PAR Levels & Reorder Quantities can be considered a floor and a ceiling, respectively, for your ideal inventory levels. Keep reading for more of a breakdown along with a graphic to help explain precisely what we mean:

This is the ideal minimum quantity you want in stock at all times. This is similar to an Alert level and is extremely valuable for keeping a well-stocked shelf and avoiding running out of a product.

PAR Levels can be thought of as a soft floor.

It's good to think of your Reorder Quantity as your ceiling. This is how many units make for a "full" product shelf.

Another way to think about the Reorder Level is the quantity you want to return to when it hits the PAR Level. In theory, this is your ideal maximum for the given product.

Easily manage your inventory with the "Auto-Add PAR Products" feature. With a single click, you can automatically add products below their PAR levels to your Internal Transfers or Purchase Orders.

If you've set Reorder Quantities, we'll automatically fill in the units needed to bring your stock back to the desired level, ensuring you don’t overstock.

Let's say I want to keep a minimum (PAR) of 10 units on my shelf at all times. Once I get to 10 or below, I want to get back to a (Reorder) quantity of 20. 

When I get down to a quantity of 5 units (below my PAR of 10), my next Purchase Order would automatically order 15, to get me back to my Reorder quantity of 20.

To set or edit these default values, click on the product name on the Products & Variants page:
