What Your Client Receives When You Email an Invoice

Clicking "send" on an invoice feels like the end of the job, but it's worth knowing exactly what lands in your client's inbox. The invoice email is deliberately short. It tells the client an invoice exists and what it adds up to. What it leaves out is just as important for getting paid.

The Email Is a Summary Card

The email has the subject "Invoice" followed by your invoice number, for example "Invoice INV-0042". The body is a small card with a heading, a line saying the client has received an invoice from you, and three rows:

• Date: the invoice's issue date
• Due date: when payment is due
• Total: the invoice total with your currency symbol and two decimal places

The "from" line uses the text in the From field of your invoice. Whatever you put there, such as a business name or a full address block, is what the client sees as the sender in the body.

What It Doesn't Include

There are three things it doesn't include, and each one affects what you should do:

• No PDF attachment. The email contains the summary only, not the document.
• No link to the invoice. There's no button to view the full invoice online.
• No reply path to you. The email comes from a no-reply system address, so if the client hits reply, the message won't reach you.

On its own, then, the email works as a notification. It tells the client the amount and the due date, but it doesn't give them the line items, your payment details, or a way to ask a question.

Pair It with a Share Link or the PDF

The simplest way to complete it is to send a second message from your own email account, so replies come to you. Include one of these:

• A share link. It shows the full invoice in the browser, can have a password and an expiry date, and records when the client opens it.
• A client portal link for clients you invoice regularly. They can see all their documents, leave comments, and approve estimates in one place.
• The PDF, downloaded from the editor. When you're signed in, it includes a QR code that opens the online version.

If you accept card or bank payments through a payment page, add the URL to the invoice's payment link field so it appears on the invoice your client opens.

A Client Email Is Required

The send button only works when the invoice has a client email address. Without one, the editor asks you to add it first. When you're signed in and the invoice is saved, a successful send also adds a "sent" entry to the invoice's audit trail, recording the address it went to. That's useful later if a client says they never received it.

Reminders Are Different

Payment reminders, whether sent automatically or in bulk, use a different template. Their subject changes to "Overdue: Invoice …" once the invoice is overdue, or "Reminder: Invoice … is due soon" before that. The body shows the remaining balance rather than the original total, so a partly paid invoice asks only for what's still owed. Like the invoice email, a reminder works best when the client already has a share link or portal link to open.

The Takeaway

Treat the invoice email as an official notification that tells the client an invoice is waiting and how much is due. Send the document itself (a share link, a portal link, or the PDF) from your own email account, so the client has everything they need to pay and can reply to you directly.
