Sezzle Inc. (SEZL) is a technology-enabled BNPL provider offering interest-free installment payments to consumers, primarily in the US and Canada. While financial ratios demonstrate strong compliance with debt and liquidity thresholds across AAOIFI, MSCI, and S&P standards, the interest income ratio of 3.09% is within limits but historically fluctuated above 5%. Business activities are largely permissible, focusing on deferred payments without riba to end-users, though funding mechanisms warrant monitoring. Overall, the stock is classified as non-compliant due to exclusion from major Shariah indices, reflecting sector-specific scrutiny in credit services. Investors should consider purification of 3.09% for any impure income and consult scholars on BNPL models.
