Adult-use product carries a 10.75% cannabis excise, the 6.25% state sales tax, and a local excise of up to 3%, while registered medical patients are exempt from all three. Delivery stays reserved for equity-tier licensees, a window the CCC voted on January 15, 2026 to extend to at least April 2029. Metrc runs statewide under the Cannabis Control Commission. In a price-compressed market, operators reconciling tax layers, channels, and Metrc by hand are giving back margin they cannot spare.
SellStack handles the seven Massachusetts realities as one ledger. The rules can keep moving. Your operations do not have to.
Massachusetts is a mature, price-compressed market with layered taxation, equity-reserved delivery, and active oversight. 2026 sales topped roughly $800 million through mid-year amid wholesale price erosion. Four realities carry the most operational weight.
One ledger, not five tools stitched together. Each links to the detail on the next page.
Adult-use carries the 10.75% cannabis excise, the 6.25% sales tax, and a local excise up to 3%, while registered medical patients are exempt from all three. SellStack's tax engine applies the right treatment per channel from one configuration.
Massachusetts runs on Metrc statewide under the CCC, with serialized tags from cultivation to retail. SellStack Cannabis ERP-Commerce ships with native Metrc integration, reconciled from your own ledger.
Massachusetts delivery is reserved for equity-tier licensees: Delivery Couriers who cannot hold title or warehouse, and Delivery Operators who can. The CCC voted on January 15, 2026 to extend that exclusivity to at least April 2029. SellStack owns the order and carries it into the right delivery model.
Massachusetts regulates Medical Marijuana Treatment Centers and adult-use Marijuana Establishments under the CCC, with different tax treatment. SellStack runs both channels from one lot-aware ledger, so medical and retail never drift apart.
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 Massachusetts medical operators. The records half is built in, as a byproduct of operating normally.
SellStack moves the numbers on both sides of the ledger. Streamlined automation lifts productivity, so more of every sale reaches the bottom line instead of being spent on manual compliance and reconciliation work. And SellStack's B2B buyer tools have increased buyer purchasing by 50 to 75% in measured results (SellStack Insights Reporting), turning the wholesale relationships you already have into more volume without more headcount.
SellStack ships the commerce and records layer for Massachusetts 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 CCC changes a rule, 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 between establishments, B2C retail and in-store pickup, equity-tier delivery as a Courier or Operator, and tax-exempt medical through a Treatment Center, on one ledger with lot-level traceability and ERP integration.
