The Six Mistakes That Sink Traders
The stories of traders who fail differ; their mistakes are identical. Working with traders for years, we saw the same six so often that we now use them as a checklist. They share one feature: none of them comes from market conditions.
The causal analysis sits in the year-one article; here are the mistakes and their antidotes. Everything around this stop is gathered in the complete guide.
Mistake 1: Buying a Large First Lot
Top of the list. A large first lot bought “to lower the unit cost” or because “the price was too good” is an investment in an unmeasured assumption. If the product does not turn as expected, all the capital stays on the shelf.
Antidote: the first lot is always a size whose loss will not stop you. If the minimum order exceeds that, find a second source or share the lot (sourcing guide).
Mistake 2: Buying in Cash, Selling on Terms
The second is the commonest cash killer: paying the supplier immediately and giving the customer 45 to 60 days. In between, the money is entirely outside and no new purchase is possible.
Antidote: work both ends — ask suppliers for terms and customers for deposits or take cash discounts. Credit is not free; it is priced (negotiation guide).
Mistake 3: Depending on One Customer and One Supplier
The third grows from comfort: while a customer or supplier works well, seeking alternatives feels like effort. But when that side changes prices, runs out of goods or changes direction, your negotiating power is zero.
Antidote: a second source for the main product and a ceiling on single-customer share — no more than a third of turnover. Treat it as the price of staying in business rather than a dent in profit.
Mistake 4: Not Measuring Stock
The fourth is silent: which product turned in how many days, which sat — unknown. When feeling manages, dead stock grows and eats an invisible share of capital. The result: good turnover, no cash.
Antidote: simple stock records and a monthly walk through storage. Anything past six months is turned into money, discounted if necessary (stock guide).
Mistake 5: Pricing from Cost
The fifth looks technical and lands heavily: adding a percentage to the purchase price. That calculation misses two things — the true cost (freight, waste, commission, shipping) and the market band.
Antidote: three-legged pricing — cost floor, competitor band, perceived value. Correct margin calculation sits in the margin guide; confusing margin with markup is this mistake’s sibling.
Mistake 6: Not Chasing Collection
The sixth loses the most money and is discussed least. The sale feels done; but in trade a sale completes when the money arrives. The trader who never reminds is the last one paid.
Antidote: a payment calendar, a polite reminder before the due date, and a clear stance on delay. A receivable with no late-payment clause is a receivable open to argument.
The Shared Pattern
Placed side by side, all six arrive at one result: being unable to make the next purchase. Trade ends when it stops, because its income is cyclical rather than one-off.
So the antidote to all six fits in one sentence: protect your freedom to move. Protect cash, diversify sources, measure stock, chase receivables.
Field Note
A trader opened his file with us after closing; five of the six were there. What pained him most: “I had thought the market was bad.” Yet in the same period two competitors in the same product had grown. The market was the same for everyone; the decisions were not.
Quick Summary
Six mistakes: a large first lot, buying in cash while selling on terms, single customer and supplier dependence, unmeasured stock, pricing from cost, and not chasing collection. All block the next purchase. One antidote: protect your freedom to move.

Sık Sorulan Sorular
They do; the second and sixth reappear especially during growth. Reopen the list at every growth step, not once a year.
If caught early, yes: clear stock, tighten terms, find a second source. Caught late, the options narrow.
The large first lot, because it amplifies the other five. Once capital is locked on a shelf, the means to correct anything else disappears.
