An eighth of flower that has been sitting on a New Jersey shelf for sixty days is worth about three quarters of what your menu says it is worth. The product is fine. The price is not.
Nobody approved that. There was no meeting, no markdown authorization, no line in the weekly numbers that read reduce this by twenty-five percent. It happened quietly, over nine weeks, while everyone was busy running the store.
Here is where owners misfile the problem. They treat slow stock as a merchandising mistake - wrong brand, wrong buy, wrong shelf. It is a working capital problem wearing a merchandising costume. Every jar that does not move is cash you already spent, standing still, in an industry where borrowing more is expensive. And it surfaces in the first number a buyer's analyst builds from your data: inventory turns.
Five decisions put that eighth where it is. Not one of them was made this week.
The purchase order you wrote six weeks ago
The common operating guidance is to buy about one month of supply, and to check it with one piece of arithmetic: inventory multiplied by thirty, divided by projected monthly sales. That is your days of inventory. Cova's retail guidance puts a healthy cannabis turnover benchmark at six to twelve turns a year, which is thirty to sixty days of stock on hand.
If that calculation comes back at ninety, you did not buy inventory. You bought a quarter of a year of a product whose price falls every week, and you paid for it up front, because cannabis vendor terms in New Jersey still run on cash or near-cash.
Became expensive: day 34.
The shelf space you gave it
Retail inventory sorts into three tiers: primary product sold exactly as it arrived, secondary product prepared on site such as pre-rolls and infused items, and tertiary accessories. Layer the standard ABC read over the top - A for the fast movers you watch weekly, B for the steady middle, C for the slow tail you stock thin or cut.
The cruel pattern is that the SKU in the worst position is very often the one you bought the deepest, because the buy and the merchandising decision were made by different people on different days and never reconciled. Nothing on the floor tells you that. Only the report does.
Became expensive: day 3.
The count you ran on a Saturday instead of a Monday
Weekly cycle counts on a rolling schedule - a different section of the store on a different day - beat a monthly all-hands count on every measure that matters, including the one New Jersey cares about. The operating KPI used across cannabis retail is an inventory discrepancy rate under one percent. Above that, you are not counting, you are discovering.
New Jersey's inventory rules also give you a very short window to reconcile and report a discrepancy once you find one. I walked through what actually goes missing in an earlier piece on shrink. This is the other half: not what left, but what never did.
Became expensive: day 21.
The aging report nobody opened
Every serious cannabis POS flags stock at thirty, sixty and ninety days. Two markdown ladders circulate, and they measure different clocks. The age ladder discounts roughly twenty percent at a month old and forty percent at two. The expiration ladder is tighter: fifteen percent at sixty days to expiry, twenty at forty-five, twenty-five at thirty, fifty at fifteen.
Argue with the exact percentages if you like. The thing to take from both is structural, and it is the whole point of this piece: the discount is a schedule, not a decision. Your only real choice is whether you set it deliberately on week four or absorb it accidentally on week nine.
Became expensive: day 45.
The discount you finally authorized at the register
You are not discounting into a calm market. Across tracked US markets, discounting ran from 23.6 percent to 27.1 percent of shelf value over the twelve months to September 2026, and dispensary retail gross margin has slid from about 52.6 percent in 2021 to 42.7 percent in 2025. The average New Jersey item sold for $29.10 in September, down from $31.57 a year earlier; the per-gram side of that is in last week's piece.
And the markdown lands in the worst possible place. Your product cost is already fixed and already sitting in cost of goods. Every dollar you give back at the register comes off gross profit - the only part that pays rent, payroll and the tax bill. How any of that is treated on a return is a question for your CPA, not for me, and 280E makes it a question worth paying for.
Became expensive: day 61.
- Daily. Receiving reconciliation against the manifest, before anything reaches a shelf.
- Weekly. Cycle count on a rolling section schedule, and the aging report read by a human, not just generated.
- Weekly. Days of inventory by category - inventory times thirty, divided by projected monthly sales.
- Monthly. Discrepancy rate against the one percent line, trended rather than taken as a snapshot.
- Quarterly. Assortment, reorder thresholds and vendor terms, with the bottom tail actually cut.
The decision the state already made for you
If nothing moves it, it does not quietly become a write-off. It becomes a regulated disposal event with its own paperwork. Under N.J.A.C. 17:30-9.14, unusable, returned, recalled or expired cannabis is either incinerated at a facility authorized by the Department of Environmental Protection, or rendered unrecoverable - finely ground and mixed with non-toxic biodegradable material until at least half the volume is not cannabis, held in a secure locked area in view of a camera. You weigh it and update inventory first. You keep a written record. You notify the Commission in writing, within ten business days, of the amount, form, weight and quantity destroyed.
Read the five days above again and notice they are out of order. The decisions were made in sequence; they became expensive in whatever order the shelf decided. That is why a buyer's team never asks how you buy - they build turns by SKU out of your own export and read the answer. It is the same exercise as how a dispensary gets priced, one level down. To see what the discipline is worth in a real asking price, read the current listings.
I have never once had a buyer ask an owner to explain their purchasing philosophy. They pull the inventory export and look at how long things sit, because that single number tells them what the owner's attention is actually spent on. A store turning stock eight times a year and a store turning it four times a year can post the same top line and sell for very different money.
The flower on your shelf is not spoiling. Your margin is. One of those you can see on a report every Monday morning.
