# Linked stores

> Link the Shopify stores that share one supply chain, map the products and warehouses they have in common, and buy for all of them from one combined reorder list.

Many brands run more than one Shopify store for the same stock: a retail store and a wholesale store, or one store per country. Each installs Stockful on its own and keeps its own subscription, settings and forecasts. Linking them lets Stockful pool their demand and stock, so you see one number to buy for the whole business instead of reconciling two reorder lists by hand.

Linked stores live in **Settings → Linked stores**.

## Linking a store

1. In the first store, open **Settings → Linked stores** and click **Link a store**.
2. Enter the other store's `myshopify.com` domain and send the request.
3. Someone with access to the other store's Stockful opens its **Linked stores** page and clicks **Accept**. A banner in that store points them there while a request is waiting.

Nothing is shared until the other store accepts. Once it does, both stores see the link, and clicking it opens the link's page: who requested it, who accepted it, and the mappings below.

<Note>
  Either store can unlink at any time from the link's page, and uninstalling Stockful from one store ends every link it was on. The other store is emailed either way. Combined numbers stop straight away.
</Note>

## Mapping products

A link on its own does nothing. Stockful needs to know which product in one store is the same stock as a product in the other, and in what units.

On the link's page, under **Products**:

* **Suggest matches** pairs products that share a SKU or barcode across the two stores. Untick any that are not the same stock and map the rest in one go.
* **Add mapping** pairs two products by hand: enter a SKU or barcode on each side and find the match.

Every pairing carries **units**: how many of this store's units equal how many of the other store's. Two stores selling the same single item are 1 here = 1 there. A wholesale store that sells a box of ten of the retail store's single is **10 here = 1 there** from the retail store's side. Change the units on any row with the edit icon.

Mappings are saved from the save bar, like other Stockful pages, and take effect on the combined view within a few minutes.

## Warehouses

If both stores hold stock at the **same physical place**, pair the two location records under **Warehouses** so that stock is counted once rather than twice. Leave genuinely separate warehouses unmapped.

## The combined view

With at least one product mapped, the [reorder recommendations](/user-guide/purchasing/reorder-recommendations) location selector gains a **Combined with** option, named for the linked store. It shows **one row per mapped product**, with everything converted to this store's units:

| Column       | What it shows                                                                                                     |
| ------------ | ----------------------------------------------------------------------------------------------------------------- |
| **On hand**  | This store's stock plus the linked store's stock of the mapped product, with the split beneath                    |
| **Incoming** | Stock on its way to either store, including units on open purchase orders in either store, with the split beneath |
| **To order** | The pooled quantity to buy, from the combined demand of both stores, netted against all of that secured supply    |

Your store's own settings govern the calculation: lead time, safety stock, restock-to days, min/max policies and any velocity override apply to the pooled numbers exactly as they do elsewhere. The linked store contributes its demand, stock and open orders only.

A product appears in the combined view when the **pool** is below target. Something low here but well covered there will not show, because there is nothing to buy.

Adding rows to a purchase order from the combined view raises the order **in this store** for the pooled quantity. Split it across the stores when you receive it, or raise an order from the other store for its share.

## What stays separate

* Each store keeps its own **subscription and billing**. There is no pooled SKU allowance.
* Each store keeps its own **forecast settings, alerts and reports**. Only the combined view reads across the link.
* The linked store never sees your customers, orders or costs. Stockful reads its mapped products' demand and stock, converted to your units, and nothing else.

<Tip>
  Map the products first with **Suggest matches**, then fix the units on the few rows where one store sells packs. The combined view is only as good as the mappings under it.
