When a roastery stops growing, the explanation offered is usually about the market. Competition is fierce, customers are price-sensitive, the good accounts are taken. Sometimes that is true. More often, when you build the cash flow out month by month, the business was not short of demand at all. It ran out of cash at precisely the moment it was succeeding.
This is not unique to coffee, but coffee has an unusually severe version of it, and the severity is structural rather than circumstantial.
The timing, laid out plainly
Green coffee is paid for on or before shipment. If you are buying through an importer holding local stock you may get thirty days; if you are contracting at origin you are funding coffee that will not arrive for weeks and will not be sold for weeks after that.
Roasted coffee sold into B2B — cafés, hotels, offices, retail — is collected in sixty to ninety days. Hotel groups and larger retail chains frequently take longer, and they do not negotiate on this.
So the money goes out at the start of a cycle and comes back at the end of a much longer one. Between those two points, the business is funding the gap out of its own pocket. That gap is the working capital requirement, and it is not a one-off. It is permanent, and it grows in direct proportion to sales.
Why growth makes it worse, not better
This is the part that catches people, because it is counter-intuitive. A profitable business that doubles its sales does not generate twice the cash. In the year it doubles, it may generate no cash at all.
The reason is that the working capital requirement scales with revenue. Double the volume and you are holding roughly double the green, carrying roughly double the receivables, and funding both for the same number of days as before. The additional profit on the additional sales arrives later than the additional cash those sales consumed. In the intervening months the business is more profitable and less liquid than it was before.
Which produces the scenario I have seen more than once: an owner wins the account they have been chasing for two years, and six months later cannot pay for the green to service it. The business was never failing. It was succeeding faster than its balance sheet could carry.
The levers, in order of how much they move
There are only four, and they are not equally useful.
Collect sooner. The largest lever and the hardest one, because payment terms are usually set by the customer and the customers with the best volumes have the worst terms. Still worth attention: the difference between invoicing on delivery and invoicing at month-end is often two weeks of funding, and it costs nothing to fix. So does actually chasing. Most small operators have receivables sitting past terms that nobody has called about.
Hold less green for less time. Real, but limited, and it fights against the other economics. Buying smaller and more often improves cash and worsens price, freight and availability. There is an optimum and it is rarely where a cash-constrained owner is forced to sit.
Pay later. Supplier terms in green are a function of your size and your history. A small buyer has little leverage here, which is the uncomfortable truth about this particular lever: it is available in proportion to how much you already have.
Fund the gap. Facilities, trade finance, overdrafts. Available, priced according to the strength of the balance sheet, and therefore cheapest to those who need it least.
Three of those four levers work better the larger you are. That is not an accident, and it is the single most important structural fact about this industry.
What to actually build
If you take one thing from this: build a thirteen-week cash flow forecast, by week, and keep it current.
Not a profit and loss forecast. Not a budget. A week-by-week projection of cash in and cash out, with your green commitments and your expected collections in the weeks they will actually happen rather than the weeks you would like them to. It takes a day to build the first time and twenty minutes a week to maintain.
Nearly every owner I have worked with who did this discovered something they did not know. Usually that a specific month was going to be tight, three months before it became urgent — which is the difference between arranging something calmly and making a bad decision quickly.
Alongside it, two figures worth knowing and almost nobody tracks: your cash conversion cycle, which is how many days elapse between paying for green and collecting for the coffee it became, and your gross margin per kilo rather than in percentage terms. The first tells you how much cash any growth will consume. The second tells you whether the growth is worth consuming it for.
The honest conclusion
Most roasteries that stall are not badly run and do not have a demand problem. They have a structural funding requirement that grows with success and a set of levers that mostly favour scale.
Knowing that does not make it go away. But it changes what question you ask. Not "how do I sell more", which is usually the wrong constraint, but "what would it take to fund the volume I could already win" — and that is a question with a much smaller number of real answers.
