About The UltimateIDX™

The UltimateIDX™ is a consortium of REALTORS® and programming engineers that have specialized in the real estate industry for decades.

Our previous President Rhonda McMillan, was one of the first Missouri Real Estate Brokers to recognize the potential of the Internet and had her husband Mack create her first real estate website in 1994. At the time Mack owned and operated an AT&T Service Bureau but soon closed shop to work with Rhonda at the family operated real estate office as a licensed real estate Broker.

Rhonda continuously searched for better systems to manage her real estate leads on her #1 ranked real estate site for Missouri. All applications failed to deliver as promised and came up painfully short of what Rhonda felt was required to assist Agents in lead and time management.

Mack began testing MLS/IDX systems in early 1998. In 2000 he became a consultant for the MLS Committee at the South Central Board of REALTORS® in Rolla Missouri. It was there that he that he formed UltimateIDX™.

A New Real Estate Portal

The Brokers Edge was launched in 2005 to serve as a real estate portal and repository for industry tools and software. With the time constraints created by her Brokerage growth of TBE was admittedly slow, but steady. “As we continued to add staff we were starting to see a snowball effect on TBE” said Rhonda.

It was Rhonda’s vision to see The Brokers Edge become a complete real estate portal offering one-stop shopping for real estate Agents looking for real solutions at an affordable price. Unlike other portals we did not discourage competing vendors from offering products and/or services. In fact we encouraged it. Rhonda felt that true competition increased quality while reducing prices.

In early January of 2009, the UltimateIDX™ and The Brokers Edge Inc. formally split and parted ways.

The Ultimate Client Resource Manager

While the UltimateIDX™ has been in various stages of development since 2000, it was not formally launched until 2006. In 2008 the team at the UltimateIDX relocated to Las Vegas Nevada for better access to local networks and trained staff.

Both the UltimateIDX™ and UltimateRETS™ systems have successfully and securely managed thousands of real estate leads and have assisted Agents in closing millions of dollars in real estate transactions. We would love to help you do the same.


Our Corporate Officers and Board Members were all previously REALTORS® and truly understand the industry and the needs of fellow REALTORS® There is no longer a need to settle for IDX or RETS systems that were designed by software engineers or webmasters that don’t measure up. Our staff knows what it takes to sell real estate for a living. We have done it for decades. Don’t settle for what someone that is clueless about our industry thinks we need. We can show you a better way.

Integrated IDX and CRM

In 2016 UltimateIDX became part of the Blue Fire Group. This union has allowed the UltimateIDX solution to continue to offer not only one of the most advanced IDX/ RETS solutions with great lead capture and SEO, but now also includes a comprehensive Lead Management system that is tightly integrated to the IDX and website experience of Buyers.
