FAQ
Is Klarna safer than Affirm for a global rollout?
Klarna leads where UK and EU procurement teams read CNBC and Fortune on incoming rules. Pick Affirm when US large-ticket financing matters more.
When does Afterpay beat PayPal?
Choose Afterpay when Cash App or Square distribution already fuels acquisition, per Block. Choose PayPal when checkout already depends on the PayPal wallet.
Does Sezzle make sense next to Klarna?
Yes for Shopify-heavy SMBs: Shopify still lists Sezzle beside majors, and G2 shows reach gaps.
Will BNPL fees keep rising?
Shopify’s payment guide notes BNPL merchant fees often exceed cards because lenders subsidize shopper interest. Re-model whenever promos change.
