Estimate vs. quote: what's the difference?
An estimate is an educated approximation of cost; the final invoice may differ if the scope changes. A quote is a fixed price offer that is binding once accepted for the stated period. Contractors and service businesses usually send estimates for work whose scope may evolve, and quotes for well-defined jobs.
Tips for estimates that win jobs
Break the work into understandable line items, state what is excluded, set an expiry date and explain how changes will be priced. A short note thanking the client and describing next steps makes it easy for them to say yes.
Frequently asked questions
Can I convert an estimate into an invoice?
Yes. Use “Convert this estimate to invoice” — all customer details and line items carry over to a new invoice.
How long should an estimate be valid?
Commonly 15 to 30 days. Shorter validity protects you when material prices change quickly.
Can clients sign the estimate?
Each estimate includes an optional client acceptance line for a signature and date.
