Case Study: Roncelli Plastics achieves doubled revenue and dramatic efficiency gains with JobBOSS

Roncelli Plastics - Customer Case Study

Roncelli Plastics, a Monrovia, California plastics machine shop, faced a sharp profitability decline after 2001 that left management without clear visibility into sales rep performance, customer profitability, or job costing. Although the shop had implemented Exact JobBOSS business management software in 1994, the product was underutilized when the downturn forced leadership to rethink processes, share knowledge, and strengthen operational controls.

JobBOSS was rolled out more deeply across the company alongside lean practices, automated scheduling, and employee performance tracking, giving managers real‑time data for pricing, quoting, and shop floor priorities. The results were measurable: sales grew from $5.5M (2001) to $11.5M (2007), daily scheduling time fell from 8 to 2 hours, estimating time per job dropped from 30 to 7 minutes with a 70% improvement in accuracy, quote‑to‑order hit rate rose from 53% to 61%, on‑time delivery climbed to 97–99%, lead times shortened to three weeks or less, and the company achieved ISO/AS9100 certification — outcomes powered by JobBOSS.
