Who knew one of the beneficiaries of the energy boom in the Mountain West would be Mint Bills?

Intuit’s Mint Bills today announced a partnership with natural gas utility Questar Gas that will provide online and mobile billpay services to almost one million customers in Idaho, Montana, and Utah.

Brad Markus, general manager for customer service at Questar Gas, said that while providing a wide variety of payment options was a priority for his customers, pedigree was also important. “Mint Bills was the perfect partner for us. We not only liked the mobile bill pay product, but also that it’s a part of Intuit, a trusted brand,” he said.

Utility companies have been an area of focus for Mint Bills for years. In addition to its new partnership with Questar Gas, Mint Bills is working with two other players in the natural gas world, UGI Utilities and New Jersey Natural Gas, providing multichannel billpay for more than two million households combined.

Steve Schultz, general manager of biller services for Mint Bills, said, “Given the increasing adoption of mobile devices, we’re seeing more natural gas utilities starting to offer electronic payment options for their customers.” Schultz added that the cost-effectiveness of Mint Bills was also a big factor for utilities companies like Questar, which are looking for mobile payment technology “for little to no cost.”

Mint Bills makes it easy for consumers to manage and pay their bills. The app monitors all connected accounts—savings, checking, credit—and provides configurable alerts to let users know when bills are nearing due dates. Users can sign up online, or download the iOS or Android versions to use the mobile app.

Mint Bills was launched by Intuit late last year, following the company’s acquisition of Check (formerly Pageonce) in May 2014.
