You can pay a DEMCO bill as a guest by visiting the payment portal directly, without logging in or setting up an account.

DEMCO (Dairyland Energy Cooperative) operates in Wisconsin and allows one-time payments through their online system without requiring you to create a user profile. This route works if you want to pay a single bill quickly, or if you prefer not to store payment information with the cooperative.

The guest payment option is faster than account creation but gives you fewer tools — you cannot set up automatic payments, view past bills, or check your usage history without logging in. If you plan to pay multiple bills over time, creating an account takes about five minutes and gives you more control.

Key Takeaways

  • DEMCO's guest payment portal lets you pay without creating an account, using your account number and bill amount.
  • You will need your DEMCO account number (found on your bill) and a valid payment method — debit card, credit card, or bank account.
  • Guest payments process immediately for card payments and within one to two business days for bank transfers.
  • If you pay the same bill twice by mistake, contact DEMCO's billing department to request a refund or credit.
  • Creating a free account takes five minutes and lets you set up automatic payments, which some people find more convenient than paying each month manually.

How to find the DEMCO guest payment page

Start at DEMCO's main website and look for a link labeled "Pay My Bill" or "Make a Payment." This link usually appears in the top navigation or footer. Click it, and you should see two options: "Log In" and "Pay as Guest." Select "Pay as Guest."

If you cannot find the guest payment link on the main site, try searching "DEMCO pay bill guest" in your browser. The direct payment portal URL may change, so searching is often faster than guessing the web address.

What information you need before you start

Have your DEMCO bill in front of you. You will need your account number, which appears near the top of the bill, usually next to your name or address. You will also need the amount due — this is the total you owe, not just the service charge.

You will need a payment method: a debit card, credit card, or bank account (routing number and account number). DEMCO may charge a small fee for credit card payments but not for debit cards or bank transfers. Check the payment page for current fees before you confirm.

Step-by-step: paying as a guest

On the guest payment page, enter your account number exactly as it appears on your bill. Then enter the amount you want to pay. If you want to pay the full amount due, type that number. If you want to pay a partial amount, you can do that too — DEMCO will accept any amount as long as it is at least the minimum shown on the page.

Next, select your payment method and enter the details. For a card, you will type the card number, expiration date, and CVV (the three-digit security code on the back). For a bank account, you will enter your routing number, account number, and account type (checking or savings).

Review the payment summary to make sure the account number, amount, and payment method are correct. Then click "Submit" or "Confirm Payment." You should see a confirmation number on the screen — write this down or take a screenshot. DEMCO will also send a confirmation email to the address you provide.

How long it takes for the payment to show up

If you pay with a debit or credit card, DEMCO usually posts the payment to your account within one business day. If you pay with a bank transfer (ACH), it typically takes one to two business days. During weekends and holidays, processing may take longer.

Your confirmation number proves you paid, even if the payment has not yet appeared on your bill. If you do not see the payment posted after three business days, contact DEMCO's billing department with your confirmation number and they can look it up.

What to do if you pay the same bill twice

If you accidentally submit the payment twice — for example, if you thought the first one did not go through — contact DEMCO's billing department as soon as you realize the mistake. Have both confirmation numbers ready. DEMCO can either refund the duplicate payment or apply it as a credit to your next bill, depending on what you prefer and their policy at the time.

Do not wait to report a duplicate payment. The sooner you contact them, the faster they can process the correction.

When to create an account instead

If you pay your DEMCO bill every month, creating a free account takes less time than logging into the guest portal each time. An account lets you set up automatic payments, which means DEMCO withdraws the amount due on a date you choose — usually around your bill due date. You can change or cancel automatic payments anytime.

An account also lets you view your billing history, check your current usage, and see your payment schedule. Some people use this to spot billing errors early or to understand why their bill went up. If you think you might need any of these features, account creation is worth the five minutes it takes.

Frequently Asked Questions

Can I pay a DEMCO bill by phone without creating an account?

Yes. Call DEMCO's customer service number (listed on your bill) and tell them you want to make a one-time payment. They will take your payment information over the phone. This method is slower than the online guest portal but works if you do not have internet access or prefer to speak with someone.

What if I do not have my account number?

Your account number is on your bill, but if you do not have a recent bill, call DEMCO's customer service. They can look up your account using your name and address. Have your address and phone number ready when you call.

Does DEMCO charge a fee for guest payments?

DEMCO may charge a processing fee for credit card payments but typically not for debit cards or bank transfers. The fee amount and which payment methods incur it can change, so check the payment page before you submit. The page will show the fee before you confirm.

Can I set up automatic payments without creating an account?

No. Automatic payments require an account so DEMCO can store your payment method and schedule. Creating an account is free and takes about five minutes. Once your account is set up, you can turn automatic payments on or off anytime.

What if the guest payment page is not working?

If the page loads but will not accept your information, try a different browser or clear your browser's cache and cookies. If it still does not work, call DEMCO's customer service — they can process your payment over the phone or help you troubleshoot the online system.
