Keep more of your donations
Keep 100% of every
one-time donation.
Donors can 'Boost' their gift to cover processing fees. That means 100% of every one-time donation goes straight to you. Even if donors don't cover your fees — Harness will. With Boost turned on, every donor dollar reaches your mission.
Why Boost matters?
Most donation forms lose supporters to slow load times, confusing layouts, or too many required fields. When checkout is clunky, donors abandon the process—and nonprofits lose revenue they never even see.
Harness Donation Checkout fixes that.

“When I tell other nonprofit organizations in my community about Harness…some of them say ‘It's too expensive to get that.’ And I say it’s too expensive to NOT have it.”
