I want to have inventory from other businesses in my home garage,
I want to make a section of my garage, look like a mini warehouse. It will house different same parts that I will take and install onsite for different business. In other words, I want to warehouse vendor parts and install them for their warranty customers.

Has anybody ever heard of this and can provide some type of advice.
Also if there are any good websites I can look at to get a good idea on how I can do this from home.

I hope I can get big enough to move to a warehouse building.
Thanks
