Quick answer: an estimate is an approximate price that can change as you learn more about the job. A quote is a fixed price for a defined scope, valid for a set time. A bid is a fixed-price offer made in competition with other contractors. A proposal wraps the price in a fuller plan with approach, timeline and options.
Comparison table
| Estimate | Quote | Bid | Proposal | |
|---|---|---|---|---|
| Price | Approximate | Fixed | Fixed | Fixed or ranged |
| Can change? | Yes, if the job differs | Only if scope changes | Only if specs change | By agreement |
| Typical use | Repairs and jobs with unknowns | Well-defined service work | Tenders and commercial work | Larger or custom projects |
| Detail level | Line items and assumptions | Line items and terms | Matches the buyer’s specs | Price plus plan, timeline and options |
What is an estimate?
An estimate is your best price for the job based on what you can see. It is common when there are unknowns, such as hidden damage behind a wall. A good estimate states its assumptions and how changes will be handled, so the final bill does not surprise anyone.
What is a quote?
A quote commits to a price for a clearly defined scope, usually for a stated period such as 14 or 30 days. If the customer accepts within that time and the scope does not change, the price holds.
What is a bid?
A bid is a fixed-price offer submitted when a customer is formally comparing contractors, often against written specifications. Commercial and public projects use bids; homeowners often call any priced offer a bid.
What is a proposal?
A proposal sells the project as well as pricing it. It typically includes the scope, approach, timeline, options or packages, and terms. Designers, remodelers and landscapers use proposals for larger jobs.
Which one should you send?
- Send an estimate when you cannot fully confirm the scope before starting.
- Send a quote when the scope is clear and you can commit to the price.
- Submit a bid when the customer has asked several contractors to price the same specification.
- Prepare a proposal when the customer needs to understand the plan, not only the price.
Whatever you call it, the customer needs a clear scope, itemized price, terms and a simple way to say yes. SprigDeal supports all four with itemized estimates, a scope description, terms, a valid-until date and online acceptance.
Frequently asked questions
What is the difference between an estimate and a quote?
An estimate is an approximate price based on what you know so far and may change if the job turns out differently. A quote is a fixed price for a clearly defined scope that you agree to honor for a stated period.
Is a bid the same as a quote?
A bid is a fixed-price offer submitted in competition with other contractors, usually in response to a request with set specifications. In everyday use, many people say bid, quote and estimate interchangeably.
What is a proposal?
A proposal is a more complete sales document. It usually contains the price plus the approach, timeline, options and terms, and is common for larger or design-heavy projects.
Do UK and Australian customers use different terms?
Yes. In the United Kingdom and Australia, “quote” or “quotation” is the everyday word for a priced offer, while North American customers more often say “estimate.”
