Small and medium businesses

e-Invoicing brings financial, operational and strategic benefits to businesses of all sizes, by simplifying and automating the exchange and processing of invoices.


The main benefit for invoice senders is faster payment from their buyers.

Benefits of e-Invoicing for businesses:

Getting started

Step 1

Check if your finance or accounting system is e-Invoicing enabled. See the e-Invoicing enabled software providers list. If they’re not enabled now, check if they’re planning to be.

Software providers

If you don’t use finance or accounting systems, or issue many invoices, there are FREE options with basic e-Invoicing capabilities available.

Step 2

Get your e-Invoicing enabled software provider to activate the e-Invoicing feature on your existing system.

Step 3

You're ready to e-Invoice. Start to send and/or receive invoices directly through your finance or accounting system.

Your access point provider and suppliers will want to record your NZ Business Number (NZBN). This number is the unique global identifier that ensures your suppliers’ e-Invoices reach you. If you don’t have one already, it’s easy and free to get one.

You’ll also want your buyers’ NZBNs for the same reason.

Cost to implement e-Invoicing

Most small business accounting and finance software provide free e-Invoicing capability. Ongoing costs are generally based on the number of e-Invoices you receive, with little or no cost to send.
