Hello! We run a large charity event every year with approx 700 people in the room, and around 100 silent auction prizes and also raffle tickets, and we use Gala Bid. I cannot fault them.
They had a representative there on the night and also offer prizes for your silent auction with a fixed reserve. If you don’t go over reserve you dont pay anything. Anything over reserve you keep the profits! You can customize your page to your event theme and they have great assistance before, during and after the event. Happy to chat further if you would like. Kind regards.
