How to Track Employee Hours: 5 Methods Compared (2026)

Small businesses track employee hours in one of five ways: paper timesheets, spreadsheets, a punch clock, a time clock app on employees’ phones, or a shared tablet kiosk at the workplace. For a US team of 10 to 50 hourly workers, a time clock app is the best fit, with phones for anyone who works off-site and a tablet kiosk by the door for everyone who starts the shift in one place, because it records the exact punch time, totals hours and overtime for you, and hands payroll a file instead of a stack of cards to retype. Below: the five methods side by side, what federal law says you must keep, and a setup plan for a 15-person team.

The five ways to track employee hours

1. Paper timesheets

Employees write start, break and end times on a sheet, a manager signs it, and someone adds up the hours on payroll day. The cash cost is near zero. The real cost is hours written from memory, corrections nobody can read, and totals added by hand and retyped. Fine as an outage backup, hard to run for 10 or more hourly people. See how to switch from paper timesheets.

2. Spreadsheets

A spreadsheet is good enough when one person types in hours for a few people and nobody is near overtime. For 10 to 50 hourly workers it usually is not: times are still typed in after the fact, a broken formula fails silently, and the sheet cannot show who is on the clock right now. Watch the time math too: 7 hours 45 minutes is 7.75 hours, not 7.45 (the hours to decimal converter does it for you).

3. Punch clock hardware

A wall-mounted card machine or terminal stamps the time when someone inserts a card, swipes a badge or types a PIN. The stamp is accurate, but cards still get totaled by hand, anyone can punch a coworker’s card, and it only works for people who start at that door. Fingerprint and face terminals cut buddy punching but bring biometric consent laws such as Illinois BIPA into play.

4. A time clock app on employees’ phones

Each person clocks in and out from their own phone. The app records the time on the server, can stamp where the punch happened, and totals hours and overtime as the week goes. It is the only method that works for people who start at a client’s home, a job site or a second location. See how a clock in clock out app works.

5. A shared tablet kiosk

One tablet by the door runs a kiosk app, and employees punch with a PIN or a printed badge. Nobody needs a personal phone, which matters where phones stay in lockers or not everyone has a smartphone. It is the software version of the old punch clock. See kiosk clock-in with QR badges.

The five methods compared

Most teams of 10 to 50 mix a kiosk for people who start at the building with phones for people who don’t. What matters is that both feed one timesheet: one set of hours to approve, one file for payroll.

What the law requires you to keep

The Fair Labor Standards Act (FLSA), the federal wage and hour law, does not tell you how to track time. The Department of Labor’s Fact Sheet #21 says employers may use any timekeeping method they choose, as long as it is complete and accurate. What the law sets is what each record holds and how long you keep it. Under 29 CFR Part 516, for each nonexempt employee you keep:

• Name, address, sex, occupation, and birth date if under 19
• The day and time the workweek begins
• Hours worked each day and each workweek
• Pay basis, regular rate, and straight-time and overtime earnings per week
• Additions to and deductions from wages
• Total wages per pay period, the pay date, and the period covered

Keep payroll records at least 3 years and the records wages are worked out from (time cards, rate tables, schedules) at least 2 years. Many states ask for longer, so 3 years for everything is the simple rule. Detail is in time and pay records requirements and FLSA basics for small business.

Rounding and breaks

Rounding. Federal rules accept rounding punches to the nearest 5 minutes, tenth of an hour or quarter hour, but only if it averages out so people are paid for all the time they work (29 CFR 785.48). Rounding that always favors the employer fails that test, and some states are stricter: in 2021 the California Supreme Court ruled in Donohue v. AMN Services that employers cannot round meal period punches. With a digital clock, no rounding is the simplest safe choice.

Breaks. Federal law does not require breaks. But rest breaks of usually 20 minutes or less count as paid work time, and a meal break (typically 30 minutes or more) can be unpaid only when the employee is completely relieved from duty (DOL Fact Sheet #22). Many states require breaks, so record when each one starts and ends instead of deducting a flat 30 minutes. See the rules for California and New York.

How to set up hour tracking for a 15-person team

Picture a 15-person restaurant, clinic or cleaning company: 12 hourly staff, 2 shift leads and the owner.

1. 01

   Write down your workweek and pay period

   Record the day and time your workweek starts and how often you pay. Overtime counts per workweek: weeks of 35 and 45 hours mean 5 hours of overtime, even on a two-week pay period.
2. 02

   Choose how each role punches

   Staff who start at the building use a kiosk by the door. Anyone who drives to clients or job sites uses the phone app. One system, one timesheet.
3. 03

   Set the rules before the first punch

   Overtime threshold (40 hours a week federally, plus any state daily rule), rounding (none is simplest), which breaks are paid, and what happens when someone forgets to clock out.
4. 04

   Add the team and hand out kiosk PINs

   Import a spreadsheet of names or send invites, then give kiosk users a PIN or badge. Count managers and the owner too: most tools price by headcount.
5. 05

   Publish a one-page clock-in policy

   When to punch, how breaks work, how to ask for a fix. Start from our clocking in and out policy.
6. 06

   Test, then run one pay period in parallel

   Have two people punch a few shifts, including a break and one deliberate missed clock-out, and check the totals. Then keep the old method for one pay period, compare, and retire it.
7. 07

   Review weekly, not on payroll day

   Clear missed punches and late arrivals, approve each timesheet, then export. The routine is in time card approval.

How hours get to payroll

Payroll needs each person’s regular hours, overtime hours and rate for the period, in decimal hours. There are three ways to get it there:

• Retype it. Total each sheet or card and key it in, one error-prone keystroke at a time. The clock in clock out calculator helps while you are still on paper.
• Upload a file. The time clock exports a CSV in the layout your payroll provider imports. The usual route for small teams.
• Sync over an API. Some tools push hours straight into payroll. You still approve the hours first.

Either way, run payroll from approved hours only, so a missed clock-out never becomes a 16-hour shift on a paycheck.

Common mistakes

• Auto-deducting a 30-minute lunch whether or not it was taken.
• Editing punches with no record of who changed what, or why.
• Averaging overtime across a two-week pay period.
• Not paying for opening tasks or a required pre-shift meeting before clock-in.
• Throwing out time records before 3 years are up.
• Assuming nobody buddy punches. See how to stop buddy punching.

How ClockOut does it

ClockOut is the time clock we make. Here is what it does and which plan each part needs, checked against the product on October 15, 2026. The manager side is covered on the time and attendance system page.

• Phone app and web (all plans). Employees clock in from the iPhone or Android app or any web browser.
• GPS stamp at the punch (all plans). Each clock-in and clock-out records the coordinates and address. No location trail is kept, on or off the clock (see location privacy). Geofence enforcement is Starter and up.
• Offline punches (all plans). With no signal, a clock-in or clock-out is saved on the device with the original tap time, syncs on reconnect, and is flagged for a manager. Punches queued over 48 hours are rejected; breaks need a connection.
• Kiosk with PIN or QR badge (Starter and up). Staff punch on a shared tablet with a 4 to 6 digit PIN or a printed QR badge. The optional clock-in photo is a plain snapshot, not face recognition.
• Exception inbox (Starter and up). Missed punches, no-shows, late arrivals, early leaves, break problems, off-site punches and auto clock-outs in one list.
• Timesheet approval (Starter and up). Employees submit their week; a manager approves it or sends it back with a reason.
• Overtime alerts (Starter and up). The employee and their managers get a notice before the weekly threshold, 5 hours before it by default.
• Rounding, paid breaks, edit history (all plans). Rounding is off or to the nearest 5, 15 or 30 minutes, applied to each shift’s worked time; exact punches are kept. New accounts start with no rounding, so pay uses exact minutes unless you pick an increment in Settings. Up to 60 break minutes per shift can be paid. Manager edits need a reason and keep the before and after times.
• Payroll files. A generic hours CSV on every plan. Pro adds pay runs (draft, approve, lock, export) and payroll-ready CSV files in RUN Powered by ADP, Gusto and QuickBooks formats. There is no API push: you download the file and upload it. See payroll export formats.

Owners and managers count as people. What ClockOut does not do: process payroll, keep a location trail between punches, or scan fingerprints or faces. If you want one vendor to track time and cut paychecks, choose a tool with payroll built in.
