What is an estimate?
An estimate is a written approximation of what a job will cost, given before the work starts. It's not a bill — it's a basis for agreement, usually with line items, assumptions, and a valid-until date. Clients use it to approve budgets; you use it to set expectations.
In practice
A painter estimates a two-bedroom repaint: labor 24 hours x $55 = $1,320, paint 8 gallons x $48 = $384, supplies $120 — estimated total $1,824, valid 30 days. When the client approves, the painter converts the estimate into an invoice with the same line items after the job is done.

Is an estimate legally binding?
Usually not — it's an approximation, not a contract. But a signed estimate with clear scope can become binding if both sides treat it as the agreement, so list your assumptions.
What's the difference between an estimate and a quote?
An estimate is an educated guess that may move; a quote is a firm fixed price for a defined scope. Quotes commit you; estimates give you room.
How long should an estimate be valid?
30 days is standard. Material prices and your availability change, so always put an expiry date on it.
