Tax Settings

• Rename the current "Inclusive" tax type to "Inclusive (Additive)"
• Add a new tax type at the top of the list called "Inclusive"
• Update the text of the Tax Type tooltip with the following:

  Inclusive will calculate tax as a part of the item prices you set.
  Inclusive (Additive) will calculate tax in addition to the item prices you set.
  Exclusive will calculate tax in addition to the item prices you set, but will not include it in the order total display.

Behavior

When the new "Inclusive" tax type is selected, tax should be calculated as a part of set prices. For example, if an services costs $100 and there is a tax of 10% then the service line item would be $90.91 and the tax line item would be $9.09 so the overall total would come out to $100.

• To calculate the service price, use the equation
  • $price = $package_price / (100 + $tax_percentage)
• To calculate the tax amount use the equation
  • $tax_price = ( $package_price / ( 100 + $tax_percentage ) ) x $tax_percentage

This should be handled by the pricing presenter.

• All pricing drop downs for packages or configurable options. For example:

  • The Billing > Services widget
  • The client profile Services widget
