What to put on a job estimate

  • Your business and client details so the estimate is clearly addressed and traceable.
  • An estimate number and a "valid until" date — 30 days is standard and protects you from price swings.
  • Itemized labor and materials with quantities and rates so the client sees exactly what they're paying for.
  • Subtotal, tax, and estimated total — clear numbers build trust and close jobs.
  • Terms noting it's an estimate and prices may change after the expiration date.

Frequently asked questions

What's the difference between an estimate and a quote?
An estimate is your best approximation of what a job will cost and can change as the work is scoped. A quote is a fixed price you commit to. This tool works for both — set a 'valid until' date and clear terms so the client knows which one they're getting.
Is this estimate generator free?
Yes — completely free, no signup, no watermark, and no email required. Fill it in, add your line items, and download a clean PDF estimate from your browser.
How do I turn an estimate into an invoice?
Once the client approves the estimate, you re-issue the same line items as an invoice with a due date. You can use our free invoice generator for that — or let JobStack convert an approved estimate into an invoice with one tap.
What should a job estimate include?
A good estimate has your business details, the client's details, an estimate number, the date and a 'valid until' date, an itemized breakdown of labor and materials with quantities and rates, the subtotal, any tax, the estimated total, and terms noting that prices may change after the expiration date.
How long should an estimate be valid?
30 days is standard for the trades. It gives the client time to decide while protecting you from material price swings. Always state the expiration date on the estimate so there's no dispute later.
