Why confirm a payment at all
A short confirmation closes the invoice on both sides. The client's accounts team can mark it paid without wondering whether it arrived, and you have a dated note of what came in and how. It also catches mistakes early: if the amount is wrong, the client hears about it the same week rather than at the next invoice.
Part payments and overpayments
- Paid in part: say what is left, and when it is due. A thank-you that skips the balance reads as if the invoice is settled. The email states the amount still owed and its due date, and says the payment details have not changed.
- Paid too much: say by how much. The extra belongs to the client. The email tells them how much it is and offers it back or as a credit against the next invoice, so they do not have to ask. If there may not be a next invoice, I recommend offering to send it back.
- Amount owed left blank. The email confirms what arrived and says nothing about a balance. Fill it in if you want the email to say the invoice is paid in full.
An email is not a receipt
This email thanks the client and confirms the payment. Some clients also need a receipt, usually for an expense claim or a grant report. Invoice vs receipt covers what a receipt should say and how to make one in the invoice generator. If you attach one, tick the box and the email mentions it.
What this generator does not do
- It does not send anything. It writes the email. You copy it, or open it in your own email app, and send it from there.
- It cannot attach the receipt. An email link can carry a subject and a body but not a file, so attach the PDF yourself before sending.
- It does not keep anything. Nothing is written to your browser's storage and nothing you type is sent to us.
