APS bill pay lets you settle your account through their website, mobile app, or by phone without visiting a payment location
Arizona Public Service (APS) offers several ways to pay your bill online. The most direct route is logging into your account at aps.com, where you can make a one-time payment or set up automatic payments. You can also use the APS mobile app (available on iOS and Android), call their payment line at 1-844-277-4357, or authorize a payment through your bill itself. All methods connect to the same account system, so your payment posts the same day regardless of which route you choose.
The key difference between methods is timing and control. Online and app payments let you choose your exact payment date and amount. Phone payments work the same way but require speaking to someone. Automatic payments remove the step entirely — APS withdraws your bill amount on a date you set, usually around your due date. Each method is free; APS does not charge a fee for any standard payment option.
Key Takeaways
- You can pay through aps.com, the APS mobile app, or by phone at 1-844-277-4357, and all methods are free.
- One-time payments post the same day if submitted before 5 p.m. Arizona time on a business day; weekend or holiday payments post the next business day.
- Automatic payments remove the need to remember your due date, but you must set them up in advance through your online account.
- If you pay late, APS adds a late fee to your next bill; paying on or before the due date shown on your bill avoids this charge.
- Payment history appears in your online account within 24 hours, so you can confirm the transaction without waiting for a paper receipt.
Setting up a one-time payment on aps.com
Log into your APS account using your username and password. If you do not have an online account yet, you will need to create one first — you can do this on the APS homepage by selecting "Create Account" and providing your service address, account number (found on your bill), and email address.
Once logged in, look for the "Pay My Bill" or "Make a Payment" button, usually on the account dashboard. Enter the amount you want to pay (you can pay the full bill, a partial amount, or more than the bill if you want a credit). Select your payment date — this is the date APS will process the payment, not the date the money leaves your bank. Choose your payment method: bank account (ACH transfer) or debit/credit card. Bank account payments are free; card payments may carry a small fee depending on the card processor APS uses.
Review the details, confirm the payment, and you will see a confirmation number on screen. Write this down or take a screenshot. The payment posts to your account the same business day if submitted before 5 p.m. Arizona time; if you submit after 5 p.m. or on a weekend or holiday, it posts the next business day.
Using automatic payments to avoid missed due dates
Automatic payments (sometimes called "autopay") withdraw money from your bank account on a date you choose, usually around your bill due date. This removes the step of remembering to pay each month. To set this up, log into your APS account, find the "Automatic Payments" or "Autopay" section, and select "Enroll." You will provide your bank account number and routing number, then choose the date each month when APS should withdraw the payment.
APS will deduct the full amount due on your bill each month. If your bill varies (which it does for most customers, especially seasonally), the withdrawal amount changes each month to match. You can pause, change the date, or cancel autopay at any time through your online account — there is no penalty for stopping it.
One thing to watch: if you enroll in autopay, you still need to check your bill each month to make sure the amount is correct. If APS makes an error and withdraws too much, you can dispute it through your bank or contact APS directly to request a reversal. Autopay is convenient, but it does not replace reading your bill.
Paying by phone or through the APS mobile app
If you prefer not to use the website, you can call APS at 1-844-277-4357 to make a payment. Have your account number (on your bill) and your bank account or card information ready. A representative will walk you through the payment and give you a confirmation number. Phone payments process the same way as online payments — same-day posting if before 5 p.m. Arizona time on a business day.
The APS mobile app offers the same features as the website: one-time payments, automatic payment setup, and bill history. Download the app from your phone's app store, log in with your APS account credentials, and navigate to the payment section. The app is useful if you want to pay on the go or check your account balance without opening a web browser.
What happens if you miss your due date
Your APS bill shows a due date, usually 20 to 25 days after the bill is issued. If you do not pay by that date, APS adds a late fee to your next bill. The fee amount varies but is typically a percentage of your bill or a flat amount — check your bill or contact APS for the exact fee in your area.
Paying late does not immediately disconnect your service. However, if you fall significantly behind (usually 60 days or more), APS may send a disconnection notice. If you receive a notice, contact APS right away to discuss a payment plan or other options. Many customers can arrange to pay arrears over several months rather than in one lump sum.
If you are struggling to pay your bill, APS offers programs like budget billing (which spreads costs evenly across 12 months) and bill assistance for low-income households. These are separate from bill pay itself, but they can make your monthly payment more manageable.
Confirming your payment and checking your account history
After you submit a payment, you will see a confirmation number on screen. Save this number — it proves you made the payment if there is ever a dispute. The confirmation also shows the payment date and amount.
Your payment appears in your online account history within 24 hours. Log back into aps.com and look for a "Payment History" or "Account History" section to see all past payments, dates, and amounts. This is useful for tracking what you have paid and when, especially if you make multiple payments in a month or are catching up on arrears.
If a payment does not appear after 24 hours, or if you see an error, contact APS customer service. Have your confirmation number ready. APS can tell you whether the payment is still processing or if there was a problem.
Avoiding common payment mistakes
The most common mistake is confusing the payment date with the posting date. If you submit a payment on Friday at 6 p.m., it will not post until Monday. If you are trying to avoid a late fee, make sure you submit the payment before 5 p.m. Arizona time on or before your due date, not just on the due date itself.
Another mistake is paying the wrong amount. Always check your bill for the exact amount due. If you have a balance from a previous month, the amount due includes that balance plus the current month's charges. Paying only the current month's charges leaves the old balance unpaid, and APS will add a late fee.
A third mistake is setting up autopay and then forgetting about it. If your bill drops significantly (for example, if you move or your usage changes), autopay will still withdraw the full amount due, which might be less than you expected. Check your bill each month to make sure the autopay amount is reasonable.
Finally, do not assume a payment is complete just because you submitted it. Always wait for the confirmation number and check your account history the next day to confirm the payment posted. This takes two minutes and prevents disputes later.
Frequently Asked Questions
Can I pay my APS bill with a credit card?
Yes, but APS may charge a processing fee if you use a credit card. Bank account (ACH) payments are free. The fee amount varies by processor. When you enter your payment information, APS will show you whether a fee applies before you confirm.
What if I want to pay more than my bill amount?
You can pay any amount, including more than what is due. The extra amount becomes a credit on your account and applies to future bills. You can also request a refund of a credit balance, though this may take several weeks to process.
Is it safe to pay through the APS website?
APS uses standard encryption to protect your account information. Never share your password, and always log in directly through aps.com rather than clicking a link in an email. If you receive an email asking you to verify your account or payment information, contact APS directly before responding — it may be a phishing attempt.
Can I schedule a payment for a future date?
Yes. When you make a one-time payment, you choose the date APS will process it. You can schedule a payment up to several days in advance. This is useful if you want to ensure the payment posts by your due date but do not have the money until a specific date.
What if my payment fails?
If your bank declines the payment (for example, due to insufficient funds), APS will notify you and the payment will not post. You will need to contact APS or try again with a different payment method. A failed payment does not count as a late payment, but your bill remains unpaid, so you should resubmit as soon as possible.
