Generally, faster turnover is good, since the business can generate high sales while investing in relatively modest amounts of inventory. Conversely, slower turnover likely means that there is some obsolete inventory in stock that may need to be written off. In addition, slower turnover implies that the business is investing more working capital for each sales dollar earned. For example, the firm may choose a period of 3 months, after which it may qualify any unsold inventory as aging.

Staying on top of the age of products sitting in inventory is important. Inventory is one of the largest―if not the largest―assets you’ll have on your books. Therefore, it’s important to keep tabs on how much inventory is sitting on the shelf and for how long. This will give you insight into what products customers are buying so that you don’t invest a lot of money into products that will never sell. While the inventory aging report isn’t common in accounting software for small businesses, it’s often found in accounting software that’s ideal for mid- to large-sized companies. For example, Odoo and IBM allow you to generate an inventory aging report.

Retailers may now precisely identify which products are raising higher carrying costs or holding fees as they go unsold owing to aging inventory calculations. From there, business owners may eliminate outdated inventory to ensure an uninterrupted revenue flow. In theory, the ideal inventory age can be a week, a month, or even up to 90 days from the supplier’s delivery date. Conversely, most companies consider items that sit for more than six months or 180 days to be dead stocks.

If these goods cannot be sold off soon, they may be written off entirely and junked. Inventory management can lead to issues around depreciation, obsolescence, and shelf life. On the one hand, if an ecommerce business specializes in technology of some sort – consider the impact if a new model is introduced that happens to render previous versions obsolete. Similarly, if the ecommerce store specializes in CPGs (consumer packaged goods), attention should be paid to the possibility that products can expire before they’re sold. In both of these cases, the company might have to realize a loss due to the issues tied to aged inventory.

  1. But walking up and down the aisles of your warehouse won’t help you figure out what these products are.
  2. There are 50 units in stock from the October 1 receiving and those have aged only 15 days.
  3. And you can use these insights to build more accurate inventory plans based on what customers actually want (or don’t want).

It’s not just a waste because it signals ineffective inventory management, but it also will likely decrease your revenue since there is less demand for these goods. This assists retailers in buying the right amount of inventory and deciding how frequently to place reorders. Inventory age can significantly influence inventory planning because it recognizes which products don’t need to be reordered. Your management has a clear roadmap to work from and eliminates much of the guesswork involved in this process. Products that have reached the end of their product life cycle but have yet to be sold constitute excess inventory. A product surplus not only indicates inefficient inventory control but will also negatively influence your income.

One way to incentivize purchases is to generously discount the item or include it in a limited-time bundle with some of your bestsellers. Many brands do this by running end-of-season sales to clear excess inventory before it becomes dead stock. Aged inventory refers to slow-moving products that either aren’t selling or have outlasted projected demand. This can result from several factors, like seasonal purchasing behavior, insufficient marketing, poor positioning, or excess inventory. Aging inventory has a direct impact on your business, as it can help you understand your stock on a deeper level. Aging inventory reports highlight key metrics about the health (and status) of your oldest inventory items, and may dictate whether a certain product is a good ROI.
