Why Can a Business Lose More Money as Revenue Grows?

It sounds contradictory: every sale is profitable, product pricing is right, yet as the business grows, so does the cash squeeze. This situation has a name — “overtrading” — and it describes how the time gap between profit and cash grows exponentially with the rate of growth. This article focuses on the mechanism itself, that is, on why growth is a risk item in its own right.
What is overtrading and how does it happen?
Overtrading is when a business keeps growing without the working capital to support its sales volume. Even if every sale is profitable, it takes time for that profit to turn into cash; as growth accelerates, the capital needed to close this time gap also grows. If capital cannot keep up with this growth, the business can become unable to pay its bills even though it is profitable.
The mechanism with a concrete example
| Month | Monthly sales | Required stock investment | Settlements collected so far |
|---|---|---|---|
| 1 | 40,000 TL | 25,000 TL | 0 TL (not yet received) |
| 2 | 60,000 TL | 38,000 TL | 34,000 TL (month 1 settlement) |
| 3 | 90,000 TL | 57,000 TL | 51,000 TL (month 2 settlement) |
Sales grow every month, and every sale is profitable. But each month the required stock investment grows faster than the settlements collected up to that point. The gap widens a little every month — a gap that arises not because the business is failing but, on the contrary, because it is growing too fast.
Why is this a risk hidden inside “success”?
The most dangerous aspect of overtrading is that from the outside (and often from the inside) it gives the impression that the business is doing very well. Sales are rising, products are selling out, customer demand is strong — all the visible signals are positive. The problem shows up only in the bank account, and it is usually postponed with “it will sort itself out when the next settlement arrives”. But as long as growth continues, the gap does not close; on the contrary, it keeps widening.
What growth rate is safe?
There is no definite threshold, because it depends on the business’s cash conversion cycle (the concept we covered in the working capital article). A business with a short cash conversion cycle (fast inventory turnover, short settlement terms) can grow much faster, because capital comes back quickly and becomes usable again. For a business with a long cycle, the same growth rate can be dangerous.
Three ways to prevent overtrading
The first is to limit the growth rate to cash capacity — that is, to proceed not with the logic “there is demand, so I’ll grow” but with “there is demand AND I have the capital to meet it, so I’ll grow”. The second is to build a cash buffer before growing; this buffer closes the gap in the first few months of accelerating growth. The third is to deliberately brake the growth rate if necessary — for example, when a campaign invitation arrives and current capital cannot handle it, to decline the invitation partly or completely. This third option may seem counterintuitive, but it is safer than growing out of control and ending up on the brink of bankruptcy.
Does this risk apply equally to every business?
No. In businesses that operate without stock or produce on order, the risk of overtrading is much smaller, because growth does not require additional capital tied up in stock. The risk is seen most in combinations that require high stock investment and have long settlement terms — exactly the profile of a typical marketplace seller.
Declining a campaign invitation: a decision in numbers
The marketplace invites you to a big campaign, with an estimated demand increase of 150%. Current monthly sales are 50,000 TL, and the additional stock investment needed for the campaign is 45,000 TL. Free cash in hand is only 20,000 TL. Joining the campaign fully creates a gap of 25,000 TL — a gap that has to be closed with a credit card or supplier debt, with interest/term costs added on top. Partial participation with only the two best-selling products, on the other hand, captures part of the same opportunity while reducing the gap to 8,000 TL — a level that can be covered with the cash in hand. The “join fully or not at all” dilemma is false; partial participation is usually the overlooked third option.
Why the cash cycle of a small seller and a growing seller grows differently
For a small seller working at low volume, the delay in the cash conversion cycle is small in absolute TL terms and usually tolerable. The same percentage growth rate creates a much larger absolute TL gap in a business whose volume has grown — because the gap grows not as a percentage of revenue but together with revenue itself. That is why the risk of overtrading increases with size, and a growing business needs to monitor its growth rate much more closely than a business that is just starting out.
The moment commission is deducted also affects the cash cycle
On most marketplaces, commission is deducted directly from the sales amount when the settlement is created — so the seller does not pay commission separately but collects the net settlement. At first glance this seems to make cash management easier, but when growth accelerates it can turn into a trap: if the seller plans the budget for stock purchases based on the full sales amount (before commission), the lower settlement actually received will not cover this plan and the gap grows.
Checklist
- Over the last few months, as sales grew, did your bank balance grow proportionally, or did it shrink?
- Do you know your cash conversion cycle and plan your growth rate accordingly?
- Do you have a separate cash buffer before growing?
- Are you prepared to decline a demand increase/campaign invitation you cannot handle?
