@h20live We generally don’t test for compatibility with other third-party plugins.
You mention “multi-vendor” functionality, so I assume you’d like these vendors to be able to se the features added by WooCommerce Services, like printing shipping labels. If that’s the case, I don’t think that would work out of the box, unless the developers of those plugins have specifically worked in an integration with WooCommerce Services. You can reach out to their developers to ask whether compatibility for this plugin has been added.
WooCommerce Services being free, you can also install the plugin on your site and test it out yourself.
I’m closing this thread now, as it relates to third-party plugins we can’t provide further assistance with.
