Tip
Estimate accepted? The Inbill app turns saved clients and products into the matching invoice in about two minutes — then tracks the payment against it.
Start free — 5 invoices a monthEstimate, quote, or invoice?
The three documents mark three moments of the same job: an estimate opens the conversation, a quote closes the price, an invoice collects the money. The biggest practical difference is commitment — estimates are flexible, accepted quotes are binding, invoices are due.
| Estimate | Quote | Invoice | |
|---|---|---|---|
| When it goes out | Early, while scope is still moving | Once scope and price are fixed | After the work is delivered |
| What it says | "It will cost roughly this" | "It will cost exactly this, if you accept" | "You now owe this" |
| Commitment | Not binding — an approximation | Binding once the client accepts | A payment obligation with a due date |
| Typical next step | Firm it up into a quote | Client accepts, work starts | Payment lands, receipt goes out |
Questions, answered plainly.
Is this estimate maker really free?
Yes. It creates and downloads a PDF estimate with no sign-up, no watermark, and no card. It runs entirely in your browser — nothing you type is uploaded.
What is the difference between an estimate and a quote?
An estimate is an educated approximation sent while the scope still has unknowns; the final cost may move. A quote is a fixed price for a defined scope — once the client accepts it, you are expected to honor it. Use this tool for either: the "Valid until" date keeps old pricing from haunting you.
Is an estimate legally binding?
Generally no — an estimate is presented as an approximation, not an offer. An accepted quote or a signed contract is what creates the obligation. Rules vary by country, and drifting far beyond an estimate without warning the client invites disputes — flag changes early. (This is general information, not legal advice.)
How do I turn an estimate into an invoice?
When the client says yes, recreate the same line items in the invoice generator — or use the Inbill app, where saved products and clients make the estimate-to-invoice step a two-minute job, with payment tracking after it is sent.
Should my estimate have an expiry date?
Yes. Materials, rates, and your availability change — a "Valid until" date (14–30 days is common) makes that explicit and gives the client a gentle reason to decide.
