Stock Variance (Reports > Stock > Stock Variance)

The stock variance report works by comparing the actual stock usage between two dates -as recorded by the user- against theoretical stock usage as calculated from recipes of items sold in that time.


 Next is Variance. This column shows the difference between the Actual and Theoretical figures. This is the most important column in the report! Ideally, the variance should be as low a figure as possible. Any stock that is in variance is considered unaccounted for.


 Addressing your variance is important to keeping your stock under control. Generally, there will be several reasons for stock to be in variance:


  • Errors in recording Stock Movement
    If the user has made a mistake when recording in Backoffice, these mistakes will reflect in one or more of the first four columns, and as a result, show an incorrect Actual Stock usage figure.

  • Incorrect Recipe
    If a menu item’s recipe is incorrect, it will not deduct the correct amount of stock when a sale is made. Please contact the Helpdesk if you suspect there is a menu problem.

  • A physical problem with Stock Control
    The primary purpose of the variance report is to identify and correct any misuse of stock in the store. As a result it’s often the case that a variance is caused by stock actually going missing, due to errors or theft.
