Shopify Plus has a feature called the "Shopify Organization Admin", which allows users with multiple stores to manage their different locations all in one place. You can read more about this Shopify feature here, and in this article we'll discuss how it may affect your integration.
While Modern Retail's integration works when you have multiple physical locations under the banner of one store (this does require our "pro" integration), if you have different stores, with different catalogues, you'll need to purchase an additional integration. So, in the case of Shopify's Organization Admin (which is helpful for managing different stores under a larger organization!) you would need another integration for any additional stores.
Typically the process of setting up additional integrations is even faster than our initial setup. If you have multiple integrations, you can manage each of them using the same account in the Modern Retail Admin Panel.
If you're interested in setting up a new integration with us, or if you have any additional questions, please feel free to contact us on our website, or with a support request if you're an existing client.
