Overview

Affirm

Affirm helps you increase sales and reach new customers by offering flexible payment options at checkout. Instead of paying the full price upfront, your customers can choose a payment plan that fits their budget, ranging from four interest-free payments to longer-term monthly installments. This flexibility helps you reduce cart abandonment and increase average order value by making larger purchases more accessible to your audience.

You can integrate the platform directly into your existing e-commerce stack to provide real-time credit decisions for your shoppers. Because Affirm pays you upfront and handles the risk of collections and fraud, you can focus on growing your business while providing a transparent, fee-free experience for your customers. It is a straightforward way to build trust and loyalty with a modern mobile-first audience.

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.
