How to design and format an invoice​

Steps for formatting invoices

Step 1: Organize invoice information

In order to format an invoice, you must first gather all necessary information about your business.  Your business details include the full business name, logo, and contact information. 

You should also include your recipient’s contact information, name, business name if applicable and address.  

You must include the invoice date and payment due dates to ensure you get paid on time.  

Step 2: Make a clear header for invoices

The header of your invoice should clearly identify it as an invoice. Begin by placing the word “INVOICE” in bold lettering and a larger font size at the top.  Adding an invoice header not only adds a professional touch but also ensures that your customer immediately recognizes the purpose of the document.

Step 3: Include a billing summary in your invoice​

A billing summary provides a concise overview of the goods or services provided and their associated costs. Create a table with columns for item description, quantity, price or rate, and sub-total amount. 

Itemize the products or services provided by filling in each row with the relevant information.  

Step 4: Add applicable taxes & discounts​

Include any taxes or discounts in a separate section below the billing summary. Clearly state the tax rate, a description of the tax (e.g state or sales tax) and calculate the tax amount. 

Similarly, ensure that you clearly outline any discounts that apply and adjust the final invoice total accordingly. 

Step 5: Provide payment terms & methods ​

Clearly communicating your payment terms and methods on your invoice to customers is essential to ensure timely payment. 

You’d want to include a section on your invoice that specifies the payment due date, accepted payment methods like card payments, and any late payment fees or penalties. 

Step 6: Include additional information​

You may want to include extra information on your invoice to avoid confusion and protect yourself in the event of a dispute or non-payment.  Additional information could include the following:

  • Terms and conditions
  • Disclaimers
  • Payment schedules
  • Purchase order numbers
  • Project details
  • Any other special terms agreed on with your customer
