Discounts (rate modifiers)

[chargio]

User Story

As a user, i want to be able to use discounts in my rates. (rates modifiers)

• Percentage discounts: Reduce 5% of the bill for each item applied
• Fixed discount: 1 $ discount per item.
  Discounts should be positive or negative. Standard discounts should be negative (a reduction on price).
  Discounts should be possible to be set up at item level or at group level, and to be applied at rating time (when the item is being rated), or at bill time (when the bill is being closed).

Role

Assumptions

• The user can define whether the fixed discount can change positive numbers into negative numbers or there is a floor and a ceiling for them.
• Discounts can be applied to the same group or to another (i.e. The results of the discounts are applied to the bill or the account, not to the item).

UI Details

There must be a way of defining a discount in the price plan editor.
