Definition: Complaint management
Complaints management covers all activities for the systematic handling of complaints and objections in the procurement process.
Core elements of complaints management
Complaints management consists of several components that build on each other:
- Recording and documentation of quality defects and delivery problems
- Evaluation of the complaint according to urgency and impact
- Communication with the supplier concerned
- Tracking of corrective measures until complete resolution
Complaints management vs. quality management
While quality management works preventively, complaints management reacts to problems that have already occurred. However, both areas complement each other perfectly, as complaint data provides valuable insights for needs analysis and supplier evaluation.
Importance in Procurement
Effective complaint management strengthens the negotiating position with suppliers and supports the procurement strategy through data-based decisions when selecting suppliers.
Methods and procedures
Various proven methods enable structured and efficient processing of complaints in Procurement.
8D method for complex complaints
The 8D method (Eight Disciplines) offers a systematic approach to problem solving:
- Team building and problem definition
- Immediate measures to limit the damage
- Root cause analysis and corrective measures
- Preventive measures to avoid recurrence
Digital complaint recording
Modern IT systems support digital procurement through automated workflows. These enable seamless documentation and significantly shorten processing times.
Supplier evaluation through complaint data
Complaint statistics are incorporated into the regular supplier evaluation and support decisions in supply base optimization. Frequent complaints can lead to a reassessment of the supplier relationship.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Important KPIs for complaint management
Measurable key figures enable the continuous monitoring and improvement of complaints processes.
Processing time and solution rate
The average processing time per complaint and the proportion of successfully resolved cases show the efficiency of the process:
- Average processing time in working days
- Resolution rate as a percentage of cases processed
- Escalation rate for complex complaints
Complaint rate by supplier
The number of complaints per supplier and time period enables an objective assessment of supplier quality. This data supports decisions in the assessment of delivery capability.
Cost impact
The direct and indirect costs caused by complaints illustrate the economic benefits of effective complaint management and justify investments in improvement measures.
Risks, dependencies and countermeasures
Inadequate complaint management can have a significant impact on costs, quality and supplier relationships.
Delays in processing
Long processing times lead to production downtime and customer complaints. Clear escalation channels and defined response times in the purchasing guidelines minimize these risks.
Incomplete documentation
A lack of documentation makes tracking and root cause analysis more difficult. Standardized data entry screens and mandatory data fields ensure complete documentation of all relevant information.
Supplier relationships under pressure
Improper complaint handling can put a strain on business relationships. Professional communication and constructive solutions as part of stakeholder management maintain long-term partnerships.

Practical example
An automotive supplier implements a digital complaint management system for its 200 suppliers. Following a quality complaint about electronic components, an 8D report is automatically triggered. The supplier concerned receives a structured complaint with all relevant data within 24 hours. Systematic processing allows the cause to be identified quickly and a permanent solution to be implemented.
- Reduction in processing time from 14 to 5 days
- Increase the solution rate to 95
- 30% improvement in supplier quality
Current developments and effects
Complaints management is constantly evolving due to technological innovations and changing market requirements.
AI-supported complaints processing
Artificial intelligence is revolutionizing complaints processing through automatic categorization and prioritization. AI in Procurement enables the prediction of recurring problems and supports preventative measures.
Integration in Supply Chain Visibility
Modern complaints systems are closely linked to supply chain visibility. This enables a holistic view of supplier performance and quality trends along the entire value chain.
Proactive complaint management
The trend is moving from reactive to proactive complaint processing. Through data analysis and pattern recognition, potential problems can be identified and prevented before they occur.
Conclusion
Complaints management is an indispensable building block for successful procurement processes and sustainable supplier relationships. Through the systematic processing of complaints and consistent root cause analysis, it makes a significant contribution to quality assurance and cost optimization. The integration of modern technologies and data-based approaches makes it possible to move from reactive to proactive problem handling and thus sustainably strengthen the company's competitiveness.

The processing time depends on the complexity. Simple complaints should be processed within 48 hours, complex cases with an 8D report can take up to 30 days. Immediate confirmation of receipt is important.
What role does documentation play in complaints management?
Complete documentation is essential for tracking, root cause analysis and legal protection. It also enables statistical evaluation for the continuous improvement of supplier quality and process optimization.
How can complaints management contribute to supplier development?
Complaint data identifies weak points at suppliers and enables targeted development measures. Constructive cooperation in problem solving strengthens the partnership and leads to sustainable quality improvements.
