Hi
We've just released (in Beta) a simple app to automate bulk nightly CSV to FTP orders to third party warehouses. Since SHopify only has limited native integration with a handful of fulfilment houses we thought a simple tool like this might give merchants a bit more freedom with their pick pack and ship choices.
The app is brand new so we're looking for a handful of initial Beta testers to iron out any kinks before we release to the general public.
You can check it out here

Or feel free to send me a message if this is something of interest.
thanks!
