The best way to get how much each order was and how much you charged for delivery is to use the 'Bulk Download/ Print' option on your project list.
​
You can first set the date range on your Project List (Click Specific Dates if you want to do a range)
Then, Select just your signed contracts (so you know they are confirmed)

Next, select all the orders that show in this list
Finally, click the Bulk Download option and send yourself all of the contracts for these projects.

You can choose to either receive the individual files, or select to combine all the files into a single document for easy printing.
