They get used interchangeably, but a quote and an invoice do very different jobs — and mixing them up is how disputes start.
Different documents, different jobs. Mixing them up is how price disputes and late payments start. Here's what each one does in New Zealand.
A quote is what you send before doing the work — your price for the scope you've described. A quote is a firm offer: once the client accepts it, that's the price unless the work itself changes.
An estimate is an educated ballpark; a quote is a fixed price. Use an estimate for early enquiries and jobs with unknowns, and a quote once the scope is clear. Always label the document so the client knows which one they're looking at.
The invoice is what gets you paid once the work's done. In New Zealand it needs your NZBN, GST shown separately (15%), an invoice number, and a clear total in NZD.
Quote first to win the job, then invoice the moment it's finished. UteQuote produces either one by voice in seconds, so there's no reason to let paperwork slow you down.
A quote, once accepted, is generally binding for the scope described. An estimate is only an approximation and is not. Label the document clearly to avoid confusion.
A GST invoice includes the specific fields IRD requires — like your NZBN and GST shown separately. If you're GST-registered, that's what you issue.
UteQuote turns a quick voice note into a IRD-compliant quote or invoice in seconds.
