How much time my inventory stays in the warehouse?

How much money do I spend in procuring products/raw materials?

What is the average sale I make against my average purchases?

Which are the product I should stop investing in order to minimize the no of SKUs?

Ordering excess quantity will result in carrying cost of inventory, whereas ordering less will result in the increase of replenishment of stock. The supplier’s shipping cost also bring strong variations on the cost per unit of order.
  • Carrying Cost: How much are you spending on storing your inventory? Which include renting storage facilities, electricity, wages etc.

How to control these cost, calculate the correct Reorder point
