Quotes and estimates: a dated, sourced directory (2027 update)

A quote and an estimate are different documents doing different jobs, and using one word for the other is the most expensive habit in small business paperwork.

A quote is an offer: this work, this price; accepting it means you pay that. An estimate is a forecast: based on what I know now, expect about this, and here is what would move it.

The first puts the risk of being wrong on you, while the second leaves it with the customer. Everything below follows from that point.

A dated directory of providers, tools, rules and typical ranges, covering the FTC, Uniform Commercial Code, AIA, SCORE, HubSpot, PandaDoc, QuickBooks and FreshBooks, appears at the end of this guide.

The directory includes FTC Advertising and Marketing Basics (accessed 2027 update), requiring truthful, substantiated claims; Uniform Commercial Code § 2-201 (accessed 2027 update), requiring a writing for goods of $500 or more; AIA G701-2017 change orders; SCORE, HubSpot, PandaDoc, QuickBooks and FreshBooks templates; typical quote validity of 30 to 90 days; and typical deposits of 10% to 50%.

What to take away

Choosing between them

Whether a document is a binding offer depends on its wording, what the customer does next, and the law where you operate. State plainly on the page which one you intend, not the heading.

The Federal Trade Commission's Advertising and Marketing Basics covers claims made to customers. The wider page the Federal Trade Commission publishes for small businesses is a starting point for the obligations that attach to a document you send a customer.

Where you genuinely cannot tell yet, an estimate with a tight, well drawn scope is more honest and usually more persuasive than a quote padded with contingency you cannot explain.

QUOTATION
[Your entity name, address, contact]
Quotation number: [unique reference]
Date issued: [date]        Valid until: [date]

For: [customer entity name exactly as it will appear on the
invoice, and the site or delivery address if different]

Scope of work
1. [Item, described by what will exist when it is done,
   not by the activity]
2. [Item]
3. [Item]

Not included
- [The adjacent thing the customer will assume is included]
- [Anything conditional on access, permits, or third parties]
- [Anything you have priced separately below]

Price
[Line item]                              [amount]
[Line item]                              [amount]
Total                                    [amount]
[State clearly whether taxes are included in or added to
these figures, and which taxes. If you are not sure how
they apply to this transaction, ask an accountant before
issuing, not afterwards.]

Assumptions this price depends on
- [Access, timing, information, decisions, conditions]

Payment terms
[When payment is due, in what installments, and by what
method. If a deposit is required, say what it secures.]

Changes
Anything outside the scope above will be quoted separately
and started only on your written approval.

Acceptance
To accept, reply in writing quoting [quotation number]
before [expiry date].

The anatomy of an estimate

Same skeleton, three changes, and they are the changes that keep it an estimate.

ESTIMATE (not a fixed price)
[header block as above]

Basis of this estimate
This is a forecast based on [what you have seen or been
told] as at [date]. It is not a fixed price offer.

Expected cost
[Item]                       [range, or figure]
[Item]                       [range, or figure]
Expected total               [range]

What would move it
- [Factor]: [which direction, and roughly how much]
- [Factor]: [which direction, and roughly how much]

Allowances
[Any element priced provisionally, what the allowance
covers, and that it will be reconciled to actual cost.]

How you will be told
If the work looks like exceeding [threshold or percentage],
we will stop and tell you before continuing.

That last block is the part people leave out and the part customers actually want. A number that can move is tolerable if the customer knows when they will hear about it. A number that moves silently and appears on the final invoice is how a good job ends in a dispute.

Writing the scope so it holds

The scope section fails in a predictable way: it describes activity rather than result, and activity has no edge.

The fix is easier to show than to describe. Here is one line from a quotation, written both ways.

The weak line names an activity, so the customer supplies the edges for themselves. The rewritten line names the result and the boundary, so both sides can check it at handover.

Exclusions are the load-bearing section

Customers do not read exclusions as hostility. They read a missing exclusion as an inclusion, which is a much worse outcome for you.

Write them as neutral facts rather than warnings. A short list under a plain heading reads as competence. Buried caveats in small print read as a trap and get argued about later.

Expiry, and why it is not a sales tactic

Every quote should say when it stops being available. This is not pressure selling, it is the only honest way to price when your own costs are quoted to you on terms.

Pick the shorter of two periods: how long your suppliers hold their prices for you, and how long the customer plausibly needs to decide. If a customer comes back after expiry, requote rather than honoring it out of politeness. Honoring an expired quote once teaches the next customer that the date is decorative.

Changes, and the sentence that prevents most arguments

Extra work agreed verbally on site and invoiced later is the single most common cause of a payment dispute. The fix is a mechanism that both sides agreed to in advance.

The same pairing of a document and its follow-up appears in GOV.UK's page on invoicing and taking payment from customers. That page treats what you agreed and what you later bill as one chain rather than two events. Say in the quote that anything outside the scope will be quoted separately and started only on written approval.

Then do it, including for small items: the exception you make for a small item is the precedent quoted back at you for a large one.

A one line message confirming the change and its price is enough, and it is why the business letters overview treats the written record as the point of the exercise rather than a formality.
