The Estimate Checklist Before You Send It

Why this matters

An estimate is a document you can be held to. Send one with a missing line, fuzzy scope, or a math error and you have handed the customer either a reason to say no or a wedge to hold you to a number that loses you money. Most bad estimates are not priced wrong; they are sent wrong: an exclusion nobody wrote down, a total that does not add up, the wrong contact name, no expiration. This card is the pass you run before you hit send, so what leaves your hands is complete, correct, and defensible.

Phase 1: The scope is complete and unambiguous

The single most common failure is scope the customer reads one way and you meant another.

• Every task you intend to do is listed as its own line, not bundled into a vague "and related work."
• The scope matches what you actually saw or measured, not a template you forgot to edit.
• Quantities, sizes, and counts are the real ones for this job, not carried over from the last quote.
• Anything conditional is labeled: "if the panel is accessible," "assumes existing lines are usable."
• What is NOT included is stated in writing. Silent exclusions are where scope creep starts. See related: Scope Creep Starts at the Estimate.

Phase 2: The money is right

Check the arithmetic and the structure before the customer does.

• The line items sum to the subtotal, and the totals actually add up. Re-add them, do not trust the first pass.
• Tax is applied correctly for the work and the customer's status, or its absence is intentional.
• Labor, materials, and any fees are all accounted for, with nothing left off that the job needs.
• If you are offering options or good-better-best, each tier is priced consistently and clearly separated.
• The number reflects the real cost of doing the work right, not a figure shaved to win it that you will regret on site.

Phase 3: The terms that protect you

An estimate without terms is a promise with no boundaries.

• An expiration date is on it, so a quote from months ago cannot be enforced at today's material reality.
• Deposit or payment terms are stated: what is due when, and what triggers the balance.
• Warranty on the work and on parts is spelled out, not assumed.
• The document says clearly that it is an estimate, and how change orders or surprises will be handled.
• Any permit, inspection, or third-party cost the customer is responsible for is named.

Phase 4: The details that make it land

Small errors here cost you credibility before the customer reads a single price.

• The customer's name, company, and service address are correct and spelled right.
• Your license number, contact information, and company details are present and current.
• The date is today's, and any reference or job number is correct.
• The document is clean and readable: no leftover placeholder text, no broken formatting, no wrong logo.
• There is a clear next step: how to accept, how to reach you with questions, and by when.

The read-it-as-the-customer test

Before sending, read the whole thing once as if you were the customer receiving it cold, with no memory of the site visit. If a line would make you ask "what does that mean" or "is that included," fix it now. Every question you answer in the document is a phone call you do not have to take and a delay you do not add to the close.
