Hi Thomas,
The best way to set this up would be to use the Manual Min Amount section in the plugin’s settings. I am assuming by 2 companies you mean 2 different shipping methods. Here are the options to configure in the plugin’s settings:
– Manual Min Amount > Section > Enable
– Manual Min Amount > Extra options > Shipping methods > Select the 2 shipping methods and save the settings.
– Manual Min Amount > Extra options: Amounts > Here you will now find a field for both your shipping methods. You can set the minimum amount as 50 and 70 for each.
