You can move from paper timesheets to a digital time clock in about a week, if you do it in order. Load your staff and sites, pick a punch method that suits each site, and set your overtime, break and rounding rules before anyone clocks in. Train staff in short sessions, then go live while keeping paper running alongside until the end of your first full pay period. Compare the two line by line before you pay. The worked example below shows why: an "8 to 5 every day" paper sheet and the clock record can differ by most of an hour in a single week, and the difference doesn't always go the way you'd expect.
Rules on keeping time records, rounding, breaks and overtime vary from place to place. This guide explains a practical way to switch systems. It isn't legal advice. For the exact rules where you work, check with your labour department.
1. Before Day 1: collect what you have
Most of the work in a smooth launch is gathering information you already have, scattered across files and people. Before you start, collect:
- A current staff list: names, departments, job titles, pay rates, pay type (hourly or salaried) and start dates.
- Your sites: every place staff start work, including any that move, such as building sites or client homes.
- Your current rules, even the unwritten ones: when overtime starts, how breaks work, what happens when someone forgets to sign the sheet.
- Your pay calendar: the pay period, the week start day and the next three pay dates.
- The last two or three paper timesheets, to test your rules against real weeks.
Pick a go-live date at the start of a pay period, or at least the start of a week. Going live in the middle of a week means one week's overtime is split between two systems.
2. Day 1: staff, sites and pay details
Load your staff list and sites into the new system. Check every person against your payroll, not against memory.
- Every active employee is there, and nobody who has left.
- Each person has the right department, pay rate and pay type.
- Each site has a clear name staff will recognise ("Main kitchen", not "Site 3").
- Each person has a way to identify themselves when they punch: a PIN, a card or tag, a phone login.
3. Day 2: choose how each site punches
There's no single right way to clock in. Choose per site, based on how people arrive.
| Site type | Good fit | Why |
|---|---|---|
| One entrance, fixed hours | A shared device by the door with a PIN, QR code or card | Quick, nothing for staff to carry or install |
| Staff on the move | A phone app with location checks | Punch at the client's site, not the office |
| Office or reception desk | Clock in at the computer | Already at a screen all day |
| No signal or power at times | A device that stores punches and syncs later | Punches aren't lost when the connection drops |
Two questions to ask for every site:
- Does everyone have what the method needs? A phone app only works for staff with a suitable phone. Have a fallback, such as a shared device, for anyone who doesn't.
- How will you know it's really them? If buddy punching is a risk, a photo, a phone in hand or a location check helps. Our guides to stopping buddy punching and geofence time tracking go into the options, and choosing a time clock compares them.
Install and test each device on Day 2: power, connection, a test punch in and out. See ways to punch for what's possible.
4. Day 3: set the rules before go-live
Paper hides rules. A digital system applies them to every minute, so set them carefully before the first punch. Test each rule against one of the old paper weeks you collected.
Overtime
Set the limit (per day, per week or per pay period), the rate (for example 1.5×), any second band (for example 2× over 48 hours), and the week start day. Our overtime guide shows how much the counting period changes pay.
Breaks
Decide whether staff punch out for breaks, or a fixed unpaid break is taken off each shift, and for which shift lengths. Punched breaks are more accurate. A fixed deduction is simpler but must be adjusted when someone works through their break. See our guide to breaks and rest.
Rounding
You can pay to the exact minute, or round clock times. If you round, round evenly in both directions. For example, to the nearest 15 minutes:
- In at 8:07 rounds to 8:00. In at 8:08 rounds to 8:15.
- Out at 5:52 p.m. rounds to 5:45. Out at 5:53 rounds to 6:00.
Over time, even rounding roughly balances out. Rounding that always favours the employer doesn't, and in many places it isn't allowed. Rounding every clock-in up and every clock-out down can easily take 15 minutes a day from someone. Over a 5-day week that's 1.25 hours, or US$ 15.00 at US$ 12.00 an hour, for every person, every week.
Grace and early starts
Decide whether minutes before the scheduled start are paid, and how many minutes after the start still count as on time. Write both down.
5. Day 4: train staff and supervisors
Training is short, but do it in person if you can, in groups of no more than ten.
For staff (15 minutes):
- Why you're switching: accurate pay, no lost sheets, overtime paid properly.
- How to clock in and out, and how to record breaks.
- What to do if they forget to punch or the device is down.
- What's recorded, and when. If location is checked at clock-in, say so plainly.
- Everyone does one test punch in and out before they leave.
For supervisors (30 minutes): how to see who's in, how to fix a missed punch (with a reason), how to approve overtime, and who to call when something breaks.
6. Day 5: go live, with paper alongside
On go-live day, everyone clocks in on the new system and fills in the paper sheet as usual. Keep both going until the end of your first full pay period.
It feels like double work, and for a couple of weeks it is. But the parallel run is what lets you pay the first period with confidence. If the two records disagree, you'll have both in front of you to work out which is right.
Be visible on Day 5. Stand by the shared device at the main start time, answer questions, and fix PINs and logins on the spot.
7. Days 6 and 7: fix exceptions every day
Each morning, look at the previous day's exceptions:
- Missing punches: an in with no out, or an out with no in.
- Very long or very short shifts: often a forgotten clock-out.
- Punches at the wrong site, or no site at all.
- Breaks that are missing, or far longer than allowed.
Fix each one the same day, while people still remember, and record the reason for every edit. A habit of daily checks in the first week saves hours at the end of the pay period, and shows staff the system is being watched fairly.
8. Compare paper and digital: a worked example
At the end of the first pay period, compare the paper and digital hours for every person before you pay.
Devon is paid US$ 12.00 an hour, with overtime at 1.5× over 40 hours a week. His paper sheet says "8 to 5, 1 hour lunch" every day: 8 hours × 5 days = 40.00 hours. Here's what the clock recorded:
| Day | In | Out | Break | Hours |
|---|---|---|---|---|
| Mon | 8:05 | 5:05 p.m. | 60 min | 8.00 |
| Tue | 8:00 | 6:30 p.m. | 60 min | 9.50 |
| Wed | 8:20 | 5:05 p.m. | 60 min | 7.75 |
| Thu | 8:00 | 5:00 p.m. | 30 min | 8.50 |
| Fri | 8:00 | 4:00 p.m. | 60 min | 7.00 |
| Total | 40.75 |
The paper sheet hid four things: a late start on Wednesday, a late finish on Tuesday (a delivery), a short lunch on Thursday, and an early finish on Friday (a doctor's appointment). Some went in Devon's favour, some didn't. They don't cancel out.
- Paper: 40.00 hours × 12.00 = US$ 480.00.
- Clock: 40.00 × 12.00 = 480.00, plus 0.75 overtime hours × 18.00 = 13.50. US$ 493.50.
A US$ 13.50 difference for one person in one week. Across a team, and a year, it's real money, in both directions.
For each difference you find, decide which of three things happened:
- The clock is right. The paper was rounded or filled in from habit. Pay from the clock.
- The paper is right. Someone forgot to punch, or punched at the wrong time. Fix the punch, with a reason.
- A rule is wrong. For example, the break deduction doesn't match how breaks really work. Fix the rule, and re-check everyone it affects.
When the differences left are explained and small, stop the paper.
9. Common pitfalls
- Setting rules after go-live. Every punch before the fix is worked out under the wrong rule.
- Going live mid-week or mid-period. Overtime gets split across two systems.
- No plan for forgotten punches. Without a simple fix process, staff go back to writing times on paper.
- Edits without reasons. Every change to a time record should show who made it, when, and why. Our guide to time records and the law explains why it matters.
- Overnight shifts. Check that a 10 p.m. to 6 a.m. shift lands as one 8-hour shift on the right day and in the right week.
- Staff left out. Someone without a suitable phone, or a site without power, ends up back on paper. Plan a fallback for every person.
- Stopping paper too early. Run in parallel for one full pay period, even if the first week looks perfect.
10. Your seven-day launch checklist
- Before Day 1: staff list, sites, current rules, pay calendar and recent paper sheets collected; go-live date set at the start of a period.
- Day 1: staff and sites loaded and ticked off against payroll; everyone has a way to identify themselves.
- Day 2: punch method chosen and tested at every site, with a fallback for anyone it doesn't suit.
- Day 3: overtime, break, rounding, grace and early-start rules set and tested against an old paper week.
- Day 4: staff and supervisors trained; everyone has done a test punch; one-page sheet at every device.
- Day 5: live on the new system, with paper still running.
- Days 6 and 7: exceptions checked and fixed daily, with a reason for every edit.
- End of first pay period: paper and digital compared for every person, differences explained, then paper stopped.
11. Frequently asked questions
How long does it take to switch from paper timesheets?
For a small or mid-sized business, about a week to set up and go live, then one full pay period running paper alongside before you rely on the new system alone.
Should we run paper and digital at the same time?
Yes, for one full pay period. It lets you compare the two before you pay, and fix punches or rules while you still have both records.
Is rounding clock times allowed?
In many places, yes, if it's even-handed: rounding both up and down to the nearest interval. Rounding that always favours the employer is often not allowed. Paying to the exact minute avoids the question.
What if some staff don't have smartphones?
Give them another way to punch, such as a shared device with a PIN, QR code or card at the site. Mixing methods within one business is normal.
What if someone forgets to clock in or out?
Have a simple process: they tell their supervisor the same day, the supervisor fixes the punch, and the reason is recorded.
Why are the digital hours different from paper?
Paper is often filled in from habit ("8 to 5") rather than the real times. The clock records late starts, late finishes and short breaks that paper misses, in both directions. ---
Want paper gone by next payday?
PunchClock lets staff clock in on a phone app with a geofence check, at a shared device with a PIN, QR code or tag, or from a desktop with a PIN. Every punch is time-stamped to the minute, you can load your staff list from a spreadsheet, and payroll applies your overtime limits from the hours recorded.
