To measure your record keeping performance, you need to use some key performance indicators (KPIs) to evaluate and improve your record keeping processes and outcomes. These KPIs include the inventory accuracy rate, which is the percentage of your records that match your physical inventory count, and the inventory shrinkage rate, which is the percentage of your inventory loss due to theft, damage, misplacement, or poor record keeping. Additionally, you should consider the inventory turnover ratio, which is the number of times your inventory is sold or used in a given period. Furthermore, you should take into account the inventory carrying cost, which is the total cost of holding and maintaining your inventory, including storage, insurance, taxes, and depreciation. Lastly, you should monitor the inventory days – the average number of days your inventory stays in your warehouse or store.
