Steps for Writing an Invoice Email

Want to streamline your invoicing process and save time and money on printing and mailing costs? Sending invoices via email can be a convenient and efficient option.

Before diving into the specific steps of writing an invoice email, it’s essential to understand the benefits of sending invoices electronically.

Not only does sending invoices via email save time and paper, but it also allows for easy tracking and payment.

Plus, with electronic invoicing software, you can automate the invoicing process and request payments automatically.

1. Attach the Invoice to Your Email

First, before doing anything else, attach your invoice to the email you want to send out to your clients.

It has happened to many of us even more than once to send out an invoice email and forgot to attach the particular invoice. In cases like this, you will likely experience a delayed payment since you know you have to follow up with your client and send them an email again.

If you make it a habit to always have your invoice attached at the very moment you create a new email thread, then this won’t be an issue for you.

Before attaching invoices, make sure that your file is a PDF since that’s the most common format companies use to process invoices.

2. Write a Descriptive Subject Line

When sending an invoice email, it is important to include a clear and descriptive subject line.

An effective subject line for an invoice email should include the word "invoice," the invoice number, and a brief description of the goods or services provided.

A concise subject line, at most 50 characters, is recommended to ensure it is not truncated or overlooked. For example, "Invoice #123456 - Website Design Services" clearly and accurately conveys the content of the email.

By following these guidelines, you can create a subject line that is informative and attention-grabbing, which helps to ensure that your invoice email gets the attention it deserves.

 This will increase the chance that you will receive payment faster.

3. Keep Your Invoice Emails Simple but Professional

When you send an invoice email, it is a good idea to use a professional and visually appealing format for your invoice emails.

You can use a pre-designed invoice email template we will share with you in the next section, or create your own custom layout, but keep it clean and organized.

Use only a few colors or font styles since you don’t want your emails to look cluttered and unprofessional.

The key to creating simple but professional invoice emails is to focus on conveying the necessary information clearly and concisely while presenting the information in a visually appealing way.

By following these tips, you can create effective invoice emails that help you avoid late payments.

4. Use an Invoice Email Template

Invoice email templates are a convenient and efficient way to help you send invoices - especially if you work with multiple clients.

An email invoice template is a pre-designed structure that includes a brief text in the body of the email which will let the client know that your email is intended to request payment for the goods sold or services completed.

Here is a free email template with a proper invoice email message example that you can use to send an invoice to your clients:

Email Subject Line: {{Invoice number}} - {{Short Description of Services or Goods}} .

Hi {{client name}},

The {{services completed or goods sold}} have been completed(or delivered for goods) successfully.

In line with the work completed, I have attached the invoice as follows:

  • {{Invoice number}},
  • {{Services or goods sold}}
  • {{Invoice due date}}

Please contact me if you have any questions or concerns about the attached invoice.

Thank you for doing business with us.

Best Regards,

{{Your email signature}}

The likelihood of receiving payment will be higher with a short email subject line and concise invoice email message.

5. Follow Up with a Past Due Invoice Email

While sending a well-written and correctly formatted invoice email is the way to go, it's not always the case that the client makes the payment before the invoice due date.

This could happen because your client is too busy and overlooked your email, or the email simply wasn’t sent at the right time.

That’s why sending a follow-up email for past-due invoices is always important.

We created a past-due invoice email template for you to use if you are struggling with late payments:

Email Subject Line: Overdue Invoice Notice - {{Invoice Number}} for {{client name}}

Hi {{client name}},

This is a friendly payment reminder on the payment for invoice number {{number of invoice}}, for {{services completed or goods sold}}.

For your convenience, we attached the invoice again to this email, where you can find all the payment information.

If you still need to pay, please do so via one of the payment options provided in the pending invoice.

Looking forward to your payment and continuing to do business together.

Follow-ups on late payments highly increase the likelihood of you getting paid faster than not sending a follow-up invoice email.
