Why do I have two qty columns on my invoice
In most cases, you will usually only see a Qty/Units column.
This refers to the number of the currently selected selling units for that item.
So, this can be time-based units like Days, Weeks, Months ect.
If the selected unit is non time-based, then it will count as the number of items as well.
The Qty/Items column will appear if you've added in a Bulk Item (an Item with a Qty for hire of more than 1).
This column refers to the number of items, as opposed to the number of the currently selected selling unit, like Qty/Units above.
