Seems most of us don't do anything to the vaccines/supplies inventory control other than checking fridge temperatures..I'll try to do the inventory control in our clinic myself and give you an update and how to list. One of our friends give a company credit card to his trusty employee who handle all the orders for him. He always keeps more than 10K in card's available credit. My wife is much more prudent than myself, like looking for a cheaper vaccines suppliers, but not knowing much what is going on in the back room.
