How to Email an Invoice to Your Client

Downloading the PDF First

Before you can email your invoice, click "Download PDF" to save the file to your device. Double-check the PDF for accuracy — verify the client name, amounts, due date, and your payment details. A quick review now prevents awkward correction emails later.

Attaching to an Email

Open your email client and create a new message to your client. Attach the PDF file and keep the email body concise and professional. Name the attachment clearly (for example, "Invoice-042-ClientName.pdf") so the recipient can identify it immediately in their downloads folder.

What to Write in the Email Body

Keep it short: greet the client, state the invoice number and amount due, mention the due date, and include your payment details or a link. For example: "Please find Invoice #042 attached for $1,500, due by May 15. Payment can be made via bank transfer to the details on the invoice."

Following Up on Unpaid Invoices

If the due date passes without payment, send a polite reminder. Reference the invoice number and original due date, and reattach the PDF for convenience. A second follow-up a week later should be firmer in tone. Keeping a paper trail of all communications protects you in disputes.

Frequently Asked Questions

Can I send invoices directly from InvoiceGen?
InvoiceGen currently generates PDFs for you to send through your own email client. This gives you full control over the message, subject line, and any personal touches you want to add.
What subject line should I use when emailing an invoice?
A clear format is: "Invoice #[number] from [Your Business] — Due [date]". This tells the recipient exactly what the email contains and when action is needed.
Is there a way to get read receipts for emailed invoices?
Read receipts depend on your email client, not InvoiceGen. Most email apps (Gmail, Outlook) support read receipt requests, though recipients can decline them. For high-value invoices, consider using a tracked email tool.
