Expansion stores and multi-store setups with Shopify Plus

What expansion stores are

Expansion stores are additional stores within your Shopify Plus organization. According to Shopify's documentation, Plus includes up to ten stores at no extra cost: the main one and nine expansion stores. Staging stores don't count toward that limit, and if you need more than ten you have to talk to Shopify Support.

If a new store exceeds your contract limits, it starts as a test store and you have to approve an additional cost to activate it. The exact terms depend on each Plus contract, so review them with Shopify before planning.

What's shared and what isn't

From the organization you manage users and billing centrally. That lets you give one person access to several stores with different permissions in each, without creating duplicate accounts.

Almost everything else is not shared by default. Settings, products, collections and inventory don't sync between stores, and a change in one doesn't appear in the others. You can only import data from another store when creating the new one. To keep catalogs or stock aligned, you need sync apps or a connected ERP.

• Shared: users and billing from the organization
• Independent: products, collections and inventory
• Independent: each store's settings, payments and shipping
• Per store: apps (billed in each one)
• Per store: theme license, which can't be shared

When an expansion store makes sense

The clearest cases are separate brands with their own identity, catalog and team, where mixing everything into one store only complicates management. It also makes sense to separate a wholesale channel when its operations, payment terms or team are very different from the consumer channel, although Plus supports native B2B on Shopify in the same store.

One case often gets confused: opening another store just to have a different design for a campaign or product line. That's better solved with Online Store 2.0 theme templates and sections within the same store, without duplicating the catalog or apps. An expansion store makes sense when the business changes; a new look alone doesn't justify one.

Another case is countries with very different requirements: catalogs that don't resemble each other, separate logistics or different legal entities that invoice on their own. There, one store per country can simplify accounting and operations.

When Shopify Markets is enough

Before opening a store per country, see whether Shopify Markets solves it. Markets, available on all plans, lets you sell in several countries from a single store with local prices and currency, languages, domains or subfolders per market and custom domains, and Shopify adds hreflang tags automatically.

A single store with Markets means one catalog, one inventory, one theme and one set of apps. For most brands that sell the same products in several countries, it's the simplest and cheapest option to maintain. Separate stores pay off when the differences between markets are about the business, not just language and currency.

The hidden cost of multiple stores

Every new store multiplies the work. Apps are paid per store, the theme needs its own license in each one, and any improvement to the design or a section has to be deployed several times. If the theme code is shared, manage it with version control so you can publish changes to all stores at once.

The catalog is the other front. Without a single source of data, like an ERP or a PIM, keeping prices, descriptions and stock consistent across stores ends up being a manual, error-prone task. That sync system should be designed before opening the second store.

How to plan a multi-store architecture

Start by defining what's common and what's different in each store: catalog, prices, language, logistics, team and legal entity. With that you decide whether one store with Markets, one store with native B2B or several stores in the organization is the better fit.

If you go with several stores, define from the start the catalog's data source, how inventory syncs, how the theme gets deployed and which permissions each person has in each store. Shopify Flow, free on all the main plans, helps with automations inside each store, but it doesn't replace a sync system between them.
