What is SKU?

An SKU, or Stock Keeping Unit, is a unique alphanumeric identification provided to each product for sale that identifies it from other items in the inventory based on variables such as category, size, colour, brand, and other features.

For example, a red medium-sized t-shirt from Brand X may be labelled with the SKU X-TSHIRT-RED-M.


Retailers use SKUs to track products, manage stockroom search operations, organise products, and categorise items based on price, colour, and size. Whether you run an ecommerce website or a physical store, assigning SKU numbers to products improves order fulfilment efficiency, regardless of inventory quantity.

Best Practices to Follow in Creating SKU for Better SKU Mapping

Creating effective SKUs (Stock Keeping Units) is critical for efficient inventory management and seamless business operations. Here are some basic practices to consider while developing SKUs:

Keep It Simple, Unique and Consistent

In order to prevent confusion, employ a simple, consistent format for all SKUs, making sure the structure is logical, unique, and easy to understand for anyone who might need to use it. Additionally, keep SKUs to a reasonable length, usually no more than 10-15 characters, to make them manageable and easy to read.

Make it Informative

To categorize your products effectively, start with broad categories and narrow down to specific details, incorporating descriptors such as category, brand, size, color, and other unique characteristics. For instance, a red medium-sized t-shirt from Brand X could be labeled as "X-TSHIRT-RED-M." Utilizing a tool like the ZOHO Free SKU Generator can streamline this process by automatically generating SKUs.

Avoid Special Characters

Refrain from using special characters or spaces in your SKUs. Stick to alphanumeric letters, hyphens, and underscores. Special characters can occasionally cause problems in databases or during integration with other systems.

Plan for Scalability

Ensure that your SKU structure can support additional products without major modifications. Allow room for additional products and new categories. For example, if you intend to broaden your product line, avoid hard-coding product kinds.

Document Your System

Clearly outline your SKU creation procedure and guidelines. This provides consistency even when several people create SKUs. Provide training and reference resources for employees to use.

Regularly Review and Audit

Review your SKU system on a regular basis for irregularities or areas for improvement. Perform regular reviews to ensure that all SKUs are used correctly and consistently.


Ultimately, SKUs play a crucial role in ensuring efficient inventory management within the retail and e-commerce sectors. With the use of unique IDs for each product, businesses can optimise their operations, improve customer satisfaction, and make informed decisions based on data. SKUs offer a wide range of benefits that span across different sectors. They enable efficient inventory tracking, optimise supply chain management, and ensure accurate financial reporting.
