Reading slow stock turn as trapped cash

The signal

For any client holding inventory, stock is cash in another form — money already spent that has not yet converted back. The warning sign is a stock-turn ratio that is slowing: inventory taking longer to sell through than it did a year ago, or stock balances climbing faster than sales. Each extra day of stock on hand is another day's cash sitting idle on a shelf.

It often creeps up unnoticed because, unlike an overdue invoice, slow stock does not chase itself into your attention. It simply accumulates.

What it means

Slowing stock turn ties up working capital exactly where it is least visible. Cash that should be circulating — bought, sold, collected, reinvested — is instead parked in goods that are not moving. If demand has genuinely softened, some of that stock may be heading for obsolescence and a write-down, turning a cash problem into a profit one as well.

It rarely travels alone. A business with slowing stock turn often also has lengthening debtor days, because the same demand softness that slows sell-through also slows payment. Read together, the two confirm a broad working-capital squeeze rather than an isolated inventory blip.

Run the play (steps)

1. Compare stock-turn days now against a year ago — direction matters more than the absolute figure.
2. Watch whether stock balances are growing faster than sales.
3. Identify slow-moving or ageing lines that may need clearing before they are written down.
4. Put stock turn alongside debtor days to see the full working-capital picture.
5. Free cash from the fastest lever first — usually receivables, then ageing stock.

What to say to the client

Make the idle cash visible: "You've got more stock on the shelf than a year ago and it's moving slower — that's cash sitting still. And your invoices are slowing too. Let's free up the easy cash first."

Since receivables usually release cash faster than discounting stock, point the client to a free debt appraisal so the quickest working-capital win is captured while the stock position is worked through.

When to bring in Merion

While the stock side is the client's own to manage, the receivables side often is not. When slowing stock turn comes paired with an overdue debtor book, escalate the debtors first — recovering them frees cash faster than clearing inventory. This is general information, not tailored financial advice.
