How to write a project estimate in 2026
A good estimate protects you from scope creep and protects the client from surprises. List each part of the project as its own line with a clear description and price, note that the figures are estimates that may change if scope changes, and add an expiry date so the quote isn't open forever. Once the client approves, you keep the same line items and turn it into your first invoice — no re-typing. Build yours above and save it as a PDF.
Estimate by billing model
Hourly
Charge by the hour — add rate/hr and hours
Fixed Price
One price per line item — simple and clear
Retainer
Monthly or periodic retainer — add period and scope
Milestone
Project milestones — name, amount, due date each
Estimate pro tips for freelancers
- Always put an expiry date — open-ended quotes lose urgency.
- Include a note: "Prices may change if the scope changes."
- Number your estimates (EST-0001) separately from invoices.
- For big projects, break the estimate into phases with milestones.
- Add tax even on estimates — the client should see the full anticipated cost.
- Save your estimates as PDFs so you have a record of what you quoted.
Frequently asked questions
What's the difference between an estimate and an invoice?
An estimate (or quote) is what you send before the work starts — it shows the client the expected cost so they can approve it. An invoice is what you request payment with once the work is done. The structure is nearly identical, so you can build your estimate here, get it approved, then reuse the line items as your invoice.
Is this estimate generator free in 2026?
Yes — completely free with no sign-up, no account and no watermark. Build your estimate, save it as a PDF, and share it with your client. We monetize through ads, not your data.
Can I turn an approved estimate into an invoice?
Yes. Because the line items are saved in your browser, you can open the generator again, edit the same details, change the title in your notes from 'Estimate' to 'Invoice', and save the final version once the client approves. No re-typing required.
What should an estimate include?
A professional estimate needs: a unique reference number, the date, an expiry date (typically 30 days), your business details, the client's details, a clear list of each deliverable or service with its estimated cost, any tax, the total, and a note that figures are estimates subject to change if scope changes. Add your payment terms so the client knows what to expect.
What billing model should I use for estimates?
Match the billing model to the project type. Use fixed-price estimates for defined-scope projects (logos, websites), hourly estimates for open-ended work (consulting, development), milestone-based estimates for phased projects, and retainer estimates for ongoing monthly work. The generator supports all four models.
How long should an estimate be valid?
Most freelancers set a 30-day expiry on estimates. This protects you if your costs or availability change, and it gives the client a deadline to decide. Put the expiry date prominently on the estimate. For urgent projects, 7-14 days is reasonable.
Can I add tax to an estimate?
Yes. If you know the tax rate that will apply, include it on the estimate so the client sees the full expected cost. InvoicePad supports US sales tax, UK VAT (20%), EU VAT by country, Australia GST (10%), and Canada GST/HST. The estimate should match what the final invoice will show.
