If you need to specify the name of a company (yours or a company you work with), it's always helpful to create an abbreviation or acronym that can be utilized uniformly throughout all of your SKUs.  

Start with the broadest/ most important information about the product and narrow down to the more specific details from there. Here is a quick guide and a few examples that can give you an idea of how this should look.  

  Abbreviations can be used to keep ship simple, clean and easy to understand.

Including the hyphenation between each different element allows the mind to know which letters go together. This makes the SKU significantly easier to read.

Each abbreviation should not be just easy to read, it should be impossible to misunderstand. Some words, when abbreviated can lead to confusion.

Obviously, you want your SKUs to be as easy to understand as possible. By avoiding characters that could possibly cause confusion, especially when out of context, you can be assured that your SKUs clear.

Here is a chart of letters and numbers that are easily confused - especially when they are out of context or being viewed quickly.

A bundle that is sent to a client when they complete a challenge could be called simply completionbndl or something to that effect. This form of SKU creation isn’t as intuitive to newcomers as the first option, but they should be easily understood by someone with even a very rudimentary understanding of your company. The key to making the SKUs for these bundles effective, is that they always consist of the same things. If your bundle changes often, it’s best to stick with the first option (describing what is in the bundle/kit).
