What our customers are saying
Hear from some of our customers. We work with 95 of the top 200 building companies.

Guy Dark
Vice President of Purchasing
BuildTopia is pretty easy to use. We run our entire business through it. Without it, we back to spreadsheets and phone calls.

Whitney Pryor
Inbound Marketing Manager
NHLS has been a game changer for our marketing department! The team at NHLS has worked tirelessly to make sure we were able to integrate our website with our builder management system … We were able to easily communicate with the team our specific use case scenarios and the output was an intuitive, user-friendly software that makes the daily workload as home builder marketing professionals much easier!

Brett Taylor
CEO/Founder
We are excited for the 3 year partnership with NHLS. We see the long term potential for this web destination and feel it fills a void for consumers in the market place. We at Red Tree believe this will help us connect with the new buyers marketplace on a different level than we are used to. It's going to be an exciting 3 years!

Kimberly Bianchi
Decor Studio Manager
My team at Opus Homes is incredibly impressed with NEWSTAR Design Studio Manager software. As a home builder, a segment of our business revolves around our Decor Studio. The "wish list" feature really helped narrow down exactly what our clients wanted for their home based on price, aesthetics and overall appeal.

Louis Tancredi
Corporate Controller
Our Design Consultants have now completed 100 charts with ease and ability to create addendums while performing color appointment. This has been made so easily accessible with Design Studio Manager.

Linda Rempel
Customer Care Manager
When our buyers see that there is a comprehensive, engaging program in place, it gives them immediate confidence in their purchasing decision, and shows them that we care. Homeowner Central helps us create a more productive building process, streamline warranty requests, raise customer satisfaction, and ultimately, scale our business with confidence.

Chris Colbeck
VP Sales & Marketing
The Homeowner Central platform will positively impact almost all facets of our business, from how we engage and interact with our homeowners to how we are perceived as an industry innovator. But more importantly it will allow us to provide an enhanced home ownership experience and allow our residents to better understand and enjoy their home.

Don Forsgren
President & CEO
Intracorp is committed to providing an extraordinary experience to our Homeowners. Our partnership with Homeowner Central by CONASYS and its Homeowner Portal platform adds to this experience, providing a market leading tool for Homeowners to have an always-available, resource for accessing information on their individual home.

Todd Everest
Director of Construction
We could not do what we do without BuildTopia. This system puts real-time information the hands of our superintendents, trades, and back here in the office. This sounds straightforward but it’s crucial. Our team is always on the same page.

Karen Dresher
Director of Operations
The most cutting-edge technology and tools are ineffective without skilled hands to operate them effectively. We now have the tools to be the most efficient builder in Arizona, and our team is committed to using these tools to build incredible, top-quality homes for our customers.

David Grant
Owner
Our relationship with Constellation HomeBuilder Systems goes beyond software. Constellation has been with us every step of the way. Every time we had a problem, they had a solution that was personalized for our needs. From BuildSoft, to Builder360 and now NEWSTAR, we have been able to operate more efficiently to further strengthen our businesses.

Brent Dunham
Director of Purchasing
NEWSTAR is built on builder best practices. Because we came in on the ground floor with Homes by West Bay, we were able to create a structure to build on. NEWSTAR helps us analyze our business, make informed decisions, access real-time information, and achieve a level of efficiency that simply wasn’t possible before.
