Indianapolis, Indiana, United States
What it is
OneCause is web-based fundraising software for cause-driven organizations, supporting events, online campaigns, auctions, donations, and peer-to-peer fundraising. Its event tools cover ticketing, table management, sponsorship sales, check-in, auctions, raffles, and donation scoreboards for in-person, virtual, and hybrid events. Online Fundraising includes donation forms, recurring giving, giving sites, personal fundraising pages, SMS messaging, and reporting. Listed payment options include Apple Pay, Google Pay, Venmo, PayPal, ACH, and donor-advised funds. Pay-As-You-Go starts at $200, paid once and adds a capped 5% pay-later fee on funds raised; Professional Auction & Event costs $2,995 a year as a flat subscription. OneCause has no free plan, and payment processing is separate. Mailchimp, Salesforce, and Luminate integrations appear in Professional and Enterprise peer-to-peer plans, not Essentials. API support is included in the Nationals event package but not Professional or Enterprise. OneCause was founded in 2008, is headquartered in Indianapolis, and says it has joined Bonterra.
