SRP's online payment options and where to find them
Salt River Project (SRP) offers three main ways to pay your bill online: through their website at srpnet.com, through their mobile app, or by setting up automatic payments from your bank account. The website and app both let you pay a one-time bill or schedule future payments. You'll need your SRP account number and a valid payment method — debit card, credit card, or bank account — to complete any online payment.
The fastest route for most people is logging into your SRP account on srpnet.com. Once you're signed in, you can see your current bill, payment history, and usage details all in one place. If you don't have an online account yet, you can create one using your account number (found on your paper bill) and your service address.
SRP does not charge a fee for paying online with a debit card or bank account. If you use a credit card, SRP passes through a processing fee that varies depending on the card type — this fee is shown before you confirm the payment, so you can decide whether to proceed.
Key Takeaways
- You can pay SRP bills online through srpnet.com, the SRP mobile app, or by setting up automatic bank transfers — all three methods are free when you use a debit card or bank account.
- Credit card payments online include a processing fee that SRP discloses before you confirm, so you can see the cost upfront.
- Setting up automatic payments means your bill is paid on the same day each month without you having to log in.
- One-time online payments typically post to your account within one business day.
Paying through the SRP website step by step
Start by going to srpnet.com and clicking "Sign In" in the top right corner. If you already have an online account, enter your username and password. If this is your first time, select "Create Account" and follow the prompts — you'll need your SRP account number and the service address on your bill.
Once you're logged in, look for "Pay My Bill" or "Payments" in the main menu. Click it and you'll see your current balance and due date. Select "Make a Payment" and choose whether you want to pay the full amount, a partial amount, or a different date. Enter the amount and select your payment method: debit card, credit card, or bank account.
If you're paying with a bank account, you'll enter your routing number and account number. If you're using a card, enter the card number, expiration date, and CVV. Review the payment details and any fees, then click "Confirm Payment." You'll receive a confirmation number on screen and by email.
Using the SRP mobile app to pay on the go
Download the SRP mobile app from the Apple App Store or Google Play Store. Open the app and sign in with the same username and password you use on srpnet.com. If you don't have an account yet, you can create one in the app using your account number and service address.
Tap "Pay Bill" or "Payments" (the exact wording varies slightly between iOS and Android). You'll see your current balance and due date. Select the amount you want to pay, choose your payment method, and review any fees. Confirm the payment and you'll get a confirmation number.
The mobile app works identically to the website — payments post within one business day and you can schedule payments in advance. Many people find the app faster for quick payments because you don't have to navigate a full website on a small screen.
Setting up automatic payments so you never miss a due date
Automatic payments remove the step of logging in each month. On srpnet.com, go to "Pay My Bill" and look for "Autopay" or "Automatic Payments." Select this option and choose your payment method — bank account or debit card (credit cards are not available for autopay).
You'll set a payment date each month. Most people choose the date their bill is due or a few days before. SRP will automatically withdraw the payment on that date from your chosen account. You can change or cancel autopay anytime by logging back into your account.
Autopay is free when you use a bank account or debit card. If you ever need to pause a payment — for example, if you're disputing a charge or waiting for a billing correction — you can turn off autopay temporarily and resume it later.
What to do if your online payment doesn't go through
If you see an error message during payment, the most common causes are a mistyped card number, an expired card, or insufficient funds in your bank account. The error message usually tells you what went wrong. Fix the issue and try again — if the payment was declined, no charge was made to your account.
If you completed the payment and received a confirmation number but don't see it reflected on your bill within two business days, log back into your account and check your payment history. Payments typically post overnight, but bank processing can take longer depending on your financial institution.
If a payment shows as pending or failed after two business days, contact SRP directly at 602-236-8833. Have your confirmation number ready if you have one. SRP can tell you whether the payment went through and help you resubmit if needed.

Other ways to pay if online doesn't work for you
If you prefer not to pay online, SRP accepts payments by phone at 602-236-8833. An automated system lets you pay with a debit card or bank account without speaking to anyone. If you need to speak with an agent, they can process payments during business hours.
You can also pay in person at SRP payment centers or authorized payment locations throughout the Phoenix area. Find the nearest location on srpnet.com under "Pay Your Bill." In-person payments are processed immediately and you'll receive a receipt on the spot.
Mail-in payments are still an option — write your account number on the check and mail it to the address on your bill. Mail payments take longer to post (typically 5 to 10 business days depending on mail delivery), so plan ahead if your due date is coming up soon.
Frequently Asked Questions
Can I pay my SRP bill with a credit card online without a fee?
No. SRP charges a processing fee for credit card payments, and the amount varies depending on your card type. The fee is shown on the payment confirmation screen before you complete the transaction, so you can see the exact cost. Debit cards and bank accounts have no fee.
How long does it take for an online payment to show up on my bill?
Online payments typically post within one business day. If you pay on a Friday evening, it may not show until Monday. Check your payment history in your online account to confirm the payment went through — the confirmation number you received is proof it was submitted.
What if I want to pay more than my current bill amount?
You can pay any amount you choose online. If you pay more than what's due, the extra amount becomes a credit on your account and will be applied to your next bill. You can also request a refund of the overpayment by contacting SRP at 602-236-8833.
Can I set up autopay with a credit card?
No. SRP's autopay option only works with bank accounts and debit cards. If you want automatic payments with a credit card, you would need to set up the recurring payment through your credit card company's bill pay feature instead.
Is my financial information safe when I pay SRP online?
SRP uses encryption and security protocols to protect your payment information. Your account login is separate from your payment data, and SRP does not store full credit card numbers after a transaction. If you have concerns about a specific transaction, contact SRP directly at 602-236-8833.
