Fair closing rules that protect every bidder.
Configurable soft-close automatically extends auction end-time when bids land within a defined window — preventing last-second sniping while maintaining predictable close times with maximum extension caps.
The Problem
Hard close times unfairly penalize bidders who cannot react in the final seconds. Unlimited extensions frustrate bidders and create unpredictable timelines. Manual close management introduces human error and inconsistency across events.
The Solution
AuctionFlow's soft-close rules are fully configurable: extension window, maximum extensions, and final deadline cap. Rules apply per lot or per auction, execute automatically, and notify all bidders in real time when an extension triggers.
Capabilities
Configurable Extension Window
Define the time window before close that triggers an extension when a bid is received. Default is 5 minutes, but operators can set any duration from 1 minute to 30 minutes depending on lot value and auction format. High-value lots often use longer windows to ensure competitive bidding continues as long as interest is active.
Maximum Extension Limits
Set the maximum number of extensions per lot to prevent indefinite bidding. A lot configured with 3 maximum extensions and a 5-minute window will extend up to three times before the close becomes final. This creates a predictable worst-case timeline that operators and bidders can plan around.
Per-Lot Soft-Close Rules
Different lots within the same auction can have different soft-close configurations. Premium lots with high estimated values might use longer windows and more extensions, while commodity lots use shorter windows with fewer extensions. Rules are assigned during lot setup or applied by category template.
Real-Time Extension Notifications
When a soft-close extension triggers, all bidders watching that lot receive instant notification via WebSocket. The countdown timer resets, the extension count updates, and bidders see clearly how many extensions remain. This transparency builds trust and encourages continued participation.
Extension Cap and Final Deadline
Beyond maximum extension counts, operators can set an absolute final deadline after which no further extensions are possible regardless of bidding activity. This ensures every lot has a guaranteed final close time, which is essential for event scheduling and settlement planning.
Architecture
Soft-close logic executes within the bid validation pipeline as a before/after hook around the close mechanics. Custom soft-close behavior — such as staggered close times across lot groups or variable extension durations based on bid count — can be implemented via upgrade-safe hooks without forking the core close engine.
AI Copilot
The AI copilot recommends optimal soft-close windows based on lot value, historical bidder count, and category benchmarks. It identifies lots where aggressive sniping is likely and suggests extended windows proactively.
