Whether you should outsource your payroll administration or do it yourself depends on three factors: the number of employees, the complexity of your payroll rules (collective labor agreements, variable pay, pension), and the internal knowledge and time you have. Rule of thumb: with few employees and sufficient knowledge, you can manage it perfectly yourself with modern software at lower costs; if your organization grows or complexity increases, outsourcing — or a hybrid middle ground — pays off due to time savings, continuity, and reduced compliance risk. The legal responsibility for correct payroll tax declarations remains with you as the employer in both cases.
There is no universally correct answer to the choice of outsourcing your payroll administration or doing it yourself. The decision hinges on three considerations you must make for your own situation:
Number of employees — the larger your workforce, the more hours processing takes, and the faster outsourcing or robust software pays off.
Complexity — multiple collective labor agreements (CAOs), shift work, variable pay, and special pension schemes increase the risk of errors and the required expertise.
Internal knowledge and time — do you have someone who masters payroll rules AND has the time to keep up with changes? Or does everything rely on one person?It's not an all-or-nothing choice. Besides doing it entirely yourself and fully outsourcing, there is a valid third route: processing it yourself using good payroll software, with external support for complex issues. Further on, we will elaborate on all three scenarios, including indicative prices and a decision tree.
Inzicht
Many comparisons about outsourcing payroll or doing it yourself come from payroll providers themselves and subtly push towards one side. As an independent selection platform, OptioHR weighs both options neutrally — the conclusion that suits you depends on your situation, not on what a vendor sells.
Before you choose, it helps to have a clear understanding of what it all covers. Payroll administration is more than just "transferring wages." It encompasses a chain of legally required, periodic tasks:
Wage calculation — gross-net calculation per employee, including allowances, deductions, holiday pay, and provisions.
Payslips — a correct, readable payslip per employee per period.
Payroll tax declaration to the Tax Authorities — timely declaration of payroll taxes; errors or late declarations lead to additional assessments and fines.
Pension declaration — submission to the pension fund or insurer.
Collective Labor Agreement (CAO) application — applying the correct wage scales, periodic increases, and regulations, and implementing changes immediately.
Annual statements — the annual statement per employee and the year-end closing.Additionally, GDPR (careful handling of personal data) and monitoring changes in laws and regulations play a role. Crucial: the employer remains ultimately responsible for a correct payroll tax declaration, even when outsourcing the work. Outsourcing shifts the execution, not the liability.
Payroll administration is low-frequency visible but high-frequency risky: it goes well monthly, until one missed CAO change or declaration error accumulates.
Doing it yourself means you process payroll internally — usually with payroll software, sometimes still manually. For smaller organizations with the right knowledge, this can be attractive.
Advantages of Doing It Yourself
Direct control and insight — you have real-time visibility into all figures and can immediately act on questions or corrections.
Lower costs with few employees — for a small team, the hours spent and a software license often outweigh the per-employee rates of an external office.
Fast and simple with modern software — contemporary payroll software automates calculations, flags changes, and submits declarations. This significantly lowers the barrier to doing it yourself.The size of this software market underscores how ingrained self-processing has become: monthly, more than 3.4 million Dutch people receive their payslip via the software of a single large provider [1].
Tip
Considering doing it yourself? Then choose software with automatic legal and CAO updates and built-in controls. That is exactly the difference between "doing it yourself" as a risk and as a manageable choice. You can [compare payroll software](/oplossingen/payroll) to see which packages include these updates as standard.
Disadvantages and Risks of Doing It Yourself
Keeping up with laws and regulations — tax rules and CAOs are constantly changing. If you miss a change, you'll fall behind.
Single-person dependency — in small teams, processing often relies on one person. If that person is absent or leaves, payroll administration comes to a halt. This is not a theoretical risk: almost 25% of internal payroll administrators already suffered chronically from understaffing (NIRPA, 2020) [2], and recruiting a senior payroll specialist in the current labor market takes 3 to 6 months [2].
Penalty risk with the Tax Authorities — errors in payroll tax declarations can lead to additional assessments and fines.
Lack of segregation of duties — the four-eyes principle (someone checks another's work) is difficult to organize in small teams, meaning errors remain unnoticed longer.Let op
The cost advantage of doing it yourself is real, but also include the hidden costs: time to keep up knowledge, error correction, and the continuity risk of one key person. These items are rarely in a spreadsheet but often determine the true picture.
When outsourcing, a payroll administration office, accountant, or payroll service provider takes over the processing. You provide changes; they deliver payslips, declarations, and annual statements.
Advantages of Outsourcing
Time savings — you delegate the laborious, periodic tasks to a specialist and free up internal hours for your core activities.
No worries about changing legislation — the office monitors and applies legal and CAO changes.
Continuity through a team — instead of one internal person, a team supports the processing; holidays, illness, or departure do not halt operations.
Specialist knowledge — expertise is readily available for complex situations (multiple CAOs, international payroll rules, special remunerations).
Predictable costs — a per-employee rate makes your costs easy to budget.Disadvantages of Outsourcing
Costs scale with growth — you pay per employee per month, so as you grow, the bill grows (although the per-employee rate usually decreases, see below).
Less direct control — you have less insight into the details and depend on the office's turnaround time for changes and corrections.
Dependency on the provider — the quality of your payroll administration depends on the reliability and accessibility of the party you choose.Inzicht
Understaffing often makes outsourcing more attractive for larger organizations. Companies average one payroll administrator per 1,000 employees [3], while the number of payroll and HR vacancies has increased by 64% compared to before the COVID-19 crisis [3]. Scarce internal capacity strengthens the continuity argument for (partially) outsourcing.
Costs are often the decisive factor. Below are the indicative amounts — note: these are market averages for 2026 that vary per office and situation. Always request a quote based on your number of employees and desired services.
Costs of Outsourcing
Outsourcing is usually charged per payslip or per employee per month:
The market average rate is around €6 to €10 per paid employee per month (excl. VAT) [2].
For a single payslip, you typically pay around €10 (excl. VAT) [4].
For having payslips made, an average of €12.50 per employee per month (incl. VAT) [5] also circulates.
Additionally, expect one-time setup costs starting from approximately €20 per employee [5].The per-employee rate generally decreases as you employ more people — the so-called volume discount. Average indicative prices for 2026 (incl. VAT) [5]:
| Number of employees | Average price per employee per month |
|---|
| 0–25 employees | €10.00 |
| 26–50 employees | €9.00 |
| 51–100 employees | €8.00 |
| 100+ employees | €7.50 |
To get a sense of the absolute amounts: for an organization with
550 employees at €10 per employee per month, it amounts to approximately €79,860 per year (incl. VAT) [2]. At that volume, every euro per employee adds up significantly — a reason to negotiate sharply or consider the hybrid route.
Costs of Doing It Yourself
Doing it yourself has a different cost structure:
Software license — a monthly or annual subscription to payroll software.
Internal hours — the time your employee spends on processing, checking, and declaring.
Hidden costs — error correction, keeping up knowledge, and covering for absences. These items are difficult to budget but real.Cijfer
Good digital HR and payroll processes can yield significant returns: research by Prof. Bram Steijn (Erasmus University) calculated that e-HRM in a company with 1,000 employees can save almost €800,000 and reduce absenteeism by 25% [1]. This illustrates that the software choice itself is a value lever — not just a cost item.

A popular question — but there's no hard limit. The tipping point is less about the number of employees and more about the combination of
knowledge, time, and risk.
1–2 employees with sufficient knowledge — doing it yourself with software is often the most cost-effective.
Growing workforce, increasing complexity — multiple CAOs, shift work, or variable pay increase the time investment AND the risk of errors. Then outsourcing, or doing it yourself with robust software plus support, becomes more attractive.
No internal knowledge or capacity — regardless of the number of employees, outsourcing quickly becomes sensible, as the continuity and penalty risk would otherwise be too great.In short: don't let only the headcount decide. A team of five with a complicated CAO might benefit more from outsourcing than a team of fifteen with a simple payroll structure and an experienced administrator.
Most articles frame the choice as binary. In practice, many SME organizations work with a
hybrid model: you process payroll yourself using modern payroll software, while an external party or accountant oversees complex issues — such as year-end closing, CAO changes, or payroll tax declarations.
This way, you combine the best of both worlds:
Control and lower costs of doing it yourself.
Safety net for compliance and continuity of outsourcing.This route stands or falls with the quality of your software. Packages with automatic legal and CAO updates, built-in controls, and clear alerts reduce the risk that weighs most heavily when doing it yourself. For this, view an overview of the best payroll software in the Netherlands to see which providers score highly on automation and support.
Here you see the three scenarios at a glance:
| Criterion | Do It Yourself | Hybrid (Do It Yourself + Support) | Outsourcing |
|---|
| Costs | Low with few employees | Medium | Scales with the number of employees |
| Internal time investment | High | Average | Low |
| Control and insight | Maximum | High | Limited |
| Compliance risk | Higher (depending on software) | Lower | Low |
| Continuity | Vulnerable (one person) | Reasonably secured | Well secured (team) |
| Required internal knowledge | High | Average | Low |
Go through these six yes/no questions. The more often you answer "no," the stronger outsourcing (or the hybrid route) becomes an option.
Do you have fewer than ~10 employees? If yes, doing it yourself with software often remains affordable.
Is your payroll structure simple (one CAO or no CAO, little variable pay, standard pension)? The simpler, the more feasible doing it yourself.
Do you have internal knowledge of payroll and tax rules? Without that knowledge, the penalty risk increases significantly.
Is there time to keep up with changes in legislation and CAOs? If not, outsourcing or support helps.
Is processing secured by more than one person (segregation of duties, replacement in case of absence)? If not, your continuity risk is high.
Do you expect to grow or become more complex in the coming years? If yes, choose a solution that scales with you.Tip
Do you primarily answer "yes" to questions 1–5 and is growth limited? Then doing it yourself with good software is suitable. Many "no's" or strong growth plans? Then outsourcing or the hybrid route weighs more heavily. Still unsure between providers?

Is it better to outsource payroll or do it yourself?
That depends on three factors: the number of employees, the complexity (CAOs, variable pay, pension schemes), and the available internal knowledge and time. Rule of thumb: with few employees and sufficient knowledge, you can manage it perfectly yourself with modern software at lower costs; if your organization grows, complexity increases, or knowledge is lacking, outsourcing pays off due to time savings, continuity, and reduced compliance risk. The legal responsibility for a correct payroll tax declaration remains with you as the employer in both cases.
What does it cost to outsource payroll administration?
Outsourcing is usually charged per payslip or per employee per month. The market average rate is around €6 to €10 per paid employee per month (excl. VAT) [2], with a single payslip typically costing around €10 (excl. VAT) [4]. Additionally, expect one-time setup costs starting from approximately €20 per employee [5]. The per-employee rate generally decreases as you have more employees (volume discount). Always request a quote based on your number of employees and desired services.
From how many employees does it pay to outsource payroll administration?
There is no hard limit, but the tipping point primarily lies with knowledge, time, and risk — not just numbers. With one or two employees and sufficient knowledge, doing it yourself with software is often the most cost-effective. As your workforce grows and payroll rules become more complex (multiple CAOs, shift work, variable pay), the time investment and error risk increase, making outsourcing — or doing it yourself with robust software plus support — more attractive.
What are the risks if I do payroll administration myself?
The biggest risks are: missing changes in laws and regulations or CAOs, errors in the payroll tax declaration with possible fines from the Tax Authorities, and strong dependency on one person — if that person is absent or leaves, processing comes to a halt. In small teams, segregation of duties (four-eyes principle) is also difficult. Good payroll software with automatic updates and alerts significantly limits these risks.
Can you also partially do payroll administration yourself and partially outsource it?
Yes. Besides doing it entirely yourself or fully outsourcing, there is a hybrid middle ground: you process payroll yourself using modern payroll software (control and lower costs) while an external party or accountant oversees complex issues such as year-end closing, CAO changes, or payroll tax declarations. This way, you maintain control and mitigate compliance and continuity risks.
You now have the pros and cons, the costs, and a decision tree. Here's how to turn it into a choice:
Answer the six decision questions for your situation and determine whether you lean towards doing it yourself, hybrid, or outsourcing.
