Frequently asked questions
What is the difference between an estimate and a quote?
Both outline costs before work starts. An estimate is usually a ballpark figure that can change; a quote is a fixed price the client can hold you to. Invoala's estimate mode shows an estimated total and a validity date.
What should a job estimate include?
Your business details, the client's details, a description of the work as line items, quantities and rates, an estimated total, and how long the estimate is valid for.
Can I turn an estimate into an invoice?
Yes. When the client approves, click "Convert to invoice" — the same line items carry over and a due date is set automatically. No retyping.
Are estimates legally binding?
Estimates are generally not binding unless you state otherwise. A quote is treated as a firm offer. Always note a validity period so old prices don't come back to haunt you.
Is the estimate generator free?
Yes — no sign-up, no watermark, no limits. Download as many estimate PDFs as you need.
