Table of contents

Welcome to the world of independent consultancy, where you get to call the shots, manage your own time and, most importantly, invoice your clients. Yes, drafting an invoice is a crucial part of your job. But don't worry, we are here to help you understand how to write an invoice in the simplest way possible.

Identify the necessary elements of an invoice

An invoice is more than just a bill. It's your ticket to getting paid on time and in full. But before you can create one, it's important to understand the necessary elements that make up an invoice:

  1. Invoice number: This is your invoice's unique identification. You may wonder how to write an invoice number—it's simple. It can be as straightforward as a sequential number (like "001", "002", "003"), or it can include letters and even the date.
  2. Your details: This includes your name, address, contact information, and if applicable, your tax identification number.
  3. Your client’s details: Remember to include your client's name, address, and contact information.
  4. Date: The date when the invoice is issued.
  5. Description of services: Here, you detail the work you've done for your client.
  6. Total amount: This is the total cost of your services. It's calculated by multiplying the rate of your service by the number of hours worked.

Now that you know what elements to include, it's time to choose a template that suits your needs. A quick Google search can provide you with numerous options. But here's a tip: the folks at Freshbooks and Paperbell offer some excellent templates that could save you some time.

In the next section, we will look at how to write a clear and concise item description, before we dive into calculating and including the total amount due. Are you ready to take your invoicing skills to the next level?

Choose the right invoice template for your needs

Alright, so we've got the basics down. The next step on our journey of how to write an invoice is picking the right template. While you could go old school and draft an invoice on a blank document, why reinvent the wheel when there are a plethora of templates out there?

Selecting the right invoice template isn’t just about aesthetics— it's about ease of use, functionality, and professionalism. The ideal template should be simple yet comprehensive, presenting all necessary information in a clear and easy-to-understand format. A good invoice template should allow you to:

  1. Personalize: Personalization doesn't just mean slapping your logo on the top. Your invoice should reflect your brand, from the choice of fonts and colors to the layout and design. It should look professional, and convey your brand's unique identity.
  2. Automate: The less time you spend on administrative tasks, the more time you have to focus on your work. Choose a template that automates calculations and keeps track of your invoices, so you don't have to.
  3. Organize: It should allow you to neatly arrange and present all the necessary elements of an invoice that we discussed earlier.

There are numerous free and paid invoice templates available online. You can make use of platforms like Raise and OysterHR that offer editable, professional invoice templates.

Remember, the goal is to make your invoicing process as efficient and smooth as possible. Once you've chosen the perfect template, you're ready to move on to the next step: writing a clear and concise item description. Let's get to it, shall we?

Write a clear and concise item description

So, you've got your invoice template. Now, let's fill in the details. A significant part of learning how to write an invoice lies in crafting clear, concise item descriptions. You don't want your clients scratching their heads, trying to figure out what they're being billed for, right?

Here’s the deal: vague, ambiguous descriptions do nothing but create confusion. Your item descriptions should be as transparent as possible. This is where you detail the services you provided, the products you delivered, or the time you spent on a project.

Be specific: Instead of writing "consultation services," specify the kind of consultation provided. Was it a marketing strategy consultation? A product development consultation? Make it clear.

Include dates: If your service extends over a period of time, include the start and end dates. This gives your client a clear picture of the timeframe the invoice covers.

Use understandable language: Keep the jargon to a minimum. While you might be familiar with all the industry terminology, your clients might not be.

Break it down: If a project includes different components, break them down. This not only makes your invoice more detailed but also gives your clients a better understanding of all the work you've done.

Remember, your item descriptions are a reflection of your work. Taking the time to write clear, concise descriptions shows your professionalism and attention to detail.

Calculate and include the total amount due

Now that we've detailed the services provided, it's time for the moment of truth: calculating the total amount due. This is a critical step in learning how to write an invoice. It's where you'll show the value of your work.

Here's the step-by-step process:

  1. Detail the costs: Next to each item description, you should list the cost. If you charge by the hour, indicate the number of hours worked and your rate. If you charge per project, list the agreed-upon price.
  2. Add it up: Tally up all the costs for each item or service to get the subtotal.
  3. Include any discounts: If you've offered a discount to your client, subtract that amount from the subtotal.
  4. Add taxes: Depending on where you and your client are located, taxes might need to be included. Be sure to research and comply with any local tax laws. Add the appropriate tax amount to the subtotal.
  5. Grand total: The final step in the calculation is to provide the grand total. This is the amount your client is required to pay. Make sure this number is bold and easy to find on the invoice.

When it comes to freelance work or consultancy, the importance of clear and precise invoice calculations can't be understated. It's not just about getting paid; it's about maintaining trust and transparency with your clients.
