Create an estimate before work starts

Use an estimate before work begins when a client needs projected cost, scope, and validity terms before approving a job. It is useful for service calls, design work, repair jobs, consulting projects, and any quote-like document where the final invoice may change after approval.

Turning an estimate into an invoice

After the client approves the estimate, copy the scope, line items, and pricing into an invoice, then set payment terms and due date for the actual payment request.

Make the scope easy to approve

Keep estimate line items specific enough for the client to understand what is included. Add validity terms, optional items, deposit expectations, and notes about what may change the final price.

Avoid unclear quote language

Do not make legal or tax promises in the document. Use practical wording that explains projected costs, assumptions, and next steps, and review any binding quote requirements with a qualified professional when needed.

Estimate example for a small project

A useful estimate explains the expected scope and price before work begins. This example separates discovery, design, and implementation so the client can see what contributes to the projected total.

Estimated itemQuantityRateAmount
Discovery workshop2 hours$125$250
Homepage design1 project$1,200$1,200
CMS implementation1 project$1,800$1,800
Estimated subtotal$3,250

Add a valid-until date, assumptions, optional work, deposit expectations, and a note explaining what could change the final price. Replace every sample value with the scope agreed with your client.

Estimate

Shows projected scope and cost. The final price may change if assumptions or work change.

Quote

May communicate a firmer offered price, depending on your wording, agreement, and local rules.

Invoice

Requests payment for completed work, a deposit, or an approved milestone.

From accepted estimate to invoice

Save the accepted scope, record additions before billing them, and carry the same descriptions into the invoice. Change the document number from an estimate prefix to an invoice prefix, replace the validity date with payment terms and a due date, then run the invoice checker before sending.

FAQ

What is the difference between an estimate and an invoice?

An estimate quotes expected work and pricing before the job starts. An invoice requests payment after work is done or at a milestone.

Can I turn an estimate into an invoice later?

You can reuse the same line items and client details, then switch to the invoice generator when you are ready to bill.

Is the estimate PDF free to download?

Yes. No signup is required.

Is an estimate the same as a quote?

Both describe proposed work and pricing, but a quote may communicate a firmer offered price depending on the wording, agreement, and local rules.

Can a client sign the estimate in this tool?

The tool creates a PDF estimate but does not collect electronic signatures or approvals. Send the PDF through the approval process you use with your client.
