The risk of reliance on a major customer – a cautionary tale

27th February 2025

I was recently appointed administrator of a company which had reliance on one major customer, in this case the customer represented over 95% of the turnover of the company. This brought to mind a previous liquidation where a business in a completely different sector was in the same situation.

In both cases the customer withdrew orders from the company. In the previous case the company had no contract with the customer so they had the right to move elsewhere at will. In the most recent case, there was a contract in place and the company directors believed the customer had no legal right to terminate. What then followed was a legal dispute which remains ongoing.  

In both cases, with over 90% of turnover suddenly switched off, the companies had no cashflow to continue to trade, and in the second case, no funds to enter into a legal dispute.

The danger of overdependency

Whilst a loyal customer is always something to strive for, having reliance on one can have catastrophic effects.  

What lessons can be learned

In both cases the directors had enjoyed a good relationship with their customer, until the relationship soured. They did not see the issue coming and with hindsight would not have allowed one customer to have become so pivotal. So, what advice can be given to avoid others having the same issues?

Conclusion

This is unlikely to be the last time I see a company director in a state of panic due to the loss of their principal customer. Whilst directors cannot control what their customer does, they can put plans in place to mitigate the risk as far as possible.  

The key when trouble appears is to take proper advice and remember that whilst early advice is always best, it is never too late to seek professional guidance.
