It allows consumers to make purchases and pay over time through installment plans, often without hidden fees or deferred interest. Affirm partners with merchants to integrate its payment options into online and in-store shopping experiences, using user-friendly plugins and APIs. The company earns revenue from interest and fees on loans to consumers, as well as from merchants who pay to offer Affirm's financing. Additionally, Affirm offers a merchant dashboard for transaction processing and promotional tools to help businesses market these financing options. The goal of Affirm is to empower consumers with flexible payment solutions while providing value to merchants.

Reporting Bnpl Performance To Bureaus May Broaden Pool Of Credit-Worthy Consumers

PYMNTS Intelligence has detailed that consumers opt for buy now, pay later (BNPL) plans because they’re convenient and accessible. More than half of the individuals that we’ve surveyed have said that they’d used installment options through the past year. And 76% of those consumers who used BNPL plans voiced high levels of satisfaction with those plans. The plans are widely available, and our data notes that paying over time holds appeal for users across all income levels, even high earners, where a third of consumers making more than $100,000 annually had used BNPL. For the consumers with low credit scores or even no credit scores, the movement toward including BNPL loans in credit and underwriting decisioning — as BNPL performance is harnessed by the credit reporting agencies — is gaining momentum
