Estimate generator FAQ

What's the difference between an estimate and a quote?

An estimate is an approximate price that may change as the job is scoped; a quote is usually a fixed price offer. Both are pre-work documents — use whichever your client expects. InvoiceSonic creates both free.

Is an estimate legally binding?

An estimate is generally an approximation, not a binding contract, whereas a fixed quote can be. Make clear on the document whether your pricing is an estimate or a firm quote.

Should an estimate include GST?

If you're registered for GST, show the 10% GST so the client sees the full expected cost. Our generator adds GST automatically when you toggle it on.

Is the estimate generator free?

Yes — create and download professional estimates for free, with no signup or watermark.
