How to Set Up SKUs for Efficient Warehouse Operations in Norway

A successful online store is about more than just great products and marketing. Behind the scenes, logistics is the very heart of the business. For growing companies, the need for a structured system for product identification becomes critical. This is where the SKU (Stock Keeping Unit) comes into play. In this guide, we will walk through how to set up a professional SKU system that ensures seamless operations, whether you pack orders yourself or use a third-party logistics partner like Pick n' Pack.

What exactly is an SKU?

An SKU is a unique alphanumeric code used to identify a specific product in your inventory. Unlike a barcode (EAN/UPC), an SKU is something you create yourself for internal use. A good SKU tells you exactly what the product is, what color it has, and what size it is, without you needing to look it up in a registry. For us in Fredrikstad, handling thousands of shipments out of Østfold every week, good SKUs are the difference between efficiency and chaos.

Why is SKU structure important for your online store?

Without a logical system, warehouse staff will spend unnecessary time searching for items. This increases the risk of picking errors and dissatisfied customers. Here are the main benefits of a tidy system: * Faster picking: Warehouse staff immediately understand which product to retrieve. * Better inventory control: You get a full overview of which variants are selling best. * Easy scaling: It becomes much easier to add new product lines when the foundation is solid. * Seamless integration: When you connect your online store to our systems, correct SKUs ensure that everything works automatically.

How to build a professional SKU code

A good SKU should follow a fixed hierarchical structure. It should move from the general to the specific.

1. Start with brand or category

Use the first 2-3 letters to define the brand or main category. For example, "NK" for Nike or "SHO" for footwear.

2. Add product type

The next part of the code should describe what kind of product it is. For example, "RUN" for running shoes or "TSH" for t-shirts.

3. Include attributes (Color and size)

Finally, add variables that distinguish this exact product from others in the same series. For example, "BLUE" and "XL". Example of a finished SKU: `NK-RUN-BLUE-42` (Nike - Running shoe - Blue color - Size 42)

Best practices for SKU naming

When setting up your system, there are some pitfalls you should avoid. Here are our recommendations based on years of experience with warehousing and logistics in Østfold.

Avoid starting with zero

Some software (like Excel) may automatically remove a leading zero, which can ruin your entire dataset. Always start with a letter.

Keep it short but descriptive

An SKU should be between 8 and 12 characters. If it gets too long, it's hard to read. If it's too short, it's not descriptive enough.

Use hyphens as separators

Use hyphens (-) to separate the different parts of the code. Avoid spaces, slashes, or special characters that can cause issues in databases.

Never reuse an SKU

Even if a product is discontinued, the code should remain linked to that product in your history. Always create a new code for new products.

How SKUs affect your warehousing costs

If you have a messy system, it will take longer to receive goods, count inventory, and ship out orders. Time is money in the world of logistics. By having a clean structure, we at Pick n' Pack can offer faster handling. This is often reflected in more predictable costs for you as a customer. You can see more about our pricing models on our pricing page.

Implementing SKUs in your WMS

Once you have defined the structure, it must be entered into your e-commerce system (such as Shopify or WooCommerce) and your Warehouse Management System (WMS). When we receive goods at our warehouse in Fredrikstad, we scan the SKUs into our system. This gives you a real-time overview of your inventory levels.

Step-by-step implementation:

1. Inventory list: Create a list of all current products. 2. Logic definition: Decide which abbreviations will apply to your categories. 3. Update: Update the SKU fields in your online store. 4. Physical labeling: Ensure that products or their packaging have a visible SKU or associated barcode.

Frequently Asked Questions (FAQ)

Can I use the manufacturer's SKU?

We often recommend creating your own SKUs. Manufacturers may change their codes, or you could end up with two different suppliers using the same code by accident.

What is the difference between SKU and EAN?

An EAN (barcode) is a universal code that is the same for all retailers worldwide. An SKU is your internal code that is unique to your business and your warehouse.

How many SKUs can I have?

There is no upper limit, but remember that each unique SKU requires its own location in the warehouse. If you have too many variants with low sales, it can increase your storage rent.

Do I need an SKU if I only sell one product?

Yes, it is good practice to start with a system from day one. It makes it much easier the day you expand your range.
