Affirm, Shopify Launch Shop Pay Installments in Australia

Amazon Business is Amazon's B2B procurement marketplace, combining business pricing with purchasing controls and analytics for organizations ranging from small firms to large enterprises. Affirm had already offered pay-over-time financing to U.S. retail shoppers on Amazon.com since 2021, later expanding to Canada and Amazon Pay. Extending the relationship into business purchasing is significant because installment credit can help sole proprietors fund equipment and supplies while smoothing cash flow.

Amazon and Affirm announced the expanded partnership on Nov. 2, 2023, making Affirm the first pay-over-time provider available at Amazon Business checkout. The service began rolling out that day to eligible U.S. sole proprietors and was due to reach all eligible sole-proprietor customers by Black Friday on Nov. 24. Approved borrowers could choose customized terms of three to 48 months. Affirm said a $200 purchase at 15% APR would cost $34.81 a month for six months, or $208.84 in total, with no late or hidden fees.

Stripe and Affirm began working together in the United States on May 31, 2022, embedding BNPL into online checkout before expanding the partnership to Canada and Stripe Terminal. Stripe processes more than $1.9 trillion in payments annually. Its move into the consumer credit market overseen by the UK Financial Conduct Authority has implications for merchant conversion rates and consumers’ installment-payment options.

The companies announced on June 2, 2026, that UK Stripe merchants will be able to add Affirm installment plans to online checkout beginning in July. Data from the United States and Canada show that adding Affirm increased revenue from eligible shopping sessions by an average of 13.9% and raised conversion rates by 21.3% for transactions above $250, providing the performance case for the UK expansion.

Affirm and Stripe have worked together since 2021, initially bringing buy now, pay later, or BNPL, to online checkout and Stripe Terminal. As AI agents begin finding products and placing orders for consumers, their ability to recognize secure payment credentials and installment options will be critical to the global BNPL transaction market, which exceeds $300 billion.

Affirm announced on March 3, 2026, that it would support Stripe’s Shared Payment Tokens, or SPT. Once authorized by a user, an AI agent can complete an eligibility check, select a fixed installment plan and make a payment within the platform. Stripe processes the transaction without exposing sensitive credentials. Plans are available with APRs as low as 0%. Merchants using Stripe directly will be the first to gain access, with support for other merchants expected to expand later in the year.
