Auction Engine
Create a branded foundation for selling assets through controlled auction and sales flows.
The Auction Engine connects assets, listings, buyer groups, bids, offers and commercial rules in one structured auction context. It helps organizations sell returned, used or surplus assets through their own portals while staying in control of access, pricing and buyer engagement.
With support for open, closed and invite-only auctions, organizations can manage who can view, bid on or negotiate for specific assets. Built on Purple Unity Foundation capabilities such as search, authorization, media, documents and integrations, it creates the trusted auction context needed to protect margin, improve residual value and build stronger buyer relationships.

Business benefits
Create more value from assets ready for resale
The Auction Engine helps organizations turn available assets into structured remarketing opportunities. By combining asset information, documentation, bidding and commercial context, teams can create more transparent sales processes and unlock higher residual value.
Automatic Bidding
Efficient Auction Participation with Max Bidding
Max Bidding allows customers to set their maximum price for auctions, enabling the system to automatically bid up to this limit. Ideal for open, running auctions, this feature simplifies participation by automatically placing incremental bids on the user's behalf. The process continues until the max price is reached, ensuring competitive bidding with minimal effort. Max Bids activate based on auction conditions, offering a streamlined and effective way to engage in the bidding process.
Automatic Auction - Lot extension
Sliding Window Feature for Dynamic Auction Bidding
The Sliding Window feature in Online Open Auctions introduces a dynamic element to the final moments of bidding. It activates a set period before a lot's scheduled end, allowing late bids to extend the auction duration. This strategic component, not available in Closed Auctions, enhances the bidding experience by keeping auctions competitive and lively right until the end. It's a game-changer for both bidders and auctioneers, adding excitement and unpredictability to the auction process.
