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.
A whitelabel auction platform for modern auction houses
Branded online auctions with AI valuations, secure bidding, and automated admin, without building the platform yourself. 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.
Whitelabel live pages
Public auction pages served under your own brand — custom logo, colours, and (optional) custom domain. 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.
Timed online auctions
Schedule timed auctions, manage status transitions (draft → scheduled → live → ended), and automatically settle hammer prices on close.
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, audit log on every admin action, rotated secrets, encrypted TLS 1.3, 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.
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
- ✓Audit log on every admin action (invites, status changes, payments)
- ✓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.
On the roadmap
What's coming next
Customers on the platform today help shape the priority. Here's what we're building toward.
Connectors
List a lot on other marketplaces in one click to boost sell-through. More buyers, less manual cross-posting.
Advanced analytics
Sell-through rates, bidder behaviour, category-level revenue, seasonal trends — the numbers you need to plan the next season.
CRM sync
Push buyers and consignors into your existing CRM (HubSpot, Pipedrive, Salesforce, Twenty) automatically so your team works from one contact list.
Live floor auctions
Clerk-driven hybrid auctions so floor + online bidders compete in the same sale.
Bidder mobile app
Branded bidder app with push alerts on outbid, auction start, and won-lot notifications.
Multi-language live pages
Serve the same auction in the bidder's language without duplicating your catalogue.
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?
+
Today we support timed online auctions with optional reserve prices and buyer's premium. Live floor auctions with clerk-driven bidding are on the roadmap for hybrid auction houses.
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.
