What PSO Bill Pay Is and How to Use It

PSO Bill Pay is the online and phone payment system run by Public Service Company of Oklahoma, the utility that serves most of central and western Oklahoma. You can pay your electric or natural gas bill through their website, mobile app, or by calling their automated phone line. Payments process the same day if you submit them before 5 p.m. Central Time on a business day, or the next business day if you pay after hours or on a weekend.

PSO does not charge a fee to pay online or by phone through their own system. If you use a third-party payment processor — a service that is not PSO's official platform — that processor may charge you a fee, but PSO's direct channels are free. You can set up a one-time payment or enroll in automatic monthly payments that deduct from your bank account on a date you choose.

Key Takeaways

  • PSO's online and phone payment systems are free and process same-day if submitted before 5 p.m. Central Time on a business day.
  • You can pay through the PSO website, their mobile app, or by calling 1-800-272-9368 to reach their automated payment line.
  • Automatic monthly payments require you to provide your bank account number and routing number, and you can change or cancel them anytime.
  • If you pay by mail, allow 7 to 10 business days for the check to arrive and post to your account.
  • Payments made through third-party bill pay services (like your bank's bill pay feature) may take longer and may incur fees from that service.

Paying Online Through the PSO Website or App

Go to psoklahoma.com and log into your account using your username and password. If you do not have an online account, you can create one by entering your account number (found on your bill) and your service address. Once logged in, select "Pay My Bill" or "Make a Payment" — the exact wording varies slightly depending on whether you are on the website or mobile app.

Enter the amount you want to pay. You can pay your full balance, a partial amount, or more than you owe (the overpayment becomes a credit on your next bill). Choose your payment method: bank account (checking or savings), debit card, or credit card. If you use a credit card, PSO charges a 2.5% convenience fee on top of your payment amount. Bank account and debit card payments have no fee.

Review the payment details, including the date it will process, then confirm. You will receive a confirmation number when ready. PSO will send you an email receipt as well. The payment posts to your account the same day if submitted before 5 p.m. Central Time on a business day; otherwise it posts the next business day.

Paying by Phone

Call PSO's automated payment line at 1-800-272-9368. You will need your account number (on your bill) and your bank account information or debit card number. The system will ask you to confirm the amount and the date you want the payment to process. You will receive a confirmation number at the end of the call.

This line operates 24 hours a day, 7 days a week. Payments submitted before 5 p.m. Central Time on a business day process the same day; all other payments process the next business day. If you prefer to speak with a person, you can call PSO's customer service line at 1-800-272-9368 during business hours (Monday through Friday, 7 a.m. to 6 p.m. Central Time) and ask to make a payment over the phone with an agent.

Setting Up Automatic Monthly Payments

Automatic payments deduct your bill amount from your bank account on a date you choose each month, usually between the 1st and the 28th. To enroll, log into your PSO account online, go to "Billing & Payment," and select "Enroll in AutoPay" or "Set Up Automatic Payments." Enter your bank account number and routing number. PSO will ask you to confirm the amount (your full bill or a fixed amount) and the day of the month you want the payment to process.

You can change the payment date, the amount, or cancel automatic payments anytime through your online account. If you cancel, you will need to make manual payments going forward. PSO sends you an email confirmation each month before the payment processes, so you can catch any errors before the money leaves your account.

Automatic payments have no fee and are the fastest way to may support your bill is paid on time every month. If your bill amount varies significantly month to month (as it often does with heating or cooling seasons), you can set a fixed amount instead of paying the full balance, though you may carry a balance forward.

Paying by Mail or in Person

If you prefer not to pay online or by phone, you can mail a check or money order to the address on your bill. Write your account number on the check. Allow 7 to 10 business days for the mail to arrive and for PSO to post the payment to your account. During that time, your account may show as past due even though your payment is in transit.

Some PSO payment centers accept in-person payments during business hours, though this option is becoming less common. Call 1-800-272-9368 to ask whether a payment center near you is still open and what hours they operate.

What Happens If You Pay Late or Miss a Payment

If your bill is not paid by the due date shown on your statement, PSO will charge a late fee (the amount varies but is typically a percentage of your bill). After 30 days past due, PSO may disconnect your service. You can avoid disconnection by calling 1-800-272-9368 to discuss a payment plan or to ask about hardship programs if you are struggling to pay.

If your service is disconnected, you will need to pay the full past-due balance plus a reconnection fee to restore power or gas. Reconnection usually takes 1 to 2 business days during normal hours, or longer if you request it on a weekend or holiday.

Using Your Bank's Bill Pay Instead of PSO's System

Many banks offer a bill pay feature that lets you schedule payments to PSO from your checking account. This is free through your bank, but the payment may take 3 to 5 business days to reach PSO, so you need to plan ahead. If you use your bank's bill pay, make sure you are sending the payment to the correct PSO mailing address (listed on your bill or on psoklahoma.com), because delays or misdirected payments can result in late fees.

PSO's direct payment system is faster and more reliable than routing payments through your bank, so if you want same-day processing, use PSO's website, app, or phone line instead.

Frequently Asked Questions

Can I pay my PSO bill with a credit card without paying a fee?

No. PSO charges a 2.5% convenience fee if you pay with a credit card through their website or phone line. You can pay with a debit card or bank account at no charge. If you want to use a credit card and earn rewards, check whether the rewards offset the 2.5% fee.

What if I pay more than I owe?

The overpayment becomes a credit on your account and is applied to your next bill. You can request a refund of the credit by calling 1-800-272-9368, though PSO may require you to wait until the balance reaches a certain threshold before issuing a refund check.

How do I know if my payment went through?

You will receive a confirmation number when ready after submitting a payment online or by phone. PSO also sends an email receipt. You can log into your account anytime to see your payment history and current balance. If a payment does not appear within one business day, call customer service at 1-800-272-9368.

Can I set up automatic payments for a different amount each month?

No. Automatic payments are for a fixed amount that you choose. If your bill varies significantly, you can set a fixed payment amount that covers most months and make manual payments for the difference, or you can make all payments manually.

What if I need to dispute a charge on my bill?

Call PSO customer service at 1-800-272-9368 to report the issue. Do not withhold payment while a dispute is being investigated, as PSO may charge a late fee. PSO will investigate and adjust your bill if an error is found.
