The tie-up lets any of the 676,000 businesses already on Airwallex’s rails—from Singapore to São Paulo—present Affirm’s transparent installment plans to eligible American shoppers without a single line of new code. Merchants simply flip a switch in the Airwallex dashboard and instantly offer four interest-free payments or 24-month terms, complete with upfront pricing and no late fees. Jason Gottlieb, Airwallex’s vice-president for financial and strategic partnerships, frames the move as a conversion lever rather than a gimmick. “Merchants choose Airwallex to maximize local payment options for shoppers around the world, otherwise they’re leaving conversion on the table,” he said. Internal data from Affirm shows that merchants who add BNPL can lift average order values by 20-30 % and cut cart abandonment by as much as 40 %.
