Short answer: A professional GC proposal makes the scope, price, assumptions, schedule, and decision path easy to understand. A polished PDF or e-signature cannot fix a missing scope item or guarantee that the client will choose you. Use a proposal checklist, review it with the buyer, and measure the result by project type rather than repeating industry “close-rate” numbers without a source.
Disclosure: Opsite publishes this guide and offers construction management software with proposal workflows on some plans. The checklist is for evaluating your process and any software you consider; it is not a promise of more signed jobs or legal advice.
What should a construction proposal include?
Use the same structure for every comparable job, then adapt it to the project and the agreement you intend to use. A useful review asks whether a client and your PM would describe the same work after reading it.
- Project and version: identify the client, job address, proposal date, revision, and drawings or scope documents used. If an addendum arrived after pricing, say whether it is included.
- Scope and deliverables: describe the work by phase or trade in terms a client can follow. Tie major selections, materials, or performance requirements to the source document where possible.
- Exclusions and assumptions: name work you did not price, allowances that may change, site conditions you could not verify, and client decisions still open. A vague “by others” note is easy to miss.
- Price and payment: show the price basis, allowances, taxes where applicable, deposit or draw milestones, and what triggers each payment. Confirm that the totals match your internal estimate.
- Timing and responsibilities: state the expected start window, major milestones, client-supplied items, access needs, and dependencies such as permits or long-lead products. Separate a target schedule from a guarantee.
- Changes and acceptance: explain how scope, cost, or time changes will be proposed and approved, who can authorize them, and how the accepted version will be recorded. The AIA's change-order guidance emphasizes documenting scope, cost, and time effects in an agreed change; use the terms and forms appropriate to your contract.
- Proof and next step: include relevant license or insurance information where required, project examples you have permission to show, a contact for questions, the proposal validity period if one applies, and a clear review or acceptance step.
Have someone who did not prepare the estimate read the proposal before it goes out. Ask them to find the drawings used, the key exclusions, the total price, and what the client is being asked to approve. If they cannot, simplify the document. Have qualified counsel review contract terms and local requirements for your business.
Presentation helps only when the underlying bid is clear
A branded web proposal can be easier to navigate on a phone than a dense spreadsheet. An e-signature can make acceptance more convenient. Neither establishes a universal signing-speed improvement. The questions to test are practical: Can the client find the scope and exclusions? Can they ask a question before signing? Can both sides retrieve the exact accepted version later?
Do not imply that a proposal was opened by a specific person just because an email-tracking pixel fired. If your software offers view tracking, treat it as a rough follow-up signal. A straightforward follow-up asks whether the client received the proposal, what is unclear, and when they expect to decide. Respect the communication preference and decision process they gave you.
Make the handoff into the job visible
Before choosing proposal software, run one sample job from estimate to accepted proposal to active project. Ask the vendor to show where the signed scope, allowances, payment milestones, client decisions, and change history appear after acceptance. Check whether your PM must re-enter information and whether later revisions remain traceable. A demo should use the plan you would actually buy.
Opsite lists proposal building, e-signatures, and view tracking; its current plan page places proposal features in Professional and above. Ask to see the exact proposal-to-job handoff, permissions, and record history for your contract. Do not assume every step is automatic or available on Starter.
Measure whether your process improves
Track proposals sent, revisions requested, signed proposals, time to decision, and jobs that later need a scope correction. Group them by job type, lead source, and approximate project size. Compare similar groups over time, while noting price, capacity, and seasonality. An increase in raw signing percentage does not prove that a template or AI tool caused it, and a higher win rate is not useful if the resulting jobs are poorly scoped or unprofitable.
If you want to test AI earlier in the bid, see our GC guide to AI takeoffs, budgets, sub quotes, and proposals. If your main problem is carrying an approved proposal into changes, draws, invoicing, and sub coordination, request an Opsite workflow review with one representative job. We will show where the platform fits and which steps still need your team.
