How to integrate distributor into store to print shipping labels.

[MHT1]

Hello all,

I've setup my store, everything is cash money, except trying to integrate my distributor into it. They ship with shipstation, and I plan on using Shopify only for my shipping labels. How do I integrate them into the store so they receive my order information? 

Do I just make them a user of the account? Or is there a more efficient route?
