Is there a Product Information Management (PIM) system that doesn't require technical expertise?
Yes. Take a look at OneSila. It is specifically designed to integrate without technical knowledge. It's built for teams who want powerful tools at their disposal in minutes - not weeks or months.
You can use it to store all your product-assets: Titles, descriptions, SEO-info, attributes, images, files, video, etc.. and take care of your product destruction across a range of eCommerce sites and marketplaces. No need for developers to get involved.
