Consignment & Authenticators - Platform Pricing Decisions

Researching how luxury resale platforms price inventory. Looking for people with experience on the platform side Hey everyone! I'm doing independent research on pricing in luxury resale, specifically how platforms and authenticators decide what to list items at before they go live. I've already spoken with casual sellers and I understand the seller side pretty well. What I'm trying to understand now is the platform and professional side. How do you actually decide on a price? What information do you use? What takes the longest? And when something doesn't sell, how does that decision get made? If you work in consignment, authentication, or resale professionally or even do it seriously as a side business, I'd love to hear from you. Drop a comment or DM me.
