How to Reduce Customer Concentration in a Food Business Before Going to Market
Knowing that customer concentration is suppressing your food business's valuation is useful. Knowing how to reduce it, in a realistic timeframe, without damaging the existing customer relationships that make the business work, is what actually changes the outcome at exit.
This article sets out a practical programme for reducing customer concentration in a UK food business over the 24 to 36 months before going to market. It is not a theoretical framework. It is the sequence of actions that produce measurable results in the trading history a buyer will assess.
Start with the Map
Before any diversification activity can be targeted effectively, you need a precise picture of the current concentration position. Not total revenue by customer, but normalised revenue by customer - stripping out any one-off or promotional elements so that the underlying trading relationship is clear.
The map should show: each customer as a percentage of total revenue; the contractual status of each relationship (signed agreement, informal course of dealing, rolling purchase order); the renewal risk of each relationship; the gross margin by customer; and the trend in each customer's revenue over the previous three years.
This map is the starting point for every diversification decision. It tells you which customers are growing, which are declining, which are contractually secured, and which represent the highest concentration risk.
The Fastest Path: Expanding Existing Customers
The fastest route to reducing the proportional weight of the largest customer is not winning new customers from scratch. It is growing the revenue from the second, third, and fourth tier customers faster than the revenue from the largest one.
Most food businesses have existing customers who are buying a fraction of what they could be buying. A retailer who buys one product line from you could potentially buy three. A foodservice customer who buys for one region could potentially buy nationally. A direct-to-consumer customer who buys occasionally could be on subscription.
Mapping the white space within existing customer relationships - the products or volumes they could logically buy but are not buying - and running a structured commercial programme to convert that white space is the fastest way to grow second-tier revenue without the cost and time of new customer acquisition.
Opening New Channels
The second most effective diversification strategy for food manufacturers is channel expansion. If the concentration is in retail, add foodservice. If it is in foodservice, add direct-to-consumer or export. Each new channel diversifies the revenue base at the structural level rather than just at the customer level.
The channel that represents the fastest diversification path depends on the specific product and production capability. For most branded food manufacturers, foodservice is the most accessible new channel because it does not require the listing fees and promotional investment that retail listings demand. For many food manufacturers, export is increasingly accessible through online channels that do not require international distribution infrastructure.
The Export Opportunity
UK Export Finance provides government-backed support for food businesses selling internationally, reducing the financial risk of entering new export markets. Export revenue is inherently diversified across multiple customers in multiple markets, which means even modest export volumes can meaningfully improve the concentration picture.
The most common barrier to export for UK food businesses at this size is not product quality or pricing - it is the working capital requirement of funding extended payment terms in international markets. UK Export Finance facilities are specifically designed to bridge this gap.
The New Anchor Customer Approach
For businesses with a dominant customer representing 35 to 50 percent of revenue, winning a new anchor customer - one that will ultimately represent 15 to 20 percent of revenue - is the most structurally impactful diversification action available. A business with one customer at 45 percent and a second at 5 percent has a fundamentally different concentration profile to one with two customers at 25 percent each, even though total revenue is unchanged.
Winning a new anchor customer in the same category requires a dedicated commercial programme over 12 to 18 months. It is not a quick win. But it is often the most commercially valuable thing a food business can do in the 24 months before a process, because the impact on the concentration metric - and therefore on the multiple - is disproportionate to the revenue added.
Documenting the Progress
The diversification programme needs to be visible in the three-year trading history that a buyer will assess. This means not just reducing the concentration but documenting the strategic intention behind it. Board minutes that record the diversification programme, management accounts that show the revenue mix moving in the right direction over time, and a clear narrative about what drove the change are all part of the evidence base that supports the improved valuation.
Frequently Asked Questions
How long does it realistically take to move from 40 percent concentration to below 25 percent?
For most food businesses, meaningful movement from 40 percent to below 25 percent takes 24 to 36 months. The timeline depends on the pace of growth in alternative channels and the rate at which the dominant customer's volume is growing or stable. A business where the dominant customer's revenue is flat will see faster concentration improvement than one where that customer is also growing.
Will my dominant customer notice the diversification?
Major retailers and foodservice operators are generally aware that their suppliers develop other commercial relationships. Most sophisticated buyers view supplier commercial resilience positively rather than as a threat to the relationship. The risk of a dominant customer reacting negatively to diversification is much lower than the cost of remaining concentrated.
Does reducing concentration require reducing volume from the largest customer?
Not necessarily. The concentration ratio improves if the total business grows while the largest customer's revenue stays flat or grows more slowly. You do not need to reduce the dominant customer's revenue - you need to grow the rest of the business faster.
How does export revenue affect the concentration calculation?
Export revenue is typically spread across multiple customers in multiple markets, which means it has an inherently diversifying effect on the concentration calculation. Even modest export revenue - 10 to 15 percent of total sales across several markets - can meaningfully improve the top customer's proportional weight.
What if I cannot diversify before I need to sell?
If the concentration cannot be reduced before the process, the priority becomes managing the buyer's perception of the risk rather than eliminating it. Clear contractual documentation of the concentrated relationship, a well-articulated narrative about the stability and history of the relationship, and a credible plan for diversification post-completion can reduce - though not eliminate - the discount applied.
