Werkvertrag (contract for work and services)
What makes a German works contract, how it differs from employment and agency work, and what follows where the arrangement is only nominal.
1. What is Werkvertrag (contract for work and services)?
Under a Werkvertrag the contractor owes, under Section 631 BGB, a result – a thing to be produced or a state of affairs to be brought about. The contractor organises the work itself, deploys its own staff under its own instructions and bears the entrepreneurial risk: if the work is not delivered, it is not paid for.
That is to be distinguished from a contract of employment under Section 611a BGB. There what is owed is work performed under instruction and determined by another – not a result, but labour. And distinct again is hiring-out of employees (Arbeitnehmerüberlassung), where a business places its own employees with a third party to work under that party's instructions.
On paper these three can be told apart cleanly; in day-to-day operations they are hard to keep apart. And what counts is not the label in the contract but the way the arrangement is actually operated. Where the two diverge, lived practice decides – that is the central point about this term.
A note on terminology for readers used to English-language practice: "contractor" covers all of this and more. German law asks three separate questions here, and each carries different consequences.
2. Origin and development
The Werkvertrag is a contract type of general civil law and initially has nothing to do with employment law. It gained employment law significance only once it began to be used as a structuring alternative to employing people: buying in services through works contracts rather than hiring staff avoids dismissal protection, co-determination, social security contributions and collective agreement coverage.
In some sectors this became a business model – most visibly in meat processing, where entire production stages were awarded to works contract firms whose staff were in fact integrated into the client's own operations. The legislature responded for particular sectors with direct restrictions.
For all others the general dividing line still applies – and it is shaped by case law, not by a statutory definition of the bogus works contract. The decisive features are practical: who gives instructions? Who plans the deployment? Whose equipment is used? Is the work owed described in a way that can actually be delimited?
3. Core principles and how it works
A result, not an activity
The contractor owes a delimitable outcome. If the work owed cannot be described, that tells against a works contract.
Own instructions, own organisation
The contractor's staff take their instructions from the contractor, not from the client. Technical instructions given by the client to another firm's staff are the clearest counter-indication.
Entrepreneurial risk
Warranty, rectification, payment on acceptance: anyone billing by time spent and carrying no defects risk is not performing a works contract.
Lived practice beats the contract
Where the contract text and the way it is operated diverge, the operation governs. A carefully drafted contract then does not help – it documents the divergence.
A bogus works contract is concealed hiring-out
Where work is in fact performed under instruction within the client's operation, this is hiring-out of employees. Without a licence or the prescribed disclosure, the AÜG can bring an employment relationship with the client into existence.
The contributions risk sits with the client
If an audit finds employment, the client owes the total social security contributions retrospectively – including the employee's share, which it can scarcely reclaim.
The criminal law boundary
Where contributions are withheld, Section 266a of the Criminal Code may be engaged. That is not a theoretical limit but a real issue in audit proceedings.
4. Who is Werkvertrag (contract for work and services) relevant for?
- Businesses buying in services – IT, logistics, maintenance, cleaning, construction. - Procurement and operating departments – they conclude the contracts and live them, often without knowing the employment law classification. - Works contract firms – for them the structure determines their own exposure. - Works councils – the use of external staff engages co-determination rights. - HR – they carry the consequences when an outsourcing arrangement is reclassified.
5. How it differs from related terms
- Works contract and contract for services – a contract for services owes an activity without guaranteeing a result, but likewise without subjection to the client's instructions. - Works contract and contract of employment – Section 611a BGB turns on being subject to instructions and integrated into another's work organisation. - Works contract and hiring-out of employees – on a hiring-out the supplier remains the employer, but instructions come from the client. That is the middle case between the two, and in law it is the category a bogus works contract falls into. - Works contract and status determination – with sole traders the social security status question under Section 7a SGB IV arises in addition. - Works contract and outsourcing – outsourcing is the commercial term; in law it is implemented through works or service contracts, possibly combined with a transfer of undertaking.
6. Variants and adaptations
Structures and their risk profile:
- Award of a clearly described package of work – a construction phase, say, or a software component with formal acceptance. The unproblematic case. - Long-term deployment within the client's operation – risky, because integration suggests itself. Physical separation and the contractor's own equipment reduce the exposure. - Deployment billed by time spent – hourly billing without acceptance tells strongly against a works contract. - A precautionary hiring-out licence – no longer protects since the disclosure duty came in; the hiring-out must be expressly designated in the contract and the individual identified. - Sectors with specific restrictions – there the award of particular activities to outside firms is directly limited.
7. Advantages and challenges
Advantages
- Makes it possible to buy in services the business does not maintain in-house
- The risk of non-delivery sits with the contractor, including warranty
- Clearly delimitable packages of work can be managed and billed cleanly
- No headcount commitment where demand fluctuates or is one-off
- Specialist expertise is bought in rather than built up
Challenges
- The dividing line is hard to hold in day-to-day operations
- A bogus works contract can create an employment relationship with the client
- The client then owes the entire social security contributions retrospectively
- Criminal law exposure under Section 266a of the Criminal Code where contributions are withheld
- Everyday technical instructions tip the classification without anyone noticing
- The label on the contract offers no protection – only lived practice counts
8. Best practices for implementation
Make the work describable
If you cannot say in a few sentences which delimitable outcome is owed, it is not a works contract. That test is simpler and more revealing than any contract review.
Separate the instruction paths organisationally
A named contact at the contractor, no direct allocation of tasks to its staff. That is the point at which outsourcing arrangements fail in practice.
Train the operating departments, don't just review contracts
The classification arises in daily dealings. Conclude the contract cleanly and then let the team lead hand out tasks, and you have a bogus works contract.
Use the status determination procedure where in doubt
With sole traders, Section 7a SGB IV settles the social security side in advance – and an early application can avoid retrospective effect.
Actually operate acceptance and warranty
Where nothing is ever formally accepted and nothing ever rectified, the defining feature of a works contract is missing from daily practice.
9. Tips for employers and employees
For employers
- **Lived practice decides** – not the heading on the contract
- **No instructions to another firm's staff** – that is the clearest counter-indication
- **The contributions risk is yours** – including the employee's share
- **A precautionary hiring-out licence no longer protects** – the hiring-out must be disclosed
For employees
- **Who gives you instructions is an indication** – of who your actual employer is
- **Concealed hiring-out can create an employment relationship** – with the business you work in
- **You can apply for a status determination yourself** – Section 7a SGB IV
- **Document your own equipment and market presence** – they tell in favour of self-employment
10. Conclusion
A works contract owes a result, a contract of employment owes work performed under instruction, and hiring-out of employees sits between them. On paper that is clear; in daily operations it holds only for those who separate the instruction paths organisationally.
Because what counts is not the label but the way the arrangement is actually operated. Where the operating department allocates tasks to the contractor's staff day by day, this is hiring-out of employees – and where the licence or the disclosure is missing, the AÜG can bring an employment relationship with the client into existence. On top of that comes the contributions risk: the entire social security contribution retrospectively, including the employee's share, which is scarcely recoverable.
The most useful test is a banal one: can you say in a few sentences which delimitable piece of work is owed? If not, even the most careful contract drafting will not help.
