What is payrolling?
Payrolling is an arrangement in which a provider takes on the payroll and administrative employer role for a worker that the client company sourced itself. The provider issues the contract and pays the worker; the client selected the person and directs the work.
The distinguishing feature is what the provider does not do. It does not find the candidate. It picks up a hiring decision that has already been made and handles the employment paperwork behind it.
How is payrolling different from an Employer of Record?
Two things separate them, and both matter. The first is why the arrangement exists: payrolling outsources administration for a client that usually already has a local entity, while an Employer of Record (EOR) exists precisely because the client has no legal vehicle to hire anyone locally. The second is scope: an EOR is solving a presence problem, payrolling is solving a workload problem.
An umbrella company sits on the other side of the table again, because there it is the contractor who engages the provider rather than the client.
Why does Belgium treat payrolling carefully?
Because Belgian law tightly restricts making personnel available to a third party. If a provider employs someone on paper while the client exercises the real employer authority over that person, the arrangement starts to resemble exactly what the restriction exists to prevent.
The practical consequence is that payrolling in Belgium is normally routed through licensed temporary-work agency structures rather than set up as a free-standing administrative service. Getting this wrong is not a technicality. The client can end up being treated as the employer, with every obligation that follows.
What does payrolling mean for you as the worker?
You are an employee, with a payslip, statutory deductions and statutory protections, and the entity named on your contract is not the organisation whose team you join. That affects practical things: who approves your leave, who you raise a pay question with, and what happens to you when the assignment ends.
It is worth knowing which arrangement you are actually in before you start, because payrolling, an interim contract and an umbrella route give different answers to all three. Sparagus states the contract type on each of the roles currently open.
