Estimates that win the job
A clear estimate sets expectations and makes you look professional before a dollar changes hands.
“Valid until” built in
Every estimate carries an expiry date, so old prices don't come back to haunt you months later.
Same details as your invoice
Line items, tax, and discounts work exactly like the invoice generator — clients see consistent documents at every step.
One click to invoice
Job accepted? Pro converts the estimate into a numbered invoice instantly, with nothing retyped.
Estimate questions, answered
What is the difference between an estimate and a quote?
In everyday use they overlap: an estimate is an approximation of cost that may change, while a quote is a fixed price offer. QuietBill's estimate document works for both — set a “valid until” date and state your terms. More in our guide to the three documents.
Can I turn an estimate into an invoice?
Yes. With QuietBill Pro, one click converts the estimate into a new invoice with a fresh invoice number and due date — no retyping.
Is the estimate maker free?
Yes — unlimited estimates, free, with no account. Your data stays in your browser and is never uploaded.
How do I send the estimate to a client?
Click “Download PDF”, choose “Save as PDF” in your browser's print dialog, and email the file to your client like any attachment.
Job done? Invoice it.
