A company grows twenty percent. Then twenty percent again. The founder does not feel richer. The bank balance is tighter than it was two years ago, payroll takes more attention than it used to, and every conversation about hiring now starts with a pause. Nothing is obviously wrong. Everything is slightly harder.
This is the most common condition we find in businesses between five and fifty million dollars, and it is almost never a revenue problem. It is a mix problem, and revenue growth is what conceals it.
Why aggregate margin lies
Most companies at this size track gross margin as a single number. That number is an average, and averages are very good at hiding their components. A firm with five service lines can hold a perfectly respectable blended margin while two of those lines lose money on every engagement, subsidized by the one line that has always worked.
Growth makes this worse rather than better. New revenue tends to arrive in the newest lines, because those are the ones being actively sold. If the new lines are the unprofitable ones, then every point of growth dilutes the blend a little further while the top line reports success. The founder sees revenue up and margin roughly flat, concludes that scale will fix it, and adds capacity to the thing that is losing money.
Cash pressure in a growing company is usually a mix problem wearing a collections problem’s clothing.
The three questions
There are three questions that will tell you whether you have this problem, and they take about a week of real work to answer properly.
First: which line is most profitable, and by how much? Not which is largest. Not which the team enjoys. Contribution margin by line, with delivery cost fully loaded, including the senior people who get pulled in when something goes wrong. Fully loaded is where most internal attempts at this fall apart, because the cost of the founder’s own time is almost never allocated anywhere.
Second: where is delivery capacity actually going? Compare the percentage of capacity each line consumes against the percentage of profit it produces. In a healthy business those two numbers are roughly proportional. In the businesses we are describing they are frequently inverted, with the largest share of the best people assigned to the worst work.
Third: what would happen if you stopped? Model the retirement of the weakest line honestly, including the revenue you would lose, the clients who would leave, and the capacity you would free. The answer is often that profit rises immediately and revenue falls by less than expected, because some of those clients buy something else instead.
What usually stops people
The obstacle is rarely analytical. It is that retiring a service line feels like a retreat, and founders who have spent a decade adding things find subtracting genuinely uncomfortable. Revenue is legible to everyone, including competitors, employees, and one’s own sense of progress. Margin is legible to almost no one outside the room.
The companies that resolve this do one thing consistently: they change what gets reported. Once the monthly package leads with contribution by line rather than revenue by client, the decisions tend to make themselves. Nobody keeps funding a line they can see losing money every month. The problem was never willingness. It was visibility.
