With ShipperHQ rating you may wish to use different carriers based on origins or your rules around shipping groups.
For example you may want to ship from NY using FedEx and ship from CA using UPS.
ShipperHQ needs to be able to map rates from these different origins when items from NY and CA are in the cart, otherwise it has no idea to push the rates together and no rates will show. The Carrier Merge section allows you to set this up.
Set-up—Multi-Origin & Drop Shipping
To turn on Drop Shipping you will need to go to the Account Settings in the top right corner
Account Settings–>Features–> Multi-Origin & Drop Shipping –> Update
Shipping with the Same Carrier
If all your products are shipped via the same carrier then there is no need to set up merged rates, they will be shown using the carrier name.
Shipping with Separate Carriers
Let’s take the above example with FedEx and UPS. If you are using different origins that could result in a scenario where FedEx Rates are returned for one origin and UPS rates are returned for another origin you need to set up merge rules.
If you look at the example in this screenshot here we are saying that if FedEx and UPS are in the cart show “2nd Day” when adding FedEx ‘2nd Day’ and UPS ‘UPS 2nd Day Air’ together.
Showing Split Rates
On some platforms (Magento 1/Zoey) it is possible to show a breakdown of the rates per origin in the checkout. This is specified in the Settings under Origins. Even if you set to show this breakdown ShipperHQ will still show merged rates in the cart as we believe it is better to keep the shipping quote estimation simple.
If you see the error message ‘No merged rates then please review your carrier merge rules‘ then you need to review your settings for merging rates. This error implies that it can find rates for the products when individually in the cart e.g. for Origin A can find FedEx rates, for Origin B can find UPS rates, but there are not sufficient rules to merge those rates together (e.g. Ground maps FedEx Ground and UPS Ground).
If you think you have a problem with merging of rates then the best way to determine is if you can see that when you add 1 product from Origin A it shows rates, when you clear the cart and add a product from Origin B it shows rates, but not when in the cart together – thats more than likely a rate merge issue.
