Live clerked auctions
Run real-time floor auctions (slagauktion) from a purpose-built auctioneer console — open, fair-warning, hammer. Online bidders compete live with the room, with proxy/absentee bids and soft-close built in.
The whitelabel platform for live & online auctions
Run live clerked auctions with real-time bidding and sub-second video, timed online sales, or hybrid sales where the room and online bidders compete — all under your own brand. AI valuations and automated admin included. Live in days, not months.

Auction software that sells for you, not for us
Most auction software looks like it was built in 2005 or forces your bidders onto a shared marketplace they've never heard of. Circulaire Auctions is different: every auction house is an isolated tenant with its own inventory, users, and branded public page. Your bidders see your business, not a third-party marketplace.
Behind the scenes you get a modern admin — clean inventory management, role-based access, audit log, and the option to pull AI-assisted valuations from Circulaire's pricing engine straight into a lot's estimate field.
- Your brand, your domain, your buyers
- AI-assisted valuations on every lot
- Automated admin — invites, catalogue, settlement paperwork
- Stripe-ready, plus custom payment providers on request
- Audit-logged admin actions

Everything an auction house needs — nothing it doesn't
The features that matter, built for how auction houses actually operate.
Sub-second live video
Stream the rostrum to remote bidders with near-instant WebRTC video (auto-falls back to low-latency HLS). Approved bidders watch and bid in the same view — no third-party stream, no plugins.
Timed & hybrid sales
Run timed online auctions, live floor sales, or combined auctions where floor and online bidders compete in one sale. Automatic status transitions and settlement on close.
Multi-tenant by design
Every auction house gets a fully isolated dashboard, inventory, consignors, and auctions. No cross-tenant data leakage — enforced at the query layer, not hoped for.
Whitelabel live pages
Public auction pages under your own brand — logo, colours, fonts, and an optional custom domain. Fully localised: English, Danish, Swedish, Norwegian and Hebrew (right-to-left) ship today, and we add any language you need. Bidders see you, not us.
Inventory & consignor management
Catalog lots with images, estimates, reserves, and start bids. Track each lot's lifecycle from intake to sold. CSV import for bulk onboarding.
AI-assisted valuations
Every lot can pull a market valuation from Circulaire's pricing engine — the same AI that powers our real-time pricing platform across 100+ marketplaces.
Flexible payments
Stripe out of the box — card + SEPA — and we can plug in your existing payment provider if you already have one. Buyer's premium, VAT, and commission calculated server-side on every hammer.
Administrative automation
Invites, catalogue entry, lot status transitions, consignor statements, buyer invoices — all generated for you. Less clicking, more selling.
Security you can point to
Tenant isolation, a tamper-evident hash-chained audit ledger on every admin action and live-auction event, rotated secrets, encrypted TLS 1.3, and rate-limited auth.
Invite-based onboarding
Enroll your staff via email invite — they set their own password, you keep control of who has access. Password reset + change-password flows built in.
Marketing built in
Sync your bidder list to Mailchimp (consent-aware), auto-tag the winners of every sale, and spin up a house-branded promo email for a live auction in one click — featured lots, images and CTAs, ready to send.
Bidder verification & trust
Optional BankID / MitID identity checks, manual bidder approval gates, per-house and platform-wide bans, plus reCAPTCHA and bot heuristics — so you know who's in the room.
Nordic bookkeeping & settlements
SIE 4 export, Dinero integration, and netto/deferred consignor accounting out of the box — plus branded consignor settlement statements with commission, fees and VAT calculated for you.
Integrations, and growing
Stripe, Mailchimp, Dinero, SIE 4 bookkeeping, Shipmondo shipping and BankID/MitID are wired in today — and because every integration is just an adapter, we add new ones on request, usually within days.
From kickoff to first hammer
Four steps — most customers are live within a week.
- 1
Enrol your auction house
We create your tenant, invite your admins by email, and help configure currency, buyer's premium, and commission defaults.
- 2
Brand your live page
Upload your logo and colours. We wire your public auction URL — either a slug on auctions.gocirculaire.com or your own custom domain.
- 3
Catalog your inventory
Add lots manually or via CSV. Upload images, set estimates and reserves. Optionally pull AI-assisted valuations on each lot.
- 4
Schedule & go live
Create an auction, pick lots, set times, publish. Bidders register, place bids, and the platform handles settlement on close.
Built for lot-based sellers
If you run auctions — or wish you did — this is probably for you.
Auction houses
Small to mid-sized houses that want a modern online presence without building it themselves.
Specialty dealers
Watches, jewellery, fine art, design, collectibles — anywhere lot-based selling beats fixed-price listings.
Galleries & estates
One-off or recurring estate sales where you need branded live auctions with minimal operational overhead.
Consignment businesses
Professionals who represent sellers and need consignor + commission workflows baked in.
Security & reliability
Built to be pointed at by your compliance team, not hidden from them.
- Tenant isolation enforced at every query — not just the UI
- Tamper-evident, hash-chained audit ledger on every admin action and live-auction event
- Optional BankID / MitID identity verification, bidder approval gates and bans
- TLS 1.3 in transit, encryption at rest, rotated secrets
- Rate-limited auth + password reset + invite acceptance
- Responsible-disclosure programme with public hall of fame
Powered by Circulaire's automation and valuation engine
Every lot can pull a second-hand market valuation on demand — sourced from 100+ marketplaces and validated by the same AI that powers the Circulaire Real-Time Pricing Platform.
Catalogue a watch, handbag, or piece of design furniture, and the platform suggests an estimate range, cites the comparables, and logs the valuation for audit. No more guessing — or waiting days for an appraiser.

Frequently asked questions
Still have questions? We're happy to walk you through the platform.
How long does it take to go live?
+
A new auction house can be enrolled and running its first timed auction within a week. Most of that time is spent collecting your first batch of inventory and tuning your branding — the software itself takes minutes to provision.
Do my bidders see Circulaire branding?
+
No. The public live page is whitelabelled — your logo, your colours, and optionally your own domain. We only appear in the footer if you explicitly want us there.
What auction formats do you support?
+
All of them. Timed online auctions; live clerked floor auctions (slagauktion) with real-time online bidding and a sub-second live video feed; and combined/hybrid sales where the room and online bidders compete in the same auction. Reserve prices, buyer's premium, proxy/absentee bids, and soft-close work across every format.
How does payment work?
+
Stripe is wired out of the box (card + SEPA). If you already use a different payment provider, we can plug it in — just tell us on the demo call. Buyer's premium and VAT are calculated server-side on each hammer, and consignor commission is tracked per lot with exports for accounting.
Can I import my existing inventory?
+
Yes. We offer CSV import with a column-mapper for your existing spreadsheet, and bulk image upload. For your first migration we do it with you, so there's no surprise when your first auction goes live.
What's the pricing model?
+
A flat monthly platform fee — one of the best-value auction platforms on the market. We do not take any percentage of hammer value. You keep every krona your auction earns. No setup fee, no long-term commitment — talk to us for a quote matched to your expected volume.
What integrations do you support?
+
Out of the box: Stripe (card + SEPA), Mailchimp for marketing and winner tagging, Dinero and SIE 4 export for bookkeeping, Shipmondo for shipping labels and tracking, and BankID / MitID for identity verification. Because each integration is a self-contained adapter, adding a payment provider, CRM or carrier you already use is usually a matter of days — just ask on the demo call.
