01 Potency-tiered tax, layered
Illinois taxes adult-use by potency, 10%, 20%, or 25%, then stacks 6.25% state sales tax and local add-ons. SellStack's tax engine applies the right tier per item from one configuration.
Illinois taxes adult-use product by potency, 10%, 20%, or 25% excise depending on the item, plus 6.25% state sales tax and local add-ons that push Chicago past 40% combined. The state runs on Metrc now, with IDFPR over dispensaries and the Department of Agriculture over everything upstream. Home delivery is still banned, and the new pickup and drive-through lane only works if your order flow and floor plan hold up. Prices are falling even as unit volume hits records, so reconciliation friction comes straight out of margin.
SellStack handles the seven Illinois realities as one ledger. The rules can keep moving. Your operations do not have to.
Illinois runs a mature, license-constrained market where dollar sales fell in FY2026 even as unit volume set records. Falling prices, a potency-tiered tax, two regulators sharing Metrc, and a delivery ban that just gained a pickup lane are all landing at once. Four of them carry the most operational weight.
One ledger, not five tools stitched together. Each links to the detail on the next page.

Illinois moved to Metrc in 2025, with IDFPR over dispensaries and the Department of Agriculture over everything upstream. SellStack Cannabis ERP-Commerce ships with native Metrc integration, reconciled from your own ledger.
Illinois bans home delivery; the 2026 law PA 104-0463 added online order plus pickup and drive-through at the licensed premises. SellStack owns the order and carries it into fulfillment, with B2B transporter handoffs on the same ledger.
Social equity is the defining feature of Illinois licensing, with later rounds awarded by lottery and eligibility still in litigation. SellStack keeps the operating records a multi-entity, equity-licensed operator needs under one 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 Illinois 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 Illinois 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 IDFPR and the Department of Agriculture see already matches the record you run your business on. When Illinois 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 moved by licensed transporters, in-store retail, compliant pickup and drive-through, and medical program fulfillment, on one ledger with lot-level traceability, potency-tiered tax, and ERP integration.
