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.

Answered from the vendors’ own pages

Overflow: What does Overflow cost?

Foundation is 50 USD a month. Cards start at 2.75 percent plus 0.30, ACH at 0.50 percent plus 0.20, stock and DAF at 1 to 3 percent, and crypto adds 3 percent.

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.

Overflow: Does Overflow replace our church management system?

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

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.
