What APS Bill Pay Is

APS Bill Pay is the online and phone payment system run by Arizona Public Service, the largest electric utility in Arizona. It lets you pay your electric bill without writing a check or visiting a payment location. You can set up one-time payments, schedule recurring payments for the same amount each month, or pay through autopay so the money leaves your account automatically on a date you choose.

APS serves about 1.5 million customers across central and southern Arizona. If your electric bill comes from APS, you can use their Bill Pay system whether you own your home, rent, or manage a business account. The system is free — APS does not charge a fee to pay online or by phone.

You do not need to be an APS customer to pay someone else's bill. If you know the account number, you can make a one-time payment toward any APS account from outside the system, though you will not see payment history or set up recurring payments that way.

Key Takeaways

  • APS Bill Pay is free and available online through your account, by phone at 1-844-277-4357, or through their mobile app.
  • You can pay with a bank account (checking or savings), debit card, or credit card, though credit card payments may carry a processing fee from the payment processor.
  • One-time payments usually post within one to two business days; autopay payments process on the date you select each month.
  • If you set up autopay, you can change or cancel it anytime, and APS will send you a confirmation email when the payment processes.
  • Payments made after 5 p.m. Arizona time on a business day are treated as received the next business day.

How to Set Up a One-Time Payment

Log into your APS account online at aps.com or open the APS mobile app. Click "Pay My Bill" or the payment option on the home screen. Enter the amount you want to pay — you can pay the full balance, the minimum due, or any amount in between.

Select your payment method. If you choose a bank account, you will need your routing number and account number (found at the bottom left of a check). If you use a debit or credit card, enter the card number, expiration date, and CVV. APS does not charge a fee for bank account payments, but some payment processors charge a small fee (usually 2 to 3 percent) if you pay with a credit card.

Choose your payment date. If you select a date that is not a business day, APS will process the payment on the next business day. Review the details, then confirm. You will see a confirmation number on screen and receive a confirmation email. The payment usually posts to your account within one to two business days.

Setting Up Autopay for Monthly Payments

Autopay removes the step of logging in each month. Go to "Pay My Bill," then select "Autopay" or "Recurring Payments." Choose the amount — most customers select "Pay Full Balance" so the entire bill is covered each month, but you can also enter a fixed dollar amount.

Pick the date each month when you want the payment to leave your account. Many customers choose the due date shown on their bill, but you can select any date between the 1st and the 28th. APS will process the payment on that date every month until you cancel.

Confirm your payment method and review the details. You will receive a confirmation email, and APS will send you another email each time a payment processes. If your bill amount changes (which it does seasonally in Arizona), the "Pay Full Balance" option adjusts automatically, but a fixed dollar amount stays the same until you change it.

Payment Methods and Fees

APS accepts payments from a checking account, savings account, debit card, or credit card. Bank account payments are free and are the least expensive option. Debit card payments are also free.

Credit card payments may carry a fee. APS itself does not charge the fee, but the payment processor they use may add 2 to 3 percent to your payment amount. Before you confirm a credit card payment, the system will show you the fee amount and ask you to accept it. You can choose not to pay by credit card if the fee is too high.

If you pay in person at an APS office or payment location, or by mail, those methods are also free. Phone payments made with a representative (not automated) may carry a fee depending on the payment method.

When Payments Post and What Happens If You Miss the Due Date

Payments made before 5 p.m. Arizona time on a business day post the same day or the next business day. Payments made after 5 p.m. or on a weekend or holiday are treated as received the next business day. If your due date falls on a weekend or holiday, APS extends the due date to the next business day at no penalty.

If you do not pay by the due date, APS will add a late fee to your next bill. The amount varies but is typically around 1 to 1.5 percent of your bill. If your account stays unpaid for 30 days past the due date, APS may send a disconnection notice. If it reaches 60 days unpaid, they can disconnect your service.

If you are struggling to pay your bill, contact APS directly. They offer payment plans and hardship programs that may lower your bill or spread payments over time. These are separate from Bill Pay and require a conversation with APS customer service.

Changing or Canceling Autopay

Log into your APS account and go to "Autopay" or "Recurring Payments." You will see your current autopay setup. To change the amount, select "Edit" and enter a new amount. To change the payment date, select the date field and pick a new one. To cancel autopay entirely, select "Cancel Autopay" and confirm.

Changes take effect when ready for future payments. If you cancel autopay, your next scheduled payment will not process, but any payment already scheduled for today or tomorrow will still go through. APS sends a confirmation email when you make changes.

If you cancel autopay and forget to pay manually, your bill will become late. Set a phone reminder or calendar alert if you are switching from autopay to one-time payments.

Troubleshooting Common Issues

If you see "Payment Declined" when you try to pay, the most common causes are a wrong routing number or account number (for bank payments), an expired card, or insufficient funds. Double-check the numbers and try again. If the problem persists, contact your bank to confirm the account is active and has no fraud blocks.

If you paid but do not see the payment on your bill, wait one to two business days. Payments take time to post. If more than two business days have passed, log into your account and look for a confirmation number from when you made the payment. Call APS customer service at 1-844-277-4357 with that number and they can track the payment.

If you need to pay someone else's APS bill and do not have their account login, you can make a one-time payment without logging in. Go to aps.com, select "Pay Without Logging In," and enter the account number you want to pay toward. You will not be able to see payment history or set up recurring payments this way, but the one-time payment will work.

Frequently Asked Questions

Is there a fee to use APS Bill Pay?

No. APS does not charge a fee for paying online, by phone, or through the app. Bank account and debit card payments are free. Credit card payments may have a processing fee of 2 to 3 percent added by the payment processor, and APS will show you that fee before you confirm the payment.

Can I pay my APS bill from my bank's bill pay system?

Yes. Most banks let you set up APS as a payee in their bill pay system and send a check or electronic payment directly. This is free and works well if you already use your bank's bill pay for other bills. The payment may take a few extra days because it goes through your bank first.

What happens if I set up autopay but my payment method expires?

If your card expires or your bank account closes, your autopay payment will fail. APS will send you a notice and may add a late fee. Log into your account and update your payment method right away, or call customer service to fix it before your next payment date.

Can I schedule a payment for a future date that is more than a month away?

One-time payments can be scheduled up to 30 days in the future. If you want to pay further ahead, set up autopay instead, which repeats every month on the date you choose.

What if I overpay my bill?

If you pay more than you owe, the extra amount becomes a credit on your account. APS will explore it to your next bill automatically. If you want a refund instead, contact APS customer service and they can process one, though it may take a few weeks.
