# Overview

Products are used in the ERP to represent objects, that are used in the work processes, ranging from materials, tools, office supplies, work equipment to finished and semi-finished products. They are used <span aria-level="1" class="yKMVIe" role="heading">throughout</span> most work processes, including purchasing and selling processes.

Every product is, when created, assigned a unique **SKU** (Stock Keeping Unit) number, that will be used to refer to this product within the system. All SKUs are required to be unique, duplicates are not supported.
