Product configurators, CPQ, and PIM often appear in the same ecommerce technology stack.
That can make them seem interchangeable. They are not.
Each system has a different primary responsibility, although their capabilities can overlap. Understanding the difference between a configurator vs CPQ vs PIM can help ecommerce teams avoid duplicated technology, disconnected product data, and confusing buying experiences.

PIM manages the information that describes the product.
A product configurator helps buyers explore and create valid product configurations.
CPQ makes configurations commercially valid through pricing, approvals, and quoting.
Here is how those roles differ and how the systems can work together.
