BidJS

What BidJS is
BidJS is a JavaScript embed for running timed and webcast auctions on an auctioneer’s own website and domain. Timed auctions support scheduled or staggered lot closings, max bids, and overtime extensions, and can include Buy Now, Make Offer, or private treaty listings. Webcast auctions combine floor, phone, and internet bids in real time. Auction teams can require identity verification, refundable deposits, or manual approval before bidders gain access. BidJS calculates buyer’s premium, creates itemised invoices, and connects with Stripe for deposits and Xero for accounting. Installation is available through WordPress or a JavaScript plugin for WordPress, Joomla, Drupal, custom-built sites, and other websites. Bidders use modern desktop, tablet, or mobile browsers without downloading an app; a branded native app is optional. Multilingual content and local currency formatting are supported. Bidder data can be exported. Pricing is on request, with plans at £200 a month for a developer sandbox, £300 a month on an annual contract, or £400 a month month-to-month.
Who it suits
BidJS is suited to fine-art, antiques, industrial, real-estate, agricultural, and charity auctioneers needing timed or live webcast sales on their own sites. It also fits teams requiring bidder controls, payment connections, and API access.

Verdict
BidJS combines auction scheduling, live bidding, bidder controls, invoicing, and website integrations in one embed. Its browser-based bidder access is broad, but costs and optional native-app work should be considered.
