Inventory Management Solution Software with Excel - repost

I am not sure what I am looking for but I am hoping the freelancer community might be able to help me with my situation. A little about my situation, I am an Amazon seller. I have inventory in two locations, one at my home based office, and two at Amazon Fulfillment locations. I want an application that I can simply open up and it would give me a constant live update of my inventory level which will include quantity and item cost from both locations. Please private message me with your ideas and your estimated bids for the project, NOTE: I am aware that alot of you may be using bots to post bids into my project, to actually filter out the freelancers who actually take their time to read my post and write out a well thought out solution to my private message please include in your private message me with the security phrase "I AM READY TO WORK" Only PMs with this security phrase will be taken seriously and have a better chance of being awarded the proejct
