How does PIM help multi vendor maintain accurate product catalogue?

Basically, I’m wondering how Akeneo, Salsify, Pimcore, UnoPIM, or Informatica helps multi-vendor marketplaces keep their product catalogues accurate and up to date. Like, can they make sure all product details, images, prices, and specs from different vendors stay consistent, reduce errors, and save time? I want to know if they actually make managing tons of products from multiple sellers easier without constantly checking and correcting stuff manually.
