Question 1

What is an estimate and how is it different from an invoice?

Accepted Answer

An estimate is a document that outlines the projected cost of work before it begins. It is not a request for payment — it gives clients a cost preview so they can approve the project. An invoice, by contrast, is issued after work is completed and requests payment.

Question 2

Is this estimate generator really free?

Accepted Answer

Yes, completely free. You can describe your work in plain English, let AI generate a professional estimate, edit any details, and download a PDF — all without creating an account or entering a credit card.

Question 3

Can I customize the estimate before downloading?

Accepted Answer

Absolutely. After AI generates the estimate, you can edit every field: client name, line items, quantities, rates, dates, payment terms, and notes. You can also choose from multiple professional templates.

Question 4

Can I convert an estimate to an invoice later?

Accepted Answer

Yes. With a free InvoiceAgent account, you can save your estimates and convert them to invoices with one click once the client approves the work.

Question 5

What file format is the estimate downloaded in?

Accepted Answer

Estimates are downloaded as professional PDF files, ready to send to clients by email or print.
