Budget 2026: what it means for you and your business —

Profit Improvement & Benchmarking

In short

Very few owners know which of their customers, products or jobs actually make money — and most are genuinely surprised when they find out. We analyse profitability line by line, review your pricing and cost structure, benchmark you against your sector, and identify where margin is leaking. It is frequently the highest-return piece of work we do, because the answer usually costs nothing to act on.

Most businesses try to grow their way to better profits. Often the faster route is to stop doing the unprofitable work they are already doing — which requires knowing which work that is. The usual finding: a minority of customers generate the majority of profit, and a meaningful slice of the business is loss-making at the line level while looking fine in aggregate.

Which of my customers and products actually make money?

Aggregate gross margin hides an enormous amount. Broken down by customer, product, service line or job, the picture is almost always more uneven than expected — and frequently includes work that loses money once you properly allocate the time spent on it.

We rebuild your profitability from the transaction level up, allocating direct costs and, where it matters, the labour actually consumed. The output is a ranked list. It is usually uncomfortable reading, and it is usually actionable immediately.

Should I raise my prices?

Often, and by more than you think — but the question is where, not whether.

A 1% price increase typically delivers a far larger percentage increase in profit than a 1% increase in volume, because it drops almost entirely to the bottom line. Yet owners consistently reach for volume first, because it feels safer.

The risk is real but usually overstated: the customers most likely to leave over a price rise are frequently the ones who were least profitable anyway. We model the volume loss you could absorb and still be better off — which reframes the decision considerably.

Where does margin usually leak?

Scope creep — work done and never invoiced. Discounting — habitual, undocumented, and rarely reviewed. Under-recovered time — service businesses quoting on optimistic hours. Purchasing — supplier prices that have crept up unchallenged for years. Stock — obsolete, over-ordered, or written off quietly. Small customers — where the cost to serve exceeds the margin earned.

Each is dull. Together they are frequently the difference between a good year and a bad one.

How do I compare to others in my sector?

We benchmark your key ratios — gross margin, overhead as a percentage of turnover, staff cost ratio, debtor days, stock turn — against sector norms.

Benchmarking is not about being average. It is about spotting the ratio that is materially out of line and asking why. Sometimes there is a good reason. Often there isn’t, and that gap is your opportunity.

A 1% price rise usually beats a 1% volume rise

Price increases drop almost entirely to the bottom line; volume increases bring costs with them. Yet almost every owner reaches for volume first. Before you chase more work, it’s worth knowing whether the work you have is priced properly.

Frequently asked questions

How do I know which customers are profitable?

By rebuilding profitability from the transaction level, allocating direct costs and the labour actually consumed — not by looking at aggregate margin, which hides everything. The result is usually uneven, sometimes uncomfortable, and almost always immediately actionable.

Is it better to raise prices or increase volume?

Usually prices. A 1% price rise drops almost entirely to profit; a 1% volume rise brings costs with it. The customers most likely to leave over a price increase are often the least profitable ones anyway. We model how much volume you could afford to lose and still be better off.

What's the most common cause of margin leakage?

Scope creep — work done and never invoiced — closely followed by habitual discounting that nobody reviews, and under-recovered time in service businesses that quote on optimistic hours. Individually they're small. Together they're frequently the difference between a good year and a bad one.

How useful is benchmarking against my sector?

Useful for spotting ratios that are materially out of line — not for chasing the average. If your overhead ratio is ten points above your sector, that's a question worth asking. Sometimes there's a good reason; often there isn't, and the gap is your opportunity.
