SKULabs supports importing order ship by dates from sales channels who naturally support them, such as Amazon. However, some sales channels, such as Shopify, do not have these dates built in by default.
There are a few ways around this:
Shipping rules can tag orders based on the date an order was placed to help you determine which orders are closer to your teams standard fulfillment window.
Determine how long your team takes to ship orders after they are placed and whether that duration is consistent across all orders. Next, set up a shipping rule with "Order date" as a criteria and "Set order tag" as an action.

Use Shopify Scripts to add note attributes to orders
Ask Shopify Plus support and research how you could use Shopify Scripts to add customized note attributes to orders. Shopify Scripts are included for Shopify Plus sellers and recommended because it may allow you to avoid additional cost and using another app.
Shopify order note attributes named "Ship Date", "Delivery Date", and "Pickup Date" can be imported into SKULabs. The values should be a UTC date formatted in extended ISO8601.
"name": "Ship Date",
Tip: Values for "Delivery Date" and "Pickup Date" are used as fallbacks if a "Ship Date" value is not present.
Search the app store
If this cannot be done using Shopify Scripts, search the Shopify app store and ask in Shopify forums for a third-party app that handles Ship by or Delivery dates. When you find an app that you think will do the job, contact the app developer and ask if they append a "Ship Date" "note attribute to orders."
