The short version
- Each has a real cost: OneCause pricing page names three tiers (Professional, Enterprise, Nationals) but publishes no dollar figures, requiring a request for the pay-as-you-go rate and a custom quote for Enterprise and Nationals, as of August 2026; Bloomerang pricing is based on the number of constituent records tracked, so the bill grows with the database rather than with usage
