Where each one falls short

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

Fundraise Up

  • The fee is a percentage of donations, so cost rises exactly as the product succeeds, and a single large gift routed through the checkout carries the same rate as a twenty pound one unless the agreement caps it.
  • It is a checkout, not a CRM, so it is always an additional cost on top of a donor database rather than a replacement for one.
  • Donor covered fee opt in rates vary widely by audience, so an organisation with an older or offline leaning donor base absorbs more of the fee than the sales model assumes.
  • Design control is limited to what the embedded component exposes, so brand teams that want full control over the giving experience will hit boundaries.
  • Live recurring gift authorisations are held in the platform, which makes leaving considerably harder than adopting, because migrating active mandates risks lapsing donors.

Mightycause

  • No paid tiers or premium upgrade options available

A percentage of each donation, plus separately billed card processing. There is no flat licence that insulates you from volume.

Active recurring authorisations sit with the platform and its processor, and migrating them is the part of an exit most organisations underestimate.
