What’s a SKU, You Ask?

An SKU is a secret code assigned to each product in a retail store or e-commerce platform. It’s the magic ticket that helps businesses quickly and easily pinpoint specific products. SKUs come in all shapes and sizes but usually involve a mix of letters and numbers.

Imagine you’re a clothing retailer with a fantastic t-shirt collection. You’d assign an SKU to each t-shirt design, taking into account size and colour. So, a large red t-shirt might get an SKU like ‘T-SHIRT-LR-RD,’ while a medium blue t-shirt could rock a ‘T-SHIRT-MB-BL.’

Why SKUs are the Real MVPs

SKUs are a big deal when it comes to inventory management. They give businesses the power to keep tabs on their products, stay on top of sales and demand, and ensure replenishment runs smoothly. Here’s a look at some of the perks of using SKUs:

Thanks to SKUs, businesses can easily track how many products they have in stock and where they’re located. This intel is essential for making smart decisions about restocking and avoiding the dreaded overstock or stock shortage. In fact, the Retail Owners Institute found that a well-executed SKU system can help cut inventory costs by 20-30% through better management decisions.

Sales and Demand Tracking

Unique SKUs allow businesses to track sales and demand, offering priceless insights into customer behaviour and buying habits. With this info, businesses can make informed choices about product pricing, promotions, and marketing efforts. A 2018 McKinsey & Company report revealed that retailers who use SKU-level data to optimize pricing and promotions could boost their operating margins by up to 2%.

Order Fulfilment

SKUs are also the heroes of order fulfilment, helping businesses quickly and accurately identify products and process orders. This ensures customers get their hands on the products they order quickly and efficiently. The IHL Group found that retailers with top-notch SKU management systems saw a whopping 50% reduction in out-of-stock occurrences, leading to happier customers.
