How to digitize construction timesheets

Digitize construction timesheets by deciding what each entry must capture (worker, job, cost code, hours, and classification on public work), choosing crew-based or individual clock-in, adding a daily foreman approval, and exporting approved hours straight to payroll and job costing.

To digitize construction timesheets, replace the paper sheet with a phone or kiosk entry that captures who worked, on which job, on which cost code, and for how long, then route it through a foreman's daily approval and send approved hours directly to payroll and job costing. The goal is not just to get rid of paper. It is to get labor hours by cost code into the PM's hands during the week, while there is still time to fix a crew that is running over budget.

What the law requires (and does not)

Under the Fair Labor Standards Act, the U.S. Department of Labor says employers must keep accurate records for each non-exempt worker, including identifying information, hours worked, pay rates, overtime, deductions, and pay dates. The DOL also says the Act "requires no particular form for the records," and employers may use any timekeeping method, such as a time clock, a timekeeper, or employee self-reporting, as long as it is complete and accurate. In other words, digital timesheets are fine, provided the hours are right.

The DOL fact sheet says payroll records must be kept for at least three years, and records used to compute wages, such as time cards and work schedules, for two years. Many states set their own recordkeeping, meal break, and overtime rules, and public prevailing wage work adds certified payroll requirements, so check your state as well. See how to do certified payroll step by step for the public-work side.

Decide what each time entry must capture

Fields for a construction time entry
FieldWhy it matters
WorkerPayroll and recordkeeping
Date, start, stop, breaksHours worked and overtime; state meal and rest rules
JobJob costing and billing
Cost codeLabor tracking against budget by activity
Classification (public work)Correct prevailing wage rate for the work performed
Equipment used (optional)Equipment costing on the job
Per diem or travel (optional)Reimbursements and job cost
Notes or photo (optional)Proof of extra work for T&M billing

Keep the required list short. Every extra required field adds friction at 5 p.m. The construction timesheet template is a good starting layout.

How to digitize timesheets in 7 steps

  1. Clean up your cost codes first. If foremen face 200 codes, they will pick the first one. Give each crew a short list of codes for the current phase. How to build a construction cost code structure helps.
  2. Choose crew entry or individual clock-in. Crew entry (the foreman logs everyone) is fast and suits crews that move together. Individual clock-in from each worker's phone or a site kiosk gives more accurate start and stop times and reduces disputes. Many contractors use crew entry with each worker confirming their own hours at the end of the week.
  3. Decide on location features. GPS stamps and geofences can confirm a clock-in happened at the job. Tell workers what is recorded and why, and check your state's rules on location tracking before turning it on.
  4. Set the approval flow. Foreman approves daily, PM reviews cost codes weekly, payroll locks the week. Edits after approval should leave a record.
  5. Connect to payroll. Approved hours should export to your payroll system or service without retyping. Check that overtime, classifications, and multiple rates come across correctly.
  6. Connect to job costing. The same hours feed labor cost by job and cost code, so the PM sees budget against actual during the week.
  7. Run one pay period in parallel, then stop paper. Compare the app's totals with paper for one cycle, fix gaps, and set a firm date after which paper is not accepted.

Worked example: a 35-person concrete contractor

Say a concrete contractor has five crews on three to six jobs a week. Paper timesheets come in Monday morning, the office manager keys about 175 worker-days of entries, and roughly one sheet in ten needs a phone call to decode a job or code. Payroll goes out, but the PMs do not see labor by cost code until the following week, after the slab is already poured.

After the switch, foremen enter crew time on a phone at the end of each day, choosing from 8 to 12 codes set for the current phase (forms, rebar, place and finish, strip). The foreman approves on the spot. By Tuesday afternoon, the PM sees that the Building B footing crew has used 210 of 240 budgeted forming hours with a third of the footings still to form. The PM moves an extra carpenter to the crew and asks the foreman about the delay, a week earlier than paper would have allowed. Monday payroll entry drops from most of a day to a review of exceptions.

Using digital time for more than payroll

Once hours are digital and coded, the same records answer questions that paper never could. Three uses pay off quickly:

  • Time and materials billing. Hours tagged to extra work, with a note or photo, become backup for a T&M invoice or a change order instead of a reconstruction from memory.
  • Estimating feedback. Actual hours per unit (per square foot of formwork, per fixture, per opening) flow back into the estimating database so the next bid uses real production rates.
  • Disputes. When a GC questions a back charge or a sub's manpower, dated, approved time records by area are far stronger evidence than a reconstructed sheet.

Mistakes to avoid

  • Rounding and default hours. An app that defaults everyone to 7:00 to 3:30 produces neat but inaccurate records. Make start and stop times real entries.
  • Shared logins on one phone. Each worker or foreman needs their own login so entries are attributable.
  • Ignoring classifications on public work. A worker who runs equipment for half a day and labors the rest may need hours split by classification. See how to handle dual classification on prevailing wage jobs.
  • Editing approved time without a record. Changes should show who, when, and why.
  • No backup plan for dead phones. Give foremen a simple fallback, such as entering the crew's time the next morning with a note.

Tools, templates, and related guides

Before buying anything, map your current process with the construction timesheet template. Pair the rollout with how to get field crews to use construction apps and how to calculate labor burden for construction workers, since accurate hours only help if the cost per hour is right. Related terms: labor productivity, cost code, and certified payroll.

Frequently asked questions

Are digital timesheets legal for construction payroll?

Yes. The Department of Labor says the FLSA requires no particular form of records, and employers may use any timekeeping method as long as it is complete and accurate. State rules may add requirements.

How long do I need to keep construction time records?

Under the FLSA, the DOL says payroll records must be kept at least three years and time cards and other wage computation records two years. State law and public contracts can require longer.

Should foremen enter time for the whole crew?

Crew entry is fast and common. Many contractors add a weekly confirmation by each worker, or individual clock-in, to reduce disputes over hours.

Can digital timesheets handle prevailing wage jobs?

Good systems let you record classification for each block of hours, which is needed to pay the right rate and to prepare certified payroll.

What is the hardest part of switching from paper timesheets?

Usually the cost codes. If the code list is long or unclear, digital entries will be just as unreliable as paper. Clean it up first.
