Intent boundary: This checklist reviews the completeness and clarity of a service estimate. It does not calculate a price, create binding terms, determine local requirements, or replace legal, tax, licensing, safety, insurance, or trade-specific advice.
First decision
Name the document honestly.
Estimate, quote, bid, proposal, and work order may carry different expectations or legal effects depending on the market, wording, and circumstances. Use the term that accurately describes what you are offering, then use it consistently.
Official consumer guidance in Western Australia and the Northern Territory distinguishes quotes from estimates in those jurisdictions. That is a warning against assuming the words are interchangeable, not a universal definition for every reader.
The 12-point checklist
Make each commercial fact easy to find.
Use the question on each card as the final test. The answer should be clear from the document itself, not only from your memory of the conversation.
Label the document and its purpose
State whether this is an estimate, quote, proposal, or another commercial record. Use the term consistently and make clear whether the amount is approximate, fixed, or conditional.
CHECKCould the customer explain what kind of document they received?Identify both parties
Include the business name, appropriate contact details, and the customer or organization receiving the document. Use only the personal information needed for the transaction.
CHECKIs it clear who prepared the document and who it is for?Pin down the work location
Record the service address, unit, room, asset, equipment, or other verified detail that separates this job from another one.
CHECKCould a worker find the correct place and identify the correct job?Add a reference, version, and issue date
Give the document a unique reference and visible issue date. When facts change, issue a new version instead of silently overwriting the customer's copy.
CHECKCan both parties identify the exact version being discussed?Restate the requested outcome
Describe the problem the customer asked you to address or the result they expect. Do not turn an unverified symptom into a confirmed diagnosis.
CHECKDoes the summary match the conversation, inspection, photos, and notes?Define the included scope
List the work, quantities, service areas, equipment, materials, visits, disposal, testing, cleanup, or documentation included where relevant.
CHECKCould someone who missed the conversation understand what is being priced?Make exclusions visible
State foreseeable items the customer might reasonably assume are included but are not, such as concealed damage, decoration, permits, premium materials, or unrelated repairs.
CHECKAre the most likely misunderstandings addressed before the price?Record assumptions and unknowns
Identify facts the estimate relies on, such as access, measurements, customer information, equipment condition, material availability, or further inspection.
CHECKIf an assumption changes, is it clear that scope, price, or timing needs review?Show how the total is constructed
Present the relevant labor, materials, quantities, travel, disposal, permits, fees, options, discounts, tax treatment, subtotal, and total for this job and market.
CHECKDo the figures add up, use the correct currency, and match the stated scope?Treat timing as an operational fact
Separate estimated duration from a confirmed booking. State verified dependencies involving acceptance, deposit, access, permits, parts, weather, subcontractors, or availability.
CHECKHave you avoided promising an unconfirmed start or completion date?Define validity and revision control
State how long the document remains current when appropriate. Explain that changed scope, pricing, site conditions, or customer requests require review before extra work proceeds.
CHECKCan an outdated document be clearly replaced by a revised version?State acceptance, payment, and the next step
Explain the approved acceptance method, any deposit or payment timing, and what happens next. Do not treat a question or casual reply as authorization without a valid process.
CHECKCan the customer ask, revise, decline, or proceed without guessing?Weak versus clearer
Replace shorthand with an auditable statement.
These examples improve clarity only. They are not universal contract clauses and still need review for the job, trade, customer, and market.
Fix the leaking sink.
Replace the accessible basin trap identified during the visit and test the new connection for visible leaks. Concealed pipework, wall opening, cabinet repair, and unrelated fixtures are excluded unless added in writing.
Any extra work will cost more.
If inspection reveals concealed damage or work outside the listed scope, the affected work will pause while the additional scope, price, and timing are reviewed with the customer.
We can start next week.
Current target start window: {date range}. This remains subject to written acceptance, required access, and material availability. The booking is not final until confirmed separately.
Total: {amount}.
The document shows the included items, subtotal, applicable tax or fees, and total of {amount}. Optional or excluded work is not included in that total.
Let me know.
Review the scope and total, then use the stated acceptance method or reply with a question or requested change. A request for clarification is not treated as approval.
Stop and review
Do not send while a material fact is unresolved.
The checklist is not a permission slip. Pause when the document and the real job no longer match.
- 01
The diagnosis, work location, customer, or decision-maker is unclear.
- 02
A safety, licensing, permit, tax, warranty, or insurance question is unresolved.
- 03
The total has not been checked against the current scope.
- 04
Materials, subcontractors, access, or availability make the timing uncertain.
- 05
The customer requested a change that is missing from the document.
- 06
An earlier version remains attached, linked, or described as current.
- 07
You cannot explain what is included, excluded, and assumed.
- 08
You are relying on copied terms that have not been reviewed for your market.
Sources and scope
Two official examples, used within their limits.
The cited government documents illustrate why written scope, document type, cost detail, validity, acceptance, and changes deserve careful treatment in their respective Australian jurisdictions. They do not define rules worldwide.
Make the estimate clear first
Then turn verified facts into a customer-ready summary.
