Time Tracking via App vs. Paper vs. Excel: What Really Works – and What It Costs

The honest question: Why do businesses switch their time tracking at all?

Most companies don't switch their time tracking because they read an article about it. They switch because something has gone wrong: a regulatory inspection, a wage dispute, an employee claiming their overtime was never recorded – or simply because payroll once again spent hours poring over illegible timesheets.

This article is not marketing. It is an honest comparison of the three most common methods of working-time recording in small and medium-sized businesses: paper, Excel and app. With real figures, concrete weaknesses – and a clear answer to the question of what really suits which business.

Method 1: Time Tracking on Paper

How it works

Timesheets, logbooks, handwritten lists – paper is the oldest and still the most widely used method. Employees enter start, end and break times manually. At the end of the month the sheets are collected, transferred and used for payroll.

Arguments in favour

• No acquisition costs, no software, no IT
• Works without electricity, network and smartphone
• Everyone understands it – regardless of language

Arguments against

• Entries from memory – often days later and inaccurate
• Illegible handwriting, missing signatures, lost sheets
• No proof that entries are correct – legally vulnerable during inspections
• Manual transfer costs 30–60 minutes per employee per month
• No real-time overview for schedulers or payroll
• Archiving 7 years of paper is laborious and error-prone

Legal sticking point: The Working Hours Act requires traceable, audit-proof records. A handwritten timesheet filled in by the employee themselves is barely a reliable piece of evidence in a dispute – neither against the employee nor against an authority.

Method 2: Time Tracking with Excel

How it works

Employees enter their times into an Excel spreadsheet – either themselves by e-mail or via a shared document. Payroll manually calculates supplements and overtime. Many businesses have built their own highly complex Excel solutions over the years.

Arguments in favour

• Cheaper than dedicated software
• Flexibly adaptable to your own processes
• Many people know Excel and feel comfortable with it

Arguments against

• Error-prone: one wrong decimal point, one wrong formula – and the entire monthly payroll is incorrect
• No real-time access: the spreadsheet is only as current as the last e-mail
• Not mobile: employees on the building site or in the field have no practical access
• Version chaos: who has the current file? Were all changes adopted?
• No GPS proof, no timestamp – no added value over paper during inspections
• Excel scales poorly with multiple employees and locations
• Often unusable for international employees without German language skills

The underestimated Excel problem: Many businesses only realise during a payroll audit or an employment law dispute that their Excel records are not recognised as audit-proof evidence – because they can be altered retrospectively and no automatic timestamp exists.

Method 3: Time Tracking via App

How it works

Employees clock in and out via a smartphone app – in real time, with an automatic timestamp, optional GPS proof and direct project assignment. All data is centralised and can be retrieved, evaluated and exported at any time.

Arguments in favour

• Real-time overview: who is currently on duty? Who has not yet clocked in?
• Audit-proof: timestamps are tamper-proof and admissible in court
• GPS proof: where was the employee when clocking in? Documented beyond dispute
• Automatic supplement calculation: night, Sunday and public holiday hours are detected automatically
• Multilingual: employees work in their native language – errors caused by misunderstandings are eliminated
• Offline-capable: clock-ins are saved locally even without a network connection
• Direct payroll export: no more manual transfer
• Scalable: works just as well for 5 employees as for 500

Arguments against

• Monthly licence costs (typically €3–8 per employee)
• Implementation effort – one-off, minimal, but present
• Employees without a smartphone need an alternative (QR code, NFC, terminal)

The direct comparison: Paper vs. Excel vs. App

What does time tracking really cost? The hidden costs of paper and Excel

Many businesses believe paper and Excel cost nothing. That is true at the licence level – but not in reality. The real costs arise elsewhere:

Time costs

A business with 20 employees that spends 4 hours per month consolidating timesheets loses 48 hours of administrative time annually – paid at the salary of an accountant or office manager. At an internal hourly rate of €35, that amounts to €1,680 per year – just for transferring paper.

Error costs

Payroll errors caused by incorrectly recorded supplements, forgotten overtime or misallocated hours cost businesses an average of several hundred euros per employee per year – either as back-payments to the employee or as lost revenue through overpaid wages.

Legal costs

A single employment law dispute over unproven overtime, or a regulatory inspection with missing records, costs more than three years of app licences – for the entire business.

Staff turnover costs

Employees who cannot transparently view their own hours leave sooner. Every unnecessary resignation costs an average of €5,000 to €15,000 in recruiting and onboarding expenses.

Example calculation: A business with 15 employees pays approximately €75–120 per month for Jobilino. If it saves just 3 hours of administrative effort per month and avoids one payroll error per quarter, the investment has paid for itself after the first month.

Which method suits which business?

Paper – only still sensible in these cases

Paper is justifiable for sole traders without employees, or businesses with a maximum of two employees at a fixed location who have no field assignments and whose working hours are the same every day. For everyone else, paper is a liability gap in 2025.

Excel – sensible only as a transitional solution

Excel is acceptable for businesses that are currently digitising and need a short-term bridge. As a long-term solution, Excel is too error-prone and legally too uncertain for any business with more than five employees, field staff or changing work locations.

App – the right solution for these businesses

A time-tracking app is the right choice for all businesses that can answer yes to more than one of the following points:

• � Employees work outside the office or at changing locations
• � The team consists of more than 5 people
• � There are shift, night or weekend duties with supplements
• � Employees speak different native languages
• � The administrative burden of payroll is too high
• � You want to be able to act immediately during a regulatory inspection

Why Jobilino and not another app?

There are many time-tracking apps on the market. Jobilino was developed specifically for businesses with mobile and international teams – and differs in three decisive ways:

• � Genuine multilingualism: Not just the interface – notifications, shift plans, tasks and forms also appear fully in the employee's native language. Romanian, Polish, Slovak, Hungarian, Croatian, Serbian, Turkish, German, English.
• � Offline-first: Jobilino works without a network connection – on building sites, in basements, in remote deployment areas. No other time-tracking system in this price range offers this more consistently.
• � Three recording methods in one app: GPS clock-in, NFC tag and QR code – freely combinable depending on industry and deployment location. No additional hardware budget required.

Conclusion: The right time tracking is not a question of cost – it is a risk decision

Those who use paper or Excel are not saving costs – they are deferring them. Into administrative time, risk of error, legal risk and lost efficiency. The monthly costs of a good app are covered in most businesses within a few weeks through saved effort.

The real question is not: "Can I afford an app?" The question is: "Can I still afford paper and Excel?" For most businesses with more than five employees, field staff or international personnel, the answer is: no.
