Invoice reminder email templates for small business
Use these templates for invoice automation. The trick is to keep reminders specific, polite, and connected to a real human follow-up when payment is still late.

Due today
Subject: Invoice {{invoice_number}} is due today
Body: Hi {{first_name}}, invoice {{invoice_number}} for {{amount}} is due today. Here is the payment link again: {{payment_link}}. Let us know if you have any questions.
First overdue reminder
Subject: Invoice {{invoice_number}} is past due
Body: Hi {{first_name}}, just following up because invoice {{invoice_number}} was due on {{due_date}}. You can pay here: {{payment_link}}. If something looks off, reply and we will review it.
Human follow-up task
