The fastest way to pay TXU is online through their website or mobile app, by phone, or by setting up automatic payments from your bank account
TXU Energy customers in Texas can pay their bill through several channels, and the method you choose depends on how quickly you need to pay and whether you want to set it up once or manage it monthly. Each option takes a different amount of time and offers different protections against late fees.
The online portal at txu.com is available 24 hours a day. You log in with your account number and password, enter a payment amount, and choose a payment date. The system accepts bank account transfers (which are free) or credit and debit cards (which carry a processing fee). Payments made before 5 p.m. Central Time on a business day typically post the same day.
The TXU mobile app offers the same features as the website and works the same way. If you prefer to speak with someone, you can call TXU's payment line at 1-888-889-8898 to pay by phone using a bank account or card. Automatic payments, set up through your online account or by phone, deduct money on a date you choose each month and eliminate the risk of forgetting a payment.
Key Takeaways
- Online and mobile app payments are free when you pay from a bank account, but credit or debit card payments include a processing fee that TXU discloses before you confirm.
- Payments made before 5 p.m. Central Time on a business day post the same day; payments after that or on weekends post the next business day.
- Automatic payments remove the need to remember your due date each month and help you avoid late fees if you set the payment date before your bill is due.
- Your account number appears on your paper bill or in your online account, and you will need it to pay by phone or to log into the website.
Paying online through your TXU account
Go to txu.com and select "Pay My Bill" or "Make a Payment" from the homepage. Enter your account number and the password you created when you registered. If you have not registered, you can create an account using your account number and the service address on your bill.
Once logged in, you will see your current balance, due date, and payment history. Select the amount you want to pay (you can pay the full balance, the minimum, or a custom amount) and choose your payment date. TXU allows you to schedule a payment up to 30 days in advance, which is useful if you want to pay on a specific date but do not have the money available yet.
For payment method, choose between a bank account (free) or a credit or debit card (fee applies). TXU will show you the exact fee before you confirm the payment. Bank account payments are processed through the Automated Clearing House (ACH) system and typically post within one business day. Card payments may post faster but cost more.
Using the TXU mobile app
Download the TXU Energy app from the Apple App Store or Google Play Store. Log in with the same account credentials you use on the website. The app displays your balance, due date, and recent payments in the same format as the website.
Tap "Pay Now" or "Make a Payment," enter the amount, select your payment date, and choose your payment method. The app works identically to the website, so there is no advantage to using one over the other except convenience — use whichever you check more often.
Setting up automatic payments
Automatic payments deduct money from your bank account on a date you choose each month, usually a few days before your bill is due. This removes the risk of accidentally missing a payment and triggering a late fee. You can set up automatic payments through your online account or by calling TXU at 1-888-889-8898.
To set up automatic payments online, log into your account, go to "Billing & Payments," and select "Autopay" or "Automatic Payments." Choose the date you want the payment to come out (TXU recommends a date before your due date), confirm your bank account information, and save. You can change or cancel automatic payments at any time through the same menu.
If you set up automatic payments by phone, a representative will confirm your bank account details and the payment date before processing the request. Automatic payments are free and use your bank account, so there is no processing fee.
Paying by phone or mail
To pay by phone, call 1-888-889-8898 and have your account number ready. A representative will ask which payment method you want to use (bank account or card), the amount you want to pay, and the date you want it processed. Phone payments are available Monday through Friday, 7 a.m. to 7 p.m. Central Time, and Saturday, 8 a.m. to 5 p.m. Central Time.
Mailing a check is slower but avoids processing fees and does not require you to share your bank account or card information. Write your account number on the check and mail it to the address printed on your bill. TXU typically receives mailed payments within 5 to 7 business days, so mail your payment at least 10 days before your due date to avoid a late fee.
Understanding payment timing and due dates
Your bill shows a due date, which is the last day TXU will accept payment without charging a late fee. Payments made online or by phone before 5 p.m. Central Time on a business day post the same day. Payments made after 5 p.m. or on weekends post the next business day. Mailed checks take 5 to 7 business days to arrive, so the actual posting date is later than the date you mail it.
If you miss your due date, TXU will add a late fee to your next bill. The amount varies but is typically a percentage of your balance. If you are unable to pay by the due date, contact TXU immediately to discuss payment arrangements or hardship programs that may be available in your area.
What to do if your payment does not post
If you made a payment online or by phone and it does not appear in your account within the expected timeframe, log into your account and check your payment history. Payments usually show as "pending" for one business day before they post as "completed." If more than two business days have passed and the payment still shows as pending, or if it does not appear at all, contact TXU customer service at 1-888-889-8898.
Have your account number, the payment amount, and the date you made the payment ready when you call. A representative can look up the payment in their system and tell you whether it was processed. If the payment was lost, TXU can resubmit it or process a new one. Keep a record of your confirmation number (provided when you make an online payment) in case you need to reference it later.
Frequently Asked Questions
Is there a fee to pay my TXU bill online?
No fee applies if you pay from a bank account. Credit and debit card payments include a processing fee that TXU discloses before you confirm the payment. The fee is typically 2 to 3 percent of the payment amount, though the exact percentage depends on the card type and TXU's current rates.
Can I pay my TXU bill before I receive my bill in the mail?
Yes. You can log into your online account at any time to see your current balance and make a payment. You do not have to wait for the paper bill to arrive. The online account updates regularly and shows your balance, usage, and due date.
What happens if I set up automatic payments but want to skip a month?
Log into your account and temporarily pause automatic payments for that month, then resume them the following month. You can also contact TXU at 1-888-889-8898 to make changes by phone. If you pause automatic payments, remember to make a manual payment by your due date to avoid a late fee.
