01 The ~20% tax, layered
Rhode Island stacks a 10% state cannabis excise, a 3% local cannabis excise, and the 7% state sales tax, landing around 20% at the register. SellStack's tax engine applies all three from one configuration.
HB 8544 voided the prior retail-license round and ordered the Cannabis Control Commission to stand up a new process, which opened its Adult-Use Retail Licensing Portal on August 7, 2026. Just 24 new licenses are on the table, four per zone across six zones, split between general, social-equity, and worker-owned-cooperative set-asides. Stacked on top is a roughly 20% tax at the register and mandatory Metrc. In a market this tightly bounded, the operators who move cleanly through the new process and run airtight track-and-trace are the ones who compete.
SellStack handles the seven Rhode Island realities as one ledger. The process can keep moving. Your operations do not have to.
Rhode Island is a small, tightly limited-license market where adult-use rules took effect in 2025 and a 2026 law reset the retail-license process from scratch. Scarcity, set-asides, and clean track-and-trace decide who competes. Four realities carry the most operational weight.
One ledger, not five tools stitched together. Each links to the detail on the next page.

Rhode Island runs on Metrc under the Cannabis Control Commission, mandatory for all licensees. SellStack Cannabis ERP-Commerce ships with native Metrc integration, reconciled from your own ledger.
Rhode Island caps the market at 24 new adult-use retail licenses across six zones, four per zone, alongside nine compassion centers. SellStack runs the multi-entity, multi-zone operation from one ledger.
Compassion centers in good standing can sell adult-use through a hybrid pathway, and the new licenses reserve social-equity and worker-cooperative seats. SellStack runs medical, adult-use, and hybrid from one lot-aware ledger.
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 Rhode Island 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 Rhode Island 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 Commission 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 on Metrc, B2C retail, licensed delivery, and medical compassion-center sales, on one ledger with lot-level traceability and ERP integration, across every zone and entity you hold.
