I work as a bike messenger and we have to fill a double invoice (with a carbon copy) for every single trip. The format of the invoice is a useful A6 148 mm x 104 mm (about 5.8" x 4"😉.
At the end of the day we have a hard time collecting and ordering the invoices to make it ready for the accounting.
What kind of system do you use for tracking the trips? Do you use another format, a booklet or something really different?
