Hi {{Name}},

Just a quick reminder that invoice #{{InvoiceNumber}} for {{Amount}} was due on {{DueDate}}. If it slipped through the cracks, you can pay here: {{PayLink}}.

If a payment date is scheduled, could you let me know when to expect it?

Thank you for your attention—let me know if you need anything on my end.

Best,

If no reply in 2–3 days, move to a firmer date-demand email

Don’t threaten or escalate unless truly overdue
Don’t include full invoice history—focus just on current status
Keep it concise and positive for the first reminder
