"Total Hours" is how long you have spent on the job, "Total"
is the total cost.
The Copy button function is only for "One Line
Item" Invoices. So if you want to charge your customer say
$35 an hour and you have several things that you charge like "Service
Charge" That would be a set price.
So this is what it is doing:
Lets add up all your columns and divide that by the
base price $35 This will give you a single value so you can copy and
paste that number to another Invoice and that would be the invoice
you would give your customer. Note: if your Timed Services are
higher than your Base Price then the copy button will not appear.
The reason for this is you can't charge more on one timed service
and claim it as your base price, either make your timed services the
same as the base price or lower.
This invoice is not included with Job
