Silent Auction Software for Nonprofits That Keeps Every Dollar You Raise
Replace paper bid sheets with mobile bidding. Run in-person galas, virtual events, or hybrid fundraisers — with paddle raise, fund-a-need, outbid alerts and instant checkout, all on software you own. One-time purchase. No per-event fees. No commission on donations raised.
What Is Silent Auction Software?
Silent auction software is a digital platform that replaces paper bid sheets with mobile bidding. Donors bid from their phones — at your gala, from home, or anywhere in between — while organizers manage the entire event from a single dashboard.
Unlike traditional paper auctions (clipboards on tables, illegible handwriting, messy manual tally at the end), silent auction software handles the full event workflow: guest registration and check-in, branded item catalog, real-time bidding with outbid notifications, paddle raise / fund-a-need campaigns, automated invoicing, instant credit card checkout, and post-event donor reporting.
For most nonprofits, the result is the same story: higher final bids, faster checkout lines, and significantly more revenue per event — with a fraction of the volunteer burden.
Paper Bid Sheets vs. Mobile Bidding
| Final bid prices | Pushed up by outbid alerts |
| Checkout time | Minutes → Seconds |
| Outbid alerts | Automatic text/email |
| Remote donors | Fully supported |
| Volunteer hours | Cut in half |
Modernize Your Fundraising Event
Everything you need to run a professional silent auction — for in-person, virtual, or hybrid events.
Mobile Bidding
Donors bid from their own smartphones — at the gala, at home, or on the go. No App Store download needed; it's fully web-based and mobile-responsive.
Outbid Notifications
Instant SMS and email alerts when a donor has been outbid. Donors who get outbid come back and bid again, which is where most of the extra money in a mobile auction comes from.
Paddle Raise & Fund-a-Need
Run live paddle raise campaigns alongside your silent auction. Pre-set donation levels, thermometer displays, and real-time donor recognition on the big screen.
Text-to-Give & Text-to-Bid Custom
Want donors to bid or give by sending a text message? We build text-to-give and text-to-bid as custom work, typically $1,000 to $10,000 one time.
Instant Checkout
Pre-authorized credit cards are charged the moment the auction closes. Donors leave with their items, a digital receipt, and no line to stand in.
Live Leaderboards
Project real-time bidding activity, top donors, and fund-a-need progress on venue screens. Drives social proof and late-event bidding surges.
The Complete Event Workflow — From Planning to Thank-Yous
Every stage of a silent auction, unified on one platform.
Pre-Event Setup
Bulk import items via CSV, upload photos, set starting bids and reserves, create categories, configure sponsors, and preview the branded catalog before launch.
Ticket Sales & RSVP Custom
Online ticket sales, guest lists, dietary preferences and table assignments can be added to your auction site as custom work, so guests register and bid in one place.
Rapid Event Check-In
Guests check in by scanning a QR code or giving their name. Credit cards are pre-authorized on arrival — no line, no hold-up, no chaos at the door.
Live Mobile Bidding
Donors bid from their phones with proxy/max bids, watchlists, outbid alerts, and item-specific QR codes that jump them straight to the bidding page.
Paddle Raise Moment
Pause for the fund-a-need ask. Donors respond from their phones; the big-screen thermometer fills in real time; donor names scroll as gifts come in.
Instant Checkout & Reporting
Winning bidders are auto-charged, receipts emailed, items released. Post-event reports are ready instantly — donor list, tax receipts, total raised, top items.

An Online Silent Auction Platform on Your Own Website
Not every silent auction needs a ballroom. Many nonprofits now run online-only auctions over five to ten days, and some keep one open all year.
With our software, an online silent auction runs on your own domain under your own name. You share one link by email and social media, donors register once, and every item has its own page with photos, a starting bid and a reserve if you want one. Proxy bidding lets donors set a maximum and walk away, and soft close extends an item when a bid comes in during the final minutes, so last-second sniping doesn't decide the result.
When the auction ends, winners are charged and receive their invoice automatically. Every bidder stays in your own database, ready for your next appeal, instead of on a vendor's platform.
Online Auction Essentials

| Bidding | Proxy bids and Buy It Now |

Our Standard license is $899 once, plus your own hosting. Over 5 years that's roughly a tenth of the per-event cost.
