Sezzle

Sezzle is a 'Buy Now, Pay Later' platform that allows consumers to split purchases into interest-free installment payments. It offers solutions for both shoppers and merchants, enabling flexible payment options online and in-store, and aims to increase sales and customer conversions for businesses.

Sezzle is a 'Buy Now, Pay Later' service, which is a form of payment processing. While it doesn't offer a developer API in the same vein as Stripe, it does integrate with various e-commerce platforms. It provides installment payment plans, which can be seen as a form of billing and subscription management for individual purchases. The merchant dashboard offers reporting, and it supports both online and in-store payments (via virtual card, similar to a terminal concept). It also mentions multi-currency support and invoicing for merchants, and a customer portal for managing payments. However, it lacks the broad developer-first API infrastructure, fraud detection, and other advanced financial services that Stripe offers.
