High inventory turnover rate

When the inventory turnover rate is high, it is due to the flow of the inputs and outputs of the products that are in the warehouse. This will be a good indicator to know how efficient the performance of the company is and how significant is the increase in its sales.

Low inventory turnover rate

It is a bit difficult to maintain high inventory turnover for all products in an inventory. For this reason, in a company, there will always be a wide variety of products, and some will have a low inventory turnover rate. They are equally crucial for the profitability of the company, and therefore they will always be indispensable.

Example: Supermarkets, because they sell different products, and among them will always be those with a low or high inventory turnover rate.

How does the inventory turnover ratio influence companies?

The turnover rate is very important for companies to know how many times the inventory must be replenished. As the inventory index is higher, the benefit of the company will be greater. The reason is that the index is high assumes that the inputs and outputs of existing products are constant.

When this indicator shows high figures, it means that the company had a large number of sales of its merchandise. To adjust the storage costs in the company, this indicator will also be very useful. The turnover rate will be the one that will let the company know how the efficiency of its sales is going.

Having lower-than-expected sales, the company will consider implementing some logistics strategies so that the turnover rate remains as high as possible. Seeing that a warehouse is emptying quickly, this means that the turnover rate will increase because sales have been a success.

Each company, regardless of the sector it is dedicated to, must use the turnover index to observe how its inventory is doing. If a company does not use this turnover rate, they will not know how their sales are going. In this way, the competition at any time can exceed them.

This indicator will indicate how often the warehouse must be supplied. From this result, the conclusion of the state and effectiveness of the company will be drawn.

Inventory turnover index makes the difference

Without the inventory turnover rate, a company cannot live because it would have no idea of ​​the management of its sales. This indicator will also help the company to know the amount of capital to invest. The higher the inventory turnover rate, the fewer capital owners must invest in storage costs.

For a company not to have losses, there must be a constant input and output of the products that are in the warehouse. In this way, the losses that can sometimes be a consequence of the products that expire in the store for long periods of storage will be avoided.

Regarding the investment in storage costs, they may vary according to the company:

  • A product that has a large number of sales needs more attention, and the cost of storage can increase.
  • When a product is the most sold, it requires more interest, and the company must have sufficient quantity so that there is always availability.
  • Each company, according to its needs, must implement different logistics to plan the storage of the products with the highest sales.

Due to all these characteristics, people should use the inventory turnover index by companies to learn more about the products they have for sale, and what strategies they should implement in each one, depending on their demand.
