Invoicing built for New Zealand sole traders

Invio is a New Zealand-built invoicing app for sole traders, tradies, and freelancers - made by NullGlitch, a New Zealand web and software studio.

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 NZ$19/mo. Growth is NZ$59/mo. We promise not to raise the price of your subscription while it continues. If you had an Invio account before 1 September 2026, you keep the original prices (Pro NZ$5, Growth NZ$29) for as long as you have the account, including if you cancel and come back. The one exception is an introductory offer, which shows the price that follows it when you sign up (for example, NZ$5 a month for your first 3 months, then NZ$19).
Built for NZ from day one
GST-ready invoices, IRD-aligned records, NZ bank detail fields, and Xero/MYOB export. Not a generic tool retrofitted for New Zealand.
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.
