Shrinkage and write-offs

The stock that is never going to sell

Obsolete stock is the least urgent problem in any storeroom and one of the most expensive.

Every business accumulates it: items superseded, seasons missed, a bulk order that seemed sensible, a line discontinued by the customer who used it. It sits, it is counted, it occupies space, and it is on the balance sheet at a value it will never realise.

Juggling several suppliers or workstreams creates a prioritisation problem similar to handling multiple clients. For one approach to keeping parallel work visible, see further details.

Nothing forces a decision, which is precisely why it accumulates.

Define it by movement, not by feeling

A rule makes it visible: anything with no movement in twelve months, or with more than a stated period of cover at current demand.

Both figures come from the movement history. Without a rule, dead stock is identified only when someone notices it, which is when the shelf is full.

It is already a loss

The money was spent. Holding the stock does not preserve the value; it adds storage, counting and handling cost on top of a loss that has already happened.

For U.S. accounting context, IRS Publication 538 explains accounting methods and includes guidance relevant to inventories.

The options, in order of preference

  • Sell it at a discount. Recovers something and clears the space.
  • Return to supplier, where terms allow — worth checking, because more suppliers accept returns than businesses ask.
  • Use it: substitute into another product, use as a sample, as a spare part.
  • Donate it, where that has a tax treatment worth having in your jurisdiction.
  • Dispose of it and write it off.

The last is the least popular and is frequently the right answer once the holding cost is counted.

Discount early rather than deeply

Obsolescence is progressive: an item worth eighty percent of cost today is worth thirty in a year. The instinct is to hold out for a better price, and the value falls faster than the market improves.

A staged markdown policy — a defined discount at six months, a deeper one at twelve — takes the decision out of the moment and recovers more in total than waiting for the right buyer.

Review it quarterly with a decision required

The review only works if each item must receive an action. A list produced, discussed and left is a list that will be produced again next quarter with the same items on it.

Then ask how it got there

Dead stock is a symptom. The causes are a small set: over-ordering to hit a price break, a discontinued product not removed from the reorder list, a forecast that was wrong, or a customer relationship that ended without the stock being cleared.

Each is preventable and none is visible without looking back at how the items were bought. That review is worth more than the disposal itself.

General information. Nothing here is accounting, tax or legal advice. Stock valuation methods, write-off evidence requirements, the tax treatment of losses and the rules on monitoring staff differ substantially between jurisdictions and change over time. Take qualified advice on your own situation.

Deciding how much to order

The reorder point says when. Order quantity says how much, and it is usually set by whatever the supplier's price break happens to be.
