PSO online payment works through AEP's website or mobile app, and takes about five minutes once you have your account number
Public Service Company of Oklahoma (PSO), which is part of American Electric Power, lets you pay your bill online without calling or visiting an office. You can pay through their website at pso.com, use their mobile app, or set up automatic payments so the bill comes out of your account each month. The payment posts the same day if you pay before 5 p.m. Central Time on a business day.
You will need your PSO account number (found on your bill) and a bank account or debit card to get your free guide. If you do not have your bill handy, you can look up your account using your service address and phone number instead. Paying online costs nothing — there is no fee from PSO, though your bank may charge a fee if you use a credit card.
Key Takeaways
- You can pay online at pso.com, through the PSO mobile app, or by setting up automatic payments from your bank account.
- One-time online payments post the same day if submitted before 5 p.m. Central Time on a business day, with no fee from PSO.
- You need your account number or service address to log in, plus a bank account or debit card to complete the payment.
- Automatic payments let you choose a due date each month and avoid late fees, though you can cancel anytime.
Steps to pay a one-time bill online
Go to pso.com and select "Pay My Bill" or "Make a Payment" from the homepage. You will be asked to log in or create an account. If you already have a PSO online account, enter your username and password. If not, you can create one using your account number and service address, or pay as a guest without logging in.
Once logged in, your bill amount and due date will appear on screen. Review the amount to make sure it matches your paper bill or email statement. Enter your payment method — either a bank account (routing and account number) or a debit card (card number, expiration date, and CVV). Choose your payment date. If you select today and it is before 5 p.m. Central Time on a business day, the payment will post the same day. If you select a future date, the payment will process on that date.
Click "Confirm" or "Submit Payment" and you will see a confirmation number on screen. Write down this number or take a screenshot — you will need it if you have questions about the payment later. PSO will also send you a confirmation email within a few minutes.
Setting up automatic payments to avoid late fees
Automatic payments mean your bill comes out of your bank account on the same date each month, so you never have to remember to pay. Go to pso.com, log into your account, and look for "Autopay," "Automatic Payments," or "Recurring Payments" in the account settings menu. Select the bank account or debit card you want to use, then choose the date each month when you want the payment to come out.
Most people choose the due date shown on their bill, but you can pick any date that works for your budget. Once you set it up, the payment will happen automatically every month until you cancel. You can cancel anytime by logging back into your account and turning off autopay, or by calling PSO customer service at 1-800-272-9368.
Automatic payments are free and remove the risk of late fees. If your bill amount changes month to month (which is normal for electric bills), PSO will charge whatever the current bill is on your chosen date.
What to do if you cannot pay the full amount
If you cannot afford the full bill, do not ignore it — contact PSO before the due date. Call 1-800-272-9368 and ask about a payment arrangement, which lets you split the bill into smaller payments over time. PSO can usually set up an arrangement over the phone in a few minutes, and you will not face a late fee or service disconnection while the arrangement is in place.
If you are struggling with energy costs, PSO also runs the Percentage of Income Payment Plan (PIPP), which caps your monthly bill at a percentage of your household income. You can ask about PIPP when you call about a payment arrangement, or visit pso.com and search for "PIPP" to learn more about income limits and how to enroll.
Troubleshooting common online payment problems
If your payment is rejected, the most common reason is a mismatch between the name on your bank account and the name on your PSO account. Make sure the name you enter matches exactly — including middle initials and spelling. If the name does not match, you will need to update your PSO account information first, or call customer service to do it for you.
If you see an error message about an invalid routing number, double-check the nine-digit routing number from the bottom left corner of your checks. If you are using a debit card, make sure the expiration date has not passed and that you entered the CVV (the three-digit code on the back) correctly. If the problem persists, try paying through the PSO mobile app instead, or call 1-800-272-9368 to pay over the phone.
If you paid online but do not see the payment reflected in your account within 24 hours, check your confirmation email for the confirmation number and call PSO with that number. Do not pay again — the payment may still be processing. PSO customer service can tell you the exact status and when it will post.
Using the PSO mobile app to pay on the go
The PSO mobile app works the same way as the website but is faster if you are paying from your phone. Download the app from the Apple App Store or Google Play Store, log in with your PSO account, and tap "Pay Bill" or "Make a Payment." The rest of the steps are identical to paying on the website.
The app also shows your current bill, usage history, and estimated bill for the month, which can help you spot unusual spikes in your electric use. You can set up automatic payments through the app as well, and you will get push notifications reminding you when a payment is due.
Frequently Asked Questions
Is there a fee to pay my PSO bill online?
No. PSO does not charge a fee for online payments made from a bank account or debit card. Your bank may charge a fee if you use a credit card, so check with your bank first if you plan to pay with a credit card.
Can I pay my bill with a credit card online?
PSO does not accept credit cards directly through their website or app. You can only pay with a bank account or debit card. If you want to use a credit card, you would need to call customer service at 1-800-272-9368 and ask if they can process it over the phone, though this may involve a fee.
How long does it take for an online payment to show up on my account?
If you pay before 5 p.m. Central Time on a business day, the payment posts the same day. If you pay after 5 p.m. or on a weekend or holiday, it will post the next business day. You will see a confirmation number immediately after you submit the payment.
What happens if I set up autopay and then move to a new address?
Your autopay will continue to work as long as you update your service address in your PSO account. Log into pso.com, go to account settings, and update your address. Autopay will keep running on your chosen date with the new address.
Can I schedule a payment for a specific future date?
Yes. When you make a one-time payment online, you can choose any date in the future (up to a certain limit, usually 30 days ahead). Select that date before you confirm the payment, and PSO will process it on that day.
