Seed-to-Sale Tracking in Illinois and Missouri: Metrc, Reporting Deadlines, Reconciliation, and Outages

Illinois moved to Metrc in 2025, and Missouri’s guidance names Metrc as its statewide system. Illinois’s supply-side tracking rules took effect May 1, 2026, Illinois dispensaries reconcile daily and need approval before adjusting inventory, and Missouri sets 24-hour and 3-hour reporting deadlines. The two states handle a system outage in opposite ways.

The state record is part of the license

Seed-to-sale tracking is not back-office bookkeeping in either state. In Illinois and Missouri, the state system is the official record of where every plant and package is, and a gap between that record and the room is a compliance problem even when no product is missing. Illinois moved from BioTrack to Metrc in 2025. The state’s transition timeline set June 17, 2025 for all licensees to be operating in Metrc and July 1, 2025 as the date Metrc became the official tracking system and BioTrack access ended. Missouri’s Division of Cannabis Regulation identifies Metrc as the statewide track-and-trace system in its 2023 guidance. Missouri’s rule refers to the “state-wide track and trace system” rather than to a vendor, so operators should confirm the current platform and integration requirements with the Division before changing software.

The rules that govern what goes into the system differ by state and, in Illinois, by regulator. The Department of Agriculture regulates cultivation centers, craft growers, infusers, and transporters. IDFPR regulates dispensaries. Missouri’s Division of Cannabis Regulation regulates all license types under one chapter of rules.

Illinois supply side: the Subpart K rules effective May 1, 2026

The Department of Agriculture’s Part 1300 rules, including Subpart K on the cannabis plant monitoring system, were added effective May 1, 2026 (50 Ill. Reg. 7050). Section 1300.1030 requires a licensee to record activities in the system upon completion of the activity. The listed activities include receiving product, rejecting a transfer, changing physical or chemical form or item category through extraction, distillation, infusion, or formulation, destroying or wasting product, packaging and repackaging, sales with the agreed price or value, harvests with the wet weight of each batch, movement within the facility, and plantings. For each activity, the licensee records the type of product, weight, volume, or count, the date, the unique serial number, and any conversion rate or formula (8 Ill. Adm. Code 1300.1030).

“Upon completion” is the operative deadline. A harvest, a transfer, or a waste event that is entered at the end of the week from paper notes does not meet it. Standard operating procedures should put the system entry inside the task, so the employee who weighs the harvest or seals the package records it before moving on.

Illinois dispensaries: daily reconciliation and approval before adjusting

The Cannabis Regulation and Tax Act requires each dispensary to maintain a real-time, web-based point-of-sale system accessible to IDFPR and an account in the State’s verification system recording each sale at the time it occurs, each day’s beginning inventory, acquisitions, sales, disposals, and ending inventory. On delivery, the dispensary must confirm that the product name, strain, weight, and identification number on the manifest match the label and package (410 ILCS 705/15-75(a)-(c)).

The agent-in-charge must conduct a daily inventory reconciliation confirming that the State’s system matches the point-of-sale system and the physical product. Department approval is required before any inventory adjustment, and adjustment documentation must be kept at the dispensary for two years (410 ILCS 705/15-75(d)(1)). IDFPR’s rule repeats those requirements and adds detail. If the cause of a mistake-based imbalance is not identified within two calendar days of discovery, the dispensary must inform the Department in writing, and it must complete the investigation within 10 business days or notify the Department of its next steps. Bulk product stored under the rule is verified daily and counted monthly (68 Ill. Adm. Code 1291.310).

An imbalance caused by theft or suspected criminal activity follows a separate path. The dispensary must notify IDFPR and the Illinois State Police in writing within 24 hours of first discovery (410 ILCS 705/15-75(d)(3)). Records must be kept for five years in a secure location at the dispensary (410 ILCS 705/15-75(e)).

Missouri: what 19 CSR 100-1.130 requires

Missouri’s rule makes the statewide track-and-trace system each licensee’s system of record and requires that product be traceable in it at all times, from seed or immature plant through sale, testing, or destruction. Immature plants at least eight inches tall or wide must be tagged, packaged product must bear a tag, and a new tag is required when product changes category or is incorporated into another product. Licensees enter each day’s beginning inventory, harvests, acquisitions, sales, disbursements, and other required data, and a record is incomplete unless all available fields are completed, including the responsible facility agent. Dispensary sales are recorded immediately (19 CSR 100-1.130(1)).

Missouri’s deadlines are short. A discrepancy may not be corrected through an inventory adjustment until it has been documented, investigated by management, and reported to the Department within 24 hours of discovery. Errors involving a consumer’s or patient’s purchase allotment must be reported and corrected within 24 hours of identification. Suspected criminal activity by a facility agent must be reported to the Department and to law enforcement within 24 hours. Licensees submit a monthly physical inventory report showing adjustments and reconciliation with the state system, and scales must be inspected at least monthly and recalibrated at least yearly. Records are kept for at least five years (19 CSR 100-1.130(1)). A licensee that fails to comply, or intentionally misuses or falsifies tracking data, may be fined up to $50,000 and have its license restricted, suspended, or revoked (19 CSR 100-1.130(2)).

The Division’s guidance explains what counts as a discrepancy. Moisture loss or gain within the expected range, and product designated for waste, are not discrepancies because the product can still be accounted for. An error where product is still accounted for, such as a wrong package selected at sale, is corrected immediately with a detailed note. Vague notes may themselves lead to a notice of violation (DCR guidance, Mar. 6, 2023).

When the tracking system goes down

The two states take opposite approaches to an outage, and a multistate operator’s procedures must reflect both.

In Illinois, the supply-side rule contemplates continued activity with careful records. During a loss of access, the licensee must keep comprehensive records of every activity required to be reported. It must report the loss to the Department no later than the end of the business day on which it is discovered, and within three business days after access is restored it must enter all activities that occurred during the outage. It must also document the cause of the outage and the dates and times access was lost and restored (8 Ill. Adm. Code 1300.1050).

In Missouri, the rule requires the licensee to stop. During a seed-to-sale system failure or loss of connection, the licensee must cease performing all actions required to be tracked. The failure must be reported to the Department within three hours, and once the system is restored, the licensee must confirm that all inventory and tracking information is accurately reflected (19 CSR 100-1.130(1)).

A single downtime procedure cannot serve both states. Missouri staff need clear authority to halt sales, transfers, harvests, and production. Illinois staff need a paper or offline log that captures the same data the system would, a single person responsible for entering the backlog, and a second person to verify it against the log and the physical inventory.

Design the workflow around reportable events

The most reliable way to reduce tracking errors is to list every event that changes legal inventory and assign each one an owner, a deadline, a source record, and a verification step. Propagation, plant movement, harvest, drying, production, packaging, sampling, testing, transfer, receipt, sale, return, waste, and destruction should each have a written workflow in which the system entry is a step, not an afterthought.

Transfers deserve particular care. Verify the destination license, create the manifest in the system before product moves, verify tags and quantities, authorize transport, and reconcile receipt. At the receiving end, Illinois dispensaries must match manifest, label, and package before accepting product.

Tags, conversions, and master data

Plant and package tags connect the physical product to the record. Control unused tags, assign them only through authorized processes, and document damaged or replaced tags. When product changes form through extraction, infusion, or repackaging, the production record should link outputs to inputs and record waste and the conversion rate or formula, which Illinois requires (8 Ill. Adm. Code 1300.1030) and Missouri supports through its rule that manufacturers reconcile raw material to finished product by process lot (19 CSR 100-1.130(1)).

Many errors begin with master data. Standardize product names, item categories, units of measure, recipes, waste reasons, and locations before employees use them. Missouri requires dispensary sales to be recorded in grams for flower, prerolls, and concentrates and in milligrams of THC for infused products, so unit setup is a compliance step.

Permissions, integrations, and internal audit

Limit system permissions to what each role requires, remove access promptly when employees leave or change roles, and prohibit shared credentials. A user who can create packages, adjust inventory, and approve exceptions without oversight can defeat otherwise strong procedures.

When point-of-sale, cultivation, manufacturing, or accounting software integrates with the state system, define which system is authoritative for each data element and how failed transmissions are detected. Daily exception reports should flag rejected transmissions, stale packages, negative quantities, duplicate identifiers, transfers open too long, and yields outside expected ranges.

Internal audit should trace complete chains. Pick a package and follow it from source through every transfer, conversion, test, sale, or destruction, comparing the electronic history with tags, manifests, batch records, invoices, and point-of-sale data. Then reverse the test by selecting physical inventory and proving that each item appears in the system under the correct identifier and location. Repeat the exercise for returns, failed tests, rejected transfers, and destruction.

Records that also serve tax and banking

The same records support the federal tax return and the bank’s review. Inventory counts that do not reconcile to the general ledger weaken the cost of goods sold figure on examination, and deposits that do not tie to recorded sales raise questions in transaction monitoring. Our briefings on section 280E and cannabis banking explain those uses.
