At Kerry Lehane Co we believe that the best growth plans begin not with ambition, but with understanding. Before any business commits to hiring, expanding premises, launching new services or entering new markets, it should have a clear and honest picture of its existing cost base. Growth built on top of an inefficient cost structure does not fix the inefficiency. It multiplies it. Every unnecessary expense, poorly negotiated contract and underused subscription travels with the business as it scales, quietly consuming the additional revenue that expansion generates. Reviewing costs before planning growth is not about cutting for the sake of cutting. It is about ensuring the foundations are strong enough to make growth worthwhile.

Many Irish SMEs have experienced several years of rising costs across wages, energy, insurance, materials and professional services. In that environment, a cost base that has not been formally reviewed in the past twelve to eighteen months almost certainly contains waste. Finding it before expansion is far easier than finding it afterwards.

Growth Amplifies Whatever Already Exists

A business that operates efficiently at its current size carries that efficiency into its next stage. A business that carries hidden waste does the same. If overheads are running five per cent higher than they need to be, that inefficiency does not disappear when revenue doubles. It doubles too.

This is why cost reviews belong at the start of the planning process rather than the end. Expansion decisions, from recruitment to new premises, are based on assumptions about profitability and available cash. If those assumptions rest on an inflated cost base, the entire plan inherits the error. Projects appear less affordable than they should be, or worse, the business commits to growth it cannot actually sustain.

Costs Accumulate Quietly Over Time

Very few businesses overspend deliberately. Costs accumulate through small, reasonable decisions that are never revisited. A software subscription taken for a specific project continues billing long after the project ends. An insurance policy renews automatically each year without being tested against the market. A supplier agreement negotiated five years ago no longer reflects current volumes. Service contracts overlap. Memberships go unused.

Individually, these items rarely attract attention. Collectively, they can represent a meaningful percentage of overheads. A structured review, examining every recurring cost line by line and asking whether it still delivers value, routinely uncovers savings that drop straight to the bottom line. Unlike new sales, which carry costs of their own, a euro of eliminated waste is a euro of pure profit.

Understanding Costs Reveals True Profitability

A cost review does more than identify savings. It clarifies what the business actually earns from its work. Many SMEs allocate costs loosely, which distorts their understanding of which products, services and customers are genuinely profitable.

When costs are properly understood and allocated, the picture often changes. Services believed to be strong performers may be marginal once the full cost of delivering them is counted. Others may be quietly excellent. This knowledge is essential before growth, because expansion should concentrate on the areas where the business genuinely makes money. Growing an unprofitable service line simply produces more unprofitable activity, at greater scale and greater risk.

A Lean Cost Base Strengthens Funding Conversations

Growth frequently requires finance, whether through bank lending, grants or investment. Lenders and investors examine cost discipline closely. A business that can demonstrate a recently reviewed, well-controlled cost base presents as a stronger, lower-risk proposition than one whose overheads have drifted upwards unexamined.

A leaner cost base also improves the key figures that funders assess: margins, break-even point and cash generation. In many cases, the savings identified in a thorough review reduce the amount of external funding required in the first place, lowering both the cost and the risk of the growth plan.

How to Approach a Cost Base Review

An effective review is systematic rather than casual. Every recurring cost should be listed and questioned. Is it still needed? Is it competitively priced? Is it being fully used? Who is responsible for it? Contracts approaching renewal deserve particular attention, as do categories where markets have become more competitive, such as insurance, energy, telecoms and software.

The review should also look forward. Which costs will scale with growth and which will not? Understanding the difference between fixed and variable costs allows owners to model how profitability will behave as revenue increases, and to plan expansion with realistic expectations rather than hopeful ones.

For Irish SMEs preparing for their next stage of growth, a cost base review is one of the highest-value exercises available. It funds part of the growth itself, sharpens understanding of profitability, strengthens funding applications and ensures that expansion multiplies strength rather than waste. Ambition deserves solid foundations. Reviewing costs first is how a business builds them.
