FAQ
Frequently Asked Questions
Is this invoice generator really free?
Yes, completely free. You can create, fill in, and download as many invoices as you like with no email gate, no watermark, and no credit card.
Do I need to sign up to use it?
No. The generator works entirely in your browser - no account needed. If you want to save clients, send invoices by email, and track payments, you can sign up to Invio for free.
Does it handle GST correctly?
Yes. The tool supports two modes: prices entered excluding GST (adds 15% on top) and prices entered including GST (back-calculates the 3/23 GST component). If you are not GST registered, toggle that off and no GST will appear on the invoice.
Can I download the invoice as a PDF?
Yes. Click "Download PDF" and a real PDF file saves directly to your device - no print dialog, no new window. The file is named Invoice-INV-001.pdf (using your invoice number) and is formatted for A4.
When do I need to register for GST in NZ?
You must register for GST once your turnover exceeds $60,000 in any 12-month period. Below that threshold, registration is optional. Once registered, you charge 15% GST on taxable supplies and must issue tax invoices that include your GST number.
