Portal is terrible, customer service is non-existent for suppliers, ticket system does not work and the ticketing staff is awful - bad attitudes and never a favorable solution. Pricing on our products shifts like crazy, and for unknown reasons. You have to check the promo manager in the portal multiple times a day as they try to sneak in promotional pricing which only deducts from your cut. Margin is just not present on Wayfair, they are a very shady "partner" who uses their locked in portals to literally steal/extort money from the seller. Even our partner rep takes weeks to respond and never provides a favorable resolution. They owe our company 6k+ in underpaid POs which we have repeatedly sent to them and have been ignored.
