Hmm, I don't believe so @cody1357. 

To clarify, you've already set up a Wix store, and use Square as the payment processor for that, correct?  

From what I found in their community, it doesn't look like your Wix orders can be imported to ShipStation. Additionally, you would need to be using Square's online store in order to integrate ShipStation on our side, so I don't think there is a way to use the three together, unfortunately. Hope that helps clarify, let us know if you have any other questions.
