Donation checkout for nonprofits
A fast, high-converting giving experience
Harness gives you a modern, mobile-first checkout built to convert. Refined through continuous testing, our donation flow removes friction and encourages recurring gifts.
Why donation checkout 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.
