What do you pay when you work with a temp agency?
You need extra hands, and you need them fast. But what does a temp worker actually cost, and how is that pay worked out through an agency? It's the question that keeps coming back.
Working with agency staff has become a firm fixture of the Flemish labour market. Companies increasingly turn to temporary agency work when they need extra people at short notice, without taking on the full administrative burden of a permanent hire.
Register temporary staff through an agency and you won't pay per individual payslip. You pay an all-in rate based on a coefficient. It sounds complicated at first, but in practice it's the most transparent way to know your total staffing cost from the outset. The coefficient is a multiplier applied to the gross salary of a temp worker, with every mandatory element built in: NSSO (National Social Security Office) contributions, holiday pay, payment of wages, allowances such as insurance, and even the administrative follow-up of social documents.
The big advantage? No hidden costs, and the complete cost picture at a glance, with no surprises on the invoice. The temp agency acts as the legal employer of the temp worker and takes contract management, Dimona (immediate employment declaration) filings, Joint Committee (JC) applications and payroll processing entirely off your hands. So you can focus on operational needs, while the administrative responsibility stays with the agency.
In short: choosing temporary agency work means choosing clarity. You know exactly what you'll pay in advance, and the agency guarantees that every legal obligation, from the end-of-year bonus to professional withholding tax, is applied correctly. In this article, we take a closer look at the system behind temp work, so you understand exactly how a temp worker's pay is built up, which rights come with it, and when temporary agency work can be more efficient than a direct hire.
Recruitment & selection, or payroll?
At Recruit, you decide how far our support goes. Prefer to find candidates yourself and just use our software to register temporary staff quickly and error-free? You can. In that case, we take over the full wage and contract administration through payroll, while you keep recruitment in your own hands.
Want us to help find the right candidates as well? Then we combine payroll with the recruitment and selection of staff. We post your vacancies, interview the applicant, and then send them through to you.
What does the coefficient rate cover?
The coefficient rate is a single, all-in price based on the gross salary of a temp worker: everything, from NSSO contributions to payroll processing, sits in one formula. So when you employ a temp worker through a temp agency, you don't pay separate costs per payslip or social contribution. It may look technical at first glance, but that's exactly what makes it transparent, and it tells you precisely what your staffing cost comes to.
The coefficient covers every legal and administrative obligation that comes with temporary employment through an agency. The temp agency acts as the legal employer of the temp worker and guarantees correct compliance with the Joint Committee and the applicable collective labour agreements (CLAs). This way you avoid errors, hidden costs or delays in payroll administration.
What exactly is included in the coefficient rate?
- Contract management : Drafting, follow-up and digital archiving of every employment contract.
- Dimona declarations to the NSSO : Timely registration of every start and end of employment.
- Social contributions : NSSO contributions and sectoral funds.
- Occupational accident insurance : Coverage and administrative follow-up in the event of occupational accidents.
- Holiday pay and end-of-year bonus : Automatic settlement according to employee rights.
- Payroll processing : Gross salary, net salary, bonuses, meal vouchers and other benefits.
- Joint Committee & CLA compliance : Correct application of salary scales and indexations.
- Administrative follow-up : Extensions, absences and terminations of assignments.
- Legal updates : Continuous monitoring of new legislation and social regulations.
Since the agency handles all of this, you don't have to calculate, check or archive anything yourself. That makes the coefficient model especially attractive for companies that want to switch gears fast, with no risk of errors or penalties. You keep operational control, while the administrative worry is lifted off your plate.
When do extra recruitment costs apply?
Extra recruitment costs apply only when a role calls for more than standard temporary agency work, that is, active recruitment and selection on top of the employment itself. In most cases, the standard coefficient rate is all it takes to bring in a temp worker through an agency, and that rate covers both payroll processing and the full administrative follow-up. When a company is looking for scarce profiles or needs extra staff at very short notice, the temp agency offers not only employment, but also active recruitment and selection, often through specialised channels or headhunting.
Any separate selection fee is always agreed in advance, so you know exactly where you stand as an employer. It's never about hidden costs, but about a transparent charge for extra services that go beyond standard temporary agency work.
When does an additional recruitment cost apply?
- For hard-to-fill or niche profiles
- For urgent vacancies that have to be filled within 24 to 48 hours
- For active headhunting, personality tests or in-depth screenings
What do you get in return?
- Publication of vacancies on specialised job platforms and social media
- Pre-selection of CVs, including a first online meeting before we send the candidates through
- Selection on soft skills, experience and cultural fit within your organisation
- Presentation of one to three candidates who are immediately deployable
This service saves you valuable recruitment time and cuts the risk of a mismatch. The agency doesn't just supply workers; it supplies candidates who genuinely fit the role, the team and the company culture. That turns temporary employment through an agency into an efficient, high-quality solution.
Why transparency means peace of mind
Transparency brings peace of mind because an employer knows exactly, in advance, what a temporary worker will cost, with no hidden surcharges or complex settlements afterwards. It's one of the biggest advantages of working with a temp agency. Every element, from a temp worker's pay to social contributions, bonus and administration, is brought together in one clear rate through the coefficient model. That makes budgeting easier and builds trust between the employer and the temp agency.
On top of that, your staffing partner takes on the full administrative responsibility. From the Dimona declaration to the management of social documents: every aspect of the temporary employment is followed up according to the Joint Committee the sector falls under. So employers don't have to worry about CLA updates, indexations or regulatory compliance. Everything is applied automatically by the legal employer of the temp worker.
Three core advantages of transparency in temporary agency work:
- No hidden costs : Gross salary, NSSO contributions, bonus and administration all sit in one coefficient.
- No unexpected administration : Forms, contracts and Dimona are processed directly by the agency.
- No legal uncertainty : Thanks to continuous monitoring of CLAs, sectoral agreements and Joint Committees, everything is legally watertight.
In other words: transparency brings peace of mind. You know exactly what will land on the invoice, with no risk of corrections or disputes down the line. That trust in the administrative side lets companies focus on their core business, while the agency guarantees correct, reliable payroll processing.
The concrete benefits of temp agency work
Choosing temporary agency work through a temp agency brings not only flexibility, but clear operational benefits for employers. When a temporary worker is correctly employed through an agency, administrative obligations such as Joint Committee rules, NSSO obligations and payroll processing are taken entirely off your hands. That makes the system especially interesting for companies that want to switch gears quickly, with no risk of errors in social documents or the employment contract.
Another benefit of the coefficient model is that you save time and internal resources. HR teams no longer have to deal with wage calculations, professional withholding tax or keeping track of CLA changes. Everything is managed by your staffing partner, so you can focus on your organisation's core business. This is especially valuable for temporary employment during peak periods, replacements or projects with a short turnaround time.
Three direct benefits for your company:
- Faster onboarding : A temp worker can be registered and on the job within a few hours.
- Lower administrative burden : Your HR department focuses on people, not on paperwork or NSSO forms.
- Less risk of errors : Indexations, CLA adjustments and wage corrections are followed up automatically.
Time is money, especially in sectors with seasonal peaks or sudden replacements. A clear coefficient model delivers direct savings in working hours and avoids error corrections after the fact. This way you combine flexibility with certainty, without compromising on the quality of employment.
Worry-free payroll, handled correctly
Registering temporary staff doesn't have to be complex or risky. Whether you work with a temp agency or run a payroll tool yourself, success stands or falls on clear agreements, correct application of the law and transparent rates. Only then do you avoid surprises in the payroll settlement and guarantee watertight administration, fully in line with the regulations on temporary agency work and the Joint Committee the temp worker falls under.
A reliable payroll partner makes sure that all social documents, employment contracts and NSSO obligations are carefully followed up. That gives you, as an employer, not only legal certainty, but also the freedom to focus on your core business, without worrying about salary scales, absences, or the correct calculation of the end-of-year bonus. Transparency in costs and processes brings peace of mind, for small businesses and larger SMEs alike.
