BidJS vs BidPro

BidJS is a JavaScript embed that lets auctioneers run timed and webcast auctions on their own websites and domains. Timed auctions can use scheduled or staggered lot closings, max bids, and overtime extensions; webcast auctions combine floor, phone, and internet bids in real time. Timed sales can also offer Buy Now, Make Offer, or private treaty listings. Auction teams can require identity checks, refundable deposits, or manual approval before granting bidder access. BidJS calculates buyer’s premium, creates itemised invoices, and supports Stripe deposit processing and Xero accounting connections. Installation options include WordPress and a JavaScript plugin for WordPress, Joomla, Drupal, custom-built sites, and other websites. Bidders can browse, register, and bid in desktop, tablet, and mobile browsers without downloading an app; a branded native app is an optional extra. The service supports multilingual content and local currency formatting, and bidder data can be exported. BidJS is made by Bidlogix, which says it began building auction technology in Brighton in 2008. Listed plans include a £200 a month developer sandbox, a £300 a month annual contract, and a £400 a month month-to-month option.

BidPro is a white-label online auction platform for auctioneers who want to run auctions on their own branded websites. It supports live, virtual live and timed auctions, with livestreaming that BidPro describes as having sub-second latency and says can connect to third-party platforms. Its AI cataloguing tool can generate lot titles, descriptions, estimates, opening bids and bid increments from photos. Auctioneers can import catalogues from Excel and match bulk-imported photos to lots using barcodes. Bidders can pre-bid or use automatic and absentee bidding, while increments can be configured to respond to bidding patterns. Auctioneers can require documents at registration and approve bidders before they participate. Marketing options include custom SEO tags and keywords, Google Analytics tags, and contact exports for bulk email or SMS providers. There is a free Bidder plan and a free trial. Pay As You Go is $65, paid once, with a 0.5% to 0.25% commission, excluding VAT; Monthly Contract is $750 a month, excluding VAT. The signup guide says charges depend on subscription type and users set up payment details with BidPro's payment provider.
