Overflow
A modern giving platform that lets donors give stock, crypto, donor-advised funds, and ACH, used by many high-profile churches.
Our verdict
Overflow does one thing that most giving platforms barely touch: it makes donating appreciated stock, cryptocurrency, and donor-advised fund grants nearly as simple as a card gift. For churches and nonprofits, that matters because non-cash assets are where much of a supporter's real wealth sits, and a smooth flow for gifting stock or Bitcoin can unlock donations that would never have happened through the offering plate. The donor experience for these complex gifts is genuinely impressive.
Overflow's stock-processing plan runs a flat $500 per year on Foundation (Growth and Enterprise custom), which is easy to justify for an organization that expects to receive sizable appreciated-asset gifts but hard to swallow for a small church whose giving is almost entirely cash and card. It is designed to sit alongside a primary giving platform, handling the non-cash lane while your everyday tithes flow through something like Tithe.ly or Givelify.
It still leads on stock, crypto, and DAF flows. automated acknowledgement letters, giving statements, and concierge support round out a focused product. Recommended as a complement for organizations with donors holding appreciated assets, not as a standalone solution.

Best for
Churches and nonprofits with donors who hold appreciated stock, crypto, or donor-advised funds and want a smooth way to unlock those large non-cash gifts.

FAQ
What does Overflow do?
Overflow specializes in non-cash giving, making it simple for donors to give appreciated stock, cryptocurrency, and donor-advised fund grants to your organization.
How much does Overflow cost?
Its stock-processing plan is a flat $500 per year on Foundation (Growth and Enterprise custom), which suits organizations expecting sizable appreciated-asset gifts more than small cash-based churches.
Is Overflow a full giving platform?
No. It is a specialist for non-cash gifts and is designed to sit alongside a primary platform that handles everyday card and ACH tithes.
Why accept stock or crypto gifts?
Appreciated assets carry tax advantages for donors and represent wealth that rarely flows through the offering plate, so accepting them can unlock much larger gifts.
Does Overflow handle tax paperwork?
Yes. It automates acknowledgement letters and giving statements, reducing the administrative burden that non-cash gifts typically create.
