OneCause review
Bottom line
OneCause is an event and auction fundraising platform that links galas, online campaigns, and peer-to-peer pages to a single donor record. Its clearest strength is the breadth of event tools, from ticketing and table management to mobile bidding and scoreboards, paired with support included at no extra cost. The main cost to watch is pricing, since most plans require a demo request and the pay-as-you-go option adds a 5% fee on funds raised, capped at a set amount. Nonprofits that run frequent auctions and events and want one system for tickets, bids, and donors should pick it.
What is OneCause?
OneCause is fundraising software for nonprofits that run galas, auctions, golf outings, and online campaigns. It puts ticketing, registration, silent and live auctions, donations, and sponsorships in one system, replacing the spreadsheets, paper bid sheets, and separate payment tools that event teams often juggle. It also covers year-round giving through online donation forms, giving sites, and peer-to-peer pages.
Day to day, event staff build an event, sell ticket packages with custom questions and promo codes, and group seated and unseated guests by table. On event day, guests check in with QR codes and bid through mobile bidding, while configurable scoreboards show progress during paddle raises and donation appeals. Staff can send automated and custom text messages to guests and supporters. Donor records collect every contribution and purchase across events, and post-event receipts can be configured. AI tools recommend items based on bidding activity and generate item descriptions.
The typical users are nonprofit development and event teams at schools, health and human services groups, arts organizations, faith-based groups, and foundations. Pricing has two paths. A pay-as-you-go option starts at $200 and applies a 5% pay later fee to funds raised, and that fee is capped. The Professional Auction & Event package is a flat $2,995 annual subscription with no percentage fee. Buyers request a demo to get a quote for their organization.
What sets OneCause apart is that it connects in-person events with online campaigns and peer-to-peer fundraising in a single platform, so a gala and a year-end appeal share one donor history. Support is included at no extra cost by phone, chat, and email, and an AI Guide is available around the clock. The capped fee on funds raised gives organizations a defined maximum cost for a campaign, which many event tools do not offer.
