We recently introduced this, we have 6 shipping stations in our main site and introduced Scan Verify and Print for as much as possible (we can't for some shipments due to their destination requiring us to specific products in certain packages and shipstation doesn't do this will with Verify and Print - it is done manually by us with split shipments).
Anyway we have set it up like this:
It's maybe not the best, new to use but has formalised things a lot. It's definately reduced the number of errors in picking but it was a lot slower initially, it took perhaps a month for things to speed up and staff to get used to it.
I've no idea what normal Shipstation clients are like - hope it helps.
