PAR (PAR level)
Keeping your inventory “at par level” means having a set minimum of each item that you’ll have on hand at all times. You probably do this in your head anyway, over time getting a sense of how often you need to re-order certain products or inputs you use in your business. While it’s good to always have extra inventory on-hand, having too much can be tough to store and tie up your cashbox.
There are more math-y programmes that can help you figure out your (very official sounding) Periodic Automatic Replacement levels, and you should use these numbers in whatever inventory management system you use. Quick trick - set up Shopify Flow to automatically re-order things when your inventory gets to the par level you’ve set.
