What Online Auction Software Has to Do

A bidding page is the visible ten percent. The rest of an online auction is registration, cataloging, bid handling, invoicing, settlement and the client record that ties it together. Circuit covers all of it in one system on your website.

Bidders Register With You

Registration, approval, bidding limits and paddle numbers happen on your domain. The bidder list is yours, in your auction house CRM, and no marketplace emails your buyers about someone else's sale.

Timed and Live Formats

Timed auctions with staggered closing and automatic bid extensions, and live auctions with a clerk console and real-time online bidding against the room and phones. One bidder account for both.

Absentee and Maximum Bids

Bidders leave maximum bids that the platform executes on their behalf, in timed sales and against the live call. Bids received by mail, email or phone are entered by staff into the same system.

Invoicing and Settlement Included

Invoices go out automatically when the sale closes. Payments, shipping and consignor statements are tracked on the same records, so the sale is settled without a second system.

Online Auction Software Features

Everything between consignment intake and the consignor's payout

AI Cataloging

AI auction cataloging drafts lot descriptions and estimates from photos and notes, keeps your house style and translates the catalog into 40+ languages.

Real-Time Online Bidding

Online bidders see the current bid, the increment and the clerk's call as it happens, on desktop and mobile, with no app to install.

Built-In CRM With Email Tracking

Every bidder and consignor is a client record with bidding history, interests, invoices and statements, and every email logged with open and click status.

Invoicing, Payments & Settlement

Buyer invoices with premium, tax and shipping. Card and bank payments. Consignor statements and payouts from the same sale data.

Your Brand, Your Domain

Delivered white label through the WordPress auction plugin or on a custom site. Bidders never see a marketplace logo.

Multi-Currency, 40+ Languages

Catalogs, bidding, invoices and statements in the bidder's language and currency, for auction houses selling to collectors worldwide.

Online Auction Software vs. an Auction Marketplace

Marketplaces bring bidders and keep them, and charge a percentage of hammer for the privilege. Online auction software on your own website changes who owns the relationship and what the sale costs.

No Commission to a Marketplace

Circuit is priced as a subscription, with a small commission on online bids on the standard plan and none on enterprise. A marketplace takes a percentage of every online hammer, plus a fee from your buyers.

The Bidder List Is Yours

Registrations, bidding history and email engagement live in your CRM. Read our guides to LiveAuctioneers alternatives and AuctionFlex alternatives for the full comparison.

Marketplace for Reach, Not for the Sale

Auction houses on Circuit often still list a catalog on a marketplace for discovery, and invite those bidders to register directly for the next sale. The share paid in commission falls with every sale.

One System, Not a Bidding Page Plus a Back Office

Cataloging, bidding, CRM, invoicing and settlement are one platform. There is no export from the bidding site to the accounting spreadsheet after every sale.

Online Auction Software for Every Specialist Category

The same platform, configured for the cataloging fields, grading standards and compliance rules of each category. Browse all collectibles categories, or start with the most common.

Fine Art

Provenance tracking, condition reporting and artist database.

Coins

PCGS and NGC grading, variety tracking and pedigree documentation.

Firearms & Weapons

Serial tracking, historical classification and FFL management on the client record. See our guide to GunBroker alternatives.

Stamps

Scott catalog integration, grading tools and postal history tracking.

Online Auction Software FAQ

What is online auction software?

Online auction software lets an auction house take bids over the internet, either in a timed sale where lots close on a schedule or in a live sale where online bidders compete with the room and phones in real time. A complete system also handles registration, cataloging, invoicing, settlement and client records, not just the bidding page.

Does online auction software replace a marketplace like LiveAuctioneers or HiBid?

It can. Online auction software runs the sale on your own website, where bidders register with you and no commission is paid to a marketplace on hammer. Many auction houses run the sale on their own platform and still list on a marketplace for reach, inviting those bidders to register directly for the next sale.

Can I run both timed and live auctions online?

Yes. Circuit runs timed auctions with staggered closing and automatic bid extensions, and live auctions with a clerk console, real-time online bidding, phone bidder cards and absentee bid execution. Bidders use one account for every format.

Do I need a developer to set up online auction software?

Not with Circuit. It installs as a WordPress auction plugin on your existing website, or on a custom site, and the auction house is running sales in days, not months. No technical skills are required to catalog, run and settle a sale.

How do bidders pay and how do consignors get paid?

Invoices are generated automatically when a sale closes, with buyer's premium, taxes and shipping applied. Buyers pay by card or bank transfer. Consignor statements and payouts are generated from the same sale data after the invoices are settled.

Is online auction software suitable for specialist collectibles?

Circuit is built for auction houses selling collectibles: fine art, antiques, coins, stamps, watches, books, cards, militaria and firearms among others. Each category has its own configuration for cataloging fields, grading and compliance, including FFL management for firearms.
