Please note that if you are using Modalyst you must not set your Shopify account to fulfill orders automatically.
If this setting is enabled on Shopify, then any order you receive on Shopify will automatically be updated on Modalyst to "fulfilled" before you even get a chance to pay the supplier for the order.
Why is this problematic? If your orders are automatically updating to fulfill before you pay the supplier on Modalyst, Shein, or Wish, then your orders will be incorrectly recognized as Shipped and Completed on Modalyst, thereby preventing you from taking the steps necessary to ensure that the orders are paid for and ultimately shipped to your customer.
If you have any further questions about how orders are fulfilled on Modalyst, Shein, or Wish, please let us know at firstname.lastname@example.org.
