Last year I watched a freelance designer send 47 follow-up emails over 61 days. Polite ones. Scheduled ones. One opened with "just bumping this to the top of your inbox." The client finally paid, apologized, and then mentioned their invoices had never listed a due date. "Net 30" was sitting there in the fine print, apparently decorative.
That's the part nobody says out loud. Late payment barely starts with the invoice. It starts with what you wrote, or didn't, before the work began.
The advice you'll hear in every thread is some mix of: follow up faster, stay firm but friendly, charge a late fee. It all assumes the client is forgetful and you need better reminders. In my experience, most late payers aren't forgetful. They're running on the terms you gave them, and you gave them a lot of slack.
Three things that moved our numbers more than any follow-up template:
A specific date, not net 30. "Due October 14" beats "net 30" every time because it forces both sides to do the math. Vague terms invite vague payment.
A late fee agreed to up front, not sprung later. A signed clause you rarely invoke is still worth having. It moves you from chaser to contract holder the moment a conversation gets awkward.
A kill switch. A written point where you pause further work until the balance clears. Freelancers avoid this because it feels aggressive. Ten years in, I've seen it do the opposite: clients respect the boundary, and you stop funding their cash-flow problem with your labor.
Notice none of these involve sending more emails. Follow-ups aren't the lever. Terms are. Every friendly bump you send without tightening the underlying terms just trains the client that your deadlines are suggestions with feelings attached.

the due date is the part i'd copy first. one more place for it is the invoice email itself, not only the contract, since that's the message the client's accountant actually reads. then the date and the pause point are in front of the person who pays, not buried in a clause.
