A distributor lives and dies on fill rate, so the instinct is to stock everything. The trouble is that most of the catalogue barely moves, and that is where the working capital quietly goes to sleep.

Ask a branch manager why a dead part is still on the shelf and the answer is almost always the same: a customer might need it, and a stockout on the wrong item loses the account. That instinct is not wrong. But followed blindly across tens of thousands of SKUs, it quietly builds one of the largest working-capital positions in the economy. US merchant wholesalers were sitting on around $964 billion of inventory in August 2026, and the sector's inventory-to-sales ratio hit 1.40 in late 2022, the highest sustained level since the 2008-09 crisis. A lot of that is long tail that will turn once or twice a year, if at all.
The core of the problem is intermittent demand. A huge share of an industrial catalogue sells in ones and twos, sporadically, with long gaps. Run a moving average over a part that sold three units all year and it rounds the forecast to roughly zero, so you either carry it on gut feel or you drop it and get burned by the one order that mattered. Classic forecasting was built for items that sell every week. It has very little to say about the item that sells every eighth month, which is most of the catalogue.
Even when demand is understood, the buy gets distorted. Minimum order quantities and vendor price breaks push you to take more than the next few months need, because the per-unit price looks better. On a fast mover that is fine. On a slow mover it is how a part ends up with eight years of coverage on the shelf, bought once to hit a price break and never fully sold.
The mistake distributors make under cash pressure is the across-the-board cut: trim every line by the same percentage. That guts the steady sellers that protect fill rate and barely touches the dead weight, so service falls while the real excess stays. The two goals, high fill rate and lean working capital, are both outputs of sizing each item correctly, not of a blanket policy applied to all of them at once.
The distributors who get the long tail under control do three things. They forecast intermittent demand with a method built for it, so slow movers are sized deliberately instead of guessed. They set safety stock and reorder points per SKU on real demand variability and lead time, and challenge the MOQ instead of accepting the coverage it forces. And they plan across branches, so a part sitting dead in one location can serve demand in another before anyone reorders it. That is the deterministic, auditable approach DemandIntel brings to industrial and MRO distributors, every reorder traceable to its logic, running on top of the ERP you already run.
Fill rate is the whole value proposition, so the instinct is to stock the full catalogue, including tens of thousands of slow-moving parts. Across that breadth it adds up fast, which is why the sector's inventory-to-sales ratio ran as high as 1.40 and wholesaler inventory sits near $964 billion.
Not with a moving average, which rounds sporadic demand toward zero. Intermittent demand needs a method built for lumpiness, so each slow mover is sized deliberately on its real pattern and lead time rather than carried on gut feel or dropped.
Size each item individually rather than cutting across the board. Blanket cuts trim the steady sellers that protect service and leave the real excess in place; per-SKU right-sizing releases the long-tail cash while holding, or improving, fill rate.
Yes. Planning across locations lets stock sitting idle in one branch serve demand in another before anyone reorders, which cuts network-wide excess without lowering local service.
A dead part kept 'just in case' is not insurance. It is a bet you already lost, sitting on a shelf, paid for in cash.
