Inventory Reconciliation SOP
Daily physical counts, tracking system verification, variance investigation, and METRC/BioTrack reconciliation procedures
Critical Reconciliation Requirements
- • Daily reconciliation required for all cannabis inventory (flower, concentrates, edibles, vapes)
- • Physical inventory must match tracking system (METRC/BioTrack) exactly - zero tolerance for plant count discrepancies
- • Acceptable variance: ±3% by weight for processed products, 0% for plant count
- • All variances must be investigated and documented within 24 hours
- • Unexplained losses over 3% may trigger regulatory investigation
- • Maintain reconciliation records for 7 years (audit trail requirement)
Reconciliation Frequency by Product Type
High-Value & High-Risk Products
- Plants: All immature, vegetative, and flowering plants (count must match exactly)
- Cash: POS registers, safes, cash rooms
- Concentrates: Vape cartridges, dabs, oils (high theft risk)
- Edibles: Packaged edibles in retail inventory
Moderate-Risk Products
- Flower: Packaged flower in retail inventory
- Pre-Rolls: Finished pre-roll inventory
- Topicals & Tinctures: Lower theft risk products
Full Facility Inventory
- Complete Physical Count: All products, all locations, all stages
- Packaging Materials: Child-resistant packaging, labels, containers
- Waste: Cannabis waste awaiting disposal
Comprehensive Audit
- Third-Party Count: Independent auditor verifies inventory
- System Audit: Review all tracking system entries for accuracy
- Process Review: Evaluate reconciliation procedures and identify improvements
1Daily Reconciliation Procedures
End-of-Day Reconciliation (Retail/Dispensary)
Perform at close of business each day (typically 8pm-10pm):
- Step 1: Close all POS terminals and generate sales reports
- Step 2: Count cash in registers and safes (reconcile with POS totals)
- Step 3: Physical count of high-value products (concentrates, edibles)
- Step 4: Compare physical counts to tracking system inventory
- Step 5: Investigate any variances over acceptable limits
- Step 6: Document all counts and variances in reconciliation log
- Step 7: Update tracking system with any adjustments (if approved)
Daily Plant Count (Cultivation)
Perform during morning rounds (typically 8am-10am):
- Immature Plants: Count all plants in propagation/clone rooms
- Vegetative Plants: Count all plants in veg rooms (verify RFID tags)
- Flowering Plants: Count all plants in flower rooms (verify RFID tags)
- Destroyed Plants: Document any plants destroyed due to disease/males
- Tracking System: Verify counts match METRC/BioTrack exactly
- Zero Tolerance: Any plant count discrepancy must be resolved immediately
Two-Person Count Requirement
- All physical counts must be performed by two employees (dual verification)
- One person counts, second person verifies and records
- Both employees sign reconciliation log
- Employees should rotate counting duties (prevent collusion)
- Manager or supervisor must review and approve all reconciliations
2Physical Count Procedures
Count Preparation
- Schedule counts during low-activity periods (early morning or after close)
- Ensure all inventory is organized and properly labeled
- Print current inventory report from tracking system
- Prepare count sheets with product names, SKUs, and expected quantities
- Gather counting equipment (scales, barcode scanners, clipboards)
- Assign specific areas/products to each counting team
Counting Methods by Product Type
Plants (Count)
- Count each plant individually (no estimation)
- Verify RFID tag is present and readable
- Note any plants showing disease, stress, or hermaphroditism
- Document any missing tags or tag discrepancies
Flower (Weight)
- Weigh each package individually on calibrated scale
- Verify package tag matches physical product
- Check for damaged or opened packages
- Record batch numbers and expiration dates
Edibles & Concentrates (Unit Count)
- Count individual units (cartridges, gummies, chocolates)
- Verify packaging is intact and properly sealed
- Check expiration dates and remove expired products
- Scan barcodes to verify SKUs match physical products
Count Documentation
- Record all counts on standardized count sheets
- Include: date, time, location, product name, SKU, quantity, unit (count/weight)
- Note any discrepancies, damaged products, or quality issues
- Both counters sign and date each count sheet
- Photograph high-value inventory counts (recommended)
- Enter counts into inventory management system immediately
3Variance Investigation & Resolution
Acceptable Variance Thresholds
- Plant Count: 0% variance (must match exactly)
- Flower (by weight): ±3% variance acceptable (moisture loss, handling)
- Concentrates (by weight): ±2% variance acceptable
- Edibles (by unit): 0% variance (must match exactly)
- Cash: $0.00 variance (must balance exactly)
- Variances within acceptable limits require documentation but no investigation
- Variances exceeding limits require immediate investigation
Variance Investigation Steps
When variance exceeds acceptable limits:
- Step 1: Recount immediately (verify count accuracy)
- Step 2: Review tracking system entries for data entry errors
- Step 3: Check for unreported sales, transfers, or waste
- Step 4: Review security camera footage (if theft suspected)
- Step 5: Interview staff involved in handling product
- Step 6: Document investigation findings in variance report
- Step 7: Implement corrective actions to prevent recurrence
Common Variance Causes
Data Entry Errors (Most Common)
- Incorrect quantity entered in tracking system
- Wrong product SKU selected during sale or transfer
- Duplicate entries or missed entries
- Batch number transposition errors
Process Issues
- Unreported waste or product destruction
- Sampling not documented in tracking system
- Moisture loss exceeding expected range
- Product moved between locations without transfer documentation
Theft or Diversion (Serious)
- Employee theft (internal)
- Customer theft (external)
- Unauthorized removal of product
- Requires immediate law enforcement notification and state authority report
Variance Resolution
- If Error Found: Correct tracking system entry, document correction
- If Legitimate Loss: Create waste/loss entry in tracking system
- If Theft Suspected: File police report, notify state authority, conduct internal investigation
- If Unexplained: Document as unexplained loss, adjust inventory, report to state if required
- All variance resolutions must be approved by manager or owner
- Maintain variance investigation reports for 7 years
4METRC/BioTrack System Reconciliation
Daily System Verification
- Log into METRC/BioTrack and generate current inventory report
- Compare system inventory to physical count results
- Verify all sales, transfers, and waste entries from previous day are recorded
- Check for any pending transfers or unresolved discrepancies
- Confirm all package tags are active and properly assigned
- Review system error messages and resolve immediately
Common System Discrepancies
- Pending Transfers: Transfers sent but not yet accepted by recipient
- Rejected Transfers: Transfers rejected due to discrepancies (investigate immediately)
- Inactive Tags: Package tags deactivated but product still in inventory
- Duplicate Tags: Same tag assigned to multiple packages (system error)
- Missing Tags: Physical product has no tag in system
- Sync Errors: POS system not syncing with METRC/BioTrack (check API connection)
System Adjustment Procedures
When adjustments are necessary:
- Document reason for adjustment in variance report
- Obtain manager approval before making adjustment
- Use appropriate adjustment type in tracking system (waste, loss, correction)
- Include detailed notes explaining adjustment
- Retain supporting documentation (count sheets, photos, investigation reports)
- Some states require notification for adjustments over certain thresholds
5Monthly Full Physical Inventory
Planning & Preparation

- Print comprehensive inventory report from tracking system
- Assign counting teams and specific areas
- Prepare count sheets, scales, scanners, and other equipment
Count Execution
- Count all products in all locations (retail, storage, processing, waste)
- Use two-person teams for all counts
- Count systematically (left to right, top to bottom) to avoid missing items
- Mark counted items with stickers or tags to prevent double-counting
- Document any damaged, expired, or quality-issue products
- Take photos of high-value inventory counts
- Typical duration: 4-8 hours depending on facility size
Post-Count Reconciliation
