Platform
The cannabis supply chain, in two products
Operators buy in Purchase Pro. Suppliers fulfill in Supplier Core. MainStem Phenom works inside both apps, with the permissions of the person signed in.
For operators
Purchase Pro™
Procurement for cannabis operators. Shop the marketplace, approve a requisition, issue the purchase order, receive it, and match the invoice. Cannabis purchasing adds regional buying, approvals, three-way matching, and AP on the same record.
Marketplace
Search products and suppliers, then build a requisition from what you find.
Organization
Locations, departments, users, and catalogs define who can buy what.
Requisitions and approvals
Demand is reviewed in a checkout before it becomes a purchase order.
RFQ and bulk ordering
Quote a spec, or place one buy across many locations.
Punch-outs
Shop a supplier such as Amazon Business and return the cart to the requisition.
Cannabis purchasing
Regional purchasing, approvals, three-way matching, and AP in one lane.
Logistics
Shipments, receiving, and returns stay on the order they belong to.
Reporting
Line items, unfulfilled requisitions, order history, accruals, and punch-outs.
MainStem Phenom™
An assistant in the app that can only do what the signed-in user can do.
For suppliers
Supplier Core™
Where a supplier manages the catalog operators buy, the orders they place, and the quotes they request. Fulfill with pick, pack, and ship. Publish a Shopify sales channel, or sync products through the API.
Product catalog
Suppliers create and maintain the products operators order.
Orders
Incoming orders, with pick, pack, and ship on the fulfillment.
Requests for quote
Answer an operator’s RFQ in the same system the order will live in.
Returns
Product coming back is a record, not an email thread.
Shopify sales channel
Publish into Shopify without keeping a second catalog by hand.
Product sync API
Push catalog updates from the supplier’s own systems.
Agents
Claude, ChatGPT, and MCP act with that supplier user’s permissions.
Keep supplier notifications on the work they are about.
MainStem Phenom™
The same assistant operators use, scoped to the supplier’s account.
