How to Write a Strong Invoice Email

When you’re emailing an invoice, there are a few steps to follow to make sure that your client knows exactly what they’re paying for and how to pay you.

Personalize It

Your invoice email should be addressed to the client by name. This is a simple way to make your email stand out from any other automated messages they may receive. Here are a few ways to personalize your invoice email:

  • Include the name and brief details of the project.
  • Provide a link to a folder with past invoices or payment history.
  • Add a personal note thanking them for their business.

Use a Clear Subject Line

Your subject line should be clear and concise. It should let the client know that they have an invoice to pay. Here are a few examples of how to write a clear subject line for your invoice email.

  • INVOICE: [Your Name] – [Date]
  • Invoice # [123456]: [Your Name] – [Project Name]
  • Payment Requested: [Your Name] – [Project Name]
  • [Your Name]: Invoice for [Date]

Include the Amount Owed & Due Date

Be clear about how much the client owes you and when payment is due. This will avoid any confusion on their part and make it more likely that you’ll receive timely payment. You can include this information in the body of your email or as an attachment.

Use Simple, Clear Language

Your invoice email should be easy for the client to understand. Use simple language and avoid any industry jargon. If you need to use abbreviations, be sure to explain what they mean.

It’s also important to proofread your invoice email before you send it. Check for any errors in grammar or spelling. These can make your email look unprofessional and lead to confusion on the client’s part.

Attach Your Invoice More Than One Way

When you send your invoice, be sure to include it as an attachment. This way, the client can download and save it for their records. You should also include a link to the online invoice so they can access it later.

By including both an attachment and a link, you’re giving the client the option of how they’d like to view and save the invoice. This can be helpful if they’re short on time or if they prefer to access their invoices online.

Make it Easy for Customers to Pay

The whole point of an invoice email is to get paid. To make it as easy as possible for your client, include all relevant payment information in your email, as well as how you accept payments and any deadlines or late fees that may apply.

You can also add a link to your online payment portal or a button that they can use to pay the invoice with a credit card. By making it easy for them to pay, you’re more likely to receive timely payment.

Other Tips for Emailing an Invoice

  • Include a thank-you note. A simple thank you can go a long way in building a relationship with your client.
  • Don’t be afraid to follow up. If you haven’t received payment within a few days of the due date, reach out to your client and ask if they need any help with the invoice.
  • Double-check that all your invoice details are correct. 61% of past due payments are due to incorrect invoices, so accuracy is key to getting paid on time.
  • Consider using a service. If you’re tired of chasing down payments, it may be worth using an invoicing and payments service. These services can automate the process of sending and tracking invoices.
