Ecommerce AfterPay / ZipMoney

I run an E-commerce website and I saw some people on a Facebook group talking about some of our competitors offering AfterPay (which we don't).

I want to try AfterPay or ZipMoney, as I'm assuming some % of customers can't afford to purchase, but would consider doing so if we had AfterPay/ZipMoney.

Between the two, which is better for E-commerce websites? I'm imagine the best option is the one that the most customers recognize or have already registered with. I was about to sign up with AfterPay since the brand is clearer - AfterPay = "Pay After".

Which has the highest market share?
Which is best for sellers?


I bought shares in ZipMoney because I was simply following director purchases, so I barely know the stats behind the 2 companies.
