Vendor Segmentation: A Strategic Guide in 4 Steps

Does your company manage hundreds or even thousands of vendors? Then you know that not every vendor has the same strategic importance. Some are essential to operations, others supply interchangeable standard products.

Treating all vendors the same is a common but costly mistake. It leads to inefficient processes, untapped savings and higher supply chain risk. The solution is a systematic approach: strategic vendor segmentation.

What is vendor segmentation?

Vendor segmentation (also called supplier segmentation) is a strategic process in procurement and supply chain management that divides the entire vendor base into groups (segments). The grouping is based on predefined criteria such as purchasing volume, supply risk, strategic importance or innovation potential.

The goal is to stop managing all vendors the same way and instead set a suitable management and development strategy for each segment. That way you use your resources more effectively.

Why is strategic segmentation essential?

Moving from reactive, administrative purchasing to proactive partner management is hardly possible without segmentation. It is the foundation of effective vendor management. The main benefits:

• Focused resources: Not every vendor needs the same attention. You concentrate time and people on strategic partners and minimize the effort for transactional vendors through automation.
• Effective risk management: You identify vendors with high supply risk, such as monopolists for critical components, and can take action, for example with second sources or contingency plans.
• Better vendor relationships: You develop the right strategy for each collaboration. With strategic partners, innovation and development come first; with leverage vendors, prices and terms. Differentiated supplier relationship management delivers better results for both sides.
• More efficiency, lower costs: When procurement processes match the segment, administrative effort falls. Automated ordering platforms suit C-parts, while strategic goods need intensive negotiation and joint planning.

Vendor segmentation in 4 steps

Successful vendor segmentation is not a one-off project but a process you review and adjust regularly. It breaks down into four phases.

Step 1: Define goals and collect data

First decide what you want to achieve: reduce risk, save costs, drive innovation or a combination. These goals determine which criteria matter.

Then collect the vendor data you need. The starting point is usually a spend analysis: how much do you spend with which vendor? Other data points include delivery reliability, quality, terms, certifications and results from vendor audits. Segmentation is only as good as your data.

Step 2: Choose a segmentation model and set criteria

ABC analysis works well for an initial prioritization. It groups vendors according to the Pareto principle: a few A vendors account for most of the purchasing volume. However, the approach is one-dimensional and ignores supply risk.

For strategic segmentation, the Kraljic matrix has become the standard. It assesses two dimensions:

• Profit impact: How strongly does the purchased item affect profitability or the quality of the end product? Factors include purchasing volume, contribution to margin and market differentiation.
• Supply risk: How hard is it to source? Criteria include the number of available vendors, logistical complexity, monopolies and market volatility.

Combining the two produces four segments: strategic vendors, leverage vendors, bottleneck vendors and routine vendors. Learn more in our article on the Kraljic matrix.

Step 3: Analyze and assign vendors

Now assign each relevant vendor to a segment based on your criteria. Involve not only procurement but also production, quality assurance and R&D. That way you assess the criticality of components correctly and take a vendor's innovation potential into account.

Risk assessment is becoming more important. Laws such as the German Supply Chain Due Diligence Act (LkSG) require a closer analysis of vendor risks, especially regarding human rights and environmental standards. With a few vendors, a spreadsheet is enough. With hundreds or thousands, you need SRM software or an e-procurement platform that collects data automatically and makes the segmentation traceable.

Step 4: Develop and implement strategies for each segment

Segmentation only delivers its real value with the right strategy for each segment:

• Strategic vendors (build partnerships): They are critical to success. The goal is long-term partnerships with joint development projects, close process integration and regular strategic alignment, including at management level.
• Leverage vendors (use competition): Low supply risk and high volume give you a strong negotiating position. Use it with regular tenders, volume bundling and firm price negotiations.
• Bottleneck vendors (secure supply): Availability comes first. Useful measures are safety stock, qualifying second sources or standardizing components to reduce dependency.
• Routine vendors (automate processes): Low risk and low value contribution, so process efficiency is what counts. The goal is ordering that is as automated as possible, for example with e-procurement systems, catalogs or purchasing cards.

Bringing routine vendors together digitally

In indirect procurement, most vendors usually fall into the routine segment: office supplies, safety equipment, tools, C-parts. The biggest lever here is process cost. According to HTWK Leipzig, digital procurement reduces it from €146 to €86 per order.

On simple system, more than 28,000 buyers order from over 1,000 vendors through one access point, at their own negotiated terms. Approvals run digitally, and order data goes straight into the ERP. That leaves more time for strategic vendors.

Conclusion

Moving away from a one-size-fits-all approach to vendor management is the step from administration to strategic value creation. A differentiated view of vendors brings cost advantages and, above all, focus: routine tasks are automated and resources go into business-critical partnerships. That strengthens your company's capacity for innovation and resilience.
