Stripe Link in Checkout

What we tested

We ran a test to evaluate the impact of enabling Stripe Link on the payment screen of the mobile Checkout Modal, as well as the desktop and mobile Campaign Pages.

Stripe Link is Stripe’s one-click checkout experience. Once a donor saves their payment information (email, phone number, card, billing address) in the Stripe ecosystem, they can reuse it across any site with Link enabled, authenticating via a quick email or SMS code.

We wanted to know: would enabling Stripe Link lead to higher conversion and faster payments, without negatively impacting average gift size or donor behavior?

Hypothesis

After adding Stripe Link to Checkout, we expected to see:

• ≥10% of donors opting to save their card with Link
• ≥20% of U.S. donors completing payment using Link
• No drop in average gift size among Link users

Test setup

Key results

Checkout Modal (mobile)

• Share of total revenue: 0.98%
• Actual usage rate: 1.13%

Campaign Pages

• Share of total revenue: 1.15%
• Actual usage rate: 1.14%

Conclusion

While Stripe Link promises a faster checkout experience, real-world adoption during the test was lower than expected — just over 1% of donors chose it, and the overall impact on revenue was minimal.

Given the limited usage and no significant performance lift, we won’t be rolling this out just yet. We’ll continue to monitor and explore other optimizations that deliver measurable value across devices and donor types.

What this means for you

We’re constantly testing new payment methods and improvements to Checkout to ensure only the most effective ones reach your donors.

That means your Checkout experience is continuously optimized with what actually works, helping your nonprofit raise more with confidence.
