Case Study: The Oswald Company boosts estimating accuracy and speeds workflow with ProEst

How ProEst helped estimators transition from Excel to the cloud

Oswald, a Cincinnati-based mid-size construction and design-build firm with a 4–6 person pre-construction team, faced inconsistent estimating, inefficient reporting and delays from relying on Excel. After a six-month evaluation of products that integrated with Procore, Oswald selected ProEst’s cloud-based estimating platform to replace spreadsheets and standardize their pre-construction workflow.

ProEst performed a soft in‑house rollout with live training and responsive support, fully integrating estimates with Procore and eliminating duplicate data entry. The result: Oswald moved almost entirely off Excel, gained near-instant data transfer (seconds instead of hours or days), improved estimate accuracy and accessibility, and positioned the company for significant growth—including projected revenues toward $110M and forecasted company growth of 20–25% by 2025.
