Feature-by-feature comparison

Revision control and bulk item updates built in.	Single-lot entry or bulk CSV upload (up to 1,000 lots per file) with bulk image upload. AI drafting is a separate paid product, LotUp, from £29 per month. Translations are manual: export, edit in a spreadsheet, re-upload.
Bidder registration	Bidders register once on your own website and use the same account for timed, live and absentee bidding. Bidding limits and phone bidder cards are managed per client.	On the auction house's own site. Bidlogix states that every bidder who registers on a BidJS-powered site belongs to the auction house. Per-sale approval, refundable deposits and bidder suspension.
Live bidding	Clerk console with real-time online bidding, phone bidder cards and absentee bid execution, keeping room, phone and online bidders in sync.	Webcast auctions with a clerk console. Staff enter phone bids directly in the console; commission (absentee) bids are executed from it. Video streaming uses the auction house's own Vonage account.
