When your payment is sent using electronic payments, ACH, funds are withdrawn from your account closer to the delivery date. Here's how the process works. Click pay next to the biller you'd like to pay. Enter the amount you want to pay. Choose your estimated delivery date. If you're paying with electronic payments, ACH, the money will be withdrawn from your account one business day before the estimated delivery date. Click pay to submit your payment. On the confirmation screen, you'll see both the estimated delivery date and the withdrawal date. Please make sure enough money is in your account on the withdrawal date so your payment can be processed successfully.
