Check Fulfillment Schedule & Availability and verify if the customer’s order is in stock or in backlog, and communicate with the customer accordingly.
If product is in-stock, check SKULabs first for shipping status.
If the order shows ‘Opened’ or ‘Delayed’ on SKULabs, verify the address with the customer if necessary and update accordingly.
If the order shows ‘ Not started’ and is indeed canceled due to fraudulent risk (see Order Canceled due to Fraudulent Risk), ask the customer to reorder and possibly try another payment method.
