What 18 Real Construction Companies Reveal About Faster Bids, Better Accuracy, & Higher Win Rates
Preconstruction speed matters, but speed by itself is not the goal. The real value comes when faster takeoffs also improve estimate accuracy, increase bid volume, and help contractors win more profitable work. Across 18 STACK customer stories spanning flooring, roofing, plumbing, interiors, exteriors, general contracting, and suppliers, that pattern shows up again and again. We converted STACK customer case studies into a structured dataset: the Preconstruction Efficiency Benchmarks.
What Does the Dataset Show?
First, time-to-bid improvements are not marginal.
ProFormance Builder Solutions cut a complex workflow from four hours to ten minutes, increased capacity by 25% without adding headcount, and raised proposal output from 10 to 30 per day. Executive Flooring cut a complex job from two hours to five minutes. Keller Construction reduced takeoff time by 25%. The TPH Group cut takeoff time by 40%. Gen X reported 50% time savings. Ken’s Discount Building Materials says it cut takeoff time by 75% or more, and Lakefront Roofing Supply says work that once took a couple of days can now be done in about 1.5 hours.
“ProFormance cut complex estimating from 4 hours to 10 minutes and increased proposal output from 10 to 30 per day.”

Second, faster estimating unlocks more bidding capacity.
ProFormance Builder Solutions went from 10 to 30 proposals per day. Gen X doubled bid submissions. Exterior Wholesale Supply increased bid submissions by 20% to 40%. Denver Winwater says it now produces more quotes per day, totaling $300 million in quotes in 2023. Stonebrook Exterior also links higher estimator output to increased sales.
“Denver Winwater produced $300 million in quotes in 2023.”

Third, the outcomes are not just about speed.
They also point to better accuracy and stronger commercial performance. The TPH Group says STACK improved accuracy, doubled win rate, and helped drive 700%+ revenue growth, from $1 million in a year to $2 million for the quarter. Everflow Plumbing says better accuracy and more bidding led to a 30% higher win rate and $1.5 million in additional revenue. SimplyDoors reports a 30% win-rate increase and 600% year-over-year growth. Journey Flooring reports a 10% to 15% win-rate increase and doubled revenue in 1 to 1.5 years.
“Everflow Plumbing increased win rate by 30% and generated $1.5 million in additional revenue.”

Fourth, not every case study publishes the same level of detail, and that matters.
Some stories give exact before-and-after numbers, while others emphasize qualitative gains like improved collaboration, easier onboarding, better data standardization, or fewer errors and less rework. Elemex, for example, reports 25% to 30% productivity gains and 15% annual work-volume growth, while CentiMark Corporation focuses more on estimating flexibility, API-connected workflows, and data standardization at enterprise scale. Kinzler Construction Services emphasizes ERP integration, time-saving features, and improved accuracy.
“Ken’s Discount Building Materials cut takeoff time by 75% or more.”

Methodology
The Preconstruction Efficiency Benchmarks dataset was compiled from 18 publicly available STACK customer case studies. Each record standardizes published outcomes into comparable fields such as trade, revenue band, company size bucket, time-to-bid change, estimate accuracy change, bid-volume change, win-rate change, and revenue impact. When a case study did not publish a numeric value for a field, that field was marked “Not disclosed” rather than estimated. Source links are included for every record.
