Service contract: definition, application and legal basis in Procurement
November 19, 2025
A service contract regulates the provision of services between the client and service provider and is a key instrument in modern procurement management. In contrast to purchase contracts, the focus here is not on the delivery of goods, but on the provision of expertise, work or specialized services. Find out below what characterizes a service contract, what legal particularities need to be taken into account and how you can use this type of contract strategically in Procurement .
Key Facts
- Service contracts regulate the provision of services without a guarantee of success, in contrast to contracts for work and services
- The legal basis is formed by §§ 611-630 BGB with specific obligations for both contracting parties
- Typical areas of application: IT services, consulting, maintenance, facility management and personnel services
- Remuneration is usually based on time or effort, not on specific work results
- Particular importance in differentiating between bogus self-employment and temporary employment

Classification & purpose of service contracts
The service contract is a fundamental form of contract in procurement that is characterized by specific legal and practical features.
Legal basis and delimitation
According to Section 611 of the German Civil Code (BGB), the service provider undertakes to provide the promised services, while the client is obliged to pay the agreed remuneration. The key difference between this and a contract for work and services is that there is no guarantee of success in a service contract - it is the proper performance that is owed, not a specific result.
Service contract vs. contract for work
While the service contract focuses on the work itself, the contract for work and services aims to achieve a specific, definable result. This distinction has a significant impact on warranty, remuneration and risk-bearing. In the case of service contracts, the client bears the risk of the desired result; in the case of contracts for work and services, the contractor bears the risk.
Meaning of service contract in Procurement
In strategic Procurement , service contracts enable the flexible procurement of expertise and capacities without long-term personnel commitments. They are particularly relevant for outsourcing strategies and the integration of external specialists in development projects.
Structure, contents and application
The structured design of service contracts requires precise definitions and clear regulations on the scope of services, remuneration and quality standards.
Essential components of the contract
A professional service contract includes a precise description of the services to be provided, quality requirements, deadlines and milestones as well as remuneration arrangements. Special attention should be paid to regulations on data protection, confidentiality and intellectual property.
- Performance description with measurable criteria
- Service Level Agreements (SLAs) and quality standards
- Remuneration structure and billing modalities
- Liability and warranty regulations
Contract management and control
The successful implementation of service contracts requires continuous monitoring and active management. Regular reviews, performance measurements and adjustments ensure target achievement and cost efficiency.
Integration into procurement processes
Service contracts must be seamlessly integrated into existing procurement processes. This includes supplier evaluation, risk management and coordination with internal stakeholders to ensure service delivery.

KPIs and verification criteria
The measurement and evaluation of services requires specific key figures and evaluation criteria that take into account the special nature of service contracts.
Key performance indicators and service level
Service Level Agreements (SLAs) define measurable quality and performance standards. Typical KPIs include availability times, response times, solution rates and customer satisfaction. These KPIs enable objective performance evaluation despite the lack of a guarantee of success.
- Availability and accessibility (e.g. 99.5% uptime)
- Response and processing times
- Quality indicators and error rates
- Customer satisfaction and Net Promoter Score
Key performance indicators
The financial evaluation of service contracts is carried out using cost-benefit analyses, productivity indicators and benchmarking comparisons. Total cost of ownership (TCO) and return on investment (ROI) help with the strategic evaluation of service investments.
Compliance and key risk figures
Compliance KPIs monitor adherence to legal and contractual requirements. Risk indicators such as supplier concentration, degrees of dependency and probabilities of default support proactive risk management in service procurement.
Contractual risks and hedging for service contracts
Service contracts entail specific risks that can be minimized through appropriate contract design and risk management strategies.
Legal risks and compliance
The distinction between bogus self-employment and temporary employment poses a considerable legal risk. Unclear contract design can lead to additional claims under social security law and consequences under labor law. Particular caution is required in the case of permanent services and activities subject to instructions.
Performance and quality risks
As service contracts do not include any guarantee of success, the client bears the risk of inadequate results. A lack of service definition, a lack of quality standards and inadequate monitoring can lead to project failures and additional costs.
- Unclear service delimitation and scope creep
- Quality defects without the right to rectification
- Dependence on key persons at the service provider
Operational and financial risks
Cost overruns due to time-based remuneration, vendor lock-in effects and a lack of scalability can jeopardize the profitability of service contracts. Professional vendor management and regular market analyses are essential for minimizing risk.

Practical example
A car manufacturer concludes a service contract with an IT service provider for the maintenance and support of its ERP systems. The contract defines specific service level agreements: 99.5% system availability, maximum response time of 4 hours in the event of critical faults and monthly maintenance windows. Remuneration is based on a monthly flat rate plus variable components for additional services. Performance quality is continuously monitored and optimized through regular reviews and KPI monitoring.
- Clear SLA definition prevents service disputes
- Hybrid remuneration structure balances costs and flexibility
- Continuous monitoring ensures quality standards
Current developments and effects
Digitalization and changing working models are having a lasting impact on the development of service contracts in the modern procurement environment.
Digitalization and AI integration
Artificial intelligence is revolutionizing contract design through automated clause generation, risk assessment and compliance monitoring. Smart contracts enable automated billing and performance monitoring, while AI-based analyses identify optimization potential in existing contractual relationships.
Flexible working models and gig economy
The trend towards project-based forms of work and the gig economy requires new contract models. Hybrid forms of work, remote services and agile project structures present traditional service contracts with new challenges when it comes to legally compliant design.
Sustainability and ESG compliance
Environmental, social and governance criteria are becoming increasingly important in service contracts. Sustainability clauses, carbon footprints and social standards are becoming integral components of modern service contracts and influence supplier selection and evaluation.
Conclusion
Service contracts are indispensable instruments in modern procurement management, providing flexibility and access to specialized expertise. The legally compliant design and professional management of this form of contract require a sound understanding of the legal principles and systematic contract management. Through clear service level agreements, continuous monitoring and strategic supplier development, companies can optimally exploit the potential of service contracts and minimize risks at the same time.
FAQ
What is the difference between a service contract and a contract for work?
The main difference lies in the obligation to achieve success: in the case of a service contract, the proper activity is owed, whereas in the case of a contract for work and services, a specific result is owed. This has an impact on warranty, remuneration and risk assumption. Service contracts are suitable for consulting activities, while contracts for work and services are suitable for definable projects with defined results.
How can bogus self-employment be avoided with service contracts?
To avoid bogus self-employment, service providers should work independently, use their own resources and work for several clients. The obligation to follow instructions, fixed working hours and integration into the company organization should be avoided. Regular legal checks and clear contract design minimize the risk.
Which KPIs are particularly relevant for service contracts?
Central KPIs include service level agreements such as availability times, response times and quality indicators. Profitability indicators such as costs per service unit and customer satisfaction values complement the performance measurement. Compliance KPIs monitor adherence to legal and contractual requirements.
How can service contracts be optimally integrated into procurement processes?
Integration is achieved through structured supplier evaluation, clear definition of requirements and continuous contract management. Standardized processes for tendering, evaluation and contract conclusion increase efficiency. Regular reviews and performance monitoring ensure long-term added value from service contracts.
