BiddingOwl vs Fish Auctions

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.

Fish Auctions is a free web service for clubs running auctions for fish, reptiles, amphibians, food cultures and other pet-keeping supplies. Clubs can hold traditional in-person auctions or run them online. Online bidding supports proxy bids, and an auction can extend when bids arrive in its final 15 minutes. Organizers can manage lots, set reserve and buy-now prices, add labels, and project lot pictures during in-person events. Auction creators can give other users admin permissions to add users, edit lots, and view or export invoices. The site generates invoices automatically, but clubs handle payment collection themselves. Square payments are available to approved accounts, and invoices can be exported for PayPal import. CSV exports include breeder-point information, and lot images can include YouTube links. The site says online auctions can accommodate 200–300 simultaneous users without slowdowns in practice; larger use may slow it. Direct person-to-person sales outside a club auction are not permitted.
