In Printify you can set your own variant specific SKU numbers for your products. You might be wondering, "What's an SKU number?". SKUs, or Stock Keeping Units, are codes that you (or others) can use to search and identify particular products in a system. In the world of Print-on-Demand, SKUs are a key part of managing inventory. While there is no stock that you need to keep track of per se, it is still very helpful to have a clear SKU system which you can use to find specific product variants more easily and which also allows you to identify the most popular variants in your store.
Below is a GIF showing what you need to do in order to set your own custom SKUs:
We also have a few suggestions about the best practices when defining your SKUs.
1. Make your SKUs easy to understand
Pay attention to easily identifiable aspects of a product: color, size, type, collection, etc.
For example, let's say you have a 2018 Summer Collection Ice Cream Tee in your store. In this case, for the Yellow / Large variant, a good SKU might be “S18T_ICE_Y_L”, where "S18T" stands for "Summer Collection 2018 Tee", "ICE" stands for the "Ice Cream" design, and "Y" and "L" stand for color and size variants respectively. It is always useful to arrange the product details in order of importance.
2. Don't use letters that look like numbers, spaces or symbols
You should stay away from letters like O, which can be mistaken for a 0. Also, definitely stay away from using capital 'i' and lower case 'L' ('I' and 'l' respectively), if you want to avoid any headaches. More importantly, it is not possible to use spaces when setting your customs SKUs in Printify, therefore, we suggest substituting spaces for "-" or "_", which is always the safest and best bet.
Lastly, there are a few limitations when setting the custom SKUs. As mentioned previously, spaces cannot be used when naming a custom SKU. In addition, it will not be possible to have duplicate SKUs for the same product. And finally, if you leave the custom SKU field empty and go ahead and save the changes, our system will auto-generate a random SKU for that particular variant. However, you can go back and change this at a later date, but all sales info for the auto-generated SKU will be saved separately from the new SKU.
