How to pay your Avista bill through their website

Avista's online bill pay system lets you make a one-time payment or set up automatic payments from your bank account or debit card. You log in to your Avista account, enter your payment amount and method, and the payment processes within one to two business days. The system works for electricity, natural gas, or both if you have both services with Avista.

You will need your Avista account number (found on your bill) and either a bank account or debit card. Credit cards are not accepted for online payments. If you are paying from a bank account, have your routing number and account number ready. For a debit card, you will need the card number, expiration date, and CVV.

Avista does not charge a fee for online payments made from a bank account. Debit card payments carry a fee that varies depending on the payment amount — typically between $1.50 and $3.95. The exact fee appears on screen before you confirm the payment, so you will see the total cost before committing.

Key Takeaways

  • Log into your Avista account on their website, select the payment option, and choose your payment method — bank account payments have no fee, but debit card payments do.
  • Bank account payments take one to two business days to post, so plan ahead if your bill is due soon.
  • You can set up automatic monthly payments so the same amount withdraws on the same day each month, or make one-time payments whenever you choose.
  • If you do not have online access or prefer not to use it, Avista also accepts payments by phone, mail, or in person at authorized payment locations.

Setting up automatic payments with Avista

Automatic payments withdraw money from your bank account on a date you choose each month, usually around the time your bill is due. You set this up once in your online account under the payment settings, and it continues until you cancel it. This is useful if you want to avoid late fees and do not want to remember to pay each month.

When you set up automatic payments, you choose whether to pay a fixed amount each month or to pay the full bill amount (which changes month to month). If you choose a fixed amount and your bill is higher, you will still owe the difference. If your bill is lower, the extra payment will appear as a credit on your next bill.

You can change or cancel automatic payments anytime through your online account. If you need to stop a payment before it processes, contact Avista customer service — they can halt a payment if you call before the withdrawal date, though timing depends on when the payment is scheduled.

What happens after you submit your payment

Payments made from a bank account typically post within one to two business days. Debit card payments may take slightly longer. Once the payment posts, your account balance updates and your next bill will reflect the payment. You will receive a confirmation number when ready after you submit the payment online, and you can view your payment history anytime in your account.

If you pay after your bill due date, you may be charged a late fee. Avista's late fees vary by state and service type, so check your bill or contact them for the specific amount. Paying online does not stop a late fee if the payment arrives after the due date — the due date is what matters, not when you submit the payment.

Paying by phone or mail if you cannot pay online

If you do not have internet access or prefer not to pay online, you can call Avista's customer service line to make a payment over the phone. You will need your account number and a bank account or debit card. Phone payments process the same way as online payments — one to two business days for bank accounts, and debit card fees explore.

You can also mail a check or money order to the address on your bill. Write your account number on the check and mail it to the address listed under "Pay Your Bill." Mailed payments take longer to process — typically five to seven business days from the time Avista receives it. If your bill is due soon, mailing a check is riskier because it may not arrive in time.

Some areas have authorized payment locations where you can pay in person with cash, check, or debit card. Avista's website lists these locations by zip code. In-person payments usually post the same day or next business day.

Troubleshooting common payment problems

If your payment was rejected, the most common reason is incorrect bank account or routing number information. Double-check both numbers against a blank check or your bank's website. If the numbers are correct, contact your bank to confirm the account is active and has no restrictions on outgoing transfers.

If you see a duplicate charge or a payment you do not recognize, log into your account and check your payment history. If the payment appears twice, contact Avista customer service with your confirmation number — they can investigate and reverse the duplicate if it was an error. Do not make another payment while investigating a duplicate.

If you cannot log into your online account, use the "Forgot Password" link on Avista's login page to reset it. If you do not have an online account yet, you can create one using your account number and the zip code associated with your service address. If you still cannot access your account, call customer service and they can help you set it up or troubleshoot the login issue.

Understanding Avista's payment important date and late fees

Your bill due date appears on your bill statement. Payments must post by that date to avoid a late fee. Since online and phone payments take one to two business days, you should submit them at least two business days before the due date. If the due date falls on a weekend or holiday, Avista typically extends the important date to the next business day.

Late fees vary by state and service type — some states cap late fees at a percentage of your bill, while others allow a flat fee. Check your bill or Avista's website for your state's specific late fee amount. If you are having trouble paying by the due date, contact Avista to discuss payment arrangements or hardship programs that may be available in your area.

Frequently Asked Questions

Can I pay my Avista bill with a credit card?

No, Avista does not accept credit card payments online, by phone, or by mail. You can only pay with a bank account (no fee) or debit card (with a fee). Some third-party payment processors may accept credit cards, but they charge their own fees on top of Avista's debit card fee.

How long does it take for my payment to show up on my account?

Bank account payments typically post within one to two business days. Debit card payments may take slightly longer. Mailed checks take five to seven business days from when Avista receives them. In-person payments usually post the same day or next business day.

What if I pay too much by accident?

The overpayment will appear as a credit on your next bill. You can use the credit toward future bills, or contact Avista to request a refund. Refunds are usually processed within two to four weeks.

Can I set up automatic payments for just part of my bill?

Yes, you can set automatic payments for a fixed amount less than your full bill. The remaining balance will be due on your next bill. This is useful if you want to pay a set amount each month and handle the rest separately.

What should I do if my automatic payment fails?

Contact Avista customer service when ready. They can tell you why the payment failed — usually due to insufficient funds or incorrect account information — and help you set up a new payment. You may also receive a notice in the mail if a payment fails, which will include instructions for resolving it.
