The Buy Now Pay Later (BNPL) model allows customers to purchase products immediately and pay for them over time. It’s a popular alternative to bank credit cards and loans, especially among younger generations who are cautious about debt but still want the instant gratification of e-commerce. From a business perspective, BNPL offers a way to enhance the customer experience, increase sales conversion rates, and attract a broader customer base. Installment payment software is often used to provide BNPL options to customers, without adding immediate financial burden. The global user base of BNPL is currently around 360 million, with Klarna being the leading service provider with 147 million active users. Clothing is the most frequently purchased item through BNPL services. The market is projected to reach $3.27 trillion by 2030 and the number of BNPL users could double by 2027, reaching 900 million. The largest group of users falls within the 18 to 34 age bracket, constituting 41.6% of all BNPL users. Clarity of fees is the most critical factor for BNPL users, followed by the ability to monitor spending, convenience, and acceptance by a large number of merchants. Clothing accounts for the majority of BNPL purchases, followed by entertainment and reading materials. The BNPL industry is expected to grow significantly, with projections estimating a value of over $100 billion by 2024 and over $150 billion globally.
