Absence Management Software Comparison – The Best Tools

Absence management software helps companies handle holiday requests, sick days and other types of leave digitally, in compliance with GDPR, and without additional administrative burden. Well-known solutions such as Personio, Factorial, Kenjo and Absence.io differ significantly in terms of features, integration capabilities and price. The right tool depends on company size, budget and existing HR systems.

What Is Absence Management Software?

Absence management software is a digital system for recording, approving and analysing all employee absences. It replaces paper-based leave forms and error-prone spreadsheets with an automated, transparent process.

Typical types of absence covered by these tools include annual leave, sick leave, special leave, parental leave, remote working days and training. Many solutions today form part of a broader HR software suite, but can also be used as standalone applications.

Absence Management vs. Time Tracking: What's the Difference?

The two terms are often confused or used interchangeably. The distinction matters: absence management plans and approves leave – periods when employees are not working. Time tracking, on the other hand, records actual hours worked (clock-in and clock-out). Many modern tools combine both functions in a single application. Since the Federal Labour Court (Bundesarbeitsgericht, BAG) ruling of September 2022 (case ref. 1 ABR 22/21), there is effectively a legal obligation in Germany to systematically record working hours – a further argument for using an integrated solution.

What Features Should Good Software Offer?

Essential Features (Must-Have)

A solid absence management software must include at least the following:

• Digital request and approval workflow: Employees submit leave requests digitally; managers approve or decline with a single click.
• Team and department calendar: An at-a-glance overview of all absences – prevents staffing bottlenecks.
• Automatic remaining leave calculation: The system automatically calculates remaining holiday entitlements, including statutory minimums.
• Multiple absence types: Mapping of all absence categories (annual leave, sick leave, parental leave, training, etc.).
• GDPR-compliant data storage: Employee data must be stored securely and in a legally compliant manner (see the GDPR section below).
• Mobile accessibility: A mobile app or responsive web interface is now standard – especially important for teams with mobile employees.

Advanced Features (Nice-to-Have)

Depending on company size and requirements, the following additional features may be relevant: automated notifications and reminders, shift planning, reporting and absence analytics, multi-level approval workflows, and self-service portals for employees.

Integration Capabilities

Absence management software rarely works in isolation. Key integrations include payroll systems (e.g. DATEV, Sage Payroll), time tracking tools, applicant tracking systems (ATS) and communication platforms such as Slack or Microsoft Teams. The better the integration capability, the fewer duplicate entries and manual transfers are required.

How to Choose the Right Software

Checklist: Decision Criteria

Before making a decision, you should be able to clearly answer the following questions:

• How many employees will use the tool?
• Which types of absence need to be covered?
• Which existing HR systems need to be integrated?
• What is the monthly budget per employee?
• Is a provider with EU-based servers required for GDPR purposes?
• Is a mobile app necessary?
• How tech-savvy are the future users?

Choosing by Company Size

For small teams of up to 20 people, a freemium tool such as Absence.io or Calamari is often sufficient. For growing SMEs (20–200 employees), a scalable solution like Factorial or Kenjo is recommended – one that grows with the company. Mid-sized companies and enterprises benefit from all-in-one suites such as Personio or HiBob, which cover not only absences but also recruiting, onboarding and payroll.

Red Flags When Buying Software

Watch out for these warning signs when comparing providers: unclear information about server location (EU or not?), no option to sign a Data Processing Agreement (DPA), no free trial or demo, non-transparent pricing with hidden setup costs, and absent or only non-native-language support for your target market.

GDPR and Data Protection in Absence Management Software

Employee data – particularly sick days – are personal data within the meaning of the General Data Protection Regulation (GDPR, Regulation (EU) 2016/679). This has concrete implications for software selection:

Data Processing Agreement (DPA): When an external company (the software provider) processes personal data on your behalf, a DPA is legally required. Reputable providers make this agreement available as standard.

Server location: Data must be stored within the EU/EEA, or the provider must demonstrate an adequate level of data protection (e.g. through EU Standard Contractual Clauses). Verify this directly with the provider.

Particularly sensitive data: Sick days are classified as health data and are subject to special protection under Art. 9 GDPR. Ensure that only authorised individuals (e.g. direct line managers and HR) have access to this data.

Works council involvement: If your company has a works council (Betriebsrat), it has co-determination rights regarding the introduction of employee monitoring software under §87(1)(6) of the Works Constitution Act (BetrVG). Involve them at an early stage.

Frequently Asked Questions About Absence Management Software

What is absence management software?

Absence management software is a digital tool for managing all employee absences: holiday requests, sick days, special leave and more. It automates the approval process, calculates remaining leave entitlements and creates transparency within the team – replacing manual spreadsheets and paper-based processes.

Which absence management software is best for SMEs?

There is no universal recommendation. Factorial, Kenjo and Absence.io are particularly well-suited for SMEs due to their ease of use, moderate pricing and strong GDPR compliance. The best decision is made after a free trial, during which you can assess usability for your specific team.

Is there free absence management software?

Yes. Absence.io and Calamari offer freemium models that may be sufficient for very small teams. Free versions are typically limited in terms of user count or feature set. For growing companies, it is advisable to switch to a scalable paid solution sooner rather than later.

Does absence management software need to be GDPR-compliant?

Yes – without exception. Employee data (especially health-related data such as sick days) constitutes personal data under the GDPR. You must have a Data Processing Agreement (DPA) in place with the provider and should verify the server location (EU/EEA).

How much does absence management software cost?

Most SaaS solutions cost between €2 and €10 per employee per month. Entry-level plans start at around €2.50 (e.g. Absence.io); mid-range solutions such as Factorial or Kenjo typically cost €4–7. All-in-one suites like Personio are generally priced on request. Also be aware of any setup costs and minimum contract terms.

What is the difference between absence management and time tracking?

Absence management handles planned and unplanned absences (holiday, sick leave). Time tracking records actual hours worked. Many modern tools cover both. Since the BAG ruling of September 2022, there is effectively a legal obligation in Germany to systematically record working hours.

How do I implement absence management software in my company?

A structured rollout typically follows six steps: define requirements (features, budget, number of users), compare providers and use trial access, involve the works council (if applicable), complete the GDPR review and sign the DPA, set up and train a pilot group, then roll out to all employees.

Can absence management software be connected to other HR tools?

Yes – good solutions offer interfaces to payroll systems (e.g. DATEV), time tracking tools and ATS platforms. Before purchasing, verify that the provider supports the integrations relevant to your company.

Conclusion

Absence management software delivers a clear efficiency gain over manual processes for companies with a team size of around ten or more. The choice of the right tool comes down to three key factors: company size, budget and existing IT infrastructure. For SMEs, lean solutions such as Absence.io, Factorial or Kenjo are a good starting point. Mid-market companies benefit from integrated HR suites. Regardless of the provider: GDPR compliance, a valid DPA and an EU server location are not optional – they are mandatory.

Beyond absence management, it is worth looking at further steps in HR digitalisation – including the hiring process. The Aivy platform helps companies assess candidates using scientifically validated, fair methods. Learn more about objective talent assessment with Aivy
