Afterpay does not charge interest as long as you pay on time.If you do miss a payment, you will incur a late fee, and you won’t be able to buy or book anything else with Afterpay until you settle your account. Afterpay will charge you a capped late fee that starts at $10 but never goes higher than 25% of the purchase price or $68 (whichever is less). On a $40 purchase, for example, that means no more than $10 in late fees. But no interest, ever.

" Afterpay does not affect your credit score or credit rating, full stop. Your credit score can be impacted when somebody does a credit check on you or if you are reported as paying debts late; at Afterpay, we never do credit checks or report late payments. We don’t believe in preventing people from accessing Afterpay because they may have had an old debt from a long time ago. And we don’t believe that missing a payment with Afterpay should result in a bad credit history - especially when the average purchase is only around $150 (which may surprise you). Our main aim is always to help you spend responsibly, and we take a lot of steps to help ensure this, including pausing your account when you miss a payment." -https://www.afterpay.com/en-AU/afterpay-finance-myths-and-questions

Setting up an Afterpay account is a simple process, and anyone over 18 can do it. To make it quick and easy for you, we verify your identity electronically (rather than you having to do time-consuming paperwork). Then, when you want to make a purchase with any of our partner retailers, just choose Afterpay as your chosen payment method at the checkout. It’s important to know that we do apply an approval process for individual purchases. This is because we’re completely committed to ensuring responsible spending. Our approval process takes a number of factors into account, including whether there are sufficient funds in your account (particularly for new customers), and how much you will have to repay on the purchase. We carry out this process on every order you make with Afterpay, not just the first one. You should know that we don’t approve 100% of orders as we’re committed to ensuring responsible spending for Afterpay customers.
