Invoice and payment reminder email templates
Getting paid without straining the relationship.
An invoice email needs the amount, the due date, the invoice number and how to pay, all visible without opening an attachment. Reminders work better when they stay factual: state what is outstanding and by how long, and ask a direct question.
3 templates
Invoice email
Sending an invoice so it gets paid without questions.
Payment reminder
A polite nudge as the due date approaches or just passes.
Overdue notice
A firmer message once an invoice is well past due.

Who these are for
Written with freelancers, agencies, small business in mind, and kept plain enough to send from a personal Gmail account without looking like a marketing blast.
Use this template in Gmail
Copy the HTML above and paste it into Mailplate, the free Gmail extension that inlines the CSS so the layout survives sending. Or edit the wording directly in the preview and insert it into your message.
