Can sellers post their own auction listings on my site, and can I earn commissions from them?
Yes. Ultimate Auction supports a full seller marketplace model:
Online Auction Software (All Access): Includes a Seller Module with a front-end seller dashboard. Site owners can enable seller registration, and registered sellers can list their own auction products. You can collect seller commissions and automatically transfer payments to sellers’ bank accounts via Stripe.
Auction Plugin (Business & All Access): Seller listing is supported through integration with WCFM Marketplace, one of the most popular WordPress multi-vendor solutions.
Car Auction Software (Business & All Access): Includes seller registration and a seller dashboard with Stripe-powered bank account connections, plus an Offline Deal Facilitation feature that lets the site owner earn a buyer’s commission while buyers and sellers handle car handover and payment privately.
