Introduction: Why industrial purchasing is more in demand than ever

Industrial procurement is under increasing pressure: volatile markets, growing raw material shortages, a lack of skilled workers, and a heightened awareness of sustainability are forcing companies to optimize their internal processes for maximum efficiency and transparency. In this context, the systematic optimization of the procurement process is gaining strategic importance.

This isn’t just about cost savings – it’s about speed, data quality, risk management, and the ability to better utilize internal resources. The following twelve best practices address key levers along the operational and tactical procurement process – specifically for industrial purchasing organizations with heterogeneous demand structures.

Procurement Process Optimization – Summary for Decision-Makers

• Differentiate processes: Product group-specific processes reduce complexity and throughput time by up to 40%.
• Consistently utilize systems: Digital requirements and e-procurement solutions reduce approval times by up to 40%.
• Strategically integrate suppliers: Early integration reduces replenishment times by up to 50%.
• Data-driven management: KPI reporting increases profit contributions in indirect purchasing by up to 30%.
• Institutionalize improvement: The PDCA cycle delivers annual process improvements of 8–12%.

1. Fundamentals of process optimization in purchasing

An efficient procurement process is characterized by a short cycle time, low processing effort per order, and high process quality (e.g., first-time-right rate). In practice, however, historically grown processes, a lack of transparency regarding requirements, an inefficient supplier structure, and inadequate system support often hinder a consistent process logic.

The goal of process optimization is to separate value-adding from non-value-adding activities, shorten lead times, and reduce operational costs in purchasing, accounts payable, and related functions. Key performance indicators (KPIs) such as the lead time from the time of demand to invoice approval, the percentage of automated orders, or the number of suppliers per product group serve as objective metrics.

1.2 Best Practices for Optimizing the Industrial Procurement Process

1. Product group-based process differentiation

Problem: Many purchasing organizations use a uniform procurement process for all product groups – regardless of value, complexity, or procurement risk. This leads to simple C-parts going through the same approval process as capital goods or technical services. The result: unnecessary bureaucracy, long lead times, and a mismatch between the effort and risk profile of the purchased item.

Recommendation: Structure your purchasing processes along clearly defined commodity group categories. Develop differentiated process routes – e.g., shortened approval chains for routine requirements, standardized review steps for framework agreement items, or individual coordination for investment projects. Use commodity group trees in your ERP system and implement rule-based workflows tailored to complexity and value.

Benefits: Differentiation allows for more targeted resource allocation: Critical needs receive greater attention, and standard processes run faster and more reliably. Companies report lead time reductions of up to 40% in simply structured product groups. Simultaneously, process acceptance among specialist departments and internal customers increases due to transparent, customized workflows.

2. Systematic bundling of needs

Problem: Individual departments often procure goods in isolation and on short notice. Without centralized management, such individual needs lead to numerous orders, small quantities, and one-off suppliers. This fragmentation not only increases prices but also burdens accounts payable, causes inconsistencies in supplier terms, and makes contractual safeguards more difficult.

Recommendation: Conduct regular demand analyses – ideally automated from your ERP system. Identify frequently requested items, services, or product groups and bundle them strategically in tenders, framework agreements, or delivery schedules. Work closely with the relevant departments to consolidate demand periods and call-off quantities.

Benefits: Strategically implemented bundling significantly increases purchasing effectiveness: better prices through volume, predictable deliveries, and reduced administrative costs. The number of orders can often be reduced by 20–30%, while simultaneously increasing delivery reliability and reducing maverick buying.

3. Integration of suppliers into the planning process

Problem: Suppliers often only learn of a need when an order is placed. This leads to long delivery times, unnecessary communication efforts, and inventory risks for the customer. Particularly in direct procurement – for production materials or critical components – this information asymmetry leads to supply bottlenecks or expensive rush orders.

Recommendation: Involve strategic suppliers in your demand and production planning early on. Utilize forecast-sharing models, blanket orders, or vendor-managed inventory (VMI) approaches. Consignment warehouses are another option, where the supplier maintains inventory at the customer’s site, which is only invoiced upon withdrawal. These models can be directly integrated into ERP or SCM systems.

Benefits: Early transparency creates reliability on both sides: Suppliers can better plan their capacities, and purchasing departments reduce operational stress and safety stock levels. Companies report up to 50% shorter replenishment times and significant efficiency gains in logistics and production supply. The supply risk is measurably reduced.

4. Establishing clear responsibilities and process owners

Problem: Many purchasing processes fail not because of systems, but because of unclear responsibilities. Who is responsible for approvals, who checks requirements, who negotiates terms? In practice, this leads to delays, duplicate inquiries, or unauthorized individual decisions – especially in matrix organizations with multiple locations or business units.

Recommendation: Define clear roles and responsibilities for each step in the procurement process. Appoint a process owner with technical and operational responsibility who can coordinate across departments and implement optimization potential. Supplement this structure with clearly documented escalation paths and regular process evaluations by the purchasing committee.

Benefits: Clear responsibilities increase accountability in the process. Decisions are made faster, queries are minimized, and processes become more transparent. Procurement gains confidence and becomes visible as the process owner – not as a supplicant. Studies show that companies with clear process responsibility achieve, on average, 25% higher on-time delivery rates in order processing.

5. Digital Requirements Management

Problem: In many companies, requirements are communicated informally – via email, telephone, or even verbally. This makes it difficult to track, delays approvals, and leads to additional work in purchasing, such as through queries, clarifications, and manual data entry. It becomes particularly problematic when information is incomplete or not transmitted in accordance with ERP systems.

Recommendation: Implement a system-supported requirements management system. Utilize self-service portals where employees can enter structured requirements, including units of measure, account assignments, and delivery date preferences. Define validation rules, mandatory fields, and automated approval workflows. Technically, this can be achieved via existing ERP systems (e.g., SAP Fiori) or specialized e-procurement portals.

Benefits: Structured data input significantly reduces the coordination effort for purchasing. Data quality improves, and processing times decrease. In practice, approval times can be reduced by up to 40%, while simultaneously creating a reliable data foundation for analysis. Purchasing is relieved of administrative burdens and can focus more on value-adding activities.

6. Use of classic and AI-supported e-procurement systems

Problem: Many purchasing departments struggle with inconsistent ordering processes and media breaks. Employees order from various online shops without integration into ERP or approval systems. Purchasing loses control over product ranges, suppliers, and prices – leading to maverick buying, a lack of transparency, and high process costs.

Recommendation: Integrate a central e-procurement system that combines webshop connections (PunchOut), approved suppliers, and product group catalogs. Supplement this with intelligent search functions, automatic cost center allocation, and—where possible—AI-powered demand suggestions that take historical data and budget guidelines into account.

Benefits: A professional e-procurement system reduces media breaks, improves the user experience, and ensures that orders are only placed with contractually bound partners. Purchasing departments report cost reductions of up to 20% for C-items and a significantly improved compliance rate. At the same time, automation relieves the burden on purchasing staff.

7. Data-driven management via purchasing KPIs

Problem: Many purchasing departments operate without a reliable data foundation. Processes are managed intuitively, weaknesses are identified subjectively, and improvement measures are implemented without proof of effectiveness. Without systematic key performance indicators (KPIs), the basis for prioritization, management, and performance monitoring is lacking.

Recommendation: Define a set of relevant procurement KPIs – aligned with process, price, and supplier quality. Examples: average lead time, order costs per transaction, maverick rate, framework agreement percentage, delivery reliability. Collect this data automatically in the ERP system and visualize the results in dashboards or reports – also for other stakeholders.

Benefits: Key performance indicators (KPIs) enable fact-based decisions and targeted improvements. Procurement becomes manageable, measurable, and comparable. Companies with established KPI systems report up to 30% better results in indirect procurement – solely through focused process optimization and targeted supplier development.

8. Automated invoice processing & matching processes

Problem: In many organizations, invoice verification is still paper-based or manual. Employees check documents individually, compare them with orders and delivery notes, and forward approvals via email. This is error-prone, time-consuming, and often leads to lost early payment discounts or late payments.

Recommendation: Implement automated invoice processing with integrated three-way matching (order – goods receipt – invoice). Utilize OCR technologies, e-invoicing standards, or specialized tools for automated processing. Integrate approvals into a central workflow system – with escalation mechanisms and status tracking.

Benefits: The processing time for incoming invoices is significantly reduced, early payment discounts are reliably utilized, and inquiries are minimized. In mature systems, the rate of automated processing exceeds 70% of all invoices, resulting in enormous efficiency gains and a significant reduction in workload for specialist departments. Simultaneously, transparency in financial and purchasing controlling increases considerably.

9. Reduction of the number of creditors

Problem: In many purchasing organizations, the number of vendors is constantly growing – particularly due to individual orders from various online shops, specialist suppliers, or project partners. This diversity results in high administrative costs for vendor management, lengthens payment processes, and increases the risk of duplicates, incorrect payments, or compliance violations.

Recommendation: Consolidate your supplier base strategically – for example, through prioritized framework agreement partners, central supplier platforms, and an external service provider like FACURA for special requirements. Additionally, every new vendor account should be subject to an approval process, including data verification, compliance screening, and contractual terms.

Benefits: A reduced number of creditors not only means less effort for purchasing and accounting, but also better terms through volume bundling and greater reliability in processing. Studies show that reducing the number of creditors by 20% can save up to 30% in administrative costs without compromising security of supply – provided the alternatives are integrated into the system.

10. Process cost-based make-or-buy decisions

Problem: Many operational purchasing decisions – for example, regarding special requests, repairs, or services – are handled internally out of habit, even though the process costs significantly exceed the procurement value. At the same time, there is no systematic basis for assessing whether in-house procurement or outsourcing is more economically viable.

Recommendation: Base make-or-buy decisions on data: Collect internal process costs for each order type (e.g., material costs, time expenditure, IT effort) and compare them with external service models. Develop decision matrices based on value, frequency, risk, and strategic relevance – ideally in coordination with controlling and relevant departments.

Benefits: Transparent criteria enable informed decision-making. Procurement can selectively outsource recurring small orders, while internal resources focus on value-adding tasks. Companies report up to 50% lower process costs for outsourced standard procurement – without loss of quality, but with increased process stability.

11. Involvement of purchasing in early project phases

Problem: In many companies, purchasing departments are only involved in technical or investment projects at a late stage – often only after the requirement has already been reported or suppliers have been pre-selected. This results in a lack of negotiating leverage, overlooked contractual risks, and untapped standardization potential.

Recommendation: Integrate purchasing as a core component of project and development processes – for example, through defined involvement in project planning, specification review rounds, and joint supplier evaluations. This requires a clear understanding of roles, project methodology expertise within the purchasing department, and support from top management.

Benefits: Early involvement leads to more well-thought-out specifications, more realistic budgets, and more professional risk management. Companies that consistently integrate procurement into the early project phase achieve cost savings of up to 15% on investment projects – not through price negotiations, but by avoiding unnecessary requirements and selecting smart suppliers.

12. Continuous process improvement using the PDCA cycle

Problem: Many purchasing departments optimize reactively: in response to complaints, audits, or when budget targets are missed. A structured approach to systematically reviewing, questioning, and improving processes is lacking. As a result, inefficient processes often remain unchanged for years.

Recommendation: Establish a continuous improvement process (CIP) based on the PDCA cycle: Plan – Do – Check – Act. Conduct regular process reviews, analyze deviations from key performance indicators, actively involve operational users, and implement concrete measures with assigned responsibility and deadlines. Document changes and communicate successes.

Benefits: A structured continuous improvement process (CIP) establishes a learning organization. Problems are identified earlier, solutions are more widely adopted, and processes are made more resilient. Companies that regularly conduct process evaluations report sustained higher process stability, improved user satisfaction, and significant reductions in operational process costs over the years.

Conclusion: Process optimization as a strategic design area in purchasing

Optimizing the procurement process is far more than an operational efficiency project – it is a crucial lever for the strategic development of the purchasing function. Only those who systematically analyze, differentiate, and continuously improve processes can transform purchasing from a reactive processor into a controlling, value-creating entity.

The 12 best practices presented demonstrate that there is no universal standard process – but there are proven approaches for efficiently managing different types of needs, organizational structures, and system landscapes. The key is to start with realistic, measurable measures that are internally compatible and offer genuine added value – for purchasing, specialist departments, and management alike.
