When Does Outsourcing Payroll Pay Off for Small Businesses?
Payroll is one of the tasks that every business has to handle reliably and on time. Even small errors can lead to questions from employees, corrections to reports, or extra coordination effort. For small businesses, the question therefore often arises whether payroll should be handled in-house or handed over to a specialized service provider.
This decision affects a large part of the German economy. According to the Federal Statistical Office (Statistisches Bundesamt) on small and medium-sized enterprises, around 3.2 million businesses counted as small and medium-sized enterprises in 2024. That corresponded to 99.3 percent of all businesses. Around 2.7 million of them were considered micro-enterprises. These businesses often lack their own departments dedicated exclusively to personnel administration and payroll.
There is no universal answer, since the right solution depends on the number of employees, the expertise available, and the company’s processes. In many cases, however, outsourcing pays off earlier than founders initially assume.
Why Payroll Is Especially Demanding for Small Businesses
In a small business, management often takes on several tasks at once. Alongside customer service and order processing, there are administrative tasks for which no dedicated specialist department exists. Payroll nevertheless has to be prepared, checked, and completed correctly every month.
It is not enough simply to enter the agreed gross salaries into software. Working hours, pay supplements, absences, one-time payments, benefits in kind, and other special cases can affect payroll. On top of that come legal requirements and reporting obligations that must be taken into account on an ongoing basis.
Payroll is subject to clear formal requirements. This is shown by the Ordinance on Pay Statements (Entgeltbescheinigungsverordnung) published by the Federal Ministry of Labor and Social Affairs (Bundesministerium für Arbeit und Soziales, BMAS). It specifies exactly what information must appear on a pay statement. In addition there are the reporting obligations under social insurance law; among other things, the BMAS explains the basics in connection with the optimized reporting procedure (optimiertes Meldeverfahren).
It becomes especially tricky when the necessary knowledge rests with a single person. If that person is out because of illness or vacation, on-time payroll quickly hangs in the balance. An external service provider reduces exactly this dependency because it works with fixed processes and clear substitution arrangements.
At What Company Size Does Outsourcing Pay Off?
There is no fixed minimum number of employees. Outsourcing can make economic sense even with just a few employees if the business has neither the necessary experience nor enough time in-house. What matters is not the number of employees alone but the actual complexity of payroll.
A business with only five employees can easily cause more work than one with fifteen. Changing working hours, variable pay, mini-jobs (Minijobs), or different contract models push up the monthly effort. With uniform salaries and stable staffing structures, on the other hand, payroll is usually easier to handle in-house.
When deciding, small businesses should consider the following points, among others:
- Time spent on preparation, checking, and follow-up questions
- Costs for software, training, and ongoing updates
- Expertise available in the company
- Dependence on individual people
- Number and complexity of employment relationships
- Effort for data protection and secure data transmission
A mere comparison of the monthly service provider costs therefore falls short. The working time tied up internally also causes costs, even if it does not appear directly on an invoice. If you spend three hours a month on payroll as a founder, you don’t have those three hours for sales.
Even so, a careful comparison is advisable before you decide. An overview of the differences and the respective strengths and limits is offered by the article on outsourcing or in-house payroll.
A quick decision aid
Lean toward doing it in-house if salaries stay largely stable, there are only a few employees with clear contracts, someone on the team really has the skills, and a substitute is available.
Lean toward outsourcing if working hours and pay fluctuate, mini-jobs or mixed contract models are involved, the knowledge depends on a single person, or the time is simply better invested in the core business.
What We See in Our AVGS Start-Up Coaching Sessions
In AVGS start-up coaching, we support people on their way from unemployment into self-employment. Since 2018, this has grown to more than 750 supported projects, including more than 500 start-ups. Two patterns keep coming up, and both feed directly into this question.
First: payroll is treated as a stand-alone topic. In reality, it is tied to the rest of the accounting: receipt organization, liquidity planning, and working with the tax advisor all interlock. In coaching, we build this foundation before the first invoice goes out. Whoever retrofits it later pays extra: for cleanup, for corrections, for time.
Second: the step from solo to employer is not planned. The start-up itself is calculated carefully: financial plan, prices, customer acquisition. The first hire almost always falls by the wayside because it seems two years away. When it then comes up, suddenly there is time pressure, and the decision is made by gut feeling instead of by the numbers.
What we take from this: this question can be settled long before the first hire. And regardless of the decision, responsibility for the data supplied stays in-house. It pays to understand the basics, even if a service provider takes over the execution.
Where do you stand right now?
If you yourself are starting a business from unemployment or are at risk of unemployment, an Activation and Placement Voucher (Aktivierungs- und Vermittlungsgutschein, AVGS) can fully finance the consulting. Whether you get one is decided by the Employment Agency (Agentur für Arbeit) or the Jobcenter. The AVGS for start-up coaching is a discretionary benefit (Ermessensleistung).

Frequently Asked Questions About Outsourced Payroll
What tasks does an external service provider take on?
The exact scope of services depends on the chosen provider and the agreed package. As a rule, the service provider handles the monthly payroll, prepares the payroll documents, and processes the required reports. The company remains responsible for submitting all relevant data, such as working hours, absences, new hires, or salary changes, completely and on time.
How much does outsourcing payroll cost?
The costs usually depend on the number of employees, the scope of services, and the complexity of the employment relationships. Additional effort can arise if corrections, variable pay, or special contract models frequently have to be taken into account. For a meaningful comparison, companies should include not only the service provider’s offer but also internal software costs, training, and their own time.
Does the company remain responsible despite outsourcing?
Even after outsourcing, the company continues to be responsible for the accuracy and completeness of the information provided. That is why clear responsibilities, fixed deadlines, and traceable control processes are required. A reliable service provider supports proper processing but does not replace the internal review of important personnel and payroll data.
Do I already need this as a solo self-employed person?
No. Without employees, there is no payroll. The topic becomes relevant as soon as the first person is hired, or if you regularly work with mini-job employees.
