Thank you for your post. In PayPal Pay in 3, your first payment will be charged at the time you make the purchase. After that, your 2nd and 3rd payments will be charged in the two subsequent months, on the same day of each month. For example, if you make a purchase on 5th May, your 2nd and 3rd payments will be due on 5th June and 5th July. We’ll send you a reminder by email or SMS 10 days before your payment is due detailing the amount of your payment, the payment due date and the funding instrument the payment will be taken from. You can see your payment schedule or make unscheduled payments at any time by logging into your PayPal account. You can refer to this link to know more about PayPal Pay in 3.
