OneCause

What OneCause is

OneCause is a web-based fundraising platform for cause-driven organizations, serving groups from small grassroots nonprofits to large multi-affiliate institutions. Founded in 2008 and headquartered in Indianapolis, it provides tools for in-person, virtual, and hybrid events, online campaigns, auctions, donations, and peer-to-peer fundraising. Event capabilities cover ticketing, table management, sponsorship sales, check-in, auctions, raffles, and donation scoreboards. Its online fundraising tools include donation forms, recurring giving, giving sites, personal fundraising pages, SMS messaging, and campaign reporting. Donors can use Apple Pay, Google Pay, Venmo, PayPal, ACH, and donor-advised funds, while payment processing is handled separately. Peer-to-peer Professional and Enterprise plans list Mailchimp, Salesforce, and Luminate integrations; Essentials does not list them. API support is included with the Nationals event package, rather than Professional or Enterprise. OneCause states that it follows PCI data-security standards, encrypts stored sensitive personal information with AES-256, and uses TLS 1.2 or higher on pages capturing sensitive card data. Support includes weekday phone, chat, and email assistance, plus a knowledge base, tutorials, FAQs, customer success managers, webinars, professional services, and event teams. The company says it has joined Bonterra.

Who it suits

OneCause suits nonprofits that need one web platform for event fundraising, online giving, campaigns, and peer-to-peer programs. Its event and support services can serve organizations ranging from grassroots groups to large multi-affiliate institutions.

Limits

OneCause has no free plan. 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, and payment processing is separate.

Verdict

Pick OneCause if your organization needs web-based event and online fundraising with peer-to-peer tools and multiple giving options. Look elsewhere if you require a free plan, bundled payment processing, or API access on Professional or Enterprise.
