Overflow

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.

This is a specialist tool, and the pricing reflects that. Overflow's stock-processing plan runs a flat $2,500 per year, 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.

Because its scope is so narrow, Overflow should not be scored as a full giving platform, on that basis it would look thin. Judged as the category's leading non-cash giving specialist, it is strong: 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.
