Answer 1

We can set the FlatTax to be inclusive by adding the following to our shop.yml and flushing the site cache:

SilverShop\Model\Modifiers\Tax\FlatTax:
  exclusive: false

By checking the src/Model/Modifiers/Tax/FlatTax.php we can see what the config settings are for the FlatTax class.

We can also change the flat tax rate and the name of the flat tax like so:

SilverShop\Model\Modifiers\Tax\FlatTax:
  exclusive: false
  rate: 0.20
  name: 'VAT'

By checking the src/Model/Modifiers/Shipping/Simple.php we can see what the config settings are for the Simple shipping class. We can also change these default settings:

SilverShop\Model\Modifiers\Shipping:
  default_charge: 10
  charges_by_country:
    - 'AU': 20
    - 'FR': 15
