How Can a Tool Room See How Much Cash Is Tied Up in Unfinished Jobs?

A tool room can see how much cash is tied up in unfinished jobs by tracking its work-in-progress (WIP) — the total cost invested so far in every open job that has not yet been completed and paid for — in one continuously updated view. Work-in-progress in a tool room is the money already spent on material, machine time, and labour for moulds and dies still being built, plus completed jobs that have not yet been invoiced or fully paid. Seeing this clearly turns a vague sense of “cash is tight” into a specific, manageable number.

This matters because toolmaking ties up large amounts of cash for long periods: each bespoke job is financed by the tool room for the weeks or months of its build, before the customer’s final payment arrives.

What “cash tied up in unfinished jobs” actually includes

Cost invested in open jobs — material, machining, design, and labour spent so far on each tool still in progress.

Completed but uninvoiced jobs — finished tools that have not yet been billed.

Overdue final payments — staged or final payments held back past the agreed date, often pending customer approval.

Long-open jobs — projects that have been open longer than normal, quietly absorbing cash.

Why the number is usually unknown

The information needed to total this up is scattered: amounts spent per job sit across material purchases, machine and labour records, and job files; job status sits in schedules or in people’s heads; overdue payments sit in receivables. Because no single place adds it all up, most owners carry only a rough gut feel for their WIP — which is almost always lower than the real figure, with cash trapped in places they have forgotten about.

What seeing it clearly enables

When work-in-progress is visible in one place, an owner can take specific actions to free up cash:

Invoice completed jobs immediately instead of letting finished tools sit unbilled.

Chase overdue final payments while the customer relationship is still warm.

Investigate jobs open too long to find and clear what is stalling them.

Plan capacity and purchasing with a true picture of available working capital.

How it is done

To track WIP and trapped cash continuously, a tool room uses a system that connects to its job-costing, machine, material, and accounting data, totals the cost invested in each open job, and flags completed-but-unbilled jobs and overdue payments. This is the kind of capability a CEO intelligence layer provides — assembling the real position across systems into one live view, rather than a manual calculation done occasionally.

For a tool room, seeing trapped cash clearly is not just reassurance: freed working capital is what funds the next job’s material, allows the shop to take on more work, and reduces the constant cash strain of financing bespoke builds. The money is usually recoverable — but only if the owner can see where it is tied up in time to act.
