Firstly - almost no other apps or services do what Order Desk does. It can stitch together anything to anything (different selling channels <> different fulfillment providers, on-demand printers, etc.). You can craft unique rules for each instance and the platform keeps great logs. There is a bit of a learning curve, but once you 'get it', you get it and it is like a box of legos... you can build whatever you can imagine. My favorite part of Order Desk is the support. They were AMAZING when we tried to setup our brand's super odd and different requirements. They helped us debug and test and made recommendations. When one of our main on-demand partners had a MAJOR technical glitch (but wouldn't admit it), Order Desk devs were there to troubleshoot - and talked directly to the on-demand printer to fix the API. Fantastic communication, transparency and an all around great attitude. High fives to Louie, Katie and Pieter over there at Order Desk. You guys rock!

The support team is brilliant and very helpful at answering our questions and making sure the app works for our use case. That said, this looks to be the best wholesale app out there for bulk pricing, user control, custom shipping options and all the other things you'd need (but don't think about) for a wholesale store built ON TOP of a consumer store.
