What information should be on a contractor’s invoice?

An invoice helps you get paid for your contracting services. Here’s what you should include on the invoice:

  • An invoice number
  • Your name and contact details
  • The name and contact details of the client you’re invoicing
  • The date the invoice was created
  • The due date
  • A description of the services you’re billing the client for
  • The amount due, including VAT or GST, if applicable
  • Information about how the client should pay you, for example bank transfer details

If you’re billing by the hour, you should also attach a timesheet showing the hours you’ve worked.

What are the best invoicing practices for contractors?
  • Ask your clients what information they need to be able to provide payment by the due date. This will help avoid confusion and payment disputes.
  • Make sure all the information on the invoice is correct. Invoice software will help you fill in all the necessary details. Your clients, services and contact details are saved and automatically added to your future invoices.
  • Send invoices early to improve your chances of getting paid on time. The client might have a cut-off date, for example the 5th of each month, so make sure to submit invoices for the previous month before that date.
  • Use invoicing software to keep track of your invoices and overdue payments. If you don’t receive payment by the due date, it’s a good idea to send a reminder promptly. That’ll also bump your invoice to the top of the pile.
