How to create an invoice

An invoice is a document you give to your customer or buyer to collect payment from them. It will contain their details, your company details, what goods or services they need to pay for, the amounts, whether there is VAT to pay, the date it is due, how to pay and the payment terms.

There are several ways you can create an invoice but all will include the same information.

A step-by-step guide on how to create an invoice

Whether you do it yourself on Word or use invoicing software, when you create your invoice follow these steps:

1. **Add a logo to your invoice**

Adding your logo and colours to your invoice not only makes it look professional it helps raise brand awareness and provides cohesion across the entire sales and marketing process.

2. **Use an invoice numbering system**

On every invoice you should include a unique number which helps both you and your customer keep track. Choose a system that works for you e.g., alphanumeric based on date, job number, customer initials etc. to avoid any confusion.

3. **Create a professional header**

As well as your logo, include name, address and contact details of your business. You should also include your customer’s details, address and contact information. If you’re a limited company and or VAT registered you should add your registration numbers too.

4. **Include dates**

Add the date the invoice is issued, date goods or services were provided and date(s) payment is due.

5. **Description of goods and services**

Provide a detailed description of goods and services and if applicable an itemised breakdown. For example, you should include the price of each unit, the quantity purchased, the sub-total, grand total and VAT if applicable. With services you should include the time spent on each service, the cost per service or hourly charge depending on how you calculate any fees.

6. **Tax and payment details to include**

You should provide details of any VAT on each item if applicable, the total excluding VAT, the % VAT charged and the final total inclusive of VAT.

You should also include:

  • Date of invoice issue

Five ways to create an invoice

If you need some help getting started with invoicing here are five of the most popular ways to create an invoice.

1. How to create an invoice in Google Docs

Google Docs provide an easy-to-share option for creating an invoice document. With easily downloadable templates you can quickly generate an invoice, or start from scratch and create your own. To use a Google Docs invoice template:

  1. Log in to your Google account and go to your Google Drive.
  2. Click the “+ New” button and scroll down to Google Docs in the drop-down menu. Click the arrow next to it and select “From a template.” This brings you to the templates page.
  3. Type “invoice” in the search bar on the templates page. A selection of invoice templates should appear in the results. Review the choices and select the best invoice template for your business.
  4. Fill out the new page with the template you selected. This includes custom entry fields with things like company name, address, phone number, email, logo, payment terms, and official payee name for receiving payments.

2. How to create an invoice with a free invoice generator

If you’re not using any of the above programs or their templates, you can use a free invoice generator. Square and a handful of accounting software services, like QuickBooks, offer professional invoice samples. To use a free invoice template from Square, follow these steps:

  1. On the Square invoice template page, select the colour and file format for the invoice you want to create.

  2. Enter your email address in the pop-up and the template will open in a new tab. If you don’t see the template pop up immediately, check your pop-up blocker settings for Square’s website.

  3. Add in the entry fields for your business name, customer name, sent and due dates, the items, and the amounts.

  4. Download your invoice and send it to your customer as an attachment.

3. How to create an invoice in Microsoft Word.

There are a variety of easy, professional-looking templates in Word. Creating invoices this way can work well, especially if you are most familiar with the software. However, it can be also a bit cumbersome. This is especially true when it comes to getting paid. Printing and sending paper invoices via snail mail can have a long turnaround time.

And even if you’re sending a Word file via email, you have to figure out the best method for customers to pay you. Usually this involves using a third-party system (like an online payments app) or having them send along a physical check. But if you still prefer to create invoices in Word, here’s how you do it:

  1. Choose from Word’s invoice template under New in the File menu.

  2. Look for the Invoice icon in the dialogue box (usually on the left-hand side), and select the invoice type that best fits your needs.

  3. Set a professional header that contains your business’s contact information: business name, mailing address, phone number, email, and business logo.

  4. Put in the client’s information (usually underneath and on the opposite side from your company’s contact info). And be sure to include the name of the business, mailing address, phone number, and email.

  5. Include the unique invoice number, date the invoice was prepared, and a payment due date.

  6. Indicate the payment method to set clear expectations.

  7. Break down products or services into line item descriptions, along with charges associated with each. Calculate the total, including any applicable sales tax, delivery fees, etc. It’s helpful to put the grand total in bold font so that it clearly stands out. Then, download your invoice.

4. How to create an invoice in Microsoft Excel.

Excel offers a variety of clean, easy-to-use invoice templates, depending on your needs. However, you may run into the same logistical challenges as sending invoices via Word.

  1. Open a new workbook from the File menu and then look for the Invoice icon in the dialogue box (usually on the left-hand side).

  2. Choose the invoice type that best fits your needs — from a basic product invoice to invoices for specific types of services.

  3. Fill out the custom entry fields with things like company name, address, phone number, email, logo, customer ID (if applicable), payment terms, and official payee name for receiving payments.

  4. Be sure to include a unique invoice number, a description of products or services, and the client’s information.
