Service items and groups are used in documents inside a pricing widget.

Items are services that you sell to your customers.  They have a title, description, cost price, unit price and recurring frequency - this can none, monthly, quarterly, semi-annually or yearly.

Service items can be organised into groups.  With the group it can be given a title, description and recurring frequency (the group’s recurring frequency overrides the recurring frequency of the service items, if they have that set).  Under cost options, you can specify whether the total of the group is the total of the  service items, or a specific price.  Also, you can apply a discount as a dollar amount or a percent.
