Online auctions for auction companies
A 500-lot sale drafted in 20 minutes, not 30 hours.
Photograph each lot on your phone. Catalot's AI writes the title and description, reads makers' marks and model numbers, and picks the category. Your staff review and publish. Then bidding, payment, pickup, shipping and consignor settlement run in the same place.
1. Shoot
The capture app numbers lots as you go, on as many phones as you have helpers. Add a voice note for condition or where it sits.
2. Draft
AI drafts each lot from its photos and notes: title, description, category, size and marks. It only fills what you left empty.
3. Review and publish
Approve drafts on one screen, fix what needs fixing, and publish. Lots close one after another with soft close.
Everything after the catalog, too
Pickup
Buyers book pickup slots; check-in by QR code on pickup day, with a receipt for every handoff.
Shipping
Ship in-house with labels printed from the invoice, hand off to a partner shipper or an outside service, or pickup only.
Consignor accounting
Commission tiers, fees and settlement statements, with a portal where consignors follow their items from proposal to payout.
