🧭 Overview
An MSKU (Merchant SKU) is a unique identifier created by the seller to track and manage their products.
Unlike ASINs (which are assigned by Amazon), MSKUs are custom and fully controlled by you.
📦 What Does MSKU Do?
The MSKU helps you:
Track your inventory
Identify specific items
Organize listings within your system
Differentiate similar products
👉 Think of it as your internal label or product code
