Your largest customer wants more. For an SME under pressure to grow, that can be welcome news. How much of the business’s next decision now depends on that one relationship?
Imagine a small manufacturer. A regular customer increases its orders and asks for a dedicated production slot. Sales sees a stronger relationship. Delivery reserves capacity. Finance considers equipment that would make the extra work possible. Leadership expects the account to keep growing.
In this constructed example, the order is real. The question is what else the business begins treating as dependable: the next order, the customer’s preferred specification, or its willingness to keep paying the same price.
More revenue, a narrower choice?
The IFRS Foundation’s overview of IFRS 8 includes major-customer disclosures alongside information about business activities and economic environments. Its stated scope concerns entities with publicly traded debt or equity. That is not a reporting instruction for every SME; it is a useful reminder that the revenue total does not tell the whole story about where revenue comes from.
For the imagined manufacturer, the strategic question is what happens to its choices. Could it serve a different customer with the same equipment? What work is displaced by the reserved slot? If the large account changes direction, which commitments would still be the manufacturer’s to carry?
A close customer relationship can justify investment and specialisation. Spreading effort across more accounts can carry costs of its own. The size of an account alone does not settle which choice is sound.
What is the growth plan relying on?
Our working theory asks how decisions across sales, delivery, finance and leadership support one another. Here, the question is whether all four recognise the same dependence before they commit the business around it. A strong relationship and room to respond to change are different sources of confidence.
When your largest account grows, does your freedom to make the next decision grow with it?
