What makes an EU compliance report actionable for a small ecommerce seller?

I am preparing to launch ComplyFolio, a free workflow that turns a product page into GPSR readiness gaps, supplier evidence requests, listing-ready fields and an evidence pack. The central product question is not how to make another compliance score; it is which output saves a seller time immediately. For people working with ecommerce listings: would you value a clearer missing-field checklist, a supplier follow-up message, a Shopify metafields CSV, or a reusable multi-SKU evidence workspace first? I am especially interested in where supplier back-and-forth currently breaks down.
