10 Important Things on How to Write an Invoice for Freelance Work

Pedro Barros, an expert in managing contractors at Remote, notes that mistakes on invoices can potentially cause payment delays for you and appear unprofessional to your clients. To preserve your good reputation, pay attention to these things to include in a freelancer invoice.

1. Contact Information

Contact details show that you and your client are based on trust. They commonly include the name of the business, address, email, and logo. Always remember to keep everything professional, including your full name and representative logo. Without them, your client will struggle to communicate with you.

2. Information About the Client

Your invoice should look professional. So, it needs the receiver’s contact details, namely the individual’s full name or the company’s name, email, phone number, and address. 

The complete information acts as a sign of respect that you have been doing business with them. Also, it helps you to be organized, especially if you have many clients. 

3. Clear Work Description

Surely, you wish to be rewarded according to your effort and agreement with your clients. And excluding your work description might guide them away from the accurate amount of your payment. So, make sure you render each work you have completed, including the dates of completion and rates.

4. Extra Expenses

The components of how to invoice as a freelancer apparently can include unexpected expenses during your work progress, like the cost of travelling to meet your clients. This ensures that your time and effort are properly rewarded. You can arrange a list in a separate section in the invoices to stand out for your clients to see.

5. Invoice Date and Number

There will come a time when you need to return to your past invoices. Without the date and number, you will struggle to find the one you wish to see or track payment due dates. So, assign a unique series of numbers to identify every invoice and its dates accordingly, right in the header.

6. Due Dates

To prevent delayed payment, due dates must be included in invoices to give clients a heads-up. In addition to that, this component can give you the right to follow up to remind them of their obligation to pay for your service or product.

7. Options for Payment

Clients complete the payment through certain services, such as credit cards and PayPal. So, the more options you have, the more convenient it is for your clients to complete their responsibilities and the smoother your payment. For example, you may create a hyperlink to direct your client to your PayPal account.

8. Payment Terms

Apart from due dates, payment terms undoubtedly ensure no late payment, which potentially would stress you out. Usually, the terms allow clients to complete the payment within 30 days. If the clients miss the date, this term gives you the right to charge them additional fees, like late fees.

9. A Specific Section for Notes

In working, unpredictability always happens, like a client who suddenly requests the project to be finished within two days, not a week as agreed at the beginning.

For this kind of occurrence, rather than being off-the-record, you actually can elaborate on it in the note section. It allows you to receive additional payment for the rush or overtime.

10. The Total Amount for Your Work

This is the most important component of how to invoice as a freelancer. Without the accurate amount, you might get in trouble, like having to argue with the clients about tax laws or other necessary tax fees. So, make sure you familiarize yourself with everything and calculate properly before deciding on the final amount.
