BiddingOwl

BiddingOwl is a specialized fundraising platform designed to help you manage charity auctions from start to finish. Whether you are running a small school fundraiser or a large-scale gala, you can transition your traditional paper-based bidding to a digital format. You can easily upload items, manage donor data, and track bids in real-time through a centralized dashboard.

The platform solves the common headache of manual checkout by automating the invoicing and payment process for winning bidders. You can choose between running a purely online auction, a mobile-only event, or a hybrid model that combines live and silent auction elements. It is built specifically for non-profits and schools looking for a cost-effective way to modernize their fundraising efforts without high upfront software fees.
