With Affirm, you can offer quick, simple, and transparent financing that allows shoppers to pay over time for their purchases. Founded by Max Levchin, co-founder of PayPal, our mission is to provide products and services that empower people to advance their financial well-being. With Affirm, there are no gimmicks like deferred interest, compounding interest, or late fees, so what your customers see at checkout is exactly what they’ll pay, on a budget-friendly schedule of their choosing. On average, our partners see an AOV increase of 75%. And in third-party A/B tests with a sample of our partners, conversion increased by up to 20%, while revenue per visitor increased by 10% or more.

The Affirm extension modifies your payments page to accept Affirm as a payment type, and also adds Affirm as a payment processor, allowing all authorizations, captures, and refunds to be processed through Magento. Additionally, the Affirm extension provides promotional marketing tools to calculate and display estimated monthly payment amounts based on a product or a shopping cart price. To set up Affirm as a payment method, you’ll need to contact Affirm for API keys and account setup.


Account & Pricing

A separate Affirm account is required to implement financing. Please reach out to us at https://www.affirm.com/business. Although Affirm's Magento extension is free, an Affirm financing partnership may not be. Affirm’s solution does not impact merchants’ PCI compliance. Information affecting a merchant’s PCI compliance is never passed by Affirm to the merchant.
