What is an estimate?

An estimate is an approximate price for a job, given before the work starts. Contractors, interior designers, repair shops and service businesses send estimates so the customer knows roughly what it will cost.

Unlike a quotation, an estimate can change: the final bill may be higher or lower once the actual materials and time are known.

Estimate format

An estimate shows your business details, an estimate number and date, the customer's name, each item of work or material with quantity, rate and GST, the estimated total, how long the estimate is valid, and any conditions, such as how much the final bill may vary.

An estimate isn't a tax invoice. When the job is done, issue a GST invoice for the actual amount.

Rules that apply

An estimate isn't a tax invoice

GST is charged on the tax invoice you issue when you supply. Issue it with the details Rule 46 requires once the job is done.

A customer in your own state is charged CGST and SGST; a customer in another state is charged IGST.

Good to know

What is the difference between an estimate and a quotation?

An estimate is an approximate price that can change; a quotation is a fixed price the seller commits to for a period.

Is an estimate legally binding?

Usually not: an estimate is a best guess. Say in the terms how much the final bill may vary.

Should I add GST to an estimate?

Yes, if you're GST-registered. Showing GST gives the customer the full expected cost.

How long should an estimate be valid?

Commonly 15 to 30 days, since material prices change. Set it in the valid-until field.

Can I turn an estimate into an invoice?

Yes. When the job is done, make a GST invoice with the actual quantities and rates.

Is my data stored anywhere?

No. The estimate is made in your browser and its details never leave your device.
