In many SMEs, initial growth relies on one or two key customers. This situation is often interpreted as positive because it ensures workload, improves revenue visibility and allows the company to scale with a certain degree of stability. However, from a financial perspective, customer dependency introduces a risk that is often underestimated, especially when the business grows around that relationship.
The problem does not necessarily arise when a customer is lost, but much earlier. A reduction in orders, a change in commercial terms or a delay in payments may be enough to affect the company’s liquidity. The greater the customer’s share of total revenue, the greater the financial impact of any variation.
In addition, dependency often shapes the structure of the business. The company hires staff, invests in machinery or expands facilities to handle the expected volume. This structure becomes rigid and difficult to adjust if the customer reduces its activity. The risk lies not only in revenue, but also in the company’s ability to adapt.
Another relevant factor is bargaining power. When a customer accounts for a significant share of revenue, it has greater capacity to put pressure on prices, extend payment terms or demand certain conditions. The company accepts these conditions in order to maintain volume, but profitability and liquidity progressively deteriorate.
This scenario is common among industrial SMEs, subcontractors or service companies linked to large corporations. Growth comes quickly thanks to a key customer, but diversification does not keep pace with that growth. The company increases in size without reducing its exposure to risk.
From a strategic perspective, dependency is not always negative, particularly in the early stages. It can help consolidate activity and gain experience. However, it should be actively managed, avoiding a situation in which growth increases the business’s vulnerability.
The recommendation for an SME in this context is to periodically analyse sales concentration and establish internal dependency limits. It is advisable to set progressive diversification targets, develop new business lines and prioritise customers that reduce the relative weight of the main accounts. In addition, it is advisable to avoid structural investments exclusively linked to a single customer and to negotiate terms that protect liquidity. This approach makes it possible to maintain growth without increasing financial risk and improves business stability in the medium term.
