Your online store will offer customers different shipping options. They will usually have a name like Express Shipping or Standard Shipping.
If an order appears in the Carrier Not Assigned tab, ReadyToShip cannot determine which carrier service to use.
This happens when the store shipping method has not been mapped to a carrier service.
Quick Fix
Go to Settings โ Carrier Mapping
View Unmapped tab
Find the relevant store shipping method
Select the carrier
Select the carrier service
Click Apply Mapping
New orders using that shipping method will now automatically receive a carrier.
Assign a Carrier to Existing Orders
If orders have imported for the first time, or if you have a shipping method not seen by ReadyToShip before, you must assign the carrier manually.
From the Carrier Not Assigned Tab
Open Carrier Not Assigned
Select the order(s)
Click Change Carrier
Choose the carrier service
From the Order Page
Open the order
Click the shipping box icon
Select the carrier and service
The order will then move to the Unshipped tab.
What is Carrier Mapping?
Carrier Mapping links the shipping methods used in your store checkout to the carrier services used to ship orders.
Example:
Store Shipping Method | Carrier and Service |
Standard Shipping | MyPost Parcel Post + Signature |
Express Shipping | MyPost Express Post + Signature |
Once configured, ReadyToShip automatically assigns carriers to incoming orders.
Hereโs a quick video explanation:
Prevent Future Issues
Create mappings when new shipping methods are imported
Update mappings when you change your preferred carrier/service for an existing shipping method
Go to Settings โ Carrier Mapping to manage your mappings.
Once carrier mappings are set up, orders will automatically receive a carrier when they are imported.
