"I don't have any idea how difficult it is to connect this software to an inventory system (it sounds complicated) but it seems like this software would work really well as an app for a phone. It would be handy for people who go to homebrew shops and don't have a recipe or the shop is out of what they need for their recipe. Then they could pull out the app and try to come up with a recipe on the fly. The shops could also use the software purely on their side to match customer preferences to their own kits or recipes."
I don't really know either, but my impression is that it would be daunting task. I have been in the process up building an electric HERMS system, and have the luxury of living a couple blocks from the St. Paul Northern Brewer retail store. Overall it's a great spot, but their handle on inventory management absolutely blows. I was trying to buy some 1/2 NPT male stainless quick disconnects, and dropped by the store. They had zero in stock, although their computer said they had 6. The employee checked their computer to see the inventory of their Minneapolis location, and told me they had like 16. I went over to Minneapolis and they had 6 of them.
In my opinion, Northern Brewer is as sophisticated as any homebrew supplier, but even they are a long way from being able to report/manage inventory levels appropriately.
