Profitable but broke: the cash frozen in components and work-in-progress

«On the report we were profitable, but the account was thin. I couldn't work out where the money went until I looked at the warehouse. Several hundred thousand sat there in components and half-built units. There was profit — but in the form of a shelf, not cash.»

This is a common trap in defence tech and any manufacturing. The company is profitable on paper but constantly short of cash. The cause isn't losses but that the money is frozen in inventory: you paid for components upfront, they sit for months as stock and work-in-progress, and become cash only once the finished unit is delivered and paid for. There is profit — it's just not in the form of money.

Where the money disappears

In manufacturing, cash goes through a long cycle: money turns into components, components into work-in-progress, that into finished units, units into a delivery, and only after payment does it come back as cash. At each stage the money is «stuck»: you can't pay salaries with it until the cycle closes. In defence tech this cycle is especially long — components are imported with prepayment, and government contracts pay after acceptance.

How much exactly is frozen

Let's count on a simple example.

$150,000 of profit exists, but in the form of inventory, not money in the account. That's why the owner sees profit on the report and an empty account at the same time. And the faster you ramp production, the more cash gets stuck in inventory — growth without control of working capital easily leads to a cash gap in a profitable business.

Why «buying a buffer» costs more than it seems

In defence tech the temptation to buy components with a large buffer is understandable: scarcity, long lead times, fear of stopping production. But every extra batch on the shelf is frozen cash that isn't working. $50,000 of components bought «just in case» half a year ahead is $50,000 you may be short of for next month's payroll. Balancing a buffer for continuity against free cash is one of a manufacturer's main financial decisions.

«Profit on paper and money in the account are different things. In manufacturing the difference between them sits in the warehouse. Until you see how much cash is frozen in inventory, you manage profit, not money.»

What it looks like in real life

You hear the problem in typical phrases. «The report says profit, but there's not enough for payroll — where does the money go?» «We bought components with a buffer so as not to stop, and now the till is thin.» «The warehouse is full, the account is empty.» «We're growing, but somehow there's less and less cash.» Each line is about a company that watches profit and can't see how much money sits in inventory.

How to see it for yourself

To manage cash you need to see not only profit but how much money is frozen in components, WIP and finished units. In Finmap you track purchase spend and cost by project, and cash movement separately from accrued profit. It becomes clear how much cash sits in inventory and how much is actually available, and decisions about buying components are made with free cash in view, not just production need.

A few tips

• Separate profit from cash: in manufacturing the difference between them almost always sits in inventory.
• Watch the amount of frozen money — components, WIP, finished units — not just profit.
• Don't buy more of a component buffer than free cash allows: scarcity is worse than downtime, but a cash gap is worse still.
• Shorten the cycle where you can: the faster you assemble and deliver, the faster money returns from inventory.
• Plan purchases against inflows so you don't freeze cash right before payroll.

Profit sitting in the warehouse doesn't pay salaries. In manufacturing, being profitable and having money are different tasks, solved by control of working capital. The moment you see how much cash is frozen in inventory, you stop wondering where the money goes and start managing it.
