CUSTOMER STORY

ABOUT THE COMPANY
Autohaus KAHLE Gruppe is a family-run business with seven locations in the Hanover region. More than 400 employees work in customer service, sales and administration. Around half of the workforce is employed in after-sales services, workshops and parts departments, while approximately 30% work in sales and 20% in administration.
Industry: Retail
Previously, most payroll work was concentrated in the second half of the month. With Personio Payroll, the HR team now records changes as they occur, eliminating duplicate data entry.
The result: Payroll takes just two days instead of four to five, while the number of manual steps has fallen by 50%.
“Personio is like an extra member of the team to me.”

The challenge: Complex payroll requirements and a high manual workload
Payroll at Autohaus KAHLE Gruppe involves a wide range of employment arrangements and pay components. The HR team needs to account for full-time and part-time employees, as well as those in marginal employment, and process basic salaries, bonuses, commissions and other variable payments.
Before introducing Personio Payroll, contract changes and employee data were first recorded internally and then passed on to the external payroll provider via Excel files. This duplicate data entry created additional work and required further coordination.
A heavy payroll workload in the second half of the month
In the second half of each month, the HR team focused heavily on payroll. Most of the processing work took place during this period, regularly tying up significant time and staff capacity.
Although Autohaus KAHLE Gruppe had already reduced the workload with its previous system, payroll still took around four to five days. The company therefore needed a solution that would connect HR and payroll more closely, reduce manual steps and eliminate unnecessary data transfers.
The main challenges:
Duplicate entry of payroll-relevant data
Manual data transfers using Excel files
Different employment arrangements and remuneration models
“We used to enter a lot of data twice. Changes were recorded internally and then passed on to the provider again.”
Leonie Keller|Head of HR
The solution: Simplifying payroll through integrated processes
With Personio Payroll, Autohaus KAHLE Gruppe has connected payroll more closely with its existing HR processes and reduced numerous manual steps. Changes are recorded directly in Personio as they occur – whether it's a salary adjustment, someone joining or leaving the company, or an update to personal details.
At the same time, the HR team can identify payroll discrepancies or missing information early and respond immediately.
Centralised data reduces duplicate work
Employee data, salary information and other payroll-relevant details are stored centrally in Personio. When someone new joins the company, existing data no longer needs to be entered again for payroll or transferred to other systems.
Managers and employees benefit too: They can access a wide range of information themselves, depending on their access rights, without having to contact HR first.
Automation makes everyday tasks easier
Recurring tasks also require less manual work. According to Leonie Keller, examples include certificate management and electronic sick notes (eAU). Existing data can be reused directly rather than having to be retrieved or entered again. During onboarding and offboarding, tasks are also created automatically to ensure that important steps are initiated reliably.
The time savings are substantial: Instead of four to five days, Autohaus KAHLE Gruppe now needs just two days to process payroll. Most of the work is handled by one person. At the same time, Leonie Keller estimates that the number of manual steps has fallen by 50%.
“We have everything in one system. That makes collaboration easier and significantly reduces our workload.”

Looking ahead: More room for strategic HR work
The reduced payroll workload gives the four-person HR team more capacity to focus on strategic tasks. With less time spent on duplicate data entry and manual coordination, the team can devote more time to developing and improving its HR practices.
Autohaus KAHLE Gruppe also uses Personio beyond payroll. With Recruiting, Performance & Development and Surveys, the company uses additional features to connect HR processes across different stages of the employee lifecycle.
“We can work much more strategically and spend significantly less time on operational tasks.”
