AvoWhat Is a Quote? Definition, How It Differs From an Estimate, and What It Must Contain
A quote (quotation) is a fixed-price offer for a defined scope of work or goods, valid for a stated period: once the buyer accepts it, the price is set.
Definition
A quote, or quotation, is a document in which a seller offers to supply specific goods or do specific work for a fixed price, valid until a stated date. When the buyer accepts, the quote becomes the agreed price, and the seller cannot raise it unless the scope changes. “Quote” is the common American term; “quotation” means the same thing and is more usual in formal and international business.
The other everyday meaning of “quote”, repeating someone's words, has nothing to do with this page; in business, to quote a job is to put a price on it.
Quote vs estimate vs bid vs proposal
| Quote | Estimate | Bid | Proposal | |
|---|---|---|---|---|
| Price | Fixed for the stated scope | Approximate; may change | Fixed; competitive | Fixed, often with options |
| Binding when accepted | Yes | No (terms yes, price no) | Yes, per bid rules | Yes, for the option chosen |
| Typical validity | 14–30 days | 30 days | Set by the bid | 30 days |
| Use when | Scope is clear | Scope or conditions uncertain | Formal competitive work | Client needs the approach, not just the price |
What a quote contains
- Your business details and the client's.
- Quote number, date, and the valid-until date.
- Scope: what is included, in plain words, and what is excluded.
- Priced lines: description, quantity, unit price, amount; materials and labor separate.
- Subtotal, tax if applicable, total.
- Deposit and payment terms that will apply once accepted.
- Assumptions and conditions: access, materials supplied by the client, change-order process.
- An acceptance line: name, signature, date.
When a quote is binding
A quote is an offer. It becomes a contract when the client accepts it within the validity period, by signing, by replying in writing, or by paying the deposit. From then on the price holds for the scope described. Anything outside the scope is a change order with its own price. That is why the exclusions on a quote matter as much as the inclusions: they define what the fixed price does not cover.
If the client accepts after the valid-until date, the seller may re-quote. If the seller makes a clear arithmetic error, most courts allow correction before acceptance, but not after the client has relied on it.
How a quote becomes an invoice
- Keep the line items identical. The client approved specific lines; the invoice should repeat them, plus change orders on their own numbered lines.
- Credit the deposit as a negative line so the invoice total is the balance due.
- Reference the quote number on the invoice (“per quote Q-2026-07, accepted Mar 2”).
- If you quote often, use a template or app that converts a quote into an invoice without retyping.
Quote examples by situation
| Situation | What the quote looks like |
|---|---|
| Trade job (plumbing, painting) | Scope paragraph, lines per task and per material, exclusions, 30-day validity, 30% deposit |
| Product order (wholesale) | Items with SKU, quantity, unit price, delivery terms, validity tied to supplier pricing |
| Service package (photography, cleaning) | Package name, what is included, add-ons priced separately, date held on deposit |
| Freelance project | Deliverables, revision rounds, timeline, milestone payments, usage rights |

Questions
What is a quote in business?
A fixed-price offer to supply goods or services as described, valid until a stated date. Accepted in time, it sets the price. It differs from an estimate, which is an approximation that can change.
Is a quote legally binding?
Once accepted within its validity period, generally yes, for the scope it describes. Before acceptance it is an offer the seller can withdraw. The exclusions and the valid-until date define its limits.
What is the difference between a quote and an invoice?
A quote comes before the work and states the price offered; an invoice comes after and requests payment for what was done. A good invoice repeats the quote's lines so the client can see they match.
Can a quote be changed after it is accepted?
Only by agreement, usually through a change order for work outside the original scope. The accepted price for the original scope stays fixed.
How long is a quote valid?
Whatever the quote says: 14–30 days is standard. Shorter when material prices move fast. Without a date, courts may treat it as valid for a reasonable time, which is an argument you do not want.
Quote or quotation: is there a difference?
No. “Quotation” is the formal word and the usual one outside the US; “quote” is standard American business usage. Either works as the document title.
