Where each one falls short

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

Fluxx

  • Configuration flexibility means the system does very little until someone configures it, and foundations without a dedicated systems administrator end up paying the vendor or a partner for every change.
  • Implementation commonly runs four to eight months and is priced separately from the subscription, so first-year cost is far above the annual licence figure.
  • No pricing is published and quotes scale with assets under management, which means two foundations making the same number of grants can be quoted very differently.
  • The card-based interface is unfamiliar to new users and reviewer adoption suffers without training, which matters because trustees use it a few times a year and forget between meetings.
  • Reporting is capable but the report builder is technical, and many foundations end up exporting to a spreadsheet or a BI tool for board-ready output.

Kindful

  • Kindful's own site now states that Kindful is a Bloomerang product and directs visitors to demo Bloomerang instead
  • The Bloomerang Giving Platform starts at $242 per month billed annually
  • Bloomerang Fundraising starts at $40 per month billed annually but must be purchased as part of a bundle with Bloomerang CRM
  • All plans are annual; there is no month to month option
  • Pricing is constituent based, so the bill rises with the size of the donor database
  • Only a starting price is published and the actual figure comes from contacting sales

Yes, for applicants. It is the submission portal, and funders pay for Grantmaker.

By quote, scaling with assets under management and grant volume. Implementation is a separate professional services fee.

Kindful: Does Kindful offer transaction fees for donations?

Transaction fee information is not disclosed on the website. Contact Kindful sales for details on payment processing costs.

Source
Fluxx: Can we configure Fluxx ourselves?

Yes, that is the point of it. But it requires a trained internal administrator; foundations that do not appoint one become dependent on paid services.

Fluxx: How long does implementation take?

Typically four to eight months for a multi-programme funder, driven mostly by how long the foundation takes to agree its own process.
