Payroll: the pros and cons honestly explained

Payrolling sounds appealing: someone else handles the admin, and you focus on your business. But is it really that simple? And what are the pitfalls no one talks about?

In this article, we give you an honest overview of the advantages and drawbacks of payrolling. No sales talk, just the information you need to make a sound decision.

What exactly is payrolling?

Let's cover the basics. With payrolling, you outsource legal employer responsibilities to an external party. The employee joins the payroll company's books but works exclusively for your organisation. You select, schedule and manage them. The payroll company handles contracts, wages, NSSO (National Social Security Office) and all the admin.

The advantages of payrolling

Let's start with why so many Belgian employers choose payroll.

You don't have to worry about a thing

This is the main reason. No Dimona (immediate employment declaration) filings, no NSSO calculations, no payslips, no end-of-year bonus puzzles. You pass on the hours worked and receive an invoice. Done.

For many business owners, this is worth its weight in gold. Especially if you don't have an HR department and would rather spend your time on clients than on admin.

The risks sit elsewhere

Is your employee off sick? The payroll company pays the guaranteed salary (during illness). Need to let someone go? They calculate the severance pay and handle the procedure. A legal dispute? That's their problem too.

In our experience with thousands of temporary workers, we see that for many employers this is the deciding factor. The uncertainty is gone.

Flexibility without the hassle

You can scale up quickly during busy periods and scale back down when things calm down. No long notice periods, no difficult conversations. The payroll company takes care of everything.

You choose who works for you

Unlike with a temp agency, you pick the candidate. You conduct the interviews and make the decision. The payroll company then hires the person you chose.

Predictable costs

You pay a fixed amount per hour or per month. No surprises with back-charges, holiday pay or end-of-year bonuses. It's all built into the factor.

The drawbacks of payrolling

Now for the honest part, because payrolling isn't the best choice for everyone.

It costs more than paying wages yourself

Let's not beat around the bush. Payrolling is 2 to 4 percent more expensive than handling the payroll administration yourself. Some sources even mention a 20 to 35 percent surcharge on the gross salary, depending on everything that's included in the factor.

Is that a problem? It depends on your situation. If you have one permanent employee who stays for 30 years, payroll is expensive. If you have twenty flexible workers coming and going, the hours you save often outweigh the extra cost.

Less of a direct bond with your team

Legally, the employee isn't yours. Some employers find that awkward. The worker knows they're officially employed elsewhere, even though they show up at your workplace every day.

In practice, this often matters less than you'd think. When someone is on your work floor day in and day out, they feel part of your team. But it's something to keep in mind, especially for long-term arrangements.

No replacement when someone is sick

Unlike a temp agency, a payroll company doesn't arrange a replacement when your employee falls ill. They do handle the administrative side (the sick note, the guaranteed salary), but operationally you're on your own.

You depend on your payroll partner

Are they slow? Then payslips go out late. Do they make mistakes in the NSSO declaration? Then the problems land on you. The quality of your payroll partner partly determines how smoothly everything runs.

After more than 15 years in Belgian payroll, we know this is one of the most important choices you'll make. A good partner is worth its weight in gold. A bad one costs you money, time and sleep.

Less grip on the details

You hand over control. Some employers are perfectly fine with that; others want to know exactly what's going on. With payroll, you trust your partner to get it right.

When does payrolling make sense?

Payrolling works best in these situations:

• You regularly have changing staff (seasonal work, projects, events)
• You have no HR department or time for admin
• You want to "test" someone before hiring them permanently
• You value peace of mind over the lowest price

Do you specifically work with temporary workers? Then payroll is often the most practical solution.

When is payrolling less of a fit?

Consider alternatives if:

• You mainly have permanent, long-term staff
• You want maximum control over every process
• Cost is your absolute priority and you have the time to run payroll yourself
• You already have a well-oiled HR department

The costs at a glance

Payroll companies work with a conversion factor, usually between 1.65 and 1.82. This means:

Gross salary per hour	Payroll factor	Cost to you
€12	1.70	€20.40
€15	1.70	€25.50
€20	1.70	€34.00

For comparison: running payroll yourself costs, as a rough guide, a factor of 1.55 to 1.65 (2026 figures). So the difference is around 5 to 15 percent, depending on your sector and any NSSO reductions. The exact wage cost also depends on your Joint Committee and the associated collective labour agreement (CLA).

Belgian context: lower risk than in the Netherlands

Here's an important nuance. In Belgium, employment conditions such as holiday days, pension and health insurance are highly standardised. The risk that your employee misses out on benefits because you opted for a cheap payroll company is therefore more limited than in the Netherlands.

Belgian legislation protects employees well, regardless of the arrangement they work under. That said, you should still choose a recognised partner that knows the rules.

Checklist: is payrolling right for you?

Answer these questions:

1. How many temporary or flexible workers do you have per year?
2. How much time do you currently spend on payroll administration?
3. How often do you feel stressed about Dimona deadlines or NSSO calculations?
4. How important is the legal bond with your staff to you?
5. What is your budget for HR services?

More than three temporary workers per year, more than 5 hours a month on admin, regular stress? Then payrolling is probably a good investment.

In short

Payrolling is no miracle cure. It costs more than running payroll yourself, and you hand over control. But for employers who rely on flexible staff and have no appetite for admin, the advantages often outweigh the costs.

The honest truth? It depends on your situation. Anyone who won't tell you that honestly is trying to sell you something.

Frequently asked questions

Is payrolling more expensive than running payroll yourself?

Yes, on average 2 to 4 percent. You're paying for the service, the risk coverage and the admin. Whether that's worth it depends on how much time you save and how much value you place on peace of mind.

What are the risks of payrolling?

The biggest risk is a poor payroll partner. Choose a recognised provider with knowledge of Belgian legislation. On top of that: no replacement when someone is sick (you have to arrange that yourself) and less direct grip on the processes.

Who is payrolling not suitable for?

Employers with mainly permanent, long-term staff and a well-oiled HR department benefit less from payroll. In that case, the costs don't outweigh the advantages.

Can I hire a payroll employee permanently later on?

Yes. Most payroll contracts include an intake procedure. Discuss the terms with your payroll partner beforehand.
