Auction software that looks like your house — not a SaaS template.

Why specialist houses move off generic auction SaaS

Cookie-cutter platform that hides your house

Bidlogix, Auction Mobility, the various WordPress plugins — they all look the same. Your bidder sees a generic auction interface with your logo in the corner. For a specialist house competing on reputation, that's a slow erosion of brand. We build the bidder UX around your house, your category, your lot taxonomy.

Per-lot or per-hammer fees that scale with your success

The SaaS pricing model punishes growth. Big sale day means a big bill. We don't take a percentage. Fixed-price build, predictable monthly retainer, no per-lot rent.

KYC and AML that lags on high-value lots

When a six-figure bid lands, you need source-of-funds, sanctions screening, and signed terms — fast. Generic platforms either don't have it, or have it bolted on as an afterthought. We build KYC into the bidder onboarding so the work is done before the lot opens.

Integration with your accounts that nobody finished

Every sale should land in Sage / AccountsIQ / Xero as a proper sales invoice with buyer's premium, VAT margin scheme where applicable, and shipping lines. Most generic platforms produce a CSV your bookkeeper hates. We do it properly.

What's in a bespoke Intellix auction platform

Bidder-facing storefront & catalogue

Server-rendered catalogue (fast, SEO-indexable). Filterable by category, estimate, lot number, location, status. Lot detail pages with image zoom, condition reports, provenance, related lots, watch-list. Branded as your house, not us.

• Fast, SEO-indexable lot pages — Google can find every lot.
• High-resolution image pipeline with zoom and gallery.
• Condition reports, provenance fields, dimensions, weight, materials.
• Watch-list, saved searches, lot-ending notifications.

Bidding engine — timed, live webcast, hybrid

Server-authoritative clock. Anti-sniping auto-extension. Proxy / max-bid. Live webcast with low-latency video (Mux / Cloudflare Stream / AWS IVS). Auctioneer clerk interface for live sales (room / phone / online lots in one screen).

• Server-authoritative clock — no client-side bidding shenanigans.
• Anti-sniping extension (configurable per-house).
• Proxy / max-bid with hidden ceiling.
• Live webcast — 2–3s latency, server-synced.
• Clerk interface — room, phone and online lots in one calling screen.

KYC, AML & fraud screening

Every bidder verified before bidding above your configurable threshold. Onfido / Veriff / SumSub for ID + selfie. Card-AVS pre-auth on registration. Sanctions + PEP screening (Comply Advantage). Source-of-funds questions on high-value lots.

• ID + selfie verification at bidder onboarding.
• Configurable thresholds per category (art houses set higher than industrial).
• Sanctions, PEP and adverse-media screening.
• UBO checks for corporate bidders.
• Audit trail — who saw what, when, signed by which compliance officer.

Buyer's premium, VAT margin scheme & invoicing

Configurable buyer's premium (tiered, vendor-specific, lot-specific). VAT margin scheme for second-hand goods (where applicable). Hammer-fall triggers invoice generation in Sage / AccountsIQ / Xero with the right line items.

• Tiered buyer's premium with vendor / lot overrides.
• VAT margin scheme for art, antiques, second-hand goods.
• Auto-generated invoice with hammer + premium + VAT + shipping.
• Stripe / Worldpay / GoCardless / bank-transfer payment workflow.

Consignor portal & settlement automation

Consignors see their lots, watch live, get statements. Auto-generated settlement statements after each sale (gross hammer, vendor's commission, expenses, net). Optional purchase-invoice draft for your finance team to approve.

• Consignor login with lot status, watch-list, post-sale results.
• Auto-generated settlement statement (PDF + CSV).
• Vendor's-commission tiers, expense recovery, marketing fees.
• Draft purchase invoice into your accounting system for sign-off.

Comms, notifications & post-sale logistics

Outbid email + SMS + push. Won-lot invoice. Saved-search digests. Post-sale shipping coordination with specialist art handlers, equine transporters or generic couriers depending on the category.

• Outbid notifications (email + SMS via Twilio + push).
• Won-lot invoice with payment options and shipping selection.
• Saved-search digests; tease upcoming sales to opted-in bidders.
• Shipping handler integration (specialist art / equine / general).

Why specialist houses pick Intellix

• You own the platform. Source code, database, every pixel of CSS. No per-lot fees, no SaaS lock-in, no proprietary file formats. Hostable in your cloud if you want.
• No referral kickbacks. We're not a Stripe / Onfido / Mux reseller. Our recommendations are whatever's actually best for your category.
• Sale-day cover. We're in the room for your first live sale on the new platform. Dress rehearsal, rollback plan, hot-fix engineer on standby.
• Built to last. Boring, proven tech — React / FastAPI / Postgres. No 'next big framework' rewriting every 18 months.
• Live in the wild. See ballypatrickauctions.com for a public example of our auction-platform work.
