Customer concentration is common in privately held companies.
One major account may have helped the business grow, improve its product, and establish credibility. The same account may represent a large share of revenue, margin, receivables, and management attention.
A buyer will assess both sides.
Measure more than revenue
Concentration should be reviewed using more than total sales.
Management should understand each major customer’s share of:
- revenue;
- gross profit;
- receivables;
- order backlog;
- sales pipeline;
- operating capacity;
- customer-support effort.
A customer may represent 20 percent of revenue but a much larger share of profit. Another may generate high sales but weak margin and slow payment.
Understand the relationship
A buyer will want to know:
- how long the customer has worked with the company;
- whether there is a written contract;
- when the contract expires;
- whether pricing can be changed;
- whether the contract can be assigned;
- who owns the relationship;
- whether the customer has credible alternatives;
- whether service performance is stable.
A longstanding customer relationship may be durable even without a long contract. That durability still needs to be explained.
Test owner dependence
If the selling owner personally controls the relationship, the risk is greater.
Introduce additional executives and account managers before the sale process. Ensure that customer history, pricing, obligations, and open issues are documented in company systems.
The customer should trust the business, not only one individual.
Reduce concentration through real growth
The most effective way to reduce concentration is to grow other customers.
That may require:
- a clearer target market;
- additional sales capacity;
- new channels;
- improved lead generation;
- geographic expansion;
- new products or services;
- stronger account development.
Do not add low-quality revenue simply to change the percentage. New business should improve the company, not only the presentation.
Prepare for buyer questions
Management should be able to explain:
- why the customer buys;
- renewal history;
- commercial terms;
- margin;
- expected future demand;
- current relationship quality;
- competitive position;
- downside if the customer is lost.
A buyer may apply additional protections where concentration is high. These may affect price, payment timing, warranties, or transaction structure.
Qualified legal and financial advisers should review any proposed terms.
Do not hide the issue
Customer concentration becomes more damaging when it appears late in a process or conflicts with the seller’s earlier presentation.
Disclose it accurately and explain the operating facts.
A concentrated customer base does not automatically make a company unattractive. It makes the quality, durability, and transferability of those relationships more important.
