Case Study: Jackson & Blanc achieves 90% reduction in timekeeping hours and $52K annual savings with Rhumbix

Jackson & Blanc - Customer Case Study

Jackson & Blanc, a San Diego mechanical contractor founded in 1931 with 125+ employees, faced major inefficiencies from 100% pen-and-paper timekeeping: superintendents spent over 10 hours weekly manually consolidating timesheets and fixing errors. To modernize and win broad adoption across both tech-savvy and veteran staff, they evaluated and selected Rhumbix’s digital field solution, Rhumbix Core.

Jackson & Blanc ran a month-long trial and rolled out Rhumbix Core company-wide within three months, going fully paperless and linking field and office time reporting. Rhumbix delivered rapid adoption and measurable impact—what had taken about 10 hours per week per foreman now takes one hour, saving roughly $1,000 per week (about $52,000 per year), while improving timesheet accuracy and consistency.
