To pay early or make a manual payment using the Zip Customer Portal (previously Quadpay), go to https://customer.quadpay.com/en-US/login and log in via verification code, using either your mobile number or account email.
- Once logged in, at the top of the page, select Orders.
- Click View Order next to the order you’d like to make a manual/early payment for.
- Select Pay Now next to the upcoming installment you’d like to pay.
- At the top of this page, select the card you’d like to use, then click Make Payment.
- Shown in the previous screen shot, you may also Add a New Card from this page as well. However, you will still have to repeat steps 1-4 to then use it for your manual payment.
