How webcast auctions work
Three bidding channels converge on a single lot in real time. BidJS orchestrates them seamlessly.
Floor bids
Your auctioneer handles bidding in the room as normal. The clerk marks floor bids in the BidJS console, and they appear instantly in the internet bidder view.
Phone bids
Staff taking phone bids enter them directly in the clerk console. Phone bidders are treated identically to floor bidders from a system perspective.
Internet bids
Online bidders connect via WebSocket and receive a live feed of every bid placed, with every update arriving in real time. They bid directly from their browser — no app, no plugin.
Webcast auction features
Real-time bid feed
Every bid — floor, phone, or internet — appears in real time over WebSocket.
Clerk console
A dedicated tool for marking floor and phone bids, advancing lots, and managing the live sale.
Internet bidder view
A clean, branded interface showing current bid, lot info, bid history, and a Bid button.
Bid notifications
Bidders receive instant notifications when they are outbid, keeping them engaged throughout the sale.
Video streaming
Webcast video is powered by Vonage. Auctioneers connect their own Vonage account during onboarding — the stream then starts directly from the clerk console in the browser, with no separate broadcast software needed.
