A practical way to decide which slow-moving inventory deserves action.
Most retailers and dealers know they are carrying some slow-moving inventory. The harder part is deciding what to do about it.
An aging report can identify hundreds or thousands of items that have not sold recently. That is useful. But it creates a problem of its own: when everything on the report looks like an issue, it is difficult to know where to start.
The result is usually familiar. The report gets reviewed occasionally, a few obvious items get handled, and the larger problem stays exactly where it was.
Age matters. Dollars matter more.
Suppose you have two items. The first has not sold in 420 days. You have one on hand, and your investment is $32. The second has not sold in 230 days. You have nine on hand, and your investment is $2,100.
Sorted by age, the first item looks like the bigger problem.
From a cash standpoint, the second item is far more important. This is why an aging report is a starting point, not a decision.
Age is only one of the questions
When you review slow inventory, a handful of questions put age in context.
None of those questions tells you what to do on its own. Together they give you a much better picture than a date does.
Not all old inventory is bad inventory
Some slow-moving inventory belongs on the shelf. Service may need access to parts that sell infrequently. A seasonal product can go months without movement and still be exactly right to carry. You may stock an item on purpose because customers expect to find it, even though it does not turn quickly.
That is why labeling everything past a certain age as dead can mislead you. It is a judgment call — but better information makes the judgment easier.
There is a related situation that is easier to miss. Imagine an item that sells one or two units a year, and you have one on hand. That is probably reasonable. Now imagine the same item with seven on hand. The item is not the problem. The quantity is.
Or take an item that gets reordered every time one sells, even though current stock already represents several years of normal demand. That is not dead stock yet. But it is where next year’s dead stock is being created.
A good inventory review asks both questions: what has already gone stale, and where are we carrying more than the sales history supports? The second one gives you the chance to act before the money is stuck.
Start where action can matter
If your aging report has 2,000 lines on it, solving the whole list is not a realistic plan. Start by isolating the items where a decision could change something.
Instead of asking someone to work the dead-stock report, hand them a manageable group of items worth reviewing. Twenty meaningful decisions are usually worth more than staring at 2,000 lines.
Getting rid of it is not the only option
Once an item deserves attention, the next question is not automatically how to make it disappear. There are more choices than that, and the right one depends on the item.
That range of options is another reason a blanket age rule is rarely enough on its own.
This is really a cash question
Inventory sitting on a shelf is money. When it sells, that money comes back into the business and can go to work again. When it does not sell, the cash stays where it is.
That matters because the same dollars could be doing something else — faster-moving inventory, payroll, equipment, facility work, paying down borrowing, taking a buying opportunity, or simply creating some breathing room.
Which makes slow inventory more than a parts or purchasing issue. It is a financial issue for the whole business.
Where do we have meaningful dollars tied up in inventory that no longer matches the way we actually sell?
That question produces a far more useful conversation than “we need to clean up our dead stock.”
Age still matters. But now you are looking at age alongside quantity, investment, demand, and the role the item plays in the business. You are no longer trying to make an enormous report disappear. You are deciding where action makes the biggest difference — which is a much more practical place to start.

Applies across: Revenue and Executive — buying decides what you own, and what you own decides what your cash is doing.
