Timesheets do not cost money where they are filled in. They cost money in the office: deciphering, asking back, retyping and correcting whenever a number does not match the roster. So anyone calculating the switch to digital time tracking should not count the two minutes on site, but the whole path from the sheet to the finished payroll run.

What a timesheet really costs

A worked example: assume around six minutes per employee per working day – for filling in and handing over the sheet as well as for the follow-up work in the office. At twenty working days and a notional hourly rate of 30 euros that is about 60 euros per employee per month. With 25 employees that is roughly 1,500 euros a month that nobody sees as a cost item, because it is spread across many small steps.

On top of that comes what cannot be measured in minutes: project hours nobody can assign any more. Overtime that only surfaces when someone leaves. And the customer invoice that goes out a week late because three sheets are missing.

Why Excel only postpones the problem

Excel is the most common first step – and the one that survives longest despite not holding up. The typical limits show after a few months:

  • There is no version history. Who changed which figure and when cannot be reconstructed – exactly what matters in a dispute.
  • It gets filled in retrospectively. Friday afternoon for the whole week, from memory. That is not a record, it is an estimate.
  • It is no use out on site. Nobody opens a spreadsheet on scaffolding or in a stairwell.
  • Evaluation is manual. Premiums, project hours and overtime come out of formulas maintained by one person – and checked by nobody.

What has changed legally

The pressure no longer comes from administration alone. In 2019 the Court of Justice of the European Union ruled (C-55/18) that employers must set up an objective, reliable and accessible system for recording daily working time, and national courts and legislators have been following up since. What that means in one country, Germany, is summarised on our page about the recording obligation. What counts day to day is this: an Excel list compiled after the fact serves the purpose less well than a record created at the time of the work.

What digital recording actually changes

Time is recorded where the work happens: via the app on a smartphone, via an NFC tag on site, at a terminal for employees without a work phone, or in the browser. All routes write into the same data set. The difference from a paper sheet is less about technology than about timing: the hour is created when it is worked, not when somebody remembers it.

In the office the entire recording step therefore disappears. What remains is checking – and that becomes targeted, because the system shows where something is off: an entry still running, a request awaiting approval, a public holiday configured for the wrong country.

The switch takes a week, not a quarter

This order has proven itself: in week one, one crew or team starts – not the whole company. The paper sheets keep running in parallel so nobody is left without a fallback. At the end of the week you compare the two. If the numbers match, the remaining teams follow; if they differ, you can see immediately why – usually a missing site assignment, rarely the app.

The second step is the more important one: define how a forgotten clock-in gets added later. Who may correct it, who approves it, and does the change remain visible? Businesses that settle this in advance have clean data after four weeks. Businesses that leave it open have paper sheets again after four weeks.

Why rollouts fail

  • The whole company starts at once, so one problem hits everybody immediately
  • Employees hear about it on the day it starts
  • There is no rule for late entries, so a parallel route via WhatsApp appears
  • The foreman clocks in for everybody without anyone having authorised it
  • Nobody checked in advance which format payroll actually needs

For trades, cleaning, field service, logistics, production and facility management the digital route is the normal case today. If you still work with Excel, you can run the comparison yourself in a week: the alternative to Excel time tracking can be tested free of charge for 14 days – no credit card and no minimum term.
