It would be nice if the system could combine like product items and services:
IE, Two technicians put logs on one ticket for remote support; rather than having 2 items on the invoice showing remote support, 1 hour each. The invoice would show 1 line item for Remote Support, total of 2 hours.
There are also occasions where we don’t want to group the line items though (e.g. where the description indicates the call out date).
For flexibility, I see this being a button on the invoice that says “Group by product”. This can then look at items already added and group all line items of the same product together with total quantity / $. The description could be automatically set to whatever the description was on the first line item of that product.
