Roundup fundraising for nonprofits

Turn everyday generosity into recurring impact

Roundup fundraising lets supporters donate spare change automatically by rounding up everyday purchases. Harness makes it easy to launch, manage, and grow roundup giving as a sustainable source of recurring donations, without adding friction for donors or extra work for your team.

Why roundup fundraising matters?

Most supporters want to give more, but not all of them are ready for large or frequent donations. Traditional campaigns often miss this middle ground.
Roundup fundraising fills the gap. It transforms small, everyday transactions into consistent support that adds up over time. Instead of asking donors to make repeated decisions, you give them a simple way to support your mission passively and continuously.
For nonprofits, that means:
Steadier revenue
Stronger donor habits
More predictable giving without more campaigns.

“Harness has let me do more of the fundraising with less team. I've been able to do a similar amount of outreach and data tracking despite missing two full time staff.”
