Templates are only half the battle. How and when you send them matters just as much.
Your client may have dozens of invoices from various vendors. Include the number in both the subject line and body.
Start warm and friendly. Get progressively more formal. Never jump from a friendly nudge to legal threats.
Every reminder should include how to pay. A payment portal URL or bank details. Remove friction and you remove excuses.
9-11 AM gets the highest open rates. Avoid Mondays (inbox overload) and Fridays (weekend mindset).
If things escalate to collections, you'll need proof of reasonable reminders. Email creates that trail automatically.
You did the work. Asking to be paid on agreed terms is not pushy. It's running a business.
These templates work. But the hard part was never writing the email . It's remembering to send it.
