About Us

Mark Systems - 35 Years of Developing Home Builder Software


ECi Mark SystemsTM is a leading provider of simple, visual, social, and mobile home builder software solutions, offering best practices based on NAHB recommendations and real-world applications.

IHMSTM is the home building industry’s only single-database, ERP information management application, and one of the most widely used, industry-specific software products available for home builders.

Through the use of interactive maps, LotVueTM allows developers and builders to easily visualize lot inventory, construction progress, sales status, budget and schedule variances, architectural and other vital information.

Utilizing a single database throughout the system, real-time access from anywhere provides residential builders state-of-the-art efficiencies in reporting and customer service. Complete integration assures reliable accuracy from sales through construction.



Our Mission Statement is simple:

“Improve bottom line revenue for our builder customers through tools and services that improve operational efficiency and reduce costs.”

Since 1983, Mark Systems has been exclusively focused on the development of software tools focused on a single industry: residential builders and developers. We serve no other industries; we have no outside investors or stockholders; we have no performance pressures other than those originating from our customer base.


From the newest intern to the senior consultants, every ECi Mark Systems, Inc. employee understands that, to continue to be successful, our only alternative is to service our customers beyond their expectations.

While every company touts itself as a ‘customer centric’ organization, ECi Mark Systems, Inc. “puts its money where its mouth is.” Our business model is one of partnership with our customers, and our licensing terms reflect that.

Since IHMS software is licensed on a per-unit basis, our performance and financial future is intrinsically linked to that of our customers: we’re only paid if the customer continues to use our software to profitably build houses. This fact filters down into every aspect of ECi Mark Systems, Inc. business. Barriers to entry are lower for IHMS  and LotVue than with virtually any other competing products. And while this is good news for the customer, it means that there is only a limited “sunk cost” incentive for any given customer to stay with the software.

Every ECi Mark Systems, Inc. employee understands this as a fact of life. Across the organization, every employee understands that we have to remain engaged with every customer continuously. Mark Systems consistently gets the highest marks for its customer service and support team, reflecting that philosophy.



ECi Mark Systems, Inc. is an intensely focused organization with one goal: to increase our home builder clients’ profitability by reducing construction costs, increasing sales, improving productivity, and enhancing communication. Current product offerings include IHMS™ home builder software and LotVue™ interactive community maps.

IHMS offers ERP support for every home building activity, delivering full back-office and field operations directly to every person in the building process, using their desktop, laptop, or hand-held device. 

LotVue visually displays data on interactive community maps, including lot inventory, construction progress, sales status, budget and schedule variances, architectural and other vital lot information.

Despite our national scope, ECi Mark Systems, Inc. retains the culture of a regional software developer. Every Mark Systems employee, from executives to interns, establish a relationship with clients that drives our development and ensures our growth.
