An invoice email is the most popular method of sending an invoice these days, especially among freelancers and small businesses - instant delivery with no unexpected delays is an undeniable advantage of email invoicing. 

In this article, we will talk about invoice email templates, discuss tips on how to write an invoice and have it paid as soon as possible, and introduce special services to help you with emailing an invoice easily.

How to Write an Invoice Email

Here are a few tips that will come in handy and ensure you get paid on time.

  • Make it professional, short, and simple. An invoice email should be nothing more than that - an invoice email. There is no need to write about anything else. Respect your time and the time of your client - thank them for their cooperation and write that you have attached the invoice.
  • Don’t forget about the subject line. It is better to include the invoice number and the due date in the subject line. Otherwise, your client may not even realize that you have sent them an invoice and could leave the message for later.
  • Include a brief description of your work, your rate, and information related to any other expenses. Your client must know exactly what they are paying for. Nobody likes surprises here.
  • It is better not to include your invoice in the body of the email but to attach it, preferably as a PDF. It is more likely to be compatible with the device and operating system they are using.
  • Even if you use an invoice email template, take a few moments and personalize it. Write a personal greeting and include a sentence or two about your work. Your client will definitely be glad and see that you have put in the effort and time to write them personally.
  • Use special services like Finom. They will save you time and protect you from accident typos or mistakes in your emails.

How to Write a Good Cover Letter for an Invoice Email

We have recommended keeping your invoice email simple, short and professional. However, if you have been working with the client for a long time or the project was complicated, you may wish to write a cover letter for your invoice. There might be information about your rates, whether or not you are going to change them in the future, the cost of each part of the project (ingredients for the final product). 

It is a good idea to include your contact information and the dates when you were working on the project. If you know your client really well, you may end the message with some personal things like thanking them for their trust and your hopes to continue working with them in the future.

Eight Elements of an Invoice 

The invoice email is a crucial part of your business. It is not only an instrument to ensure you get paid on time but also a way of keeping your communication friendly and professional. A correctly written invoice gives you and your clients a chance to have a long and mutually beneficial partnership. Here are eight things you should remember to include when writing an invoice email:

  • The name of your business logo
  • The invoice number and date
  • Customer info: full name and contacts
  • Amount to be paid
  • Due date
  • If an invoice doesn’t have a link, there should be clear payment instructions
  • A shortlist of the products or services the client is to pay for
  • Terms and conditions of the preferable payment method.
