There are only five levers in a business that produce profit: leads, conversion rate, number of transactions, average sale value and margin. Every campaign, every hire, every price change works through one of them. Most owners spend the majority of their energy on the first, which is the hardest and most expensive of the five.
The value of the model is not the arithmetic, which is simple. It is what the arithmetic shows about small movements: five levers moved a little each, at the same time, do not add up. They multiply.
What is the model?
A chain that turns activity into profit. Leads multiplied by conversion rate gives you customers. Customers multiplied by number of transactions and by average sale value gives you revenue. Revenue multiplied by margin gives you profit.
Written as a line: leads × conversion × transactions × average sale × margin = profit.
Revenue and profit are not levers. They are outputs. Most owners watch the outputs monthly and have never written down the five numbers that produce them, which is why the response to a bad month is so often a general instruction to work harder.
Why do the levers multiply?
Take round numbers, chosen to show the arithmetic rather than to describe any particular business. A firm generates 1,000 enquiries a year and converts a quarter of them, so 250 customers. Each buys 2.4 times a year at an average of £800, which is £480,000 of revenue. At a 12 per cent net margin that is £57,600 of profit.
Now add ten per cent to each of the five. Leads become 1,100. Conversion becomes 27.5 per cent, so 302 customers. Transactions become 2.64 a year. Average sale becomes £880. Margin becomes 13.2 per cent. Revenue is 302 × 2.64 × £880, or roughly £702,000, and profit at 13.2 per cent is roughly £92,700 — a 61 per cent increase in profit from five changes that individually sound modest.
What do those ten per cents mean on the ground? A hundred more enquiries is about two a week. Conversion from 25 to 27.5 per cent means winning one more quote in forty. Average sale from £800 to £880 is one extra item, or a price review nobody notices. Margin from 12 to 13.2 per cent is one supplier renegotiated and one loss-making job declined. None of that is a transformation, and that is exactly the point: the transformation is in the multiplication, not in any single move.
What actually moves each lever?
Leads
A referral request built into the end of every job. One channel done properly rather than four done occasionally. Reactivating customers who have not bought for eighteen months, which is the cheapest source of leads in most businesses and the one nobody uses.
Conversion
Following up quotes, which most businesses do once or not at all. Quoting faster. Qualifying harder, so you stop writing proposals for people who were never going to buy.
Transactions
A reason to come back with a date attached: service plans, annual reviews, seasonal reminders. Or simply asking what else they need while you are already there.
Average sale
A better option alongside the standard one. Bundles. Removing the cheapest tier. Making sure the person quoting is not discounting to avoid an awkward moment.
Margin
Price, supplier terms, and job costing good enough to identify the work that loses money so you can stop doing it. Of the five this is usually the fastest to move and the one owners defer longest.
The honest caveat
The levers are not fully independent, and any model that pretends otherwise will get you into trouble. Push price hard and conversion usually falls. Push lead volume and lead quality tends to fall with it, so conversion drops. Push transactions with heavy promotion and margin drops.
That is not a reason to abandon the model. It is a reason to move one lever at a time, with a measure attached, and to watch what happens to its neighbours. If a five per cent price rise costs you two per cent of conversion you are comfortably ahead. If it costs you fifteen, you have learned something important about your market that no spreadsheet would have told you.
How to use it this month
- Write down your five numbers for last year. Estimate where you must, then go and find the real figure.
- Multiply them and check the answer against your accounts. If the chain does not reproduce your actual revenue, one of your numbers is wrong, and finding out which one is the exercise.
- Model ten per cent on each lever individually. Which single one produces the most profit for the least effort? For most businesses it is one of the two on the right.
- Pick the cheapest lever and run it for ninety days. One lever, one measure, one owner, everything else held still so you can read the result.
- Start tracking the numbers monthly — especially conversion, which almost nobody records and which is usually the fastest to move.
- Review the chain quarterly, then choose the next lever. Five levers, one at a time, is a two-year programme that changes what the business is worth.
The mistakes to watch for
Only ever pulling the first lever. More leads, more marketing, more enquiries — and then the same conversion rate applied to more of them. It is the most expensive route to the same profit, and it is popular because generating enquiries feels like doing something while raising prices feels like risking something.
The second is not knowing the five numbers at all. If you do not know your conversion rate you cannot tell whether the marketing was wasted or the quoting was, so you keep spending on the wrong one.
The third is moving all five at once. It looks efficient. It means that in ninety days you have no idea which change produced the result, so you cannot repeat it or defend it when it stops working.
The questions to sit with
- Out of 10, how confident are you in your conversion rate — and where would the number come from if you had to produce it today?
- Which of the five levers have you not touched in two years, and why that one?
- What would a ten per cent price rise actually cost you in lost work, and do you know that or are you assuming it?
- If you could move only one lever this year, which would you choose, and what does that choice say about where you are comfortable?
Revenue and profit are outputs, not levers. Write down the five numbers that produce them, move one at a time with a measure attached, and let the multiplication do the work.

Frequently asked questions
Which of the five levers should I move first?
Usually one of the two on the right, average sale or margin, because they apply to customers you already have and cost nothing but a decision and a conversation. Leads is the leftmost lever and the one everybody reaches for first, and it is also the slowest and most expensive to move, because you are paying to find strangers and then converting them at whatever rate you already convert at. The better sequence is to fix what happens to the enquiries you get before you buy more of them. Model ten per cent on each lever separately, and pick the one with the largest profit effect for the least disruption.
What if I do not know my conversion rate?
Then that is the first job, because without it you cannot tell whether a bad month came from the marketing or from the quoting, and you will keep spending on the wrong one. Start crudely: count the enquiries that arrived last month and the ones that became customers. A rough figure you review monthly beats a precise figure you never produce. Then check the whole chain against your accounts by multiplying your five numbers together. If the answer does not reproduce your actual revenue, one of the five is wrong, and finding out which one usually teaches you more than the model itself.
Does raising prices always reduce conversion?
Often, but by far less than owners fear, and the arithmetic usually still favours the rise. The levers are not independent, so a price increase does tend to cost some conversion, and the only honest way to find out how much in your market is to make the change with a measure attached and watch what happens over a quarter. What protects you is holding the number once you have set it: much of the damage owners attribute to a price rise actually comes from discounting it away in the meeting. Move one lever at a time so you can read the result rather than guess at it.
