Frequently asked questions
What is Selloff?
Selloff is web-based management software for auction houses. It covers the whole cycle in one system: clients and marketing (CRM), consignments, cataloguing and lot descriptions, sales and bidding, invoicing, payments, shipping and accounting.
Who is Selloff for?
Auction houses of every size, and particularly specialist houses — coins and banknotes, stamps, fine art and antiques, autographs and manuscripts, fashion and luxury. It is used daily by auctioneers, cataloguers, front-desk, accounting and shipping teams.
Does Selloff work with online bidding platforms?
Yes. Selloff exports catalogues to Drouot and Interenchères, imports absentee bids from Sixbid, NumisBids, Philasearch and Biddr, as well as bidders and results from Biddr and Drouot, and runs live online bidding through Redpoint or its own live auction module. See the integrations page for details.
Which languages does Selloff support?
The interface is available in English, French and German. Each lot has an alternative heading and description, for example for a second language, and documents such as invoices and letters can be sent in each client’s language.
Can we migrate our existing data?
Yes. Contacts can be imported from spreadsheets, and the Selloff team helps you plan the migration of clients, lots and history from your current tools during onboarding.
How is Selloff priced?
Pricing depends on the modules you use and the size of your house. Request a demo and we will prepare a proposal based on your sale types and volumes.
