BiddingOwl vs PaddleUp

BiddingOwl provides online auction and fundraising tools for nonprofits, schools, charities, and other organizations. Organizers can run online, mobile, silent, live, or offline auctions and offer donations, admission and raffle tickets, Fund-a-Need, and paddle raises without separate paid add-ons. Bidders can follow items on a watchlist, set a maximum proxy bid, and receive SMS or email updates about outbids, wins, and events. Organizers can import items from CSV, export item data, manage or duplicate events, and retain their data; one login can manage multiple organizations and simultaneous auctions. Payments can be processed through Stripe or PayPal, or tracked as cash or check by manually marking invoices paid. Traditional silent and live auction services cost nothing; winning online or mobile bids incur a $5, paid once performance fee. Payment processor fees may apply. BiddingOwl is available on Android, iOS, and web. It offers weekday phone and email support and 24/7 critical emergency phone support.

PaddleUp provides event and fundraising software for schools and nonprofits, covering jog-a-thons, galas, auctions, and online sales. Campaign dashboards bring fundraising goals, settings, and related activities together. The platform supports live, silent, and online auctions, with mobile bidding; staff can use its iOS app to set up and monitor events in person. Ticketing covers registration and attendee check-in, and seating links tables and guests to the ticket roster. Bid sheet tools include printable sheets with QR anchors, photo uploads, and AI-assisted read-back against registered bidders. Stripe processes card and ACH payments, and the staff app can pair with Stripe Terminal Bluetooth readers for on-site sales. Organizations can use API keys and webhooks, with staff MCP tools for custom workflows and AI-assisted operations. The maker says sensitive attendee and bidder contact fields are encrypted with AES-256-GCM and per-organization keys managed through AWS KMS in production; service traffic uses TLS. Stripe handles card numbers and records payouts and refunds. There is no monthly platform subscription; Stripe processing fees apply, and AI tokens are pay-as-you-go.
