Sezzle

Sezzle is a digital payment platform that helps you increase sales by offering your customers flexible financing at checkout. Instead of paying the full amount immediately, your shoppers can split their purchases into four interest-free installments over six weeks. This approach reduces cart abandonment and increases average order value by making larger purchases more manageable for your budget-conscious customers.

You receive the full payment for every transaction immediately, while Sezzle handles the credit risk and collection process. The platform integrates directly with your existing e-commerce store, providing a smooth checkout experience that builds trust and loyalty. Whether you run a small boutique or a large retail operation, you can provide a modern payment alternative that appeals to younger generations who prefer avoiding traditional credit card debt.
