Why Inventory Accounting Is Different for Cannabis
In most retail businesses, inventory accounting is a matter of counting units and applying a costing method. Nevada cannabis inventory accounting has an additional, non-negotiable layer: every package, from seed or clone through final retail unit, must be tracked in METRC, the state's seed-to-sale system, and the accounting records must tie to that system rather than the other way around. If the general ledger and METRC disagree, METRC is the record the CCB and Department of Taxation will trust first.
The Package-Level Reconciliation Process
A proper inventory reconciliation matches every METRC package ID to a corresponding cost basis in the accounting system, tracking the package through cultivation, harvest, processing into multiple derivative packages, and eventual sale or transfer. This is meaningfully more complex than standard retail inventory tracking because a single cultivation batch can split into dozens of downstream packages with different product forms (flower, trim, extract) that each need their own allocated cost basis.
- Match every METRC package ID to a general ledger cost basis
- Track cost allocation through harvest splits and processing conversions
- Reconcile ending METRC on-hand quantities to the balance sheet inventory account monthly
Investigating Variances Between METRC and the Books
When METRC quantities and accounting records diverge, the investigation needs to happen the month the variance appears, not at year end when the trail has gone cold. Common causes include unrecorded waste entries, timing differences between a physical count and a METRC package adjustment, theft or diversion, and simple data entry errors when a package is split or combined. Each cause has a different remediation, so a generic write-off without investigation is both a weak internal control and a red flag if a CCB compliance review later asks how the variance was resolved.
A documented variance investigation should include the date the discrepancy was identified, the METRC package IDs involved, the dollar and unit amount of the variance, the root cause determined, and the corrective entry made. Retaining this documentation for every material variance builds a defensible history if the Department of Taxation or CCB ever questions inventory accuracy during a review.
Inventory Valuation Methodology
Cultivators generally need a costing methodology that captures direct materials, direct labor, and an allocable share of facility overhead under Section 263A as product moves through vegetative, flowering, harvest, drying, and curing stages, with cost typically accumulated by batch and then allocated across the packages that result from a harvest split. Retailers, by contrast, generally carry inventory at purchase cost from the wholesale supplier, since resellers are not subject to the same expansive overhead capitalization rules as producers.
- Cultivators: batch costing with allocation across harvest-split packages
- Retailers: purchase-cost basis from wholesale invoices
- Consistent method applied period over period, changed only with documented justification
Shrinkage, Waste, and Destruction Documentation
Cannabis waste and destruction have specific METRC recording requirements, and the accounting entries tied to those events need equally specific support: a witnessed destruction log, the METRC waste record, and the dollar value removed from inventory. Because waste is a routine part of cultivation (trim, non-viable clones, failed testing batches), a Nevada operator should expect a predictable pattern of waste as a percentage of production, and should investigate any period where that percentage moves meaningfully without an obvious cause.
Physical Counts and Cycle Counting
Beyond the perpetual METRC-based tracking, periodic physical counts remain essential, particularly at retail locations where product moves quickly and small discrepancies can accumulate unnoticed. A cycle count program that rotates through product categories weekly, combined with a full physical count at fiscal year end, catches discrepancies faster than relying on annual counts alone. This inventory discipline connects directly to the broader bookkeeping habits described in our nevada-cannabis-bookkeeping-guide and feeds the balance sheet accuracy covered in the nevada-financial-reporting-guide.
