Keeping some extra sets of certain products around can be beneficial if a technician loses or breaks part of a set and doesn't want to buy a whole new set to replace that part.
“I wanted to set myself apart from my competition. When items went on sale... I bought four sets of each. Not for the intention of resale but to have to warranty or in case someone lost one. I didn’t want to have to rob from sets anymore, so I bought parts boxes and put all of the individual pieces from those sets into their designated box, labeled them part number-wise, and adjusted my inventory accordingly.”
Powell explains this has benefitted him tremendously, especially with the pandemic making it more difficult to get select items in stock.
