Where Trusted Legacy Meets Modern Efficiency

For more than 70 years, Iverson’s Lumber has been a trusted supplier of premium building materials across Michigan. Founded in 1950, the family-owned company serves contractors, remodelers, and homeowners from its Highland and Montrose locations, offering everything from framing lumber and decking to windows, doors, hardware, and trim packages.

As one of the state’s most established lumber and building material (LBM) providers, Iverson’s built its reputation on quality, customer service, and deep product expertise. But as project volume and competition increased, the company faced a familiar challenge across the industry: maintaining fast, accurate estimating while keeping internal costs under control.

The Challenge: A Bottleneck in the Bids

In today’s construction environment, responsiveness is everything. Contractors expect fast, accurate takeoffs, and even small delays can mean losing bids or damaging relationships.

Iverson’s internal estimating team was already operating at full capacity. Every new project strained turnaround times further, especially during peak building seasons. Hiring additional full-time estimators wasn’t a cost-effective option, and leadership wanted a more flexible way to expand estimating bandwidth without overextending the team.

Estimating Bottlenecks

Without adequate bid capacity, Iverson's was losing out on potential projects and profits.

Staffing Shortages

Iverson's internal staff were stretched thin trying to keep up with growing demand

Labor Costs

Hiring additional full-time estimators wasn’t financially practical

The Solution: Embracing A New Way to Estimate

In 2025, Iverson’s partnered with TSARSI to add a dedicated, engineer-degreed estimator to their operations—someone who would integrate directly into their systems and processes as an extension of the existing team.

Rather than outsourcing sporadic work, this partnership provided full-time estimating support that was consistent, reliable, and aligned with Iverson’s internal standards.

The results that followed were immediate, and extraordinary.

Keys to Integration Success

To make the transition seamless, TSARSI took time to understand Iverson’s estimating process, product catalog, and communication flow. The result was an integrated solution that fit naturally into their business operations and required no disruption to existing systems.

Alignment with Iverson’s takeoff templates, pricing, and product catalog
Familiarity with leading estimating software tools and digital plan review workflows
Direct communication with the in-house team for project handoffs and clarification
Scalable structure that allowed more bids without additional full-time hires

This approach enabled Iverson’s to increase capacity instantly while maintaining quality and consistency across all takeoffs.
