The Best Structure for Sending Invoice to Client Email Sample

When it comes to the world of freelancing or running a small business, sending invoices is crucial. This not only helps you keep track of your finances but also ensures that your clients pay you in a timely manner. One of the best ways to send an invoice to a client is via email. However, simply attaching a PDF file might not always be the most effective approach. Here are some tips on how to structure your invoice emails in a way that is professional, clear, and increases the likelihood of getting paid.

Subject Line

The first thing your client will see when they receive your email is the subject line. It is essential to make it clear and descriptive, so they know exactly what they are opening. Your subject line should include the words “Invoice” and a brief description of the project or service you are billing for. For example, “Invoice for website design project”.


Starting your email with a personal touch can make a big difference. Address your client by their name or title, depending on your relationship and level of formality. For example, “Dear [Client Name]”, “Hello [Client Name]”, or “Good day, [Mr./Ms./Dr. Last Name]”.

Opening Paragraph

Begin your email by thanking the client for their business and including your invoice number or any relevant information such as the date the project was completed. This ensures that the client can quickly identify the invoice and make the necessary payments without delay.

Body Paragraph

The body paragraph should include a breakdown of the services you provided, the amount owed, and any calculations that went into it. Be specific about what tasks were completed, how many hours were worked, and the hourly or flat rate you agreed on with the client. Try to avoid using jargon or confusing language, and make sure to double-check your math. Including a due date for payment in this section can also be helpful.

Call to Action

Conclude your email with a clear call to action. Politely request that the client pays the invoice and provide instructions on how they can do so. This may involve providing a link to an online payment portal or providing wire transfer information. Make sure to include all available payment options, contact information if they have any questions or concerns, and a reminder of the due date.


End your email with a professional closing, such as “Sincerely,” “Best regards,” or “Thank you for your prompt payment.” Then include your name, business name, contact information, and any other relevant details such as your tax ID number or business registration number.

By following these steps, you can increase the chances of getting paid faster and build a positive reputation as a professional and organized freelancer or small business owner.

Sending Invoices to Clients: Top Tips

When it comes to running a business, sending invoices is one of the most important tasks you’ll undertake. You need to ensure that your clients receive these bills in a timely manner and that all the necessary information is included to avoid payment delays or misunderstandings. In this post, we will explore some top tips for sending invoices to clients via email.

1. Personalize Your Invoices

Your invoices should not look like generic templates. They should be personalized with your company logo, company name, and contact information. This makes your brand recognizable and helps to build a professional image. Include the client’s name and address, along with a personalized message or greeting. Personalizing your invoices shows your clients that you care about their business and sets you apart from your competitors.

2. Provide a Clear Payment Schedule

Your invoice should include a clear payment schedule, including the due date, the amount due, and any terms that apply to the payment. This ensures that there is no confusion about the payment terms and the client knows exactly what to expect. Clearly outlining the payment schedule also helps to avoid late payments and misunderstandings with your clients.

3. Use a Professional Invoicing Software

If you have a high volume of invoices to send out, it is worth investing in a professional invoicing software. These software programs can track invoices, generate payment reminders, and provide real-time updates on outstanding payments. Using a professional invoicing software streamlines the invoicing process, saves you time and generally ensures that there are fewer errors or missed payments.

4. Keep It Simple and Clear

Avoid using jargon or complicated terminology when creating your invoices. Keep it simple and clear so that the client can quickly understand what they are paying for. Make sure that all the relevant information is included, such as the product or service description, the unit price, and the quantity. Avoid using vague terms like ‘miscellaneous’ and make sure that you use precise language.

5. Follow Up on Overdue Payments

If a client has exceeded the payment due date, it is important to follow up with a payment reminder. A polite email or phone call can be an effective way to remind clients of their outstanding balance and encourage prompt payment. Try to maintain a friendly and positive tone and be clear about the consequences of late payment. If necessary, you may need to involve a debt collection agency.

Overall, invoicing can be a complex and challenging aspect of running a business. However, by following these tips, you can make the process smoother, easier, and less stressful for you and your clients.

FAQs About Sending Invoice to Client Email

What should I include in my invoice email?

Make sure to include a professional greeting, the invoice number, a brief description of the services rendered, the total amount due, payment due date, and any payment methods accepted.

Is it better to send the invoice as an attachment or within the body of the email?

Either way is fine, but attaching the invoice in a PDF format is the most professional and secure method. It ensures that the formatting remains intact and eliminates the risk of information being altered inadvertently.

What should I do if the client doesn’t receive the invoice or I receive an error message?

If you receive an error message, wait a few minutes and try again. If the problem persists, contact your email service provider or your client’s IT department. In the meantime, you can also send the invoice through a different platform or method, such as sending a link to a secure payment website.

Can I customize my invoice templates with my company logo and branding?

Absolutely! It’s always a good idea to include your company logo and branding on your invoice templates. It helps to maintain consistency and professionalism across all customer communications.

When should I follow up on an unpaid invoice?

Generally, it’s best to send a polite reminder email a few days before the due date. If the invoice remains unpaid after the due date, send another reminder email and follow up with a phone call or an in-person visit if necessary. Be persistent, but always remain courteous and professional.

What payment methods should I offer my clients?

Offering multiple payment methods, such as credit card, debit card, PayPal, and direct deposit, can increase the probability of timely payments. Also, make sure to clearly outline the payment methods accepted on the invoice and include instructions on how to use each method.

What should I do if a client disputes an invoice?

First, try to understand the client’s perspective and address their concerns in a calm and rational manner. If there was a mistake on the invoice, correct it immediately and apologize for any inconvenience. If the client still refuses to pay, seek legal advice and consider sending a demand letter or taking legal action as a last resort.
