A workshop can be profitable on paper and still go under. I have watched it happen more than once. The order was good, the margin was there — and yet there was no money to pay suppliers or wages. The problem was never the profit. It was timing.
Profit is not cash
This is the first hard lesson in business: profit and liquidity are two different things. An investment means you pay out first and get paid back later; financing is the opposite. Manufacturing lives on the investment side — you spend on materials and labour today and collect from the customer months later. You can be profitable for a whole year and still be unable to pay a bill on Tuesday. Liquidity, not profit, keeps the lights on.
What the liquidity gap is
Export manufacturing has a built-in rhythm: money out first, money in later. You pay the workshop and the raw materials on day zero. The customer in Germany pays 60 to 90 days after delivery. The window in between — where your money is gone but has not come back — is the liquidity gap. The wider it is, the more working capital you need just to stand still.
Why it kills good workshops
One large order can drain everything. Your capital is tied up in goods that are already made and shipped but not yet paid. You look successful — busy, growing, profitable — and you cannot make payroll. This is exactly when workshops take a bad loan, sell at a discount, or miss the next order. Not because the business is bad, but because nobody managed the gap.
Five levers to close the gap
Here is the toolkit, in the order I actually use it:
- Customer deposit. The number-one lever. Money from the customer costs you 0% interest. Ask for a deposit before production, and a larger payment when the bill of lading is ready.
- Match your cash in and out. Split what you pay the workshop (deposit / on shipment / balance) so it lines up with when the customer pays you. Done well, the gap can shrink close to zero — no borrowing needed.
- Sell the receivable. Once goods are shipped you hold an invoice. Discount it at the bank, or use factoring or forfaiting (the export version, without recourse) to get paid early.
- Letter of credit (L/C). The customer's bank guarantees payment; you get paid the moment you present documents, closing the gap instantly — and you can borrow against it. The real king of international trade.
- Overdraft or own capital. Use this only to cover short peaks. It is the most expensive money, not a strategy.
The early-payment discount trick nobody teaches you
A good supplier will quote two prices: a cash price and a credit price. Always ask for both. The gap between them is a hidden interest rate. Convert it to an annual rate:
If taking the credit price costs you 60–70% per year (and it usually does), then paying late is one of the most expensive loans on earth. Almost always: pay early, even with borrowed money, because the bank is cheaper than the hidden rate.
The insight that makes you money
A workshop that only wants cash now is not being irrational. Their internal cost of capital is sky-high — today's money is worth far more to them than next month's. That is an opportunity, not an annoyance. If your capital is cheaper and you can wait longer, you pay early to negotiate the base price down, and you keep the spread. Whoever has cheaper money and more patience earns from whoever is short of cash.
The takeaway
Manage timing, not just margin.
- Get the deposit
- Match your payments
- Price in the hidden discount
- Know your true cost of capital
Closing the liquidity gap is often the whole difference between a workshop that scales and one that quietly dies with a full order book.
