Time Theft in Construction: How Subcontractors Stop It

Time theft in construction means getting paid for time that was not worked, or time that was charged to the wrong job. It is often not dramatic fraud. More often it is a missed punch, a timecard filled in from memory on Friday, or a crew’s hours dropped on whatever job code came to mind. The fix is not tighter surveillance. It is a timekeeping system that verifies who worked, where, and on what, plus a short daily review of the exceptions before payroll runs.

This guide is written for commercial subcontractors in the United States. It covers what time theft looks like on a real job, what it does to your numbers, which controls work, where federal wage-and-hour rules set limits, and how to roll out a policy without losing your crews.

TL;DR

• Time theft covers buddy punching, padded timesheets, early clock-ins, long breaks and hours left on the wrong job or cost code. Honest mistakes produce the same bad data as deliberate fraud.
• The real damage goes past payroll. Bad time corrupts job costing, production data, change order support and your next bid.
• No single control is enough. Combine location checks, individual worker identity, locked audit trails and a daily foreman review of exceptions.
• Under the FLSA you stay responsible for accurate records, even when employees enter their own time. Rounding and “7-minute rule” shortcuts can create wage liability.
• Pilot on one project, review exceptions daily, then audit trends by worker, foreman, project and cost code.

What time theft looks like on a commercial job site

The term sounds like a character issue. In practice, it is a set of timekeeping failures, some intentional and many not. DOL guidance on recordkeeping makes clear that the employer is the one who must keep accurate records of hours worked, which is why the patterns below matter to you as the owner or project manager.

The forms you will meet most often:

• Buddy punching. One worker clocks in or out for another. It is common where a crew shares a kiosk, a shared PIN or a single foreman phone.
• Padded or falsified timesheets. Hours added at the end of the week, or tasks reported on a day the worker was not there.
• Early in, late out. Punching in from the parking lot, the truck or home, then walking to the work area.
• Extended breaks. Fifteen minutes that quietly becomes thirty, repeated daily.
• Personal activity while clocked in. Errands in a company truck, long calls, or a side job.
• Wrong job or cost code. Hours left on the job the worker was on yesterday, or spread evenly across jobs because it is easier.
• Memory-based entries. Time reconstructed on Friday for a week of work. Nobody is lying on purpose, but the numbers are fiction.

That last pair is what we call time slippage, and for most subcontractors it costs more than outright fraud. It also explains why the first rule of any review is to treat an exception as something to investigate, not as proof of misconduct. A punch from the wrong location can be an honest mistake.

Why it costs more than the extra paid minutes

If you think of time theft as a small payroll discrepancy, you will under-invest in fixing it. The wider impact looks like this:

1. Inflated payroll. You pay for hours that were not productive on your work.
2. Distorted job costing. Labor hours land on the wrong project, so one job looks profitable and another looks like a loser.
3. Wrong production data. If 400 hours were logged against a task that took 320, your unit rates for the next estimate are off.
4. Weaker change order support. When you need to prove extra labor on a T&M ticket or a change order, padded or vague time makes your documentation less credible to the general contractor.
5. Overtime exposure. Extra hours that tip someone past 40 in a workweek become overtime you must pay.
6. Worse bids. Estimators build the next bid from the last job’s actuals. Contaminated actuals produce a bad price, and you may not discover it until the job is underwater.

The strongest business case for fixing time theft is data integrity. The goal is not catching dishonest workers. It is producing project records you can trust when you bid, bill and forecast cost to complete.

Broader industry figures on the cost of time theft exist, such as one monitoring vendor’s compilation of statistics that cites a nationwide annual figure attributed to the American Payroll Association. Treat numbers like that as directional. What matters for your company is what your own exceptions report shows.

Matching the problem to the control

Different forms of time slippage call for different tools. Here is how we map them.

The pattern in that table is the point. GPS verifies a device’s location but not necessarily who is holding it. Identity checks do not prove the worker is at the correct job. Exception review is what ties both to payroll accuracy.

The controls that work together

Location verification

GPS punch location and job-site geofencing tell you where a punch happened. They are useful, with a caveat that many buyers miss: a geofence does not necessarily block an off-site punch. Depending on the system, it may block, flag, or just remind the worker. Before you rely on one, test the exact behavior. Try punching from outside the fence, with the phone offline, from a browser, and after editing a past entry.

For a closer look at how fences behave for small crews, see our piece on geofencing time tracking for small construction teams.

Worker identity

Shared PINs are the weak link. Give each worker an individual login or PIN, and consider punch photos or biometrics only where your policy, your crews and your state’s rules allow it. Identity checks stop one worker from covering for another. They say nothing about whether the punch was at the right place, which is why you pair them with location.

Required job and cost-code selection

Most slippage in a subcontractor’s books is not stolen time at all. It is time assigned to the wrong place. Make job and cost-code selection part of the punch, keep the code list short enough that a worker can pick one with gloves on, and review it regularly. We cover the code structure in labor cost codes for subcontractors.

Offline capability

Job sites have basements, rural areas and steel decks with no signal. If a system fails without a connection, workers will write the time down and enter it later, which is the memory-based entry you are trying to eliminate. Check how your tool handles offline time tracking for construction field teams before you commit to it.

Locked audit trails

Every edit should be recorded: who changed what, when, and why. Keep the underlying history, approvals, corrections, job assignments and the payroll export, not only the final edited timesheet. That protects you in a wage dispute and in a conversation with a general contractor about backup for T&M work.

Review exceptions daily, not weekly

Blanket surveillance is the wrong answer. Construction has legitimate irregularities: dead phone batteries, poor connectivity, crews moved to another location, early material deliveries and transfers between projects. A system that flags every one of them as theft trains supervisors to ignore alerts. The better approach is to surface anomalies and preserve explanations.

The routine is short. Each day, while the facts are fresh, the foreman reviews:

• Missed punches
• Off-site punches
• Unexpected overtime
• Overlapping entries
• Hours on a job the worker was not scheduled for
• Manual edits

The worker gets one documented correction path: they explain, the foreman approves or rejects, and the reason is recorded. Payroll receives approved time, never raw submissions. Our guide to mobile foreman timecard approvals that lock payroll shows how that looks in the field.

When reviewing anomalies, keep real site conditions in the picture. A crew that punched late because the work area was blocked, or a delivery that arrived before the shift, is a scheduling problem, not a conduct problem. Our partner-free advice here is simple: ask what happened on site before you ask who is to blame. Resources on construction schedule delays can help you separate site-caused lost time from genuine time slippage when you read an exceptions report.

The legal guardrails every subcontractor should know

This is general information for planning, not legal advice. For specific situations, such as a wage claim, a union agreement or a state with stricter rules, talk to an employment attorney or your state labor department.

You own the records

Under the Fair Labor Standards Act, employers may choose any timekeeping method, including time clocks, timekeepers or employee-entered time, but the method has to produce accurate records. Hours worked each workday and total hours each workweek generally must be recorded for covered nonexempt employees, and the Department of Labor says required records generally must be kept for three years, per Fact Sheet #21. The practical lesson: you cannot defend inaccurate records by pointing to a worker’s own entry, and you should not silently edit one either.

Rounding and the “7-minute rule”

People often ask about the 7-minute rule. It is not universal permission to erase seven minutes of work. Federal practice allows rounding to the nearest five minutes, one-tenth of an hour or quarter hour, but only when the practice averages out so employees are fully paid over time. A DOL opinion letter on rounding discusses that position. In a quarter-hour system, 1 to 7 minutes may round down and 8 to 14 minutes round up, but state law, collective bargaining agreements and how you actually apply it can impose stricter requirements. Work done before or after scheduled hours must still be counted.

Rounding is a pay-fairness tool, not a productivity control. If your rounding systematically produces unpaid minutes, it creates wage-and-hour liability. Many subcontractors avoid the question by recording exact punch times.

Clocking in and waiting time

The DOL has addressed the time workers spend clocking in and out. A recent opinion letter, FLSA2026-8, discusses when that time is and is not compensable, including waiting in line to clock in and out. If your site requires parking in a remote lot and a shuttle ride, as some workers describe in online forums, read your state’s rules and ask counsel before deciding how to treat that time. Your written policy should say when the paid day starts.

Salaried employees

You may track the hours of salaried employees, and it often helps job-cost accuracy. A salary alone does not make someone exempt: classification depends on the salary-basis and duties tests. If a salaried worker is nonexempt, you must record hours accurately and pay overtime when it is due. The Department of Labor’s guidance on exempt status and recordkeeping explains that recordkeeping is lighter for properly exempt employees.

Discipline without retaliation

Your policy should separate intentional falsification from ordinary correction, and it should protect any worker who reports accurate time. If you suspect a worker of deliberate padding, document the pattern, give them a chance to explain, and apply the policy the same way to everyone. Consistency is your best defense.

A rollout plan that crews will accept

The quickest way to lose a crew is to announce “we are tracking you now.” Present it as a way to get everyone paid correctly and to stop arguments about hours. A defensible rollout follows these steps.

1. Write the rules. Cover shift start and end, travel, mobilization, breaks, project changes, missed punches, corrections and approvals. Say plainly where the paid day begins.
2. Train the crews. Show a worker how to punch, switch jobs and request a correction. Do it in the language they work in.
3. Configure jobs and cost codes. Keep the list short and tied to how you bill and estimate.
4. Pilot one project. Pick one foreman and one job. Our write-up on a one-foreman pilot for crew time tracking explains how to run it.
5. Review exceptions daily. Use the list above, and keep notes on what keeps recurring.
6. Reconcile to payroll and job cost. Approved time should match what payroll pays and what the cost report shows.
7. Audit trends. Look by worker, foreman, project and code. A pattern across one foreman’s crew is a process problem. A pattern around one worker is a conversation.

Our perspective: fix the system before you blame the crew

We built Won2Build from a working subcontractor’s point of view, and what we see again and again is that most “time theft” is a design problem. A crew that fills in hours on Friday is not stealing, it is guessing, and the guess flows into payroll, job cost and the next estimate. We would rather make the right behavior the easy behavior: punch from the phone, pick the job, let the foreman approve the day before anyone goes home.

We also believe in proportion. A tool that treats every worker as a suspect creates distrust and a pile of alerts nobody reads. A short list of real exceptions, handled the same day, does more than a dashboard of everything. The point of controlling time is protecting your margin and keeping honest crews from being measured against sloppy data. When field time and office numbers agree, you can price change orders with confidence and bid the next job from real actuals.

Where Time Budge fits

If you want one place to run this routine, Time Budge is our labor tracking and job cost tool for subcontractors, built around field punches, job and cost-code selection, and foreman approval. It is $199 per month per company, plus $2 per month per active field worker, as listed on our pricing page. It works with the rest of the Won2Build Hub, so the same login carries you into change orders and bids without double entry.

FAQ

What is it called when an employee steals time?

It is most often called time theft or time fraud. The label covers buddy punching, falsified timesheets, extended breaks and clocking time that does not match the work performed. Some of it is deliberate, and some is honest error that produces the same bad data.

How do I prevent time theft on a construction site without making crews feel watched?

Use verification and exception review rather than constant monitoring. Give each worker an individual login, capture punch location, require a job and cost code, and have the foreman review flagged items daily. Explain that the goal is accurate pay and accurate job records.

Is it legal to track salaried employees’ hours?

Yes. Employers may track salaried employees’ hours, and it can help job costing. A salaried employee is not automatically exempt from overtime, so if the person is nonexempt you must record hours accurately and pay overtime when required.

What is the 7-minute rule?

It is shorthand for quarter-hour rounding, where 1 to 7 minutes round down and 8 to 14 round up. It is acceptable under federal guidance only if the practice averages out and employees are fully paid over time. State law and union agreements may be stricter, and work actually performed must be counted.

How long should I keep time records?

The Department of Labor says required FLSA records generally must be kept for three years. For construction, keep the audit history, approvals, corrections, job assignments and payroll export as well as the final timesheet, since your state may set longer periods.
