Time Clock for Machine Shops: What to Look for and What to Avoid

A time clock for a machine shop is a system that records when workers start and stop work, ideally with job attribution at clock-in. The basic function — tracking hours per worker for payroll — is handled by many tools. The job-level attribution that makes a time clock useful for job costing and scheduling is handled by far fewer.

FabWise includes a shop floor kiosk purpose-built for this environment.

What Machine Shop Time Clocks Need to Handle

Machine shop environments create specific requirements that generic time clocks don't address:

Job attribution. Workers in a machine shop are assigned to specific jobs — customer orders, production runs, maintenance work. A time clock that records only "worker clocked in at 7:02 AM" doesn't tell you which job received those hours. You need attribution at clock-in: worker selects the job (from an active job list) and the task type before the segment starts.

Multi-job shifts. Machine shop workers frequently move between jobs within a single shift. A tool that captures a single job per shift requires end-of-shift reconstruction for workers who split their time. A tool that supports clock-out/clock-in sequences as the worker changes jobs captures the split accurately, in real time.

Shared terminals. Machine shops don't typically provide individual devices to floor workers. One or two shared terminals — ruggedized, mounted, accessible — serve the whole floor. The terminal needs to handle rapid multi-user flows: worker identifies themselves, clocks in, clears; next worker identifies themselves, clocks in.

Environmental durability. Machine shop floors are not office environments. Terminals collect grease, metal dust, and coolant mist. Touch screens need to work through gloves. The physical setup needs to survive the environment.

What to Avoid

Systems that don't capture job at clock-in. If the time clock captures hours per worker but not hours per job, you'll be reconstructing job attribution manually. Any reconstruction is estimation. Estimation accumulates error over time.

Manual reconciliation at pay period end. Some systems require supervisors to manually review and reconcile time records before payroll. This is a symptom of inadequate capture upstream — either clock-out data is missing, or job attribution is incomplete. Reconciliation work that exceeds 30 minutes per pay period is a sign the capture system isn't working correctly.

Systems that separate "payroll time" from "job time." In a machine shop, every labor hour should be attributed to a job. If your time clock produces a payroll file but doesn't feed job cost data — or produces job cost data that doesn't reconcile with payroll — you have two systems where one would do. See labor tracking for how a unified approach works.

Over-engineered enterprise systems. Full ERP-integrated time and attendance systems are designed for manufacturers with hundreds of employees and complex shift patterns. For a machine shop with 5–50 workers, they bring overhead (implementation cost, training, admin burden) that isn't justified by the problem being solved.

Features Worth Having

Active job list at clock-in. Workers select from a list of open jobs administered by the shop manager. The list is current because the manager adds jobs when orders come in. Workers aren't entering job codes from memory; they're selecting from a filtered list.

Task type at clock-in. Beyond which job, the clock-in should capture what type of work — machining, setup, inspection, rework. This is what enables task-level analysis in job costing: not just "how many hours on Job A" but "how many setup hours on Job A" vs. "how many machining hours."

Supervisor correction with audit trail. Workers select wrong jobs, forget to clock out, or need times adjusted. A supervisor should be able to attach a correction to any record — adjusted value, reason, their name — without destroying the original capture. The original and the correction both matter for audit.

Real-time floor visibility. The admin view should show current floor status without requiring a report to be run: who's clocked in now, to which job, for how long.

FabWise for Machine Shops

FabWise is built for fabrication, metalworking, and machine shops specifically. The kiosk time clock runs on a shared terminal on the shop floor; workers identify with a PIN, select job and task, and clock in. Supervisors see floor status in real time. At pay period close, the payroll export produces files for ADP, Gusto, QuickBooks Payroll, or a custom CSV. The same records feed job costing.

FabWise is not an ERP, not an HR system, and not a scheduling tool. It captures labor time accurately and exports it to whatever systems consume that data.

Frequently Asked Questions

What's the difference between a time clock and a time tracking system?

A time clock is the physical or digital device workers interact with to clock in and out. A time tracking system is the full software — data storage, reporting, export, correction workflow. FabWise is the full system; the kiosk is the shop floor interface for it.

Can a machine shop use a standard time clock app?

Standard time clock apps are designed for individual workers using personal devices. They don't handle shared terminal flows, don't capture job attribution, and aren't designed for multi-job shifts. They'll give you payroll hours but won't help with job costing.

How many workers does FabWise support?

FabWise is designed for shops with 5–100 workers. It runs as a multi-tenant SaaS; the kiosk terminal handles 20–50 daily clock-ins without performance issues.
