# Sell EUM on your Shopify (Collective)

> Connect your Shopify store to EUM Collective: install the official app, activate your B2B account, sync the catalog, and display product data (cannabinoids, COA, shipping, pickup) with the EUM · Product Data app block.

> **EUM Collective** lets you sell the EXTRACTOS EUM® catalog in **your own Shopify store**: you install the
> official app, sync products with their [Smart COA](smart-coa.md), and an **app block** displays the product
> data (cannabinoids, shipping, COA, pickup) on your product page — automatically.
>
> **Type:** Guide (how-to). **Audience:** retailers with a Shopify store. **Status:** verified against the
> production system (2026-08-01).

## Is this for you?

* **Yes** if you have a **Shopify store** and want to sell EXTRACTOS EUM® products (dropship/resale) with
  their real data and COA.
* If instead you want to **send analysis orders** to EUM from your system (lab/store/WordPress) via code,
  that's the [API & Automation](api.md) — a different path.
* If you're a **seller who lists your own products** on EUM, go to [Sell on EUM](vender-en-eum.md).

## Step 1 — Install the official "EUM Collective" app

Installation starts from the **EUM Portal → Integrations → Shopify App** (Shopify OAuth). The flow:

1. You authorize the **EUM Collective** app in your store (products, inventory, and orders permissions).
2. **Ownership verification:** for security, we confirm the store is yours (a code sent to the *shop owner*'s
   email in Shopify). This prevents someone from connecting a store that isn't theirs.
3. When finished, your store is **linked** to your EUM Collective account.

## Step 2 — Activate your B2B account

To operate, you need a verified B2B account (3-step wizard):

1. **Operating model:** **Wholesale** — you buy in volume with tiered wholesale prices. *(Pure dropshipping
   is operated by EUM Collective and does not require a customer account.)*
2. **Identity (KYC):** you upload your **INE** (front/back) + **liveness check** (selfie). The camera opens in
   the secure verification flow.
3. **Constancia de Situación Fiscal (CSF)** (Tax Status Certificate): you upload your **CSF as a PDF** (you
   download it from the SAT); we validate the **RFC** and name against your INE. A legal entity (Persona Moral)
   also uploads the Articles of Incorporation (Acta Constitutiva).

Once confirmed, your tier is active and you enter the portal.

## Step 3 — Sync the catalog

From the **Collective portal**, you sync EUM's products to your store:

* **Product sync:** brings in the catalog (with images, variants, and **metafields** — cannabinoids, COA,
  ETA, category, pickup). You can track progress via the sync job's status.
* **Theme sync:** prepares your store to display the product data (see step 4).
* **Automatic webhooks:** **inventory** and **orders** webhooks are registered to keep stock and orders in
  sync without you having to check manually.

> **Stock and prices** live in EUM and are reflected in your store via sync + webhooks — so you don't sell
> something that's out of stock or with an outdated price.

## Step 4 — Display the product data (app block)

The **"EUM · Product Data"** app block (the *EUM · Product Data* theme extension) renders on your product page
—automatically from the metafields— the **cannabinoid profile**, the **shipping/ETA**, the **category**, the
link to the **COA** ([Smart COA](smart-coa.md)), and the **in-store pickup** info.

How to add it (Shopify OS 2.0):

1. In your Shopify admin: **Online Store → Themes → Customize**.
2. Open a **Product** template.
3. **Add section/block → Apps → "EUM · Product Data"**.
4. Place it wherever you want within the product page and **Save**.

There are no fields to configure: the block reads the metafields left by the sync. If a product shows no data,
it usually means the **sync** (step 3) needs to be run, or that product doesn't have a COA/metafields yet.

## Step 5 — Exact shipping at your checkout (optional, recommended)

We fulfill and ship your orders from our warehouse. There are two ways your customers see shipping:

* **Real-time rate (recommended):** your checkout shows the **real rate of our carrier by postal code and
  weight**, calculated by us. It requires your store to have *carrier-calculated shipping* enabled — which is
  **free** if you switch your Shopify to **annual billing** (Settings → Plan), and it saves you on your
  subscription too. Once active, we connect shipping automatically; nothing to configure.
* **Simple rate (default):** if you don't enable the above, your store uses a **flat rate** we leave configured
  for our products. You can adjust it in your Shopify shipping zones.

Either way, at settlement we charge you the **real** shipping cost — so make sure what you charge your customer
covers it. Your `/collective` portal shows a prompt guiding you to enable real-time shipping when it applies.

## Step 6 — Put YOUR own COA on YOUR product (the differentiator)

If you generate a **COA** with us for a product of **yours** (not from the Collective catalog), you can give it
the **same premium product card** you see in our store: cannabinoids, **potency profile**, composition, and a
**verified COA** badge — all computed automatically.

How:

1. In your `/collective` portal → **My COAs** tab.
2. **Link** your COA to your **SKU**.
3. Done: the card appears on that product. Whenever you **update** that COA, your product updates itself.

You'll get an email when you generate a COA, with a **preview of how your card will look**.

> **Important — shipping and pickup for YOUR own products:** products you link via COA→SKU are **yours** (we
> don't fulfill them), so they use **your own shipping** and do **NOT** show "pick up at our CDMX branch".
> Pickup at our warehouse (C. Guillermo Prieto 64, CDMX) applies **only to EUM Collective products** that we
> sync and fulfill. It's automatic: your own products' card shows the COA's cannabinoids, potency and badges,
> but no EUM pickup or shipping.

## Step 7 — Collecting on orders (wallet)

The portal includes a **wallet** and payment methods to settle your wholesale orders (top up balance and pay
for an order). Orders from your store come in via webhook and are reconciled against your account.

## How it connects with the rest of the system

* The **product data** shown by the app block comes from the same **[Smart COA](smart-coa.md)** (real
  per-batch analysis, QR/CVV, public verification).
* The **labeling** and the rules by product class are in [Compliance & Labeling](cumplimiento/README.md).
* For integration via **code** (sending analysis orders, receiving HMAC-signed webhooks), go to
  [API & Automation](api.md).

*Verified against the production system on 2026-08-01. The official app is **EUM Collective**; the theme
extension is **EUM · Product Data**.*
