The short version

  • Each has a real cost: OneCause no transparent pricing published; all plans require contacting sales at 888-475-5214 or online form for custom quotes; 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.

Where each one falls short

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

OneCause

  • No transparent pricing published; all plans require contacting sales at 888-475-5214 or online form for custom quotes

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.

The vendor has been moving its products under the Societ brand, so you may see both names for the same platform during a sales cycle.

Yes, that is its clearest differentiator among donor CRMs. It is a licensed module, not part of the base product.

OneCause: Is there a Pay As You Go option?

OneCause indicates Pay As You Go availability is offered within the Professional plan, but specific costs require contact with sales.

Source
Sumac: Is pricing published?

No. It is quoted by module and organisation size, which makes like for like comparison harder than with published per contact products.

Sumac: Does it work for US charities?

Yes, though the vendor is Canadian and its receipting and support conventions are strongest for Canadian organisations.
