OneCause is built for fundraising events: galas, mobile bidding, and auction nights. Social Good Software runs giving on Blackbaud Altru, alongside membership and admissions. The dividing line is time: an event platform optimizes one big night; a cultural venue runs giving year-round on the Altru record.
One big night vs year-round giving
OneCause is genuinely good at the gala: silent auctions, mobile bidding, and paddle raises that make an event night run smoothly. What it is not is a year-round system of record. For a museum, zoo, or garden, giving happens all year and belongs on the same record as membership and admissions. OneCause gifts have to be reconciled back to your CRM after the event.
When OneCause is the right call
For an organization whose fundraising centers on galas and auction events, and that wants best-in-class mobile bidding for those nights, OneCause is a capable, purpose-built platform.
Giving that runs all year on Altru
Social Good Software ties donations to the Altru constituent record alongside membership and admission, so giving is continuous and tied to the donor’s membership and visits, not confined to event night.
