Webcast auction software for live sales with online bidders.
Broadcast your live auction online and let remote bidders compete with the floor in true real time. Unovance Global pairs low-latency simulcast video with auctioneer-controlled clerking — on a branded platform you own.
A webcast auction takes the energy of a live floor sale and opens it to the world. As the auctioneer works the block, a video simulcast carries the call, the cadence, and the item itself to bidders anywhere — and those online bidders compete against the room in true real time, not on a delayed feed.
That synchronization is what makes the format work. Floor bids and online bids land in the same contest, the auctioneer and clerk stay in full control of the block, and the hammer falls once for everyone. It is the right format when your buyers are spread across regions but the live sale is still the heart of your business.
With Unovance, the entire event runs on a platform you own. The same system handles cataloging, clerking, invoicing, and settlement, and the bidders you attract become your audience — your brand, your data, your buyer relationships — rather than a marketplace's.
Everything you need to run a live sale online.
Online bidders vs. the floor
Remote bidders see the live HD video stream and the auctioneer's call, then bid in true real time against everyone standing in the room — one synchronized contest, not a delayed feed.
Auctioneer-controlled clerking
Your clerk drives the block: open and close lots, take floor bids, acknowledge online bids, and record the hammer price the instant the lot sells. The auctioneer stays in command.
Low-latency simulcast video
Stream the rostrum, the ringmen, and the item itself so distant buyers experience the cadence of the sale and bid with confidence on what they can see.
Catalog, invoicing, and settlement
Pre-sale cataloging, live lot advancement, post-sale invoices, buyer's premium, and consignor settlements all flow from the same system that ran the event.
Frequently asked questions
What is a webcast auction?+
A webcast auction is a live, auctioneer-led event broadcast online so remote bidders can compete with the floor in real time. As the auctioneer calls each lot, online bidders watch the video simulcast and place bids that go head-to-head with bids from the room — the highest bid when the gavel falls wins.
How is a webcast auction different from a timed online auction?+
A timed auction runs on a countdown clock with no live auctioneer; bids accumulate until the lot closes. A webcast auction is a real, live event with an auctioneer calling lots in sequence. The energy, pacing, and on-the-spot competition between floor and online bidders are the whole point of the webcast format.
Do bidders need to attend in person?+
No. The webcast format exists precisely so buyers can participate from anywhere while the auctioneer runs a live floor sale. Online and in-room bidders compete on equal footing, and your audience is no longer limited to who can travel to the venue.
Can I run webcast auctions alongside other formats?+
Yes. Webcast is one of 22 formats on the Unovance platform. You can run live webcast events, timed online sales, and sealed-bid auctions from the same branded platform — keeping your brand, your bidder data, and your buyer relationships under your ownership.
