I work in a research lab. Among other things RTM is an essential tool for ordering and inventory for the lab. With my RTM account, I keep track of expiration dates and how much we have of something. Each item is an individual task. In the notes section I put the expiration date, quantity we have and the catalog number for easy reordering. For items that we use frequently I set as repeating tasks so we never run out. RTM has made a somewhat daunting task easy.
