In a nutshell: A recruitment agency (also known as a headhunter or staffing agency) searches for and places new employees in exchange for a one-time commission. An external HR department, on the other hand, handles day-to-day HR operations for existing employees—such as contract management, onboarding, payroll support, and labor law issues—usually as part of an ongoing partnership.
We run into this misunderstanding all the time at DIGIVI: “You guys do recruiting, right?” No, not primarily, and the difference is more important than it sounds. If you choose the wrong model, you won’t end up solving the actual problem.
Recruitment in Detail
A recruitment firm—often referred to as a headhunter, recruiting agency, or HR consulting firm—has a clearly defined mission: to find and place suitable candidates for an open position. The process typically concludes with the signing of the employment contract.
- Payment is usually a one-time commission, often a percentage of the referred person's annual salary
- The focus is exclusively on filling open positions
- No ongoing support for employees after they are hired
- No risk of downtime: If someone on the team is unavailable, you won't even notice
- Scalable up or down, as needed
Outsourced Human Resources in Detail
An external HR department, on the other hand, handles the day-to-day HR tasks that arise in any company with an existing workforce—just as if you had your own HR team, only outsourced. These typically include:
- Drafting and Managing Employment Contracts
- Onboarding New Employees
- Payroll Support (Payroll Preparation)
- Answers to Everyday Labor Law Questions
- Point of Contact for Employees Regarding HR Matters
Payment is typically in the form of a monthly retainer or on a time-and-materials basis. The focus is on ongoing support, not just on filling a position, with a long-term or medium-term partnership rather than a one-off project.

When do you need what?
You need a recruitment agency if
You pay a fixed monthly fee for a defined package of services, such as contract management, onboarding support, payroll support, and ongoing advice on employment law. Retainer models start at around 800 euros per month and scale based on the number of employees and the scope of services.
You need an external HR department if
Your current workforce needs ongoing HR support, but you don’t have your own HR specialist, or your existing resources aren’t sufficient—for example, when it comes to contract issues, onboarding, or day-to-day employment law matters.
Can both models be combined?
Yes, and in practice, this often makes sense. An external HR department handles the day-to-day HR work for your existing employees, while a specialized recruitment agency is brought in for specific, hard-to-fill positions. The two models are not mutually exclusive; they address different challenges.
Frequently Asked Questions About the Difference Between an External HR Department and a Recruitment Agency
Is an external HR department the same thing as a recruitment agency?
No. A recruitment agency searches for and places new employees in exchange for a one-time fee. An external HR department handles the day-to-day HR operations for existing employees.
Does an external HR department also handle recruiting?
That depends on the scope of services agreed upon on a case-by-case basis. However, the focus is on providing ongoing support to current employees, not on traditional candidate recruitment as is the case with a staffing agency.
What doesn't an external HR department handle?
Traditional headhunting for specific specialized positions is generally still handled by specialized recruitment agencies, as is the entire payroll process; in this case, an external HR department often provides preparatory support (payroll support), but does not handle the entire payroll process.
Can I use an external HR department and a recruitment agency at the same time?
Yes, that's a common combination: ongoing HR support from an external HR department, and ad hoc assistance with hard-to-fill positions through a recruitment agency.
