The most common way a growing resale operation fails is not lack of profit. It is holding all the profit as clothing. Every euro earned goes into the next buy until there is a full rail, a good spreadsheet and no cash.
Profit is recognised when an item sells. Cash is what is in the account today. A month where you bought eighty items and sold sixty can be highly profitable and still leave you with less money than you started with — the difference is sitting on the rail, and the rail does not pay for the next bale.
This gap widens as you grow, because growth is funded by buying more than you sell. That is fine and normal, right up until an unexpected cost arrives and there is nothing liquid to meet it.
First: keep a reserve you do not source from. A fixed buffer that is simply not available for buying stock, however good the opportunity looks. Its whole purpose is to be there when something unplanned happens, and any reserve you are willing to raid for a good deal is not a reserve.
Second: cap your inventory in units, not euros. A euro cap drifts upward as you move into more expensive stock. A unit cap forces the real question — can I actually photograph, list and manage this many items? — and that constraint binds long before the money does.
Group inventory by how long it has been listed — under 30 days, 30 to 60, 60 to 90, and over 90. The shape of that distribution is the fastest health check available. A business in good order is heavily weighted to the first bucket; one in trouble has a growing tail.
The over-90 bucket needs a standing policy rather than case-by-case deliberation: bundle it, discount it hard, or write it off. Whatever you choose, decide it once and apply it automatically, because the alternative is a rail that only ever grows.
As much as you can list, photograph and manage properly, which is usually less than you can afford. Work backwards from your listing throughput per week and the time it takes stock to sell, rather than from your available cash.
Bundle it with items that do move, sell it on as a job lot, or donate it and take the loss cleanly. Holding it costs space, attention and the illusion that it is still an asset — none of which is free.
