What is a Job Estimate?

An estimate is your good-faith approximation of what a job will cost, sent before the work begins.

Unlike an invoice, an estimate does not request payment — and unlike a firm quote, it is an approximation: the final bill can move if the scope does. In US trades (contractors, repair shops, landscapers, handymen) the estimate is the standard first document. Done right, it protects both sides:

  • For the client: an itemized picture of labor and materials before committing
  • For you: a documented, dated approximation — with a validity date, so old prices can't be claimed months later
  • For the job: the reference every change order and the final invoice point back to

Once the client approves — ideally in writing — you do the work, record any changes as change orders, and issue a formal invoice for the same items. Need a firm, binding price instead? Use our quotation generator; for the writing craft itself, see how to write a quote.

How to Create a Job Estimate

Six steps to an estimate your client can approve on the spot.

  1. 1
    Enter Your Business Details

    Add your business name, address, and contact information — and upload your logo for a professional look.

  2. 2
    Add the Prospective Client

    Enter the client's company name and address exactly as they should appear on the offer.

  3. 3
    Set the Validity Date

    Choose how long the estimated prices stand (commonly 30 days — shorter when material prices are moving).

  4. 4
    List Labor and Materials

    Separate labor lines (hours × rate) from material lines. Itemized estimates get approved faster and disputed less.

  5. 5
    State the Estimate Terms

    Say plainly that the figure is an estimate, how scope changes are handled (written change orders), and how the client approves.

5 Common Estimate Mistakes

Avoid these errors to win the job and protect your margin when scope moves.

1
No Validity Date

An open-ended estimate can be approved months later at outdated material prices. Always set "Valid Until".

2
Lumped-Together Pricing

"Job — $X" invites disputes. Separate labor from materials and spell out what counts as an extra.

3
No Change-Order Language

Say up front that scope changes are priced in writing before the work happens — that one line prevents the end-of-job fight.

4
Forgetting Taxes

Say clearly whether prices include or exclude tax. Surprises at invoice time damage trust.

5
No Estimate Number

Numbered estimates (EST-2026-001) are easier to reference in change orders, invoices, and bookkeeping.

Estimate FAQ

What is the difference between an estimate, a quote, and a bid?

An estimate is a good-faith approximation of what a job will cost — the final invoice can differ if the scope changes. A quote (quotation) is a firm price offer for a defined scope, usually binding once accepted within its validity window. A bid is a formal offer in a competitive tender, common in construction and government work. This tool produces a clearly labeled estimate; if you need a firm offer, use our quotation generator.

Is an estimate legally binding?

Generally no — an estimate is an approximation, not a fixed price, and the final invoice may differ if the work changes. But the label alone does not decide it: if the document reads like a firm offer and the client accepts it, it can be treated as one, and some jurisdictions expect the final bill to stay reasonably close to a written estimate. Say clearly on the document that prices are estimates subject to scope, and confirm changes in writing.

What should a job estimate include?

Your business details, the client's details, an estimate number, the issue date, a validity date, itemized labor and materials with quantities and prices, any tax treatment, the estimated total, and a line stating that the figure is an estimate and how changes to scope will be handled.

How do I handle changes after the client approves the estimate?

Put it in writing before doing the extra work: a short change order stating what changed, the price impact, and the client's approval. Change orders referenced back to the estimate number keep the final invoice defensible and avoid the classic end-of-job dispute.

How long should an estimate stay valid?

Common validity periods are 14, 30, or 60 days. Material prices move, so trades often keep estimates shorter. This tool defaults to 30 days, and you can set the validity date to anything you like.

How do I turn an approved estimate into an invoice?

Once the client approves, deliver the work and recreate the same line items in any of our invoice generators, adding a due date and your payment terms. Reference the estimate number on the invoice so both documents tie together in your records.

Is this estimate generator really free?

Yes. No account, no email requirement, and no watermark you have to pay to remove — a small footer credit is on by default and one free checkbox removes it. A fair-use anti-abuse cap of 20 PDFs per device per day applies, far above normal use. Data is encrypted in transit for PDF generation and deleted after processing.
