Invoicing built for Australian sole traders

Free plan available · No credit card required

Why we built Invio

Invio started with a simple frustration. Running as a sole trader, the tools available were either too basic - nothing more than a PDF template that still needed manual GST maths - or far too complex, bundling full payroll, bookkeeping, and multi-user accounting into something that cost more per month than the problem warranted.

What was missing was the middle ground: something that handled quotes, GST-ready invoices, payment tracking, and automated follow-up, without requiring an accountant to set up or a monthly subscription that outweighed the benefit. Invio was built to be that tool - NZ-first from the ground up, not a global product with NZ support bolted on.

The goal has stayed the same since the first line of code: help sole traders and tradies get paid faster, with less admin, and at a price that makes sense for a one-person business.

Our core commitments

Five principles that shape every decision we make about the product and how we price it.

Genuinely free to start
No credit card required. Start invoicing immediately on the free plan - 5 invoices a month and unlimited quotes, with no expiry and no catch.
Flat, fair pricing
Pro is A$19/mo. Growth is A$59/mo. We promise not to raise the price of your subscription while it continues. The one exception is an introductory offer, which shows the price that follows it when you sign up (for example, A$5 a month for your first 3 months, then A$19).
Built for Australian tradies too
ATO-aligned GST tax invoices, BSB bank detail fields, and Xero/MYOB export. Not a generic tool bolted on for Australia.
Focused on getting paid faster
Automated payment reminders, clear payment status tracking, and a quote-to-invoice flow built so follow-up happens without chasing manually.
Deliberately simple
Invio is not a tax service or full accounting suite. It does one thing well: quote, invoice, and get paid - without accounting bloat getting in the way.
