. Also ensure that you acquire plugins from reputable sources as plugins go through no specific quality control to be distributed, and may have bugs and/or exploits that could compromise your entire server.
You can discuss and ask about various third party plugins on the Symbiostock forums.
