Worried About Dependence on a Major Customer? Decide Who to Serve Next Before Cutting Business
A major customer brings steady work. Yet you may worry about what would happen if its orders fell, and feel pressure to find new customers quickly.
Separate reducing the relationship from preparing for dependence. Being chosen by a major customer is not itself a problem. Examine what would happen if the relationship changed, and what value you could offer others. Spreading revenue across customers does little good if scattered work erodes profit.
Look beyond the revenue share
Start with the latest year of revenue, gross profit by project, payment terms and time spent serving major customers. For seasonal work or large projects, examine several years too. Use a consistent method for calculating gross profit and make the burden of additional work visible.
List dedicated equipment, staffing, inventory and development costs separately. Distinguish resources you could use elsewhere from those tied to this customer. Two businesses with the same revenue concentration can face different remaining costs if orders change.
With the person responsible for finances, model both reduced orders and a complete stop. Put expected receipts, payments, reducible spending and remaining fixed costs into a cash forecast. These are scenarios, not predictions. Use them to discuss when and under what conditions action would be needed. This article sets no universal percentage at which concentration becomes dangerous.
Who else would pay for the same capability?
Establish what the customer values: compatibility with particular equipment, predictable delivery or help with a production process. Compare order records with the customer's words rather than filling gaps with your own assumptions.
Do other customers need that capability? Buyers in the same industry may require different specifications and purchasing conditions. Buyers in another industry might share the same operational problem. For each candidate group, record the problem, alternatives considered, required delivery capability and time needed to sell.
Even when prospects are separate companies, examine whether they share end customers, investment timing or factors that drive orders. In a scenario involving a market downturn, could the new relationships be affected too? Separate increasing customer numbers from reducing exposure to relationships that may change at the same time.
This is where brand strategy enters the decision. Which customers should choose your company, and for what value? That choice guides investment, staffing and sales priorities. Trust earned with an existing customer cannot be transferred to a new market merely by declaring that it applies.
The U.S. National Institute of Standards and Technology's Baldrige Criteria Commentary includes customer and market requirements, risks and core competencies among considerations for strategic planning.[1] It is a management framework, not a study establishing a safe number of customers. The reviews and trials proposed here are practical recommendations.
Test one customer group at a time
Narrow the candidates and begin with work whose scope and required effort you can estimate. Examine responses to proposals and the economics of actual delivery. Reserve the capacity needed for existing commitments, then set the sales time, spending and review date for the trial.
Look beyond new revenue. Will you need equipment or additional staff? What must be paid before the customer pays you? Could existing delivery dates be affected? The same revenue can bring different profit and cash requirements. More sales prospects do not, by themselves, complete your preparations.
Building channels beyond referrals addresses ways to reach customers. This article focuses on the business exposure created by concentrated trade and the choice of whom to serve next. Customer interviews can help establish why you were chosen.
If a cash shortage is imminent, work with your lender and financial advisers before waiting for new sales. Check obligations relating to long-term contracts and dedicated investments individually.
