A project manager at an 80-person IT consultancy is familiar with the scenario: The new time recording system costs 6 euros per user and month, and the rollout will be completed in two weeks. Eighteen months later, rebookings, two external training sessions, a DATEV interface that had to be developed retrospectively, and half a year of admin work add up to an amount that is three times as high as the originally calculated list price.
What is behind it in everyday life
This is not an exceptional case, but a typical pattern. Costs almost always explode in the same places:
- Employees book times inconsistently or too late, managers approve without clear rules and HR corrects.
- Project times are missing or not properly allocated, resulting in queries, post-calculations and late invoices.
- Interfaces are clarified too late, resulting in detours via Excel and monthly duplicate maintenance.
This is exactly where modern systems such as ZEP come in: They connect working time tracking, project times and evaluations in a platform so that companies not only record times, but also really understand their cost structures and manage their projects sustainably.
Why the cheapest tariff can be the most expensive decision
According to market observers, the actual TCO driver For time recording systems, the license price is lower than in terms of set-up, process definition and interface costs. Anyone who only compares the monthly rate is not making an economic decision, but a half-finished one.
Brief reality check for decision makers
If you only compare the price per user today, there are three key control questions missing for implementation:
- Who decides on corrections, approvals and rules in everyday life?
- Which data must be reliably exported at the end of the month and where?
- What two to three mistakes do you make every week today and how should the system prevent them?
Without these answers, you often don't buy time recording, but follow-up costs.
Where the costs really arise in everyday business
The problem doesn't start with the provider, but with internal preparation. There are three classic cost drivers across industries:
Manual fixes: Timesheets and Excel solutions systematically generate errors that must be corrected retroactively. Each adjustment costs working time in payroll accounting, with supervisors and in the affected team.
Missing project funding: In agencies and consultancies without Project time recording Is the data basis for post-calculation missing and invoicing. The result: delayed billing, poor contribution margins, idle benefit. This is exactly where the biggest economic difference between simple time recording and project-oriented systems occurs. Tools such as ZEP make it possible to allocate working hours directly to projects, budgets and services. This automatically results in evaluations of project profitability and the actual profitability of individual customer projects, which enables well-founded project management.
Compliance rework: Since the BAG ruling of 2022 and ongoing legislative processes, the documentation requirement is no longer a grey area. that Federal Ministry of Labour and Social Affairs confirmed: Employers are required to introduce a system for recording working time. Systems that do not meet these requirements will be retrofitted sooner or later, always at the employer's expense.
The 7 cost blocks of time recording: the TCO model
If you want to compare offers objectively, you need a structured model. Seven cost blocks determine the true three-year price.
Cost block 1: Software license
The most obvious post. Standard market price ranges 2025/2026 is around 3 to 12 euros per user and month, depending on the range of functions and provider. Affordable entry-level solutions usually only cover pure stamp times, without project reference or deeper evaluations.
In everyday life, this is what happens here: Employees stamp time, but project allocation absences and approvals continue via side roads.
Typical effect: You pay for a license, but HR and team leads pay extra with follow-up and inquiries.
Here's how to solve it pragmatically:
- Define three mandatory functions before concluding a contract, such as project reference, approval, export.
- Test two real daily routines, a normal day and a day with absenteeism or overtime.
- Name a responsible person to run through the monthly financial statements process once in the system.
Cost block 2: Hardware and terminal
Depending on the technology (RFID, fingerprint, PIN), stationary terminals for shift operations cost between 300 and over 2,000 euros per device. RFID chips or cards cost a few euros each, but with 120 employees, they quickly cost 500 to 800 euros for the access material alone. There is also assembly, network connection and any replacement devices.
In everyday life, this is what happens here: Shift changes, breaks, changes of location and representatives lead to unclear times when there is no robust recording at the entrance.
Typical effect: Corrections end up with HR and payroll, employees discuss, managers sign based on feeling.
Here's how to solve it pragmatically:
- Plan terminal locations according to routes, not according to IT requirements.
- Define a clear rule for cases of forgetting, including the person responsible and deadline.
- Carry out a test week with real shift staffing, only then roll it out.
Cost block 3: Introduction and configuration
Setup, data migration, adjustment of roles and rights, and the definition of Working time models are often not shown in the offer. A realistic figure for medium-sized companies is 5 to 20 person-days of internal expenditure plus possible external consulting costs.
In everyday life, this is what happens here: Roles and rules are not fixed, which creates exceptions. Exceptions lead to additional bookings. Rebookings create permanent stress.
Typical effect: Admin work is growing because every special rule is solved manually.
Here's how to solve it pragmatically:
- Standardize working time models before you configure. Better three models clean than ten and a half.
- Simplify approval processes, for example only Teamlead approval and HR correction only for exceptions.
- Start data migration small, first master data, then projects, then history only when necessary.
Cost block 4: Training and change management
Every new software changes habits. With 50 employees who work with the system on a daily basis, a structured introduction is not an option, but a basic requirement for acceptance. Expect at least one training session plus documentation that must be maintained internally.
In everyday life, this is what happens here: Employees quickly experience time recording as a control, team leads as an additional task, HR as a complaint center.
Typical effect: Resistance is not shown in meetings, but in forgotten bookings and silent refusals.
Here's how to solve it pragmatically:
- Focus communication on protection: clear overtime, clear breaks, clear billing.
- Conduct role-based training: 30 minutes for employees, 30 minutes for team leads, 30 minutes for HR and admin.
- Offer daily mini-help for a week, such as a fixed slot for questions. The operation then stabilizes.
Cost block 5: Interfaces and integration
DATEV, Lexware, ERP systems, payroll: Where data is manually transferred from one software to the next, there is permanent maintenance costs. A cleanly implemented interface costs once, a missing one costs every month.
In everyday life, this is what happens here: The monthly financial statements become an Excel ritual because export, import or format do not fit.
Typical effect: Double maintenance, inquiries and late payroll processing, month after month.
Here's how to solve it pragmatically:
- Define target system: What is the system of record for pay and what kind of projects.
- Make a real export run in the pilot month, including corrections and re-import if necessary.
- Define responsibility: One person is responsible for the monthly closing process from A to Z.
Cost block 6: Compliance costs
Systems that do not offer audit-proof documentation, immutable time stamps or no export function for operational audits create compliance gaps. Rework during audits, attorney fees and potential fines are real consequences of a system that is too weak.
In everyday life, this is what happens here: Times are added without it being clear what was changed, when and by whom.
Typical effect: During audits, the data basis becomes a risk because there is no traceability.
Here's how to solve it pragmatically:
- Define audit log and change history as mandatory criteria.
- Test exportability before you roll out, not afterwards.
- Appoint a responsible person to carry out a brief compliance check on a monthly basis, for example random checks for additions.
Cost block 7: Failure costs during operation
Manual time recording without structured approval workflows systematically produces errors: incorrect hours, missing absences, unbooked overtime. Comparative analyses show that these hidden process costs for non-digital solutions are permanently higher than the licensing costs of professional software.
The three most common mistakes and how to fix them
- Forgotten breaks or incorrect break lengths: Solution using clear break rules plus reminder logic and approval in case of discrepancies.
- Wrong project reference: Solution based on mandatory selection and a clean project structure, as few projects as possible, but as many as necessary.
- Rebookings at the end of the month: Solution via weekly mini-control by team leads, ten minutes are enough, instead of chaos at the end of the month.
In practice, this difference is particularly evident in modular solutions such as ZEP. For example, companies can start here with a pure time recording tariff and later features such as Project controlling or add evaluations without having to change the system. Details of the tariff levels can be found here.
Implementation in everyday business life: The 10-day plan without chaos
Objective: You introduce time recording in such a way that it is not annoying, does not escalate and does not become a permanent project.
- Day 1 to 2: Define working time models, break rules, absences and overtime rules in writing. One page is enough.
- Day 3: Define roles and approvals. Who can correct, who approves, who sees which evaluation.
- Day 4 to 5: Start pilot group. One team, two projects, a real monthly test run.
- Day 6: Export and interface testing. Complete once, including DATEV or wage export.
- Day 7: Keep training short. 30 minutes of live plus one pager for employees and one pager for team leads.
- Day 8 to 10: Rollout and initial evaluation. Focus on three common mistakes and how they can be prevented in the future.
Time recording without monthly costs: When is the purchase really worthwhile?
The argument sounds convincing: buy once, no ongoing fees. In practice, this logic only applies under specific conditions.
When a purchase license makes sense
A shift operation with a stable number of employees, its own IT department and a system that has been in use for years can benefit from a purchase license. The requirements: internal resources for updates and maintenance are available, the system does not need to be scaled frequently, and the legal situation does not change so quickly that regular functional updates are necessary.
Risk warning that is often forgotten in practice
If updates, adjustments or exports do become necessary later, it not only becomes more expensive, but also more organizationally risky. Changes then happen under time pressure, often in parallel with payroll and project completion. This is exactly where it escalates in everyday working life.
When subscription is the more economical choice
If a company grows, work models change (home office, field service, project work) or if legal requirements become stricter, a subscription with continuous updates is the more predictable option. The decisive advantage: Compliance-relevant functions are maintained by the provider without binding internal development capacity.
The break-even logic is simple: If the internal maintenance costs of a purchase license exceed the subscription fees over three years, the subscription is cheaper. With 100 employees and a subscription price of 6 euros per user and month, the total subscription rate is 21,600 euros over three years. If an IT employee spends one day per quarter on system maintenance, that quickly adds up to a comparable figure.
Electronic time recording costs: realistically calculate terminal, chips, operation
For shift work and production environments, the terminal is often the only practical solution. Apps are excluded when employees are not allowed or do not want to use a smartphone, and when protection against manipulation is a requirement.
How much does a terminal setup really cost
A medium-sized production company with 120 employees at two locations realistically calculates:
Two mid-price terminals: approx. 1,400 to 2,400 euros. There are also 120 RFID chips or cards, assembly and network configuration. Total: 2,500 to 4,000 euros as a one-time investment.
On the other hand, there is the effort that manual timesheets permanently cause: corrections, queries, payroll post-processing. If two clerks each spend one hour a week correcting time, that's almost 300 working hours over three years that produce nothing.
In most shift operations, the terminal investment pays off within 12 to 18 months when combined with software that automatically evaluates and exports.
Mobile time recording costs: app, admin effort, offline scenarios
For IT service providers, consultants and field service teams, the app is the obvious solution. But here too, there are costs that do not appear in the initial offer.
Hidden cost sources for mobile time recording
Device management: When employees use private devices (BYOD), questions arise about data protection, GDPR-compliant processing, and security standards. When company equipment is provided, the purchase price is added.
Offline scenarios: Sales representatives without a stable mobile network need a solution that stores and synchronizes locally as soon as there is a connection. Not every app solution reliably supports this.
Admin effort: Roles, rights, approval workflows, and evaluations must be configured and maintained. Especially with project-based time recording, where every employee allocates time to different projects, there is structured maintenance effort.
This makes mobile time recording neither annoying nor risky
- Decide consciously whether BYOD is allowed. If so, define minimalistic rules, for example only time data, no location data, clear deletion routines when changing devices.
- Make sure that offline use is tested in the pilot, including synchronization and conflict cases.
- Set up approvals in such a way that employees are not constantly blocked, but team leads have a brief overview on a weekly basis.
With the ZEP app Capture Project-related periods also mobile and automatically synchronize them in evaluations. This eliminates the typical aftercare in Excel, which costs several hours per month in many companies.
Sample calculations: 25, 100 and 300 employees over 3 years
Table: Three scenarios in direct cost comparison over 3 years
Scenario 1: IT service provider, 25 employees (hybrid/remote)
Requirement: Mobile time recording with project reference, DATEV export.
Subscription version (6 euros/user/month): 5,400 euros license costs over 3 years. Internal implementation costs: approx. 3 person days. Interface to DATEV: included in the tariff or around 200 to 500 euros once. Total range: 6,000 to 7,500 euros over 3 years.
Without a digital solution: time sheets, manual Excel maintenance, delayed project billing. If a project manager invests two hours a week for time corrections and invoice preparation, that is around 310 working hours over three years or, at an internal hourly billing rate of 80 euros, 24,800 euros in fixed working time.
Scenario 2: Production, 100 employees (shift work)
Requirements: Terminal, RFID, central evaluation, wage export.
Hardware costs: 2 terminals, chips for 100 mA: approx. 2,500 to 4,000 euros. Subscription software: 4 euros/user/month for shift work rate: 14,400 euros over 3 years. Training: 2 days in-house. Total range: 18,000 to 22,000 euros over 3 years.
Manual alternative: 2 administrative staff 3 hours per week for time sheet processing, corrections and payroll processing: approx. 940 hours over 3 years. With an internal cost rate of 45 euros/hour: 42,300 euros.
Scenario 3: agency/consultancy, 300 employees
Requirement: Project time recording, controlling integration, billing.
Subscription (8 euros/user/month, professional features): 86,400 euros over 3 years. Introduction, training, interfaces: approx. 15,000 to 25,000 euros. Total range: approx. 100,000 to 115,000 euros.
What justifies this: With 60 to 80 ongoing projects per year and an average project size of 50,000 euros in turnover, clean project time recording measurably reduces the proportion of uncheap or unbilled services. Even 2% less depreciation equates to 60,000 to 80,000 euros over 3 years at this volume.
Checklist: How to compare offers without cost traps
Before you sign an offer, you should answer the following questions:
About the software:Are future updates included in the subscription or will they be charged extra? Are there functional levels that you will have to buy back at a high price later? Does the system support all working time models that are relevant today and in two years?
For integration:Which interfaces are included in the standard tariff, and which cost extra? How complex is data migration from the previous system?
For compliance:Does the system meet the requirements of current working time tracking law? Are timestamps stored invariably? Is there an audit-proof export for audits?
To scale:How do costs develop if you have 20% more employees? Are there minimum contract terms or volume discounts?
For support:How quickly does the provider respond to technical problems? Is support available in German and is it included in the tariff?
Additional check for less stress in everyday life:
- Is there a weekly routine that reduces rebookings, such as a brief Teamlead check?
- Is it clear how exceptions are resolved, such as forgotten bookings, business trips, shift exchanges?
- Is it defined who is responsible for the closing process at the end of the month and who only delivers?
Conclusion: Calculate before you decide
The list price is the worst decision parameter for a time recording system. Anyone who knows all seven cost blocks, who objectively compares terminal against app, purchase against subscription and manual effort against software costs, makes an economically sound decision.
For most SMEs in the DACH region with hybrid teams, project billing or shift operation, a professional solution pays off in the first year if implemented correctly. that ZEP pricing model is modular: You only pay for the features you actually need and scale as the company grows.
A concrete next step: Compare your current manual effort in hours per week with your current license costs. The difference reveals how expensive time tracking without a system really is. Tools like ZEP demonstrate that time tracking today can be much more than just a documentation requirement. It becomes a management tool for projects, resources, and profitability.
FAQs
How much does a time recording system cost per employee and month, and what are the additional costs?
Market prices in 2025/2026 are between 3 and 12 euros per user and month, depending on the range of functions and provider. There are also setup costs, internal implementation costs, any hardware costs (terminal, RFID chips) and interfaces to payroll or ERP systems, which are often not included in the base price.
ZEP offers three modular price levels:
- ZEP Clock For pure recording of working time: from 2 euros per user and month
- ZEP Compact With Project Time Recording and Project Controlling: From 7 euros per user and month
- ZEP Professional for comprehensive professional services automation and project operating system: from 18 euros per user and month
Is time recording without monthly costs really worthwhile, or is a subscription cheaper in the long term?
A purchase license is only worthwhile if the company has its own IT capacities for maintenance and updates and the number of employees remains stable. For growing teams, changing work models or new legal requirements, a subscription with ongoing updates is more economically predictable and often cheaper as internal maintenance costs are included.
What are the costs of mobile time recording via app, including offline use and admin work?
App-based time recording is cheaper than terminal solutions, but creates its own cost points: device management (BYOD vs. company devices), GDPR-compliant setup, admin costs for roles and rights, and training. Offline functionality is not self-evident and should be explicitly included in the catalog of requirements.
ZEP offers mobile apps that are already included in every license. So a stationary terminal Can be rented for 15 euros per month.
What are the total costs of time recording over 3 years (software, implementation, training, support)?
For a company with 100 employees, the realistic three-year costs range between 18,000 and 30,000 euros, depending on the model, when hardware, implementation, training and interfaces are included. On the other hand, there are often 30,000 to 45,000 euros in process costs due to manual time recording, which are often not visible in the status quo.
In an example with ZEP Compact (from 7 euros per user) Are there pure license costs of around 100 employees 25,200 euros over three years.
How much does a time recording terminal (RFID/fingerprint) cost, including cards and operation?
Depending on the technology, terminals cost between 300 and over 2,000 euros per device. RFID cards or chips cost a few euros per piece. With 120 employees and two terminals, one-time investments are realistically 2,500 to 4,500 euros. The payback compared to manual timesheet processes often occurs within 12 to 18 months in shift work.
At ZEP terminal Is another approach possible: The terminal can for 15 euros Can be rented monthlyInstead of buying it once. This does not result in a high initial investment, but a predictable monthly hardware cost structure.
At what size of team do Excel and Timesheets become economically unprofitable?
There is no universal limit, but practice shows: From around 15 to 20 employees with project-based billing or variable working time models, manual administration costs exceed the costs of a simple software solution. This limit may be even earlier in the case of shift work involving high correction costs.
