What is Affirm?

Whether your customers are planning to take a trip, upgrade some appliances, or just do something kind for someone they care about, they’re all looking for a way to buy the things they love. But the reality is, sometimes these purchases don’t fit comfortably into their monthly budget. This is where we come in: We provide the option for your customers to buy now and pay over time, giving them financial flexibility and the confidence to say yes to that next big purchase.
