Everyday life today:
- Work hours are recorded on scraps of paper, in Excel, or not at all

Frequently Asked Questions
Here you’ll find answers to the most important questions. If you need further assistance, please feel free to contact our support team.
Is Personizer suitable for tax advisors and law firms?
Yes. Personizer is ideal for law firms with 10 to 200 employees that want to track working hours in compliance with legal requirements, plan vacation time digitally, and manage personnel data centrally. Modules can be purchased individually, so you only pay for what your firm actually uses.
How does the DATEV integration work for law firms?
Personizer supports DATEV’s payroll exchange, payroll import, and payroll export data services. Master data and absence data can be transferred directly into payroll processing without manual export and without a change in data format. The eAU retrieval is also handled through DATEV.
Can I track client hours using Personizer?
Yes, time labels allow you to assign and analyze working hours to clients or internal tasks. This lets you see internally where expenses are incurred. Personizer does not offer billable client billing with invoicing; specialized law firm billing tools are better suited for that.
How much does Personizer cost for a tax firm?
Personizer charges per employee per month. The personnel file starts at €1.00, the vacation planner at €3.00, and the time tracking feature at €3.70. There is no base fee, no minimum contract term for monthly subscriptions, and discounts are available for annual (10%) or two-year (30%) contracts.
How quickly can Personizer be set up and used at the law firm?
In no time at all. You create an account, invite your team, and can get started right away. Time tracking, vacation planning, and employee records are available immediately—no training is required.
Is time tracking with Personizer legally compliant?
Yes. Personizer records working hours in compliance with the law, automatically deducts breaks, and issues warnings in the event of violations of the Working Hours Act. This meets the requirements set forth in the case law of the European Court of Justice (ECJ) and the Federal Labor Court (BAG) regarding the recording of working hours.
Is Personizer GDPR-compliant?
Yes. Personizer is operated by a German company, and all data is stored on ISO-certified servers in Germany. Data processing is fully GDPR-compliant, a point that is particularly relevant for law firms and their clients.
Can I sign up for individual modules?
Yes. Time tracking, vacation scheduling, and personnel files can be purchased separately. You only pay for what your law firm actually uses, with no base fee and no requirement to purchase a package.
