Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mightycause

  • No paid tiers or premium upgrade options available

Sumac

  • Pricing is not published at all, so a small organisation cannot compare Sumac against per contact priced competitors without committing to a sales process.
  • The interface reflects the product's age, and staff arriving from consumer grade software find navigation and data entry slower than in newer CRMs.
  • Holding client case notes and donor records in one database makes permission design a compliance obligation, and a misconfigured role can expose confidential client material to fundraising staff.
  • The integration catalogue is small, so payment, email and accounting connections outside the listed few mean manual export or paid custom work.
  • Modular licensing means the price rises in visible steps as programmes expand, and organisations frequently discover the module they need most was not in the original quote.
