1: What is an invoice?
When you’re just starting out in business, with only a few invoices to track, invoicing is pretty straightforward. But as your customer numbers grow and the volume of work grows, it can become hectic and messy. And it can start to eat into the evenings and weekends you used to enjoy.
If you feel this way, you’re not alone, and that’s why we’re here to help. We know that once you’re in business, you need to get paid. Fast. And very often, being paid on time is essential to a business’s cash flow and its ability to survive and grow.
So why do invoices matter?
Your invoices are one of the ways you communicate to your customers. They show the goods or services you’ve supplied and what you’re owed in return. An invoice shows how much your customer has to pay, when the payment is due, and the ways they can pay.
Your invoices are also tax documents. You’re required to keep copies to show how much you earned – and if you're GST registered, how much tax you’ve collected.
How invoicing works – from start to finish
There’s more to invoicing than you might think. It’s a process that begins when you take on a job and only finishes when the money comes in the door. There are quite a few steps along the way.
No-one wants to be stuck in the office doing accounts, so automating as many steps as you can you can really helps.
Details of what goes on an invoice
Some of the details in an invoice stay the same in each one you send and can be set up in a template that you use each time. For the content that varies, you can create placeholders in your template.
The payment terms and methods of payment you offer may change occasionally. If they do change for a particular customer or job, you’ll need to remember to alter them.
Here's more detail about what goes into an invoice.
- Logo: Your business logo if you have one.

Payment terms example
Write your payment terms in plain English on your invoice and make it clear how you prefer to get paid. Here’s an example:
"Create an email address specifically for dealing with invoicing and accounting. For example, set up firstname.lastname@example.org and send all your invoices from that email. It has a psychological impact when it comes to asking to be paid."
