What Is METRC: Cannabis Compliance Tracking Explained
What Is METRC and Why Does It Matter for Dispensaries?
METRC is a web-based inventory system that uses RFID (radio frequency identification) technology and serialized tags on each plant and package. Those tags let the system track cannabis from cultivation through the point of sale. States require licensed cannabis businesses to use METRC or a similar tracking system. That system gives regulators a rigorous way to oversee the cultivation, processing and sale of cannabis products.
Licensed operators across the United States run into METRC first in state regulations, then again in a software demo. Neither explains how it touches their actual work at the counter or during delivery.
What METRC Tracks From Seed to Sale
METRC logs every stage of a plant's life: cultivation, processing, packaging and the final retail sale. Illinois's state regulator describes using the system to monitor cannabis products throughout the entire supply chain. Illinois law also requires a Metrc RFID tag on every plant and package as part of that track-and-trace system. The Illinois Cannabis Regulation METRC overview explains that state's program, though each state regulator runs its own.
Where METRC Touches Your Daily Dispensary Work
Most explanations of METRC stop at the definition and never show how the system reaches into a dispensary's actual checkout and inventory software. For a licensed operator, METRC shows up in four places every day:
- Package intake. Compliance features built into a cannabis POS platform include METRC package intake, matching incoming products against their METRC record before they reach the shelf.
- Purchase limit enforcement. The same compliance features check each sale against state purchase limits at checkout before it completes.
- Sales delivery manifests. METRC sales delivery manifests are generated for products leaving the store, whether for pickup or delivery.
- Inventory adjustments. Inventory adjustments, such as damaged or returned product, sync back to METRC so the record matches what is on the shelf.
A cannabis POS platform with compliant checkout and real-time inventory ties these four touchpoints directly into daily work. See the cannabis POS software page and its METRC compliance features page for the full feature list.
Why Product Intake Depends on METRC Tags
A METRC tag is the serialized tag METRC applies to a plant or package, tracked by RFID from cultivation through the point of sale. Every plant and package carries one of these METRC tags for as long as it exists in the system.
Package intake in a cannabis POS platform depends on this tag: the software checks the physical package's METRC tag against its METRC record before accepting the inventory. Without a matching tag, the package cannot move into sellable inventory. For dispensary operations, this tag is the detail METRC relies on for every plant and package in the state's system.
METRC Compared to BioTrack and Leaf Data in Other States
METRC is not the only state-mandated tracking system. A cannabis POS platform's own FAQ confirms integrations with METRC, BioTrack, Leaf Data and other state-mandated seed-to-sale systems. Which one applies depends on the state.
California requires it too. The state's Department of Cannabis Control partners with Metrc to run the mandatory California Cannabis Track-And-Trace system, which every licensee must use. New York set December 17, 2025 as the deadline for every licensee to be credentialed in Metrc. California's Department of Cannabis Control and New York's Office of Cannabis Management both cover these requirements on their sites.
Washington State shows how this varies: it moved off the Leaf Data Systems platform and now runs its own in-house Cannabis Central Reporting System instead of METRC. Washington's Liquor and Cannabis Board explains the switch. Oregon, by contrast, requires every cannabis licensee and employee to use its METRC-based tracking system, and staff must complete METRC-provided training and pass a test before they get system access. Oregon's Liquor and Cannabis Commission covers that training requirement.
Operators should check their own state regulator to confirm which system applies, rather than assuming METRC is always the one in use.
Where Manual METRC Entry Breaks Down and What Synced Software Changes
Entering these workflows into METRC by hand creates a separate record from the point of sale, and the two records can drift apart. When that happens, staff have to track down the mismatch and re-enter the right numbers, adding duplicate work on top of the sale or shipment itself.
A cannabis POS platform with METRC integration can sync these records directly with METRC instead of requiring a separate manual entry. Staff still need to check the synced records regularly, since compliance stays the operator's responsibility, not the software's. See the automated cannabis tracking software for dispensaries and delivery operators page for more detail.
Frequently Asked Questions About METRC
What is a Metrc tag?
A Metrc tag is a serialized tag that Metrc applies to a cannabis plant or package. The tag uses RFID (radio frequency identification) technology. That technology lets the system follow the plant or package from cultivation through to the final point of sale.
Keep METRC Compliance Synced With WebJoint's Dispensary POS
WebJoint's cannabis POS software handles METRC package intake and purchase limit enforcement inside the same checkout staff already use. That can cut down on manual reconciliation, though compliance still depends on staff checking the records. Book a Demo to see how it fits your store.
