Mednefits' Company HR Portal offers the feature of exporting the expired entitlement of your employees! You can export the balance from last year after each entitlement reset exercise. 

Navigate to Benefits page > Employee Tiers and Schemes > click on Export All Expired Entitlement which is located at the bottom of Employee Tiers.

The Export All Expired Entitlement will be downloaded as an excel file and you will be able to view all the data for all employees despite having different employee tiers.
