I only want to offer (already) known products on a marketplace. Do I need to enable product synchronization?

If you only want to offer products that are already known in the marketplace, you don't always need to use product synchronization.

In fact, this question is similar to this article, where we explain when you do or do not need product mapping. The product synchronization we are talking about here sends these product mappings to the marketplace.

So when you don't need mappings, you don't need to enable that synchronization either.
