Modalyst keeps inventory synced with Shopify, even if the order does not originate from a Modalyst Retailer. Please ensure that Shopify tracks each product’s inventory. This must be selected under the Inventory Policy of each item.
Modalyst will sync any orders which take place with your own ecommerce site and/or any other sales channel. This means that Modalyst will sync the inventory count to match the number in your Shopify account.
