Include an easy-to-read attachment in PDF, CSV, or XML format, and proofread for any errors or discrepancies.

An invoice email is an email sent to request payment from a client, outlining the services provided and attaching the invoice document. In addition, it can be used as a reminder or follow-up for pending invoice payments.
A well-written invoice email can improve cash flow management and relationship with clients.
Essential elements in an invoice email include

The structure of an invoice email resembles typical email formats, comprising a subject line, opening, content, conclusion, and any relevant attachments.
Let's break down how to write each section effectively.
The subject line is the first thing your recipient will see when receiving your invoice email. So, make it straightforward and informative.
A helpful invoice email subject line should summarize the purpose at a glance and be searchable. Consider the terms your client might use to locate your email in their inbox, such as invoice number or business name.
To elaborate, include the following information
For example, an effective subject line could be:
Next, start your invoice email on a courteous and professional note. Address your client, show appreciation for their trust in your product or services, and summarize that you are sending an invoice for the work you recently completed for them.
For example, a good opening line could be:
The body of the invoice email should explain the primary details about the invoice and payment terms, including
…Please find attached invoice #123, which is 2,000 USD.
The payment can be made via bank transfer to the following account:
Bank: ABC Bank
Account Number: 1234567890
SWIFT Code: ABCDUS33
Kindly include the invoice number in the reference field.
The payment is due by 15 April. Your adherence to this date is greatly appreciated
If you have any questions or concerns about the invoice, please contact John Doe at john@webdesign.com or (123) 456-7890.
Please note that a late fee of 5% will be applied if the payment is not received by the due date.
Each invoice email should include its corresponding invoice document. This benefits both parties for several reasons:

The final touch is to close an invoice email courteously and express your hope for future collaboration.
For example, write:
Followed by your signature, name, or business name.
Discussing money can be tricky. You want to convey that you appreciate the client’s business but also that you expect them to pay on time and according to the agreed terms.
If you want to keep both the cash flow and the good impression, these are some things to keep in mind when crafting your invoice email.
Avoid industry jargon and colloquial language since they make your email hard to follow and unprofessional.
Instead, use simple, straightforward, and polite language that outlines the purpose of your email, which is to request payment.
While it’s all good to have a standard template for your invoice emails, adding a touch of personalization shows that you care about your client.
For example, you can:
And while personalization and appreciation matter, keep it concise and to the point.
A missing zero is worth a thousand or even more. Losing a digit not only scrambles an invoice amount, but you can lose trust, too. Likewise, other errors.
Before sending your invoice email, ensure thorough proofreading to catch any spelling, grammar, punctuation, and number errors. Details about your payment method and terms, such as your account number, are as crucial.
Moreover, ensure that you have attached the correct invoice document that matches the information in your email. Your client might question your credibility or delay the payment if there are any discrepancies.
Lastly, are you sending it to the right recipient? The correct email in the “To” field will save much hassle. And do you need to CC your accountant? Catch that too.
💡 Tip: A plug-in like Grammarly or Hemingway can help with writing quality.
An easy-to-read attachment that helps people and software like invoice OCR tools or accounting systems understand the information is as important.
Choose PDF, CSV, or XML formats for easy downloading, printing, and uploading.
The easiest way to choose is to ask your customer if they prefer specific file types, like CSV or XML. Otherwise, go with PDF.
Avoid using Word Documents or images as they can cause formatting issues or data loss.

There's no single right time that applies to every scenario, as different situations require different approaches. However, it's generally best to send the invoice email promptly after completing the work. This helps ensure the client has all the payment details needed and is aware of the deadline from the outset.
Dispatching a reminder before the due date is also useful. Since recipients may receive a high volume of correspondence daily, an invoice could get lost in the shuffle. One or two weeks' reminder before the due date is common practice.
Sending invoices to customers by email is a common way to request payment. However, there are faster, easier, and more efficient alternatives, including:
