Inventory shrinkage is the silent killer of dispensary margins. While retail averages 1.4 percent shrinkage, cannabis dispensaries routinely see 2 to 5 percent — and some operators we have worked with have seen double digits before fixing their systems. At a $5 million annual revenue shop with 25 percent margins, 3 percent shrinkage costs $37,500 in lost profit every year. This guide breaks down where shrinkage comes from and the systems that prevent it.
The five sources of shrinkage
1. Theft
Both external and internal theft contribute to shrinkage. External theft includes grab-and-runs and organized retail crime. Internal theft is often subtler: a budtender giving friends extra weight, pocketing cash from off-book sales, or manipulating waste logs.
2. Administrative error
Mis-scanned products, incorrect unit conversions, and manual entry mistakes are the most common cause of shrinkage. A budtender who scans an eighth as a gram, or a manager who counts pre-rolls by the jar instead of by the unit, creates phantom inventory that is impossible to reconcile.
3. Waste and spoilage
Damaged product, expired edibles, and trim loss all contribute to shrinkage. The problem is not the waste itself — waste is inevitable. The problem is unrecorded waste that creates a gap between your physical count and your system count.
4. Vendor fraud
Short counts from wholesale suppliers are more common than most operators want to admit. A cultivator who ships 95 units but invoices for 100 creates a 5 percent shrinkage event before the product ever hits your shelf.
5. System sync errors
When your POS and your state traceability system drift out of sync, you get phantom inventory. A sale that registers in your POS but fails to report to METRC leaves the product "available" in METRC but gone from your shelf.
Prevention systems that work
- Daily cycle counts by category, not just monthly full counts.
- Dual verification for all waste disposal: two employees sign, two weigh.
- Barcode scanning at every touchpoint: receiving, stocking, sale, waste.
- Real-time METRC sync with discrepancy alerts within 15 minutes.
- Variance reporting: flag any category with over 1 percent drift weekly.
Reconciliation as a habit
The shops with the lowest shrinkage do not reconcile monthly. They reconcile continuously. Every shift change includes a quick count of high-value items. Every day ends with a variance report. Every week includes a deep dive into any category that drifted more than 1 percent. It is work, but it is cheaper than losing 3 percent of your inventory.
