A fast food chain whose mobile app handles ordering, checkout and loyalty rewards.
Chick-fil-A's app payment screen led customers to think only the loyalty card was accepted, which hurt cart conversions. An A/B test of new layouts and CTAs lifted credit card payments 6% and cut related complaints to 0. Lesson: show every accepted payment method clearly at checkout, and use customer confusion complaints as a source of test ideas.
Credit card payments up 6%, complaints cut to 0
From Chick-fil-A payment screen A/B test
Chick-fil-A fixed a payment screen that implied only the loyalty card worked. The app's payment layout made customers think the loyalty card was the only accepted method, which lowered cart conversions. New layouts and CTAs made the other options clear, lifting credit card payments 6% and cutting customer complaints about the confusion to 0.
The team did not just reword a button. They tested layouts and CTAs together, changing both how the options were arranged and how the action was labeled. Complaints served as the source of the hypothesis and as a second success metric. The lesson: check whether any checkout step, such as leading with a loyalty card, reads as a requirement rather than an option.
