Why paper timesheets cost builders a day a week

Paper timesheets cost builders a day a week because the same hours are collected, chased, decoded, checked and entered several times. On a 50-person site, that work can easily fill eight hours before payroll is even finalised.

The day disappears in small pieces

No one normally sits down and says, “I spent all day on timesheets.” The time is scattered across the week.

A supervisor reminds workers to fill in Friday’s sheet. The site administrator checks missing start and finish times. Payroll calls about an unclear “7” that might be a “1”. Someone checks whether rain, travel, overtime or an allowance applies. Then every approved line is typed into payroll.

Add those jobs together and the missing day becomes easier to see.

Here is a simple example for a builder with 50 workers across several sites. It is an illustration, not an industry benchmark.

Weekly task	Example volume	Time used
Collect and sort sheets	50 sheets	45 minutes
Chase missing or late sheets	10 workers at 6 minutes	60 minutes
Check hours and approvals	50 sheets at 3 minutes	150 minutes
Resolve unclear entries	8 queries at 10 minutes	80 minutes
Enter hours into payroll	50 sheets at 4 minutes	200 minutes
Final cross-check	One pay run	45 minutes
Total		580 minutes, or 9 hours 40 minutes

Your numbers may be lower or higher. The point is the mechanism. Paper creates handling at every step, and handling takes time.

Paper makes you enter the same information twice

The worker writes their hours. A supervisor may copy totals onto a summary sheet. Payroll then types the same details into another system.

That is two or three versions of one event.

Every copy creates another chance for a mistake. A 6:30am start becomes 8:30am. A 30-minute break is missed. Saturday hours are entered as ordinary hours. A site code is left blank, so labour lands against the wrong job.

A digital timesheet does not make payroll rules disappear. It does remove the need to read handwriting and re-key approved hours. That is where much of the weekly time goes.

You can see how time capture connects with payroll in the Project Payroll product hub. The timesheet and payroll workflow tour also helps you map the steps that currently sit between site and pay run.

Chasing costs more than data entry

Typing is visible. Chasing is harder to spot.

A missing timesheet can trigger a text, a phone call and a chat with the foreman. If the worker has moved to another site, it may take longer. If payroll closes at noon, the interruption becomes urgent.

Late sheets also create choices nobody wants. Payroll can delay the run, estimate hours or process a correction later. Each option adds work and risk.

The cost is not just payroll’s time. Supervisors stop managing work to answer questions about last Tuesday. Workers check old messages or try to remember when they finished. Project managers investigate whether an extra two hours were approved.

Ten people losing six minutes each is another hour gone across the business.

Construction time is not one simple total

A sheet showing “42 hours” is rarely enough.

Payroll may need the day, start time, finish time, break, site, task and approval. Those details can affect:

• ordinary hours and overtime
• Saturday, Sunday and public holiday rates
• casual loading
• fares, travel and other allowances
• meal allowances after qualifying overtime
• rostered days off
• site costing and client reporting
• superannuation and leave calculations

As at August 2026, a full-time employee covered by the Building and Construction General On-site Award 2020 generally works an average of 38 ordinary hours a week. Exactly when overtime starts can also depend on the employee’s classification, work pattern, award provisions and any applicable enterprise agreement.

As at August 2026, casual employees under that award generally receive a 25 per cent casual loading. If a paper sheet does not clearly identify the worker’s employment type or the hours worked each day, checking the correct treatment takes longer.

A weekly total cannot reliably answer those questions. Payroll needs the detail behind it.

Small errors can flow into several calculations

Suppose a paper sheet understates one worker’s overtime by two hours. The immediate issue is underpaid wages. But the correction may also affect an allowance, job cost, super treatment and payroll reporting.

As at August 2026, the compulsory super guarantee rate is 12 per cent for eligible ordinary time earnings. Super does not apply to every payment in the same way, so the earning type matters as much as the total.

That is why “we will fix it next week” is not always a quick fix. Payroll may need to reverse or adjust entries, check tax and super, issue a corrected pay slip and explain the change to the worker.

The original two-minute timesheet error can become a 20-minute payroll job.

Paper weakens the record behind the pay

A box of timesheets is not automatically a good payroll record.

Sheets can be damaged, lost or filed under the wrong job. Pencil fades. Approval signatures are hard to identify. A total may be altered without showing who changed it or why.

As at August 2026, Australian employers generally need to retain employee time and wage records for 7 years. Those records must be legible, in English and readily accessible to a Fair Work Inspector.

As at August 2026, an employee must generally receive a pay slip within 1 working day of being paid. If payroll is waiting for paper from site, that deadline does not move to suit the paperwork.

Good digital records show the original entry, approval, edit history and payroll result. That gives you a cleaner trail when a worker asks about a payment months later.

How to work out your real weekly cost

Do not start with the price of paper. Start with people’s time.

For one pay cycle, record the minutes spent on:

1. Handing out or printing sheets.
2. Collecting sheets from each site.
3. Chasing missing entries.
4. Checking start, finish and break times.
5. Confirming overtime and allowances.
6. Getting supervisor approval.
7. Entering hours into payroll.
8. Correcting mistakes after entry.
9. Answering worker questions caused by unclear records.

Multiply those hours by the loaded hourly cost of the people doing the work. Include payroll, administration, supervisors and project managers.

For example, eight hours at a loaded cost of $55 an hour is $440 each week. Across 48 pay weeks, that is $21,120. This is only an example. Use your own wage costs and payroll calendar.

Then count corrections. A low volume of costly corrections can matter more than basic entry time.

What a better site process looks like

The practical goal is one approved record of time.

A worker enters time against the right site or job. The supervisor checks it while the week is still fresh. Payroll receives approved hours with the details needed to apply rates and allowances. Changes are recorded rather than rubbed out or written over.

Keep the site process short. Workers should not need to understand every payroll rule. They do need clear fields for starts, finishes, breaks, job codes and common site events.

Supervisors should approve exceptions, not rebuild every timesheet. Payroll should check the result, not type the whole week again.

That is how builders get the missing day back. Not through one big change, but by removing dozens of small handling jobs from every pay run.
