Growth & margin
Revenue is growing. Why isn't profit?
More revenue only improves profit when enough remains after direct costs and the spending needed to run the business. If margin falls or overhead rises faster than gross profit, sales can grow while profit goes backwards.

How 20% more sales can leave 40% less profit
This simplified, hypothetical example compares two equal periods. Gross profit is revenue after direct costs. Operating profit here is gross profit less operating expenses, before interest and tax.
| Measure | Period 1 | Period 2 |
|---|---|---|
| Revenue | £100,000 | £120,000 |
| Gross margin | 40% | 35% |
| Gross profit | £40,000 | £42,000 |
| Operating expenses | £30,000 | £36,000 |
| Operating profit | £10,000 | £6,000 |
The extra £20,000 of sales creates just £2,000 of extra gross profit. Operating expenses rise by £6,000, so operating profit falls by £4,000. Looking only at sales would hide both causes.
Five checks before you add another growth target
1. Is each sale leaving enough behind?
Compare selling prices with direct costs over the same period. Include discounts, credits and the costs of delivering that work. A larger order book can bring less benefit if prices fall or fulfilment becomes more expensive.
Ask: what changed in gross margin, and which products, customers or projects explain it?
2. Has the mix of work changed?
Your overall margin can fall even when the margin on each product stays the same. Selling more of a lower-margin line changes the result. Look at the contribution from each stream, alongside the work and resources it consumes.
Ask: are we growing the parts of the business that create the return we want?
3. What did it cost to win the extra revenue?
Compare the extra commercial output with sales and marketing spending. Allow for your sales cycle: spending this month may support future revenue. Keep bookings and recognised revenue distinct so timing does not create a misleading comparison.
Ask: is the sales investment producing enough profitable work over the right time horizon?
4. Has overhead grown ahead of the business?
Hiring, premises and systems can add costs before new capacity produces a return. Separate deliberate investment from recurring overhead that is growing without a clear purpose. Across periods, use the same cost definitions and account for one-off items.
Ask: what output should the extra cost produce, and when should we see it?
5. Are we replacing lost business before we can grow?
A busy sales team may be replacing customers or contracts that have left. Look at retained revenue, lost customers and repeat purchases alongside new wins. The right next move may be improving retention or delivery before increasing acquisition spend.
Ask: how much new business is simply replacing what we lost?
Profit and cash need different checks
If reported profit looks healthy but the bank balance does not, check customer payment timing, stock purchases, supplier terms, tax and debt repayments. A profit problem and a cash timing problem can coexist, but the same action will not always solve both.
