Where each one falls short

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

Overflow

  • Crypto carries a 3 percent fee on top of the base rate, which makes it the most expensive channel on the platform at exactly the point where donors expect it to be cheap.
  • Card processing at 2.75 percent plus 30 cents on the entry plan is above what a church can get from a dedicated church giving processor, so using Overflow for routine weekly giving costs more than it should.
  • It is a giving channel, not a church management system, so contributions must be reconciled into your existing ChMS and finance software, adding a second monthly close step.
  • Stock and DAF fees are quoted as a 1 to 3 percent range with the actual rate depending on transfer route, so an organisation cannot forecast net proceeds precisely before the gift settles.
  • Non-cash gifts settle over days rather than instantly, and the amount received depends on the price at liquidation, so the receipted value and the cash landed will not match.

Subsplash

  • Card giving is 2.3% plus 30 cents and ACH 1%, deducted from each donation
  • The lower advertised rates of 1.9% and 0.5% require GrowCurve rather than being standard
  • No monthly price is published for the One or Enterprise packages, which are quoted on church size and usage
  • Reaching a quote requires contacting sales by phone

Overflow: Why give stock instead of cash?

Transferring appreciated shares avoids the capital gains tax the donor would pay on selling first, so the same after-tax cost produces a larger gift.

Subsplash: What does Subsplash One include?

Subsplash One is an all-in-one platform including websites, media hosting, apps, live streaming, giving, events, groups, messaging, volunteering tools, check-in, service planning, podcasting, and forms. Pricing varies by organization size.

Source
Overflow: Does Overflow replace our church management system?

No. It handles giving only and integrates with your existing ChMS.

Subsplash: What is the pricing for Enterprise?

Enterprise pricing is custom and requires contacting Subsplash sales. It includes all One features plus custom API integrations, multi-campus apps, and Rock RMS integration.

Source
Overflow: Do we hold the cryptocurrency?

No. Crypto gifts are liquidated and remitted as cash, so the organisation does not carry price risk after settlement.
