After looking at every multi-warehouse, inventory and shipping extension, I can find, I have settled on one closest to my needs. The cost is reasonable to my customer.
I looked at taking the time to develop the needed functionality and it is beyond my current abilities.
I am not sure many in the Magento Community need multi-warehouse functionality, my other customers don't need to manage several locations.
The developers have dropped customizing and conflict resolution and are focusing on developing the extensions, just this month Oct 18. It is guaranteed to work on standard Magento install, so that's where I'd have to start.
So My Question:
Is it OK to ask about this extension, about the experiences developers have had or about getting help customizing?
Also helpful would be extensions that are know to work with this one.
If it helps the discussion I will give the name of the Company and extension.
