Your Auction Platform Took 5% Before Stripe Even Charged You
If you're raising $200K+ annually, platform fees are quietly eating your donor intent. Here's your exit plan.
Custom auction platforms with live bidding, Fund-a-Need paddle raises, silent auctions, and automated donor receipts. Built on Supabase for real-time performance without SaaS percentage fees.
Your auctioneer calls a paddle raise and the platform stalls for three seconds. Momentum dies. Donors refresh their phones. Your Fund-a-Need total flatlines while the software catches up. A charity auction platform is a custom web app that runs silent auctions, live bidding, and hybrid galas -- mobile bidding, real-time updates, paddle raises, payment processing, automated tax receipts. Built custom, your nonprofit keeps full donor data ownership and cuts the 4–5% SaaS transaction fees that vanish before you see a dollar. On a $200K gala, that's $10K back in your budget before processing charges even start. Most organizations don't feel the loss until they try to switch vendors and discover years of bidder history locked behind an export paywall.

How We Build This Right
Every safeguard, built in from Day 1.
Real-Time Bid Engine
Supabase Realtime subscriptions push bid updates to every connected device in under 200ms. Outbid notifications fire instantly via push and SMS, keeping bidding wars alive.
Fund-a-Need Paddle Raise
A purpose-built live appeal interface with tiered giving levels, a real-time leaderboard, and a thermometer display. Your auctioneer controls the pace while donors tap to pledge from their phones.
Automated Donor Receipts
Stripe webhooks trigger tax-deductible receipt generation the moment payment clears. Every receipt includes the item's fair market value, amount paid, and your organization's EIN.
Row Level Security for Bid Privacy
Supabase RLS policies enforce sealed-bid and silent auction integrity at the database level. Bidders see their own bids and the current high -- never competitor amounts until close.
PCI-Compliant Payments
Stripe Elements handle card data so your platform never touches sensitive payment information. Pre-authorized cards at registration eliminate unpaid winning bids entirely.
Post-Event Analytics
Dashboards show bid velocity, item performance, donor acquisition cost, and Fund-a-Need conversion rates. Export everything to CSV or sync directly to Salesforce and Bloomerang.

Our Development Process
From discovery to launch. Quality at every step.
Auction Strategy & Schema Design
Week 1We map your event types -- silent, live, hybrid, Fund-a-Need -- and design the Supabase schema with tables for items, bids, donors, events, and receipts. RLS policies get defined here, before a line of code gets written.
Real-Time Bidding Engine
Week 2-3We build the Supabase Realtime subscription layer, bid validation logic in Edge Functions, and the Stripe pre-authorization flow. Every bid is atomic -- no race conditions, no duplicate charges.
Auction Frontend & Gala Tools
Week 3-5Next.js auction catalog, mobile bidding interface, Fund-a-Need paddle raise screen, event check-in, and an admin dashboard so your team can manage items and watch bids come in live.
Payments, Receipts & CRM Integration
Week 5-6Stripe checkout with automatic receipt generation, webhook-driven donor data sync to your CRM, and a post-event analytics dashboard with exportable reports.
Load Testing & Launch
Week 7-8We simulate 500+ concurrent bidders hitting the platform during a live auction close -- performance tuning, edge caching on Vercel, and 30 days of post-launch support to get you through your first event.
