At KLAS, our mission is straightforward—we seek to improve the world’s healthcare through insights, collaboration, and transparency. At the heart of that mission is the desire to facilitate improvement. We aren’t here to just measure or report on the performance of healthcare IT vendors. Our goal is to help make them better, thereby helping improve healthcare overall.
Measuring Improvement
Each February, KLAS releases the annual Best in KLAS report, which documents customer satisfaction with hundreds of software and services offerings used by provider and payer organizations. But the report isn’t just a static snapshot in time. Through it, KLAS seeks to also examine how the customer experience with each vendor has evolved over the year, with the hope being that things have changed for the better. To that end, in addition to the Best in KLAS designation awarded in individual categories, KLAS also recognizes the solutions and services whose customers have reported the most improvement since the previous year’s report.
Who Was Most Improved in 2026?
The improvement we seek to celebrate doesn’t happen by accident. We acknowledge the vendors below for being willing to listen to customer feedback and make adjustments where needed. Check out the full 2026 Best in KLAS Awards: Software & Services report to see full details about how these and other vendors perform.
Note: The designation of “most improved” is given to the software and services offerings that saw the highest percentage increase in score from the previous year’s Best in KLAS report. To be eligible, an offering must have been a ranked solution both years, and customer feedback collected by KLAS must confirm that the improvement was the result of intentional product or relationship changes.
Most Improved Software Product: TeleVox HouseCalls Pro
Citing meaningful progress in the vendor’s service maturity, reliability, and customer partnership, TeleVox HouseCalls Pro customers have seen a 22% improvement in satisfaction over the past year. Customers say the improvement has been driven by more proactive communication, stronger executive engagement, and tangible follow-through on long-standing issues. Respondents note that change management (previously a pain point) has improved as TeleVox now provides proactive outreach and regular, organization-specific updates, particularly when customers adjust workflows or processes.
Voice of the Customer
“The solution has come a long way within the last year. It is better now than it has ever been, and the vendor is moving in the right direction. TeleVox is showing us what they potentially have in terms of upgrades. They have also shown us a lot of new functionalities, like self-scheduling options and AI technology. . . . Also, things like pulling a report or looking up a patient complaint are super easy in the system. I am super happy with TeleVox right now.” —VP/other executive, October 2025
Most Improved Physician Practice Solution: Greenway Health Greenway Revenue Services
Greenway Health has taken critical customer feedback to heart in recent years and worked to improve partnership with their revenue cycle management clients. Respondents report meaningful improvements to Greenway Health’s account management, claims follow-up, and collaborative support, resulting in a 24% increase in customer satisfaction among Greenway Health’s RCM services clients since last year’s Best in KLAS report.
Voice of the Customer
“The services have improved tremendously since we got a new revenue cycle manager. They are very attentive to our needs and the issues that arise within our practice. They are very knowledgeable regarding the different systems we use and all the processes that link everything together. They have been and continue to be an asset to our practice. Other people from the firm have helped us in recent months and have worked on helping us improve various issues.” —Office manager, December 2025
Most Improved Services Solution: PwC ERP Business Transformation & Implementation Leadership Services
Clients of PwC’s ERP business transformation and implementation leadership services have reported meaningful gains in satisfaction over the last year, leading to an 8% increase in satisfaction. Respondents describe PwC as having a prescriptive, highly engaged, and outcomes-driven approach. They value the firm’s deep system expertise as well as PwC’s commitment to go beyond transactional delivery and establish themselves as a true strategic partner.
Voice of the Customer
“PwC was very logical and rational. They brought real-life experiences and brought the right people at the right time to really help us make good decisions and move our project along. . . . If we asked a question that could have been considered out of scope, it was never treated that way. . . . PwC made us feel that they were putting our interests before their own. We truly have a partnership.” —CEO, December 2025
Continuing the Cycle
At KLAS, improvement is the goal. We hope vendors whose customers report a less than satisfactory experience will use the Best in KLAS report to spark greater collaboration and transparency. Any vendor who is willing to work for it has the potential to be counted among next year’s “most improved,” or perhaps even be named Best in KLAS!
