Invoice email templates

Professional email copy for sending invoices, reminders, and thank-you notes.

The email wrapping your invoice matters — a clear subject line and brief message get faster payment than a bare attachment.

InvoyFlow lets you set default email templates and customize the message per invoice.

Step by step

Subject line

Invoice #[number] from [Business] — Due [date]

Opening line

Brief and professional: "Please find attached invoice for [project]."

Payment instructions

Link to pay online prominently above the fold.

Reminder tone

Friendly first reminder; firmer at 14+ days overdue.

Thank you note

After payment: "Thank you — receipt attached."

How long should the email be?

Three to five sentences. Clients want the invoice and pay link, not an essay.

Should I attach the PDF?

Yes — attach PDF and include the online payment link in the email body.
