Our verdict on Affirm
Affirm is a buy now, pay later platform for merchants and consumers. It supports Pay in 4 interest-free payments every two weeks, as well as installment financing with terms from 6 weeks to 36 months. Merchants can offer payment options through online checkout, in-store experiences, telesales, virtual cards, and direct API integrations. Consumers manage repayment and purchasing power through Affirm’s app. It is suited to merchants that want flexible financing across multiple sales channels rather than a checkout-only option.
Merchant pricing is customized. Affirm documents merchant discount rates and transaction fees, while the published pricing details describe no recurring integration, annual, or monthly fees. The platform also has a free plan. Settlement timing depends on the integration and payment method: ACH is documented as within 1–3 business days, while another official page describes a 24-hour rolling basis. Merchants should therefore confirm commercial terms and settlement arrangements for their specific setup before choosing the service.
Platform fit is a central strength. Affirm supports web, iOS, Android, a Chrome extension, and API access, with integrations for Adobe Commerce, BigCommerce, Salesforce Commerce Cloud, SAP Commerce, Shopify, Wix, WooCommerce, and other listed ecommerce platforms. Its Merchant Portal covers charges, refunds, and transaction management, while promotional payment messaging helps merchants present financing at checkout. Merchants serving shoppers in the United States, Canada, or United Kingdom and needing both short and extended repayment options should consider Affirm. Businesses seeking simple, publicly stated pricing or coverage outside those regions may prefer another provider.
