Shared Inventory

[NPE]

Ability to share inventory across multiple locations.  As a business who has a single inventory and sells online as well as travels to multiple expo events to sell in person, I need to be able to know where the item was sold for sales tax purposes, but not keep separate inventory for all locations.  If an item is sold online or 'on location', the shared inventory count should be updated.

At minimum, when creating a location, the option to "Use shared Inventory" or "Shares Inventory" should exist so that when selling an item at a mobile location, the primary inventory counts are updated.  If an item is sold online, that same primary inventory count is updated. In other words, I do not have to keep separate inventory between online and each mobile location I may travel to.  Mobile locations such as craft shows, expos, etc. are generally for a day or weekend and not permanent.  If a business had online sales, multiple store fronts, and mobile locations (expos, craft fairs, other 1 time events), I would expect that my primary location's inventory would be shared with my online site and all of my mobile locations where I've elected to share inventory with my primary location, but additional store front physical locations may have a separate inventory (meaning when I created those locations I would NOT set the "Shares Inventory" option)

To expand on that, adding more granular tracking, you could "transfer" some of the items in the "Main inventory" to another location.  This would let you easily know if items were stolen at that location.  Once the event has concluded, transfer remaining stock back to the "Main Location".  This additional functionality would accommodate businesses who may vend at multiple event simultaneously, adding tracking information by location and by team assigned to that location for the day.

I would have never created additional locations had I know it was going to really make a mess of my inventory.  I only did because I was trying to find a way to automatically apply the appropriate sales tax based on where I was physically selling that day.

This is exactly the feature I need! I sell it multiple farmers markets, and created locations so I can track sales out of each, but definitely want to still have one single, shared inventory that they all sell from.

Absolute must. I have a single warehouse location that supplies my brick & mortar shop as well as the website. In addition, I have recently acquired a specialty business that compliments the shop but sells online only using common stock, to have shared or pooled stock that is sold in multiple locations would be great. It would remove the issue of managing stock lines allocated to each location and potentially missing sales.
I don't believe this would be too hard an option to activate, as the price of an item is shared across multiple locations, please do the same for inventory.
