Customer segmentation can be very nuanced, incorporating elements of product, geography, buying behavior, needs, etc. Those with a less sophisticated approach often segment customers based on size. It is a natural starting point. Larger customers generate more revenue, so they receive better pricing. Smaller customers pay more. The logic is straightforward, but even if you’re only focused on customer spend, it’s incomplete.
Customer size reflects what a customer is today. It does not capture what they could become. And in many cases, it overlooks the very opportunities companies are trying to unlock. This is where customer potential changes the equation. Share of wallet measures how much of a customer’s total spend you capture. This provides a more forward-looking view of value. A large customer with low share represents unrealized opportunity. A smaller customer with high share may already be fully penetrated. Treating both purely based on current revenue leads to missed growth and misaligned pricing. The difference is subtle, but the impact is significant.
When pricing is based only on size, it tends to reward scale, regardless of future opportunity. High-potential customers may be overcharged, limiting their willingness to grow. At the same time, fully penetrated customers may continue to receive favorable pricing even when there is little incremental upside. Over time, this creates inefficiency. Margin is given away where it is not needed and withheld where it could drive growth.
Segmentation based on customer potential addresses this directly. By incorporating share of wallet into pricing, companies begin to differentiate not just by who the customer is, but by how they engage and what they could become. Pricing becomes more aligned with opportunity, not just history.
More importantly, pricing itself becomes part of the value proposition. Instead of being a static outcome, price becomes a mechanism to create mutual benefit. Customers are given a clear path to earn better pricing through increased share, deeper engagement, or broader adoption of the supplier’s offerings. The supplier, in turn, captures more volume and strengthens the relationship. This creates a true win-win dynamic.
Customers are not simply asking for lower prices; they are incentivized to grow in order to access them. Pricing reinforces the behaviors that drive long-term value, rather than reacting to short-term negotiation pressure. This is where segmentation begins to do its real work. The purpose of segmentation is not just to categorize customers—it is to enable the business to provide and price solutions that are a better fit for how different customers operate. When segmentation reflects both size and potential, it becomes far more effective at achieving that goal.
Customers who are early in their relationship can be supported with pricing that encourages growth. More mature, fully penetrated customers can be priced in line with the value they receive. High-potential accounts can be prioritized strategically, with pricing used as a lever to accelerate development.
The result is a more intentional pricing system. Sales teams are no longer forced to make case-by-case decisions based on limited context. Instead, they operate within a framework that aligns pricing with both current value and future opportunity. Customers experience greater consistency, while still seeing pricing that reflects their specific situation.
Over time, this approach drives better outcomes. Growth is concentrated where it matters most. Margins are preserved where it is no longer needed as an incentive. And pricing becomes a tool for shaping customer behavior, rather than simply responding to it.
The shift from customer size to customer potential is not just a refinement in segmentation. It is a shift in how pricing is used. It moves pricing from a backward-looking metric to a forward-looking strategy—one that aligns the interests of both the supplier and the customer, and ultimately delivers stronger, more sustainable results.
