The legal relationships and consequences of a subcontracting agreement sound complicated—and they are, in fact, one of the drawbacks of this legal arrangement. While it is easy to “purchase,” so to speak, the services of an electrician through a contract for work or services within the framework of a subcontracting agreement, the prime contractor thereby loses control over the electrician’s work and, in the worst-case scenario, is liable for substandard performance or damage. Although the resulting consequences can be asserted against the subcontractor, this may, in the worst-case scenario, require a new court proceeding.
What is a subcontracting agreement?
A subcontract is a contract between a prime contractor (general contractor) and a subcontractor, under which certain parts of a larger contract are delegated to the subcontractor. The subcontractor performs these services independently and is not subject to direct instructions from the principal of the main contractor.
The legal basis is generally a contract for work and services or a service contract under the German Civil Code (BGB). The subcontracting agreement governs the scope of services, compensation, deadlines, liability, and—most importantly—the issue of subcontractor liability.
In which industries are subcontractors particularly common?
Subcontractors have proven particularly effective in the following industries:
- Construction Industry: Electrical, plumbing, drywall, scaffolding—almost every trade is handled by subcontractors.
- Logistics: Transportation services, last-mile delivery, warehousing.
- IT Sector: Software development, testing, IT support.
- Tourism: Transportation companies, lodging, tour guides.
- Agriculture: Seasonal work, harvesting, use of machinery.
- Local Public Transit (ÖPNV): Transportation services (limited to a maximum of 50 % under EU law).
What are the benefits for companies and subcontractors?
Benefits for the Parent Company
- In light of the shortage of skilled workers, subcontractors make it possible to pool important resources. Through subcontractors, specialized expertise can be made available to the general contractor whenever it is needed. When there is no immediate need, other companies can draw on these resources.
- This also makes workforce utilization more efficient and saves money for the general contractor. Instead of paying an electrician who isn't needed at the moment, the general contractor only pays for the work when it is actually needed.
- The parent company avoids the hassle and legal risks associated with permanent employment: finding and hiring employees, drafting an employment contract, and potentially letting a skilled worker go when business is slow.
- Subcontractors can use their resources to handle peaks in order volume. Whenever there is a particularly heavy workload, they can help out the main company—without the main company having to maintain a permanent staff.
- Since the subcontractor specializes in this service, it can usually provide it better and faster than the main contractor—with higher quality at lower costs.
Benefits for the subcontractor
The advantages for the subcontractor stem from the fact that it benefits from its specialized expertise and available resources. These resources are then utilized more efficiently, thereby avoiding idle time while costs continue to accrue.
In the travel and tourism sector, for example, transportation companies are often contracted as subcontractors for these reasons. However, other services—such as lodging and tourist assistance—can also be outsourced to other companies in this way.
Subcontractors provide additional transportation services for local public transit. It should be noted that an EU-mandated quota applies: A maximum of 50 % of transportation services may be outsourced to subcontractors.
Disadvantages and Risks of a Subcontracting Agreement
Loss of Control and Liability Risk
The main drawback for the prime contractor is the loss of control: it cannot issue direct instructions to the subcontractor on how to perform the work. If the subcontractor fails to perform adequately or causes damage, the parent company is still liable to the client—and must then assert its claims against the subcontractor in separate proceedings. In the worst-case scenario, this means double the effort: damage control externally and legal action internally.
Subcontractor Liability
Special caution is required here. The prime contractor is responsible for ensuring that the subcontractor Social Security contributions pays as required. If that is not the case, the parent company is in fact liable for them—it acts as a guarantor for these contributions.
Subcontractor Liability: What General Contractors Need to Know
If a subcontractor fails to pay its employees’ social security contributions correctly, the prime contractor is secondarily liable for them. This liability can only be limited through careful contract drafting and regular documentation requirements for the subcontractor (e.g., exemption certificates, social security statements).
An Overview of Other Risks
- Quality Control: Since the subcontractor is not directly accountable to the client, quality assurance can be more difficult than it is with in-house staff.
- Communication effort: Coordination between the prime contractor, subcontractors, and the client requires clearly defined points of contact and responsibilities.
- Contractual Loopholes: Poorly drafted subcontractor agreements can lead to disputes over the scope of work, deadlines, and compensation.
- No direct contact with end customers: For the subcontractor, this often means that it cannot establish a direct relationship with customers and therefore has less market presence.
What are the benefits of a subcontracting agreement for new businesses?
Subcontracting agreements offer particular advantages for new businesses. Since startups often have limited resources, subcontracting allows them to take on parts of larger projects. This enables them to take on even larger projects without incurring costs that would persist after the project ends—such as payroll costs and social security contributions for employees they would have to hire themselves.
For companies that operate as subcontractors, the advantage is that they are able to secure contracts right from the start. In addition, their customer base expands: they often collaborate with other subcontractors and come into contact with the prime contractor. The prime contractor may then subsequently hire the subcontractor directly for specific projects. This is particularly helpful for new companies, whose scope of operations expands significantly through their work for the prime contractor.
Ultimately, this gives both prime contractors and subcontractors the opportunity to take on more complex tasks. This helps new companies build a better reputation and secure follow-up contracts through the project.
However, these benefits do not always materialize. Generally speaking, there is no direct contact between the subcontractor and the prime contractor. Consequently, a subcontract does not always result in an expansion of the subcontractor’s customer base.
What must a subcontracting agreement include?
A well-drafted subcontracting agreement protects both parties. The most important areas covered include:
- Scope of Services: A precise description of the work or service to be provided—as specific as possible to avoid any room for interpretation.
- Compensation and Payment Terms: Clear provisions regarding wages, due dates, and payment terms.
- Deadlines and Milestones: Binding deadlines for partial work and completion.
- Warranty and Liability: Provisions governing the subcontractor's liability for defects, delays, or damages.
- Subcontractor Liability: The subcontractor's obligations to provide proof and file reports regarding social security contributions.
- Prohibition or Authorization of Subcontracting: Whether the subcontractor is permitted to subcontract the work to third parties.
- Confidentiality and Data Protection: Handling of Project Information and Personal Data.
Conclusion
A subcontracting agreement is a double-edged sword. It offers the prime contractor significant advantages: cost savings, flexibility, access to specialized expertise, and better capacity utilization during peak periods. For the subcontractor, it opens doors to contracts, networks, and growth—even for young companies with limited resources.
However, this comes with real risks: loss of control, liability for third parties, subcontractor liability for social security noncompliance, and increased coordination efforts. Those who minimize these risks through careful contract drafting, clear scope of work descriptions, and contractual obligations to provide evidence benefit from one of the most flexible models of modern business organization.
Frequently Asked Questions About Subcontracting Agreements
A contract for work and services directly governs the relationship between a client and a contractor. A subcontract is also a contract for work and services—however, it is entered into by the prime contractor with a third party in order to delegate parts of an existing contract. The prime contractor remains fully liable to the original client.
Subcontractor liability means that the prime contractor is secondarily liable for the subcontractor’s social security contributions if the subcontractor fails to meet its payment obligations. This liability can be limited through contractual obligations to provide proof: The subcontractor must regularly submit proof of social security payments and a certificate of good standing. Exemption certificates from the tax office are also an important protective measure.
Subcontracting agreements are particularly common in the construction industry (electrical work, plumbing, drywall installation, scaffolding), in logistics (transportation, last-mile delivery), in the IT sector (software development, testing), in tourism (transportation, lodging), in agriculture (seasonal work), and in local public transit. In local public transit, an EU-mandated limit of a maximum of 50 % outsourcing applies.
For entrepreneurs, acting as a subcontractor allows them to get involved in complex projects without having to hire their own staff. Collaborating with the prime contractor and other subcontractors expands their network and can lead to direct follow-up contracts. In addition, startups can build a reputation through their specialized services and strengthen their market position.
The prime contractor remains fully liable to the client and must assume responsibility for defects—regardless of whether they were caused by the subcontractor. The prime contractor may subsequently assert warranty claims and claims for damages against the subcontractor. In the event of a dispute, this may result in separate legal proceedings. Therefore, clear scope of work descriptions and liability provisions in the subcontract are essential.
Only if the subcontracting agreement expressly permits it. In practice, subcontracting is often restricted or made subject to approval, as the prime contractor would otherwise lose all control over the performance of the services. Without a corresponding contractual provision, independent subcontracting by the subcontractor is generally not permitted.
