Managing SKUs for Efficient Inventory Control and Sales Reporting


In the world of retail, effective inventory management is crucial for maintaining smooth operations and maximizing sales. One of the key tools that businesses use for this purpose is the Stock Keeping Unit (SKU). In this article, we will explore what SKUs are, how they differ from barcodes and UPC codes, and why they are essential for inventory tracking and sales reporting. Additionally, we will delve into the best practices for formatting SKUs, providing practical examples to help you get started.

What are SKUs?

SKUs, or Stock Keeping Units, are unique codes used by businesses to internally track their inventory and report on sales. SKUs are different from barcodes and UPC codes, as they are specific to each business and can be created according to their own preferences. Many business owners opt to label their products with stickers displaying the SKUs for easier exchanges, returns, and customer inquiries.

Difference between SKUs and barcodes/UPC codes

While barcodes and UPC codes are globally unique and issued by standard organizations, SKUs are internally generated by businesses. This allows businesses to have more control over their inventory tracking and tailor their SKUs to their specific needs. Unlike barcodes, SKUs can include information about product attributes such as style, color, size, pattern, or storage area.

Importance of SKUs for inventory tracking and sales reporting

SKUs play a critical role in efficiently managing inventory and generating accurate sales reports. By assigning a unique SKU to each product, businesses can easily track its movement, monitor stock levels, and identify top-selling items. SKUs also enable businesses to generate detailed sales reports that provide valuable insights into product performance, customer preferences, and overall business profitability.

How to format SKUs

When it comes to formatting SKUs, there are a few guidelines that can help businesses create effective codes. Here are some key considerations:

  1. Characters allowed in SKUs: SKUs can consist of numbers, letters, or a combination of both. It is important to avoid formats where numbers like one and zero can be confused with letters like O and I. Special characters, symbols, and spaces should also be avoided, as they can cause issues when searching for specific SKUs. However, dashes and underscores can be useful for separating groups of numbers or letters, especially when representing different product attributes.

  2. Length of SKUs: SKUs should be kept as short as possible, typically no longer than 16 characters. Depending on the variety and number of products a business sells, shorter formats ranging from four to eight characters can also be effective.

  3. Keeping SKUs simple and understandable: Each letter and number in a SKU should have a purpose and contribute to the overall clarity and functionality of the code. Random combinations of characters should be avoided to ensure that SKUs are easy to understand for staff members involved in picking and packing orders.

  4. Ensuring uniqueness of SKUs: For effective tracking and sales reporting, each SKU number must be unique. Even if a business offers variations of a product (e.g., different colors or sizes), each variant should have its own unique SKU based on the specific attributes.

Examples of SKU formatting

To provide a better understanding of how SKUs can be formatted, let's explore a couple of examples:

Example 1: Boutique store Paige owns a boutique store where all her products have a brand, style, and size. She chooses to use a ten-digit numeric SKU format, separating the digits with hyphens. For instance, a SKU for a black t-shirt with a specific brand, style, and size may look like this: 4225-776-3234.

Example 2: Wooden pen business Jimmy runs a wooden pen business and finds it helpful to sort and store his products by type, ink color, and point size. He decides to use an alphanumeric SKU format, using underscores to separate the different attributes. For example, a SKU for a pen made from walnut with black ink and a 2.5 millimeter point size could be: wal_blk_25.


Effectively managing SKUs is crucial for businesses of all sizes in order to streamline inventory control and optimize sales reporting. By adhering to the recommended formatting guidelines and considering the uniqueness, simplicity, and understandability of SKUs, businesses can enhance their operational efficiency, improve customer experiences, and boost overall profitability.
