How Precision Manufacturing Eliminated All Payroll Errors Across 3 Shifts
A Detroit automotive parts manufacturer running 24/7 operations with 86 workers and complex pay rates went from weekly payroll errors to zero discrepancies.
The Company
Precision Manufacturing Co. produces automotive parts across two plants in the Detroit metropolitan area. They run three rotating shifts around the clock, with 86 production workers, quality inspectors, and shipping staff.
Carlos Mendez manages both plants. His teams operate on rotating 8- and 12-hour shifts with different pay rates based on role, shift differential, and certifications. Payroll was a constant source of errors and grievances.
"Three shifts, two plants, and six different pay rates. Something was always wrong."
Manual time tracking couldn't handle the complexity. Overnight shifts that crossed midnight were miscalculated. Shift differentials were applied inconsistently. Certified welders who switched lines didn't always get the right rate.
Carlos estimated 8% of every payroll run contained errors. Some overpaid, some underpaid. The union filed grievances, and HR spent hours on corrections.
"We were running our factory with precision machinery and tracking our workforce with paper and pencil. That disconnect was costing us $50K a year in hidden labor costs."

Rotating shifts with different pay rules
Why they chose Timedox
Carlos needed a system that understood rotating shifts, overnight crossovers, and multiple pay rates. Timedox's flexible shift rules handled all three out of the box.
"I set up our three shift patterns, assigned the pay rates by role and certification, and Timedox did the rest. Overnight shifts calculate correctly. Shift differentials apply automatically. It just works."
Fingerprint time clocks at every plant entrance eliminated the last-mile problem: workers clocking in or out at the wrong time, or having colleagues punch for them.

Any shift pattern: rotating, fixed, split, overnight. All handled automatically.
Multi-Rate Pay
Different rates by role, shift, and certification. Overtime auto-calculated.

For the first time in anyone's memory, payroll ran with zero errors. No grievances filed. HR spent 3 hours on payroll instead of 12.
Production costing enabled
Carlos started mapping hours to production runs and work orders. For the first time, he could see the true labor cost of each product line.
