The full journey to sell: register, create your products, certify them with Smart COA, label them in compliance, ship them to the warehouse, and get paid. Each step is gated by the system so that a product is not sold until it is complete and verified. Type: How-to. Audience: sellers. Status: v1 (2026-08-01, verified against the system).

​
3.1 Registration and onboarding

Becoming a seller reuses your same verified identity (you don’t create another account). Steps:
  1. Verify your identity (KYC) — required to operate.
  2. Register as a seller — you are assigned your SKU prefix.
  3. Tax details (CSF) — you upload your Constancia de Situación Fiscal (Tax Status Certificate); from it comes your RFC and tax regime (which defines your withholdings).
  4. CLABE — an account in the name of the holder of your CSF; that’s where you receive your SPEI deposits.
  5. Accept the Terms and Conditions.
Once you meet the requirements, your account becomes active and your /vender panel opens. (Seller registration includes your tax profile and B2B account in the same flow — no CSF, no registration.)

​
3.2 Create a product (simple vs variable)

  • Simple product — a single SKU. The SKU is generated upon approval.
  • Variable product — several presentations (weight, flavor, volume…). Each variant has its own SKU (that’s how Shopify handles it natively). You define options + values and the combinations are generated.
  • Photos per variant — you can upload your own image per variant; in the store, choosing the variant changes the photo.
  • Raw material vs finished product — you choose this first; it defines whether “total potency” applies (one COA for all variants, typical of raw material) or COA per variant (finished product = each presentation is a different batch).

​
3.3 Product classes

How your product is classified determines its labeling and paperwork (details in the Compliance section): confectionery · dietary supplement · food/edible fats · cosmetic · cartridge/container · raw material (cannabinoid input: isolated/broad/full-spectrum CBD, HHC, HHC-O, CBN, CBG). Choose carefully: this determines which NOM and which seals/legends apply, and whether it’s a consumer label or an input identification label.

​
3.4 Your product’s Smart COA

Three ways to give it its Smart COA:
  1. Upload the PDF of a COA from your laboratory → it enters review; the EUM team extracts and releases it.
  2. Use an existing COA that you already have in your name (you paste its folio/token).
  3. Send for analysis — you send a sample to a laboratory; when the COA is released it is attached only to your product.
Validity (hard rule): a COA is valid for 1.8 years from the analysis date (not from when you upload it). A COA that is expired or has no analysis date cannot be released or published. Without a released and valid COA, your product stays in draft.

​
3.5 Compliant labeling

Every piece you send to the warehouse must carry its label with a barcode (SKU) + QR (to the Smart COA) + CVV (anti-counterfeit) — they are generated from Label Studio on your product. Without an approved COA, label printing is not activated. The regulatory requirements for the label by product class (NOM fields, seals, legends) are covered in the Compliance section (under construction, being verified with an official source).

​
3.6 Prices

You set the retail price, and optionally wholesale (B2B) with minimums and volume tiers per variant. The breakdown of what you receive (price − commission − withholdings = net) is calculated with the current %.

​
3.7 Inventory and transfers to warehouse

  • You see the live stock of your products, with a breakdown by warehouse when there is more than one.
  • You send inventory by creating a transfer to the enabled warehouse. Only published products (with a released COA + published in the store) can be transferred: a draft or a product without a COA cannot be sent to the warehouse (its path is to send it for analysis first).
  • You only see your transfers, never those of others.

​
3.8 Shipping labels (mandatory)

We don’t receive packages without a registered shipping label — neither at the warehouse nor at the laboratory. Two options:
  1. Your own label — you register the carrier + tracking number. We verify it with the carrier and track it.
  2. Buy the label in the system — you get quotes across carriers, choose, and pay for it with your credit (you top up by buying a pack; the charge is within the platform). The label is issued and ready.
If you don’t register a label, we remind you every 24 h. Once it’s on its way, you’ll see the real tracking status (in transit → delivered) and we notify you when your stock arrives.

​
3.9 Your product’s states (and what to do in each)

On variable products, each variant shows its own state (same vocabulary), so you know which one is missing.

​
3.10 Payments, commissions, withholdings, and certificates

  • At the end of the month you receive your account statement: gross sales − EUM commission − withholdings (ISR + IVA according to your tax regime) = net, deposited by SPEI (with its receipt).
  • You receive your withholding certificates and, when applicable, the commission invoices that EUM issues to you.

​
3.11 Seizure = neutral (you are neither charged nor paid)

If a shipment to the customer is seized, that product is lost for the seller and for EUM: it generates no commission or payment. The system automatically deducts those sales from your settlement (we don’t pay you for product that didn’t arrive, nor do we charge you commission for it). In the Zones section you see the risk by postal code and the impact on your own products.
