I was a top professional seller on Tradesy until Vestiaire Collective bought them out. My Tradesy listings were transferred to Vestiaire and over 100 did not transfer which had to be manually relisted. The ones that did transfer, over 500 had listing errors and I am unable to fix them myself. Vestiare ALWAYS pays late. I have to beg my Proseller manager for every single payment. My sales on Vestiaire compared to Tradesy have dropped by 90%...yes you read that correctly. There is zero customer service at Vestiaire. The website is lackluster and very difficult for a Proseller to manage inventory. Listing on Vestiaire takes over 20 minutes per item which is too long for Prosellers. The marketing of the website is very poor. The strange puppets featured on the website until a month ago were creepy. There is really nothing interesting about the Vestiaire website that draws you in and it's very stale. This has been a disaster.
