“SKU” is an abbreviation of the phrase “Stock Keeping Unit” and refers to a code that is used to identify a product, much like a barcode or a part number, and is essential if you want to be able to track and manage your stock quantities between ChannelGrabber and your channels.
When an order comes into ChannelGrabber from one of your channels, ChannelGrabber uses the SKU to identify which product or variation has been ordered, and adjusts the relevant stock level(s) on your Products page automatically. If your stock management is active, ChannelGrabber will then push a stock update out to all channels where that SKU is listed, making sure that all your stock levels on all your channels are accurate and synced with each other.
Every unique item in your inventory must have a unique SKU, and any variation listings must also have a parent SKU, so that the variations have a SKU to be grouped under.
If the same item is listed on multiple channels, or multiple times on one channel, then every occurrence of the same item should have the same SKU, so that ChannelGrabber knows it is the same product and can match them up for stock management purposes. It does not matter if the title is different, as long as the SKUs match.
If your products and variations do not all have the correct SKUs, then ChannelGrabber's stock management feature will not be able to work effectively for you.
What Makes A Good SKU?
If your products come with unique barcodes or part numbers, you can use those as a SKU, as long as every product and variation has a unique one. If you manufacture your own products, or simply don’t have unique identifiers from a supplier, then you will need to create your own SKUs.
A sensible approach is to create a SKU that can identify the product without you needing to see the title or other information
Keep it concise, as some channels limit the number of characters in a SKU
Avoid starting or ending as SKU with a zero, as this makes working with SKUs in spreadsheet very difficult as some data programs remove zeros from the beginning or end of fields. It’s also a good idea to avoid ambiguous characters such as I, L, O - where it’s hard to tell whether it’s a number or a letter, especially if using lowercase letters.
Avoid the use of spaces in SKUs, try and use a dash ( - ) or underscore ( _ ) instead
Avoid the use of special characters such as “ & / * £ $ % etc. It’s best to just stick to letters, numbers, dashes and underscores
Ensure that the parent sku of a listing differs from any variation SKU(s). On some sites, such as eBay, matching skus here will prevent stock being updated correctly as the Channel fails to identify exactly what needs to be changed.
Consequences Of Bad SKU Management
Missing SKU: ChannelGrabber will not know which products are the same and therefore will not be able to link the same product when listed on different channels/multiple times on the same channel. The system will not be able to import your listings, or update stock levels when an order comes in, as there will be no SKU on the order or in ChannelGrabber to identify the product by.
Duplicated (non-unique) SKUs: ChannelGrabber will think that any products with the same SKU are the same product, and therefore multiple different products will be treated as one product. This means that incorrect stock levels will be sent to the channels once stock management is activated and could result in overselling or underselling.
Where Do I Add SKUs?
Most channels allow you to add SKUs to your products, but different channels use different terminology, so you may not always be able to find a “SKU” field. Look for SKU, Product Code, Custom Label, Product ID etc.
You need to add the SKUs on the sales channels directly - they cannot be added via ChannelGrabber.
Amending And Importing Existing Products From Your Channels
Products can be downloaded from your channels into the Import Listings section even if they are missing SKUs when you initially connect your channels, as ChannelGrabber can use the Listing IDs to separate them, but before you can import them or stock management can be effectively activated, SKUs will need to be added on the channels directly, then the items re-downloaded and then imported into ChannelGrabber's main products page before stock management can be effective.
If you have items on ebay, Amazon and a webstore for example, you will need to ensure that the SKU matches for each matching item on all three channels. Seeing as SKUs cannot be changed on Amazon without deleting and re-listing the product, we suggest that you use the Amazon SKU and copy that into the Custom Label field on ebay and the relevant SKU field in your webstore, to ensure that all SKUs match and the products can be merged when imported into ChannelGrabber. If an item is only listed on one channel, simply add your own SKU on that channel and re-import it.
