How many active suppliers do you have in your ERP right now? Be honest. You probably have between 200 and 500. And now, the real question: how many do you actually know? Their performance, their financial risks, their innovation capabilities? If the honest answer is “the top 20, maybe”, you have a resource allocation problem.

Supplier Segmentation is not a database cleanup tool. It’s your supplier portfolio management strategy.— Fundamental principle of Category Management

The classic situation: you have 500 active suppliers, but 64% of them represent less than 2% of your total spend. These 320 suppliers consume 40% of your buyers’ administrative time. Meanwhile, the 12 strategic suppliers that represent 65% of your spend receive 15% of your attention. You’re managing the irrelevant.

Segmentation inverts this imbalance. It transforms your portfolio into a piloted strategic asset.

The real problem: managing the irrelevant

Here’s the snapshot of most organizations I meet:

• 500 active suppliers in the ERP
• 64% represent < 2% of total spend (320 suppliers for a minor share)
• These 320 suppliers = 40% of buyers’ admin time
• The 12 strategic ones = 65% of spend = 15% of attention received
• Zero visibility on financial risks or potential problems

The result: your procurement team spends 80% of its time on decisions that affect only 5% of your P&L, and just 20% on decisions that make up 65%.

It’s inverted workforce management. And it costs a lot.— Observable reality in 70% of mid-market organizations

Segmentation changes everything. It allows you to:

• Reduce your supplier base from 500 to 80-100 relevant suppliers
• Redirect 40% of buyer time towards strategic categories
• Generate savings: 12% on average via consolidation and renegotiation
• Reduce procurement administrative costs by 35%
• Lower risks: financial audit of strategic suppliers

The 4 typical segments

Not all suppliers should be managed the same way. There are 4 clearly distinct segments, each with its own management logic. Here’s how to define and activate them.

The 2×2 segmentation matrix

How do you concretely position your suppliers? Use a 2×2 matrix with:

• Y-axis (Strategic Value) : spend + Kraljic criticality + innovation potential
• X-axis (Performance) : quality + delivery + price + compliance + collaboration

The scoring method

Here’s how to objectively score each supplier. It’s quantifiable — not a feeling.

Apply this scoring to all your suppliers. Yes, it takes time the first time. But you have an objective, defensible segmentation with your management.

Practical case: the manufacturing company

Let’s say a real situation: a manufacturing company with 350 active suppliers, 8 buyers, 45M€ in external spend. Here’s how segmentation restructured them over 3 years.

Initial situation

The diagnosis jumps out: 64% of suppliers (tail spend) represent 2% of spend but consume 35% of buyer time. That’s exactly the opposite of what you should be doing.

3-year action plan

Results after 3 years

• −71% of supplier base (from 350 to 100)
• +40% of buyer time redirected to strategic suppliers
• 12% savings via consolidation and renegotiation
• −35% of admin costs for procurement (fewer POs, fewer invoices)
• Zero supplier bankruptcies (financial audit instituted)
• +3 new innovative contracts with strategic suppliers

Supplier Business Reviews (SBR): the engine of strategic suppliers

Once you’ve segmented, real management begins. For strategic suppliers, the key tool is the Supplier Business Review (SBR).

What is an SBR?

It’s a structured meeting with your strategic supplier, once per quarter, lasting 3 hours, that transforms a transactional relationship into a true partnership.

Typical format of a quarterly SBR

Typical participants: Category Manager, Procurement Director, operational representative (product/logistics), Supplier CEO/COO.

Strategic suppliers with regular SBRs perform on average 15–20% better on their KPIs than those without them. It’s the effect of shared attention.— Empirical data observed

Classic mistakes to avoid

Integration with the tool series

Supplier Segmentation doesn’t exist in isolation. It’s one of 6 tools — it draws from the others and feeds them.

If you haven’t done Spend Analysis, you segment on bad data. If you don’t have Kraljic, you don’t really know if a supplier is strategic or just high-volume. True power comes from using them together.

In summary

Supplier Segmentation transforms administrative chaos into piloted portfolio strategy. You move from “we manage 500 suppliers poorly” to “we manage 100 really well”.

• 4 distinct segments: Strategic, Preferred, Transactional, Phase-out
• 2×2 matrix to position: Strategic Value vs Performance
• Objective scoring: not a feeling, quantified data
• Effort reallocation: 40% buyer time gain
• SBR for strategic suppliers: transform relationships into partnerships
• 12% average savings via consolidation and renegotiation
