THORNTON, Colo. (CBS4) – The City of Thornton is warning utility customers about how they pay their bill online.

“We got alerted to this by some of our customers who thought they had submitted payments and weren’t sure if they had posted to their accounts,” said Todd Barnes, a city spokesman.

The co-founder told CBS4 the company has 50,000 users in the Denver area and they pay 1,400 companies in the region, some of the largest being Denver Water and Xcel Energy.

Roger Parks said Doxo is a company that allows people to pay all their bills from one simple site. Some accounts are charged but some are not.

The section on Doxo for Thornton utilities has the city’s official logo.

“They’re not affiliated with us, they do provide a legitimate service but what we need people to know is there’s a much easier way to pay your utility bill to the City of Thornton and that’s directly through us,” Barnes said.

Fine print on the website says Doxo doesn’t own the logos it uses. Parks says the company doesn’t buy keywords or advertise.

CBS4 searched several other municipalities and while you can pay your bill through Doxo, only Thornton’s portal came up on the first page of web results.

It has raised questions if customers know what they’re signing up for, but Doxo says there are checks and balances so customers know what they’re agreeing to.

“The City of Thornton always wants to make it easy to pay your utility bill with us and we’re not going to charge you a fee. And we guarantee it’s going to post directly to your account,” Barnes said.

  1. I disagree that Thornton’s Paymentus portal would solve the problem. I have encountered two sources of confusion that have caused me to question whether my payments are being applied.

    #1. If you use budget billing, the portal tells you your true-up amount as the amount due, not the budget-billing negotiated amount. You have to pull up your actual bill to see this value. Prior to migrating to the Paymentus system, this was never a problem.

    #2. Twice now, one page of the portal has said I am overdue on a payment, while another page reports all payments are up-to-date. This means the home page of the portal ALWAYS says I am late on my last month’s bill. When I call in to Thornton Water, they concur I’m up-to-date. It takes months to resolve the problem.

    I have used Thornton’s website to pay bills for years now, and the move from their old system to the new Paymentus system has been nothing but a pain for me. If you would consider it a failure to migrate to a system that doesn’t have the features you used to have; and of the features it does keep, it can’t get critical features right… Well Thornton Water’s migration to Paymentus would qualify.
