01 Two cannabis taxes, one moving base
SellStack's native tax engine handles the 15% excise on the quarterly Average Market Rate and the 15% special retail sales tax, plus local taxes, calculated at configuration.
Colorado has sold adult-use cannabis since 2014 and invented Metrc. Now it is a consolidation market: wholesale prices are down sharply from their 2021 peak, the Average Market Rate that sets the excise resets every quarter, concentrate testing just expanded, and Metrc is locked in through 2029 with new consumer QR codes. Margins are too thin to lose to reconciliation work.
SellStack handles seven Colorado realities as one ledger. In a market this tight, the efficiency is the edge.
Colorado is a mature market, not a new rollout. The pressures are consolidation, price compression, a quarterly-shifting excise base, and steady regulatory refinement. Four pieces carry the most operational weight.
One ledger, not separate tools stitched together. Each links to the detail on the next page.

Colorado has no mandatory distributor tier. SellStack runs direct cultivator-to-manufacturer-to-store transfers, and optional transporter movement, from one ledger.
Colorado invented Metrc and has extended it through 2029, adding consumer QR codes and regulator analytics. SellStack reconciles Metrc from the ledger, so a Metrc change does not rebuild your inventory logic.
Colorado permits consumer delivery under a Courier License where the local jurisdiction opts in. SellStack owns the order and integrates with your delivery platform, with the opt-in limits enforced.
Every inventory, sales, and test record carries the lot identifier from receipt through sale, so the lot genealogy is the ledger. Metrc reconciliation and GMP both fall out of it.
SellStack Cannabis ERP-Commerce backs onto your ERP or warehouse platform. Microsoft Dynamics 365 Cannabis on Business Central is fully supported, so financials, inventory, and commerce run from one ledger.
The federal GMP clock started April 28, 2026 for Colorado medical operators. The records half is built in, as a byproduct of operating normally.
SellStack ships the commerce and records layer for Colorado cannabis operators. It does not stand in for the parts of compliance that are yours:
SellStack does not replace Metrc either. It reconciles to it, so the lot-level record the state sees already matches the record you run your business on. When the MED adds to Metrc or refines its rules, SellStack's configuration layer handles the adaptation and your inventory logic stays stable.
SellStack is the cannabis commerce engine for operators running real multi-channel, multi-entity operations: B2B wholesale and direct transfers, B2C retail, courier delivery, and medical patient service, on one ledger with lot-level traceability and ERP integration.
