Items with a duration – price per day, week or month
Three stage modules, seven days, €12.00 per module and day: the Duration plugin calculates 3 × 7 × 12.00 = €252.00 in a single item. Quantity and unit price stay as they are; the duration is added as a third factor.
1. Get the plugin
Download the Duration plugin, unzip it and double-click to install. It requires GrandTotal 10.
2. Add an item
The items list's Insert menu has a Duration entry. The item has two extra fields: the duration, preset to 1, and the unit, for example “days”. Amount = quantity × unit price × duration, rounded to the cent. Discount and tax work as with any other item. In the catalog, an item can be created with the type Duration.
