SKU is the abbreviated form for Stock Keeping Unit, otherwise known as a product code. It is a unique identifier that makes it possible to find, search, and reference products from lists, invoices, order forms, etc. On TradeGecko, each variant of a product must have its own unique SKU.
When creating SKUs, keep them simple enough so that others will understand them. We recommend using the first area of the SKU to group the products together and use the last part, after the dash, for the unique values.
For example, if you sell hats 🎩 , your SKUs could look like this:
Sun Hat Red, model no.1 = SH01-R
Sun Hat Yellow, model no.1 = SH01-Y
Sun Hat Green, model no.1 = CM01-G
