Why this is not a thing, I just don't understand.   

Holy crap.. You can't search?  How stupid is this/  Shame on you shopify. Pure lazyness.  Bad project 

We have a motorcycle repair shop. I'd like to be on my laptop in the back and create a quick invoice that my technicians can edit later and add parts and labor. Right now I have a $0 item came draft hack and place that in the order, then mark as paid...
