What is SKU swapping?

SKU Swapping refers to the practice of replacing one product (identified by its Stock Keeping Unit or SKU) with another SKU, often during subscription management, inventory adjustments, or personalized product replacements. It’s commonly used in ecommerce and subscription-based businesses to allow flexibility and product substitutions without canceling the order.

Why is SKU swapping important?

SKU Swapping helps maintain customer satisfaction when preferred products are out of stock, discontinued, or being upgraded. It also enables dynamic product offerings, such as personalized monthly subscription boxes, where the SKU can be swapped each cycle based on user preferences or behavior.

How does it work?

For example, in a subscription box service, if a user decides to switch their product from “SKU-A” to “SKU-B” for the next cycle, the system performs a SKU Swap, updating the subscription to reflect the new product.

Example of SKU swapping

A dog food subscription swaps SKU-123 (“Chicken Meal 5lb”) with SKU-456 (“Salmon Meal 5lb”) for the upcoming order after the user updates preferences.

To implement effective SKU Swapping, ensure your backend system supports dynamic SKU mapping, inventory availability checks, and clear communication to customers about the swapped item.
