Never use certain services or package types? Some shipping services might be too slow or too expensive for your business, so why scroll past them when you can hide them account-wide?
It's easy to turn off shipping services or package types that you don't use.
Head to your Account Settings (the gear icon in the upper right).
Next, select Shipping and then Shipping Services from the sidebar on the left.
(Alternatively, click Packages in the left sidebar if you want to disable certain package types.)
For each option you want to hide, simply remove their corresponding checkmarks and Save Changes.
Going forward, any disabled packages or services won't show up as options elsewhere in the ShipStation interface. This will affect any and all users on your account.
To enable/re-enable a service, simply add the checks back to the appropriate boxes. Keep in mind that you should only enable services that your carrier's approved you for, otherwise you'll get errors while shipping.
