The Anatomy of an Invoice: What It Must Contain

When you first start creating invoices, it can certainly be overwhelming. This is especially true since many invoices will differ depending on the work you’ve done, as well as the requirements of you and your client. However, there are several key elements you need to include in every invoice.

You can think of these as your invoice’s ‘baseline’ – the most important information for both you and the recipient. By making sure you include these in every issued invoice, you’ll have a good template to build from.

In this article, we’ll show you the eight key elements you’ll need to show on every invoice. We’ll also touch on how you can make this process easier by using a solution such as Hiveage. Let’s get started!

8 Elements Every Invoice Must Contain

Of course, your invoice will usually contain every element required by your clients, and this will sometimes be dictated by geographical or government-specific laws and regulations. However, our first element is firmly grounded in common sense.

1. Clearly Mark Your Invoices as Such

This first item is an easy one. This simply means including the word “Invoice” on your invoice. While this could seem obvious, it’s actually very important to make its purpose clear. For example, clearly marking your invoice will avoid situations where people may confuse it for a receipt, statement, or estimate.

As you read through these elements, remember that your main goal should be to get paid as quickly as possible once an invoice is issued. As such, you’ll often notice that your template will need adjustment in some way if payment times are overly long.

2. Add a Unique Invoice ID Number

An invoice ID number is a unique string that identifies a specific invoice. These usually have a predetermined format, including a prefix and a series of numbers. Invoice IDs are most commonly associated with recurring billing.

However, they’re still extremely important to include, even on one-off invoices for your own records and your clients’. By assigning a unique identifier to each invoice, you can easily refer to previous invoices and it makes it much simpler to track the work you’ve done with different clients.

3. Include Accurate Cost Amounts

Naturally, you need to tell your client what they need to pay. However, alongside the total sum, you should also break down the costs into individual amounts for each aspect of the work you’ve done.

For instance, if you’ve designed both a website and logo for a client, you should outline what each task cost. This will help them get a clearer idea of what they’re paying for and how the final figure was calculated.

4. Make the Payment Terms Clear

In addition to telling them what they should pay, you also need to make it clear how they should do it. You can use this to inform them of what payment methods you accept and when you want them to pay.

Being clear at this stage will help avoid caused by uncertainty or delays in payment. As we mentioned, the easier it is to pay an invoice, the quicker you’ll receive the money.

5. Supply Payment Details

Of course, you also need to give your client the details they need to complete the payment. For example, this could include your account details and sort code, or your PayPal address.

As before, providing all the information and details at this stage will make it easier for your clients to complete the payment on time. It also ensure each payment is completed according to your requirements.

6. Include All Relevant Dates

Your invoice also needs to contain accurate date information. This includes the following:

  • Supply date: When you delivered the service or product to the client.
  • Invoice date: When you sent the invoice.
  • Payment date: Deadline for paying the invoice.

It’s naturally also important you make relevant dates completely clear, in order to avoid misunderstandings.

7. Include a Summary of the Invoiced Services

You should include a description of what exactly the invoice is for. The purpose of this is to clearly outline which services or products you have provided to the client.

Make sure you’re as specific as possible here, as this will help those responsible for processing the invoice to know exactly what they’re paying for. Avoid vague comments such as “Provided various services” and focus on the actual deliverables.

8. Provide Personal Information for You and Your Customer

Finally, you should make sure to add all relevant personal information about both you and your customer. For you, this includes your name, address, and contact details at a bare minimum. When it comes to the client, you should at least include their company name and address.

You can add additional information as well, as appropriate, such as tax ID numbers. However, avoid adding unimportant filler, as this could make the invoice difficult to read.

How to Easily Create and Manage Invoices

Even though there are a fair few things you need to consider, creating a functional invoice doesn’t have to be difficult. To make life easier for yourself, you should consider using dedicated software like Hiveage for its invoicing capabilities.
