A construction estimate should include your business and licence details, the client and job address, a written scope of work, itemised materials and labor, allowances, clear exclusions, taxes, the total price, payment terms and deposit, a validity or expiry date, and a signature block. Anything missing becomes an argument later.
Every disputed job traces back to something that was not written down. Use this as a checklist before you send anything.
The scope is where you win or lose arguments. Write what you will do, in what sequence, and to what standard. Name the materials by grade or model where price depends on it. If demolition, disposal, permits, painting or clean-up are not included, say so in the exclusions instead of leaving it implied.
An allowance is a budget placeholder for something the client will choose later, such as tile or fixtures. An exclusion is work you are not doing at all. Confusing the two is the most common source of change-order fights. Give every allowance a number, a unit and a note that overages will be billed as a change order.
Most residential clients accept a single total or per-section pricing. Detailed cost-plus breakdowns invite line-by-line negotiation. Decide deliberately whether the client sees unit costs, and keep your internal cost view separate from the client-facing document.
WinkScope drafts the scope with AI from a plain-language job description, prices materials from a live vendor price book, applies your markup rules and tax settings, and outputs a branded PDF with allowances, exclusions, payment schedule and e-signature. Approved estimates convert into a project with a schedule and an invoice plan.
That depends on your market. Separating labor makes the bid transparent and easier to compare against competitors, which can hurt you. Many contractors show labor as a phase total rather than an hourly figure.
14 to 30 days is standard. With volatile material pricing, 14 days is safer, and the expiry should be stated on the document.
Generally an estimate is not a contract until it is accepted and signed, and terms vary by jurisdiction. Once signed with a scope, price and payment terms, it usually forms a binding agreement.
