Free Interpreter Invoice Template & Generator

Your invoice needs to show the date and time of each interpretation assignment, the language pair you worked with, and whether it was consecutive or simultaneous interpretation. Include your hourly or half-day rate, any minimum charges that applied, and travel time if you bill for it. Clients need this breakdown for their records, and accounting departments will kick back vague invoices that just say "interpretation services."

Most interpreters bill after the work is done with net 30 terms, though some ask for 50% upfront for new clients or large multi-day conferences. Rush jobs under 48 hours notice should carry a premium rate that you state clearly on the invoice. For contract work through agencies, expect net 45 or even net 60, which is frustrating but standard.

Send your invoice the same day the job finishes, not a week later. Late invoices go to the bottom of the payment queue. Also, track your cancellation policy strictly. If a client cancels within your notice period (usually 24-48 hours), bill the full amount or your stated cancellation fee. People will test this boundary, and if you don't enforce it once, they'll remember.
