Catalog structure: Systematic organization of product data in Procurement
November 19, 2025
The catalog structure forms the backbone of an efficient procurement organization and significantly determines the user-friendliness of e-procurement systems. It defines the hierarchical arrangement and categorization of products and services in digital procurement catalogs. A well-designed catalog structure reduces search times, minimizes procurement errors, and supports strategic purchasing decisions. Read on to find out what catalog structure is all about, what structuring methods exist, and how you can make the best use of them in the procurement process.
Key Facts
- Hierarchical structure of products and services in digital procurement catalogs
- Direct impact on user-friendliness and efficiency of e-procurement systems
- Supports spend analysis and strategic purchasing decisions through consistent categorization
- Reduces maverick buying through improved discoverability of approved products
- Enables automated workflows and approval processes based on product categories

Definition: Catalog structure
The catalog structure refers to the systematic arrangement and categorization of products, services, and information in digital procurement catalogs.
Basic components
An effective catalog structure comprises several levels of product classification. The top level consists of main categories such as "IT hardware" or "office supplies," followed by subcategories and specific product groups.
- Main categories for broad product areas
- Subcategories for more detailed segmentation
- Product attributes for specific characteristics
- Search filters for targeted product discovery
Catalog structure vs. product group management
While master data management focuses on technical data maintenance, the catalog structure concentrates on user-oriented presentation. It complements strategic product group concepts with intuitive navigation.
Importance of catalog structure in Procurement
A well-designed structure supports e-procurement by reducing search times and improving compliance. It also enables precise spend analysis and supports strategic procurement decisions through consistent categorization.
Methods and procedures
Developing an optimal catalog structure requires systematic approaches and proven methods for categorization and organization.
Taxonomy development
The basis for this is a well-thought-out taxonomy that combines business requirements with user expectations. Product hierarchies are structured according to logical criteria such as intended use, supplier, or cost center.
- Analysis of existing procurement data and patterns
- Definition of uniform categorization rules
- Consideration of industry-specific standards
Content management strategies
Effective catalog content management ensures that the structure is continuously maintained and updated. Automated workflows support the consistency and quality of product data.
User-oriented design
The structure is geared toward the needs of end users and their procurement processes. Guided buying rules direct users to the desired products and reduce incorrect orders through intuitive navigation.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Important KPIs for catalog structures
The effectiveness of the catalog structure is measured using specific key performance indicators that reflect both technical performance and user experience.
usage metrics
Key indicators include the average search time to find the desired product, the number of searches per order, and the abandonment rate during product searches. These metrics directly reflect the user-friendliness of the structure.
- Average time to find a product
- Searches per successful purchase
- Catalog abandonment rate and bounce rate
Compliance key figures
The ratio of orders placed via the structured catalog to free-text orders measures structural acceptance. In addition, the ratio of approved to unapproved products shows the effectiveness of the approval workflow.
Data quality indicators
The completeness of product attributes, the timeliness of price data, and the consistency of categorization determine the structural quality. Regular audits reveal inconsistencies and support continuous improvement.
Risks, dependencies and countermeasures
An inadequate catalog structure can pose significant operational and strategic risks for the procurement organization.
Structural inconsistencies
Inconsistent categorization leads to data silos and makes comprehensive analysis difficult. Different departments may develop their own structures, which jeopardizes standardization and compliance.
- Implementation of uniform governance processes
- Regular structural audits and cleanups
- Key responsibilities for catalog maintenance
Technical dependencies
The structure is closely linked to the underlying IT architecture. System changes or updates may require extensive adjustments. An overly complex structure can also impair performance.
User acceptance risks
An unfriendly structure leads to circumvention and maverick buying. Lack of training and unclear navigation significantly reduce the efficiency gains of the e-procurement system.

Practical example
A medium-sized manufacturing company is implementing a new catalog structure for its e-procurement system. The previous alphabetical sorting is being replaced by a functional structure: main categories such as "production materials," "IT equipment," and "facility management" form the top level. Subcategories are based on production lines and cost centers. The integration of search filters for suppliers, price ranges, and availability reduces the average order time by 40%. The new structure also enables precise spend analyses by product category and supports strategic supplier negotiations.
- 40% reduction in order time thanks to intuitive navigation
- Improved donation transparency through uniform categorization
- Increased compliance through improved findability of approved products
Current developments and effects
The catalog structure is constantly evolving, driven by technological innovations and changing user requirements in the digital procurement environment.
AI-supported categorization
Artificial intelligence is revolutionizing automatic product categorization and assignment. Machine learning algorithms analyze product descriptions, images, and usage behavior to suggest optimal structures and continuously improve them.
- Automatic product classification using NLP methods
- Dynamic adjustment based on user behavior
- Predictive analytics for demand forecasts
Personalized catalog views
Modern systems offer customized structures based on user roles, departments, or historical procurement patterns. This improves the user experience and significantly speeds up procurement processes.
Integration of external data sources
Networking with supplier catalogs and marketplaces requires flexible structures that harmonize different data formats and standards. Punchout catalogs and standardized interfaces enable seamless integration of external content.
Conclusion
The catalog structure forms the foundation of successful e-procurement systems and has a significant impact on efficiency, compliance, and user acceptance. A well-designed, user-oriented structure reduces procurement times, improves data quality, and supports strategic purchasing decisions. Modern technologies such as AI-supported categorization and personalized views open up new opportunities for optimization. Companies should regularly review their catalog structures and adapt them to changing requirements in order to realize sustainable procurement advantages.
FAQ
What is the difference between catalog structure and product catalog?
The catalog structure defines the organizational structure and navigation, while the product catalog contains the specific content and product data. The structure forms the framework in which the product information is presented.
How often should a catalog structure be revised?
A fundamental review is recommended annually, while continuous adjustments should be made in response to changes in the product portfolio or new business requirements. User feedback and performance metrics provide indications of where optimization is needed.
What role does the catalog structure play in spend analysis?
A uniform structure enables precise expenditure analyses by category, supplier, and cost center. It forms the basis for strategic procurement decisions and supplier consolidation through comparable data sets.
How does the catalog structure influence user acceptance?
An intuitive, needs-based structure significantly increases acceptance and reduces circumvention behavior. Complex or illogical structures, on the other hand, lead to frustration and maverick buying, which counteracts e-procurement goals.
