Payroll outsourcing of the payroll department - what is it and why is it worth it?

In the face of constantly changing tax regulations, such as rules on tax-deductible costs or split payment mechanisms, payroll management is becoming one of the most demanding processes in a company. For many businesses, maintaining extensive in-house HR departments is cost-inefficient. A solution gaining popularity in 2026 is payroll outsourcing, that is, professional HR and payroll services provided by an external partner.

Payroll outsourcing – definition and key principles

Let's start by explaining what lies behind this concept. Payroll outsourcing is the transfer of responsibility for calculating salaries, preparing payrolls, and handling settlements with state authorities to an external entity. In a broader sense, we are talking about a service known as HR and payroll outsourcing, which also includes maintaining personnel files, monitoring deadlines for medical examinations, and occupational health and safety (OHS) training.

For a company using this service, it primarily means transferring legal and operational risk to experts who continuously track changes in labor law and personal income tax (PIT) legislation.

Comprehensive HR and payroll services – scope of services

When deciding on HR and payroll outsourcing, an entrepreneur must precisely define their needs. Professional HR and payroll services adjust the scope of their activities to the specifics of a given industry. As standard, they include:

• Salary calculation: preparing payrolls taking into account bonuses, overtime, sick pay, and leave.

• Settlements with ZUS and the tax office: timely preparation and submission of declarations (e.g., PIT-4R, PIT-11, DRA declarations).

• HR administration: maintaining complete employee documentation, recording working time, and managing leave.

• Reporting: preparing cost summaries that help management with budget planning and working capital analysis.

• Advisory: support in interpreting labor law regulations.

At Gremi Personal, we go a step further, combining process outsourcing with in-depth knowledge of the specifics of employing foreigners, which in today's market reality is key to maintaining continuity of production and services.

HR and payroll outsourcing – pricing and factors affecting costs

One of the most frequently asked questions by entrepreneurs is: how much does it cost? If you type "HR and payroll services pricing" or "HR and payroll outsourcing pricing" into a search engine, you should know that the final amount depends on several variables:

• Number of employees: most agencies apply a rate per "pay slip," that is, a fixed fee for each person processed.

• Form of employment: servicing employees on an employment contract differs from processing civil-law contracts (mandate contracts, contracts for specific work) or B2B contracts.

• Employee turnover: in industries with high employment dynamics, costs may be higher due to the need to frequently prepare onboarding documentation and deregister employees.

• Additional services: representation during inspections by the PIP (National Labor Inspectorate) or ZUS, preparing earnings certificates, or handling PPK (Employee Capital Plans).

Although at first glance this investment seems like an expense, in reality payroll outsourcing generates savings. The company does not have to invest in expensive HR and payroll software, training for internal employees, or bear the costs associated with their potential errors.

Why choose outsourcing instead of an in-house department?

1. Security and confidentiality

Transferring payroll data externally minimizes the risk of leaking salary information within the organization, which is often a source of conflict. Moreover, the external company takes on financial responsibility for any errors in settlements with the tax authorities.

2. Continuity of processes

An in-house HR department is prone to "bottlenecks" – the illness or leave of the sole HR specialist can paralyze payments. In the outsourcing model, the service is provided continuously, regardless of the staffing situation at the agency.

3. Scalability

If your company plans rapid growth in employment, HR and payroll outsourcing will allow you to handle this process without the need to immediately hire new payroll specialists. A partner like Gremi Personal flexibly adjusts resources to your needs.

4. Access to modern technologies

By using professional services, you gain access to e-personnel files, online employee portals, and automated settlement systems, which aligns with the business digitalization trend of 2026.

What to choose?

Choosing the right personnel management model is a strategic decision. Payroll outsourcing is not only a convenience but, above all, a way to optimize operating costs and focus on the "core business." Professional HR and payroll services help avoid penalties for errors in settlements and give employees a sense of stability through timely and reliable payments.
