What is Customer segmentation?
Customer segmentation divides a market into groups that differ enough in behaviour or need for you to treat them differently. The classic requirements are that segments be distinguishable, reachable and large enough to justify the effort. The real test is more pragmatic though. A segment earns its name only when you actually do something different for one group than for the other: a different price, a different scope, a different channel, a different level of service.
In small and mid-sized companies, demographic axes rarely carry. More useful are the occasion somebody buys for, willingness to pay for an outcome, the service load over the term, and the buying route, meaning whether a department or a procurement function signs at the end. Sector alone is usually a sorting, not a segmentation: two firms in the same industry can run entirely opposite buying processes.
The practical payoff shows up first in the price conversation. When it is settled in advance which segment can be given which reduction in exchange for what, nobody has to improvise in the meeting. Segmentation also sorts who you chase actively and who you let be. And it has an uncomfortable flip side: any segment you do nothing differently for can be deleted. It costs maintenance and changes nothing.
Why does Customer segmentation matter?
In Simon-Kucher’s Global Pricing Study 2025 (over 2,200 executives, 28 countries, 39 industries), strengthening customer segmentation ranks among the main priorities for 2026, while average price realisation has fallen to 43 per cent. The connection is unglamorous: one price for everybody means one negotiation, and the customer runs it.
Customer segmentation in practice
- 01A service firm separates retainer clients from project clients and gives guaranteed response times only to the first group.
- 02A vendor defines three price tiers along willingness to pay rather than company size, and finds that small clients with an urgent problem pay more than large ones with time.
- 03A team stops actively pursuing a segment that delivers plenty of enquiries but has the highest churn and the longest projects.
