About Affirm

Affirm is a fintech company that provides point-of-sale “buy now, pay later” financing, letting consumers split purchases into options like interest-free Pay in 4 or longer-term loans with transparent pricing. It emphasizes no hidden fees and shows the total cost upfront so shoppers can choose flexible payment plans with lower payments. Merchants integrate Affirm at checkout via APIs and partnerships to offer financing, improve conversion, and manage underwriting and payouts. Consumers can manage plans and payments through Affirm’s app and online tools.
