SKU stands for ‘stock keeping unit’. Creating SKU codes means you can assign unique names to your products. It’s especially useful if you’re listing variations of the same product - for example, a portfolio review session that can be booked for different lengths of time (30 mins, 45 mins, 90 mins, etc.). 

You can create a SKU code(s) in the ‘Inventory’ section of your Product Listing page. However, this isn’t mandatory so you can also leave this section blank.
