The challenge
A successful consumer products business had developed a strong commercial relationship with one of its largest distribution partners.
The partnership generated substantial revenue and played an important role in the company's market position.
From a conventional sales perspective, the relationship was a success.
However, the business had become increasingly dependent on a relatively small number of major customers, with one relationship accounting for a particularly significant share of commercial performance.
This created a strategic vulnerability.
Changes in a major customer's purchasing decisions, commercial priorities or competitive position could have a disproportionate impact on the business.
The challenge was to strengthen commercial resilience without undermining the relationships responsible for much of the company's existing success.
Reducing dependence on a major customer sounds straightforward in principle.
In practice, it requires balancing competing priorities.
The business needed to protect existing revenue while developing alternative sources of growth.
Looking beyond headline performance
One of the difficulties with customer concentration is that it can remain largely invisible when sales performance is strong.
A major customer delivering consistent growth can create confidence in the commercial model.
However, revenue concentration also creates exposure to factors outside the supplier's control.
A change in management, a revised category strategy, a shift in purchasing behaviour or a deterioration in the customer's own market position can quickly affect performance.
I believed the business needed to evaluate its customer portfolio through two different lenses.
The first was immediate commercial contribution: revenue, profitability and growth potential.
The second was strategic resilience: how dependent the business had become on individual relationships and whether sufficient alternatives existed.
This broader perspective changed how I considered incremental investment.
An opportunity delivering the highest immediate return was not necessarily the one that contributed most to the long-term strength of the business.
Developing the strategy
The objective was not to reduce the value of the largest customer relationship.
That would have been commercially counterproductive.
Instead, I developed an approach that maintained support for established strategic partners while directing additional resources toward alternative growth opportunities.
This involved identifying relationships with the potential to become more significant contributors to the business.
Rather than spreading investment equally across all customers, we prioritised those where additional commercial attention could realistically improve market position and generate incremental growth.
The approach combined strategic account development with a more deliberate assessment of customer concentration.
Commercial decisions increasingly considered not only their immediate financial return but also their contribution to a more balanced customer portfolio.
The underlying principle was straightforward.
A business becomes more resilient when it has multiple strong routes to market rather than relying excessively on a single relationship.
Managing competing priorities
The strategy required patience and commercial discipline.
Major customer relationships cannot be replaced quickly, particularly in markets where distribution is concentrated among a relatively small number of participants.
There was also a risk that redirecting too much investment away from established accounts could weaken existing performance before alternative relationships had developed sufficiently.
For that reason, the approach focused on incremental rebalancing rather than abrupt change.
Existing strategic relationships continued to receive appropriate support, while additional effort was directed toward developing other commercial opportunities.
Progress was assessed through improvements in customer performance, competitive position and the contribution of alternative partners.
The strategy also needed to remain adaptable to external market developments.
Customer concentration is influenced not only by a supplier's decisions but also by changes in the wider market.
Even when alternative relationships grow, the relative importance of the largest customer may remain unchanged if that customer expands more rapidly.
The outcome
The initiative strengthened the business's competitive position with several alternative commercial partners.
Targeted investment helped generate market share improvements and create additional opportunities for growth outside the largest customer relationship.
However, the original objective of materially reducing customer concentration was not fully achieved.
External market developments continued to influence the relative contribution of major accounts.
This distinction is important.
The strategy delivered tangible improvements in alternative customer relationships, but those gains did not translate into the anticipated reduction in overall concentration.
Nevertheless, the business emerged with stronger commercial options and a more deliberate approach to managing customer portfolio risk.
The experience reinforced the importance of evaluating strategic initiatives against both their intended objectives and the value they ultimately create.
Build resilience alongside growth
Growth and resilience are related, but they are not the same thing.
A business can deliver impressive revenue growth while simultaneously becoming more exposed to a narrow group of customers.
Strong commercial leadership requires understanding both dimensions.
The objective is not simply to maximise today's revenue. It is to build a business capable of sustaining performance when customers, competitors and market conditions change.
Diversification should not come at the expense of profitable relationships, but neither should short-term commercial success obscure longer-term strategic risk.
