What an estimate is and how it differs from a quote
An estimate tells a customer what you expect a job to cost. A quote is a firmer offer. Queensland government small-business guidance puts it plainly: unlike quotes, estimates are not legally binding, and an estimate usually carries a line saying the price is subject to change.
That difference is why this form is titled "Estimate" and prints a notice that the final price may change. If you need to commit to a fixed price, use a quote instead.
What to put on a job estimate
We found no official page that sets required contents for an ordinary estimate. FTC consumer guidance says a written estimate should include a description of the work, the materials, a completion date and the price. A good estimate also shows how the total is built, so the customer can see where the money goes.
- Estimate number and date, so you can refer back to it later.
- Your business name, address and contact details.
- The customer's name and address.
- A plain description of the work.
- Labor and materials as separate lines.
- Whether labor is a flat rate, hourly, or both.
- The estimated total, with tax shown if it applies.
- A valid-until date, because material costs can rise quickly.
How to use the free estimate template
Work through the editor above from top to bottom.
- Add the estimate number, the estimate date and the valid-until date.
- Fill in your business details and the customer's details.
- Describe the work and, if useful, pick flat rate, hourly rate, or both.
- Add each line with a description, quantity and rate. The editor works out each estimated amount.
- Add tax or a discount if they apply. The estimated total updates on its own.
- Add an estimated completion date or a fee for preparing the estimate only if you need them. The fee is shown as its own line and is not added into the estimated total.
- Blank lines for the customer's name, signature, and date print at the bottom of the PDF, for when you want written approval.
- Check the preview, then download the PDF.
When the final bill can go above the estimate
Since an estimate is not a fixed price, the final bill can differ. The rules on how far it can go depend on the state and the type of work.
Some states have written-estimate laws for vehicle repair. California requires its automotive repair dealers to get the customer's authorization before doing additional repairs beyond the original estimate, using a revised work order that describes the added parts and labor. Florida's statute on motor vehicle repair requires "a written repair estimate" in some cases. Its notice-of-charges section makes it unlawful to charge more than the written estimate, with a "whichever is greater" allowance, unless the shop "has obtained authorization to exceed the written estimate."
For other trades, check your state's rules for your trade. A good habit that works everywhere: if the job grows, tell the customer in writing before you do the extra work, and record the new amount.
Turning an accepted estimate into an invoice
Once the customer agrees and the work is done, the estimate becomes the starting point for your bill. Open the Invoice tool, carry over the customer details and line items, and change any amounts to the real figures. The valid-until date is dropped because an invoice has a due date instead. Keep the estimate number in your notes so both documents are easy to match.
Which format to use: PDF, Word, Excel or Google Docs?
A PDF keeps the layout fixed, so the customer sees the same page you sent, and it is easy to email or print. Word, Excel and Google Docs or Sheets let the recipient edit the file, which is handy for drafts but risky for a document with prices. If you build your own in a spreadsheet, you also have to write the formulas and check them. Filling in the editor above and downloading a PDF avoids both problems.

Questions
What is the difference between an estimate and a quote?
An estimate is a rough idea of the cost and is usually not legally binding. A quote is generally a confirmed price you agree to hold. Because of this, an estimate carries a notice that the price is subject to change.
How do I write an estimate for a job?
Name your business and the customer, describe the work, list labor and materials as line items, show the estimated total, and add a valid-until date. Then state clearly that the price may change.
Is an estimate legally binding?
Government guidance describes estimates as not legally binding, unlike quotes. Some states do have written-estimate rules for certain trades, such as vehicle repair, so check the rules where you work.
Can the final price be higher than the estimate?
Often yes, but not always freely. Some states limit how far a bill can go over a written estimate, or require the customer to approve extra work first. These rules differ by state and trade.
How long is an estimate valid?
No official page we read sets a length. Set a valid-until date that reflects how fast your material costs can change, and leave it off only if you are comfortable honoring the prices indefinitely.
Can I make an estimate template in Word, Excel or Google Docs?
Yes, but you must set up the layout and any math yourself. The editor here handles the line items, tax and totals for you and exports a PDF, so there is nothing to build.
