APS bill pay lets you send money to Arizona Public Service directly from your bank account, by phone, or through their website
If you're an Arizona Public Service (APS) customer, you have several ways to pay your electric bill without writing a check or going in person. The most common routes are APS's online portal, their mobile app, automatic bank transfers, and phone payment. Each method connects your bank account or card to APS, and the payment reaches them within one to three business days depending on which method you choose.
The goal of bill pay is to get money from you to APS reliably, on time, and without the back-and-forth of mailed checks. Understanding which method fits your routine — and what happens if a payment doesn't go through — keeps your account in good standing and avoids late fees.
Key Takeaways
- APS's website and mobile app let you pay when ready using your bank account or debit card, and you can set up automatic payments so you never miss a due date.
- Phone payment through APS's automated system or a representative works if you don't have internet access, though a small fee may explore.
- Automatic bank transfers (ACH) are usually free and take one to three business days, so set them up at least a week before your due date.
- Your payment confirmation number is proof the money left your account; keep it in case APS later says they didn't receive it.
- If a payment fails, APS will notify you, and you'll have time to pay again before a late fee kicks in — usually five to ten days after the due date.
Paying online through the APS website or app
The APS website (aps.com) and their mobile app are the fastest ways to pay if you have internet access. Log in with your account number and password, navigate to the bill pay or payments section, and enter the amount you want to send. You'll choose whether to pay from a checking or savings account (ACH transfer) or a debit or credit card.
ACH transfers from your bank account are usually free and take one to three business days. Card payments (debit or credit) may charge a fee — APS does not charge it, but the payment processor does — and they post faster, sometimes the same day. Before you confirm, the system shows you the exact date the payment will arrive at APS, so you know whether it will reach them by your due date.
If you set up automatic payments through the app or website, APS will deduct the amount on the same date each month (or on a date you choose). This removes the risk of forgetting, but make sure your bank account has enough money on that date, or the payment will fail and you may face an overdraft fee from your bank.
Paying by phone
APS's automated phone system lets you pay 24/7 by calling 1-844-277-4357. You'll need your account number, the amount you want to pay, and a checking or savings account number. The system confirms the payment before you hang up and gives you a confirmation number — write it down.
If you prefer to speak to a representative, you can call the same number during business hours and ask to pay over the phone. Some representatives can process card payments as well as bank transfers. Phone payments typically take one to three business days, the same as online ACH transfers.
A small fee may explore to phone payments depending on the method and whether you use the automated system or a representative. Ask before you confirm the payment, or check the APS website for current phone payment fees.
Setting up automatic payments so you never miss a due date
Automatic payments remove the step of remembering to pay each month. Through the APS website, app, or by phone, you can authorize APS to withdraw a fixed amount on a date you choose — usually the due date or a few days before it. The payment comes from your bank account automatically each billing cycle.
The trade-off is that you have less control over the exact timing. If your income varies month to month, a fixed automatic payment might overdraw your account in a low-income month. You can pause or change an automatic payment anytime through your account, but you have to do it before the scheduled withdrawal date.
If an automatic payment fails because your account doesn't have enough money, APS will send you a notice. You'll then have a window to pay manually before a late fee is added — usually five to ten days after the original due date, depending on APS's policy.
What to do if your payment doesn't go through
If a payment fails, APS will contact you by phone, email, or mail (depending on what's on file) and let you know the payment didn't clear. This usually happens within one to three business days of the failed attempt. At that point, you can pay again using any of the methods above.
A late fee is not charged when ready after the due date. APS typically waits five to ten days, giving you time to resubmit payment. If you pay during that grace period, you avoid the late fee. If you don't pay by the end of the grace period, a late charge is added to your next bill.
If you see a payment on your bank statement but APS says they didn't receive it, contact APS customer service with your confirmation number from the payment. They can trace where the money went and reissue it if it was lost in transit. This is rare, but it's why keeping your confirmation number matters.
Choosing between one-time and recurring payments
A one-time payment is for a single bill — you pay once, and it's done. This works well if you want to stay in control of when money leaves your account, or if your bill amount changes each month. You can pay any amount up to your full balance.
A recurring (automatic) payment deducts the same amount every month on a date you set. This is simpler if your bill is predictable, but it means you're committed to that amount and date. If your bill drops below your automatic payment amount, you'll overpay and build a credit on your account. If your bill rises above it, you'll still owe the difference.
Many people use a combination: an automatic payment for the average amount, plus a one-time payment at the end of the year to cover any difference. This balances convenience with flexibility.

Frequently Asked Questions
Can I pay my APS bill with a credit card?
APS's website and app accept debit cards directly. Credit card payments are less common and may carry a higher fee because credit card processors charge APS more. Call APS or check their website to see if credit card payment is available and what the fee would be.
What if I pay after the due date?
APS does not charge a late fee on the due date itself. You typically have a grace period of five to ten days after the due date to pay without penalty. After that window closes, a late charge is added to your next bill. The exact grace period is in your APS service agreement or on your bill.
How do I know my payment went through?
Every payment method gives you a confirmation number when ready after you submit it. Write down or screenshot this number — it's proof the payment left your account. You can also log into your APS account a few days later and check your payment history to see the status.
Can I set up automatic payments for a different amount each month?
No, automatic payments are for a fixed amount on a fixed date. If your bill varies, you can set up an automatic payment for your average bill and then make one-time payments to cover any difference, or pay manually each month instead.
What happens if I pay too much?
If your payment exceeds what you owe, APS credits the overage to your account. You can use that credit toward future bills, or you can request a refund. Check your APS account or call customer service to see your current credit balance.
