In the world of retail and e-commerce, inventory management is crucial for success. SKU numbers, or stock keeping units, play a critical role in this process by providing a unique identifier for each product. In this article, we’ll discuss what SKU numbers are, how to find them, and how to use them effectively.

What is a SKU number?

A SKU, or a stock keeping unit number is a unique identifier assigned to each product. It typically consists of a combination of letters and numbers and serves as a reference code for inventory purposes. The purpose of SKU numbers is to make it easier to track sales, inventory levels, and restocking.

Where to find SKU numbers?

There are several places where you can typically  find SKU numbers, depending on the product and where it’s sold. 

Retail store and e-commerce websites. If you are purchasing a product from a retail store or an e-commerce website, the SKU number is often displayed alongside the product description. Look for a number that is unique to that specific product.

Product packaging and labels. Most products have a barcode or printed number on the packaging or label that serves as the SKU number. Look for a series of numbers or a combination of letters and numbers that are unique to that specific product.

Invoices and receipts. If you’ve previously purchased a product, the SKU number can often be found on the invoice or receipt. Look for a line item that includes the product name and a unique identifier, such as a SKU number.

Accounting software. This method of finding SKU numbers will best work for business owners. In order to do that, you need to navigate to the inventory management module of the accounting software being used, which may be labeled as “Inventory,” “Products,” or “Items”, then  find the specific product by searching for the product name or browsing through the product list and check the SKU field labeled as “SKU” ,”Stock Keeping Unit” or “Product ID.” 

Your sales platform account.  It’s another way to look for information about SKU numbers for e-commerce businesses. To find a SKU number in your account on the sales platform you use for selling your goods, you’ll have to take the steps similar to finding it in the accounting software.

Why is it important to track SKU numbers?

It’s important to track SKU numbers because they’re an important component of effective inventory management for the reasons mentioned below. 

Without accurate SKU numbers, it can be difficult to determine which products are selling well and which ones aren’t. This can lead to overstocking of certain products, which ties up capital and takes up valuable space in the warehouse. It can also lead to stockouts, which can result in lost sales and dissatisfied customers.

In addition, accurate SKU numbers are important for streamlining the order fulfillment process. With the right SKU numbers, businesses can quickly locate products in the warehouse and fulfill orders in a timely and efficient manner.

Finally, SKU numbers are vital for accurate record-keeping and financial reporting. They provide a way to track the movement of products through the supply chain, making it easier to generate inventory reports, sales reports, and profitability reports.
