The Auction Experts online auction platform
Auction Experts is a cloud-based online auction platform made of four parts: the bidder-facing auction website, the real-time bidding engine, the back-office auction management system, and the native mobile apps. They are supplied together as a hosted service, and every part can be branded as your own.

- The Manager Consignment intake, lot and catalogue management, bidder administration, invoicing, translations.
- Front-end API and integration API Build your own front end; connect your back office, ERP and accounting systems.
- Event system Subscribe to platform events. Build bidder profiles in your own CRM.
- White-label apps Native iOS and Android apps in your branding, full auction functionality.
- Authentication service OAuth 2.0, single sign-on across bidder-facing and staff-facing applications.

- Architecture and hosting How it runs on Azure, and how it handles the closing minute of an auction.

The parts most platforms do not have
Every claim below is one line in the full feature list; they are named here because almost no competitor has them, and buried in a list of 259 you might not look for them.
- Hall bidders, paddle registration and caller assignment for live sales, and phone bids alongside the room.
- Combination lots, sealed bidding and Dutch descending-price auctions, on the same engine as timed and live.
- VIES VAT validation and multi-country VAT and cost rules, including the margin scheme and intra-community supply.
- Consignor settlement produced in the same run as buyer invoicing, and Peppol e-invoicing.
- Catalogue printing with page layout and XML export to print design tools.
- The Lot-tissimo and Invaluable integrations, with bids tracked back to their channel.
- A translation module covering the website, the back office, the emails and every category name.
AI on the platform
Live today: the Auction Experts AI Connector. The platform exposes a Model Context Protocol (MCP) server, so an auction house connects the assistant it already uses — Claude, ChatGPT or any MCP client — straight to its own environment. Staff ask questions of their own auctions, lots, bids, bidders, costs and invoices in plain language instead of building a report, and the assistant reads a written guide to the data, so it answers with the auction house’s own definitions. This runs in production against real auction data; it is not a pilot.
Also live: the assistant does the work. With permission and a preview every time, it catalogues lots from their photos and descriptions, maps a consignor’s spreadsheet onto a lot type and imports it, creates auctions and puts them online, re-offers unsold lots, and writes translations, e-mail templates and settings. Bids, invoices and members stay with a person, in the back office.
We also use AI in our own onboarding, support and development, which is why a new customer environment now goes live faster than it used to.
Three ways to deploy it
Auction Experts is not a single fixed product. The choice does not change the back office.
- Hosted auction website. We supply the bidder-facing site on your domain, from a template with your branding or as a fully custom design.
- Added to your existing website. The auction section is embedded into the site you already run, so your main site stays where it is.
- Full integration. Your systems drive the platform through the REST API and you build your own front end on top of it.
Platform & integration
For your developer or IT lead.
- Hosting Microsoft Azure, dynamic scaling, 24/7 monitoring
- Integration REST API — lots, bidders, results
- Auth OAuth 2.0, single sign-on
- Events Webhooks on auction and lot events
- Content Built-in CMS, multilingual
Every auction type
The bidding engine supports timed online auctions, live auctions with remote bidding, sealed-bid auctions and Dutch auctions. Reserve prices, buyer's premium, per-lot bid steps, staggered closing and automatic extension are configured per auction or per lot.
