Frequently asked questions

What is the difference between an estimate and an invoice?

An estimate proposes prices before the work; an invoice requests payment after (or during) the work. Send an estimate, get approval, then convert the same details into an invoice — BillingOtter does that conversion in one click.

Is this estimate maker free?

Yes — free, no signup, generated entirely in your browser and downloaded as a professional PDF. Free downloads carry a small BillingOtter line in the footer; an BillingOtter plan removes it.

How long should an estimate be valid?

15–30 days is typical. Prices, availability and material costs change — a validity date protects you from being held to old numbers.
