Picture a wholesale operator running a Friday flower promo on a single SKU.

Inventory shows 80 units. Behind those 80 units sit four lots — different cultivars, different cost basis, different THC results, different harvest dates. The promo discount applies to every unit equally. The menu shows availability as if the lots were interchangeable. The order picks whichever case is closest. The COA delivered to the customer may or may not match what's in the box. By Monday, finance is reconciling margin against the wrong cost. By Wednesday, compliance is reconciling product attribution against the wrong lot. Everyone is doing more work to undo decisions that were made without lot-level visibility in the first place.

We rebuilt the unit of cannabis commerce.

SellStack treats lots as primary, not as a metadata footnote on a SKU. Inventory keys to lots. Pricing keys to lots. Discounts key to lots. Menus reflect lot-finite availability. Orders lock to specific lots at placement. COAs travel with the lot, not the SKU. Behind the scenes, FIFO allocation, UoM conversion, and case-breaking happen automatically — so the seller's commerce stack stops fighting the realities that compliance, finance, and the customer already know to be true. Compliance becomes the foundation. Sales control sits on top. Velocity is the result everyone has been chasing.
