AfterPay is an E-Commerce Business. Apple Pay is a payment method.

As another user has said. Afterpay is basically like Amazon or Kogan in many ways.

You go on Afterpay to shop for products using a BNPL method.

No store is going to have Apple Pay Later signs like Afterpay.

Apple Pay Later is a payment method at checkout. It also requires you to have a credit card, which is completely different to Afterpay. Apple is not perfect. Apple+ and AppleTV are basically flops. Apple Pay has barely any market share in the consumer industry. Afterpay is already partnered with Google Pay.
