Can two online stores share one inventory system?

[eyelashaddict]

I have two stores and I am wondering if there is a way to have them pull from the same inventory?

Example: Customer A order from website 1 two bottles of water.

Customer B orders from website 2 two bottles of water. 

Actual inventory in the store is 3 bottles of water.

So currently I am splitting the inventory between both stores, but it is making it difficult to know the correct amount of inventory if I am not at the warehouse to count it.  Is there a way to have one inventory and each store pulls from that inventory simultaneous without having to constantly adjust each website inventory. 

Or any suggestions on the best way to achieve this?

There are apps that enable you to automate the inventor synchronization process across multiple stores.
