Free AI Proposal Builder for Contractors: What to Include Before You Send

Fast proposals win trust, but fast cannot mean vague. A homeowner or property manager should be able to read your proposal and understand what you are doing, what is not included, what it costs, and what happens next.

That is where a free AI proposal builder can help. It should not replace your pricing judgment, measurements, site notes, or trade expertise. It should help you turn those details into a cleaner proposal without spending another hour formatting a document after work.

Roxy is built for that job: contractors can generate up to 10 Roxy-branded proposals every 30 days on the Free plan. Pro is $49/mo when you need more room to create proposals.

Start with the job facts

Before you ask any AI tool to draft a proposal, gather the details that only you know from the lead call, walkthrough, or site visit.

At minimum, write down:

• Customer name and project address
• Trade and job type
• Main problem the customer wants solved
• Measurements, counts, or quantities you are using
• Materials, equipment, or finish level
• Labor scope
• Access issues, site conditions, or prep requirements
• Timeline assumptions
• Price, deposit, progress payment, or payment schedule
• What the customer needs to do next

For an HVAC replacement, that may include the current system, tonnage, equipment option, ductwork assumptions, thermostat, permit note, and disposal. For painting, it may include rooms, wall condition, prep, number of coats, paint line, exclusions, and furniture movement. For roofing, it may include tear-off, underlayment, flashing, ventilation, shingle line, cleanup, and warranty terms.

AI can draft the document. It cannot know which assumptions are true unless you provide them.

Use a proposal structure customers can scan

A strong contractor proposal does not need to be fancy. It needs to be complete enough for a customer to approve with confidence.

Use this structure:

1. Project summary

2. Scope of work

3. Materials or equipment

4. Options, if applicable

5. Exclusions and assumptions

6. Timeline

7. Price and payment terms

8. Warranty or workmanship note

9. Customer next step

The scope should be specific. "Paint exterior" is too loose. "Pressure wash exterior siding, scrape loose paint, caulk visible gaps around trim, spot prime bare areas, and apply two coats of exterior acrylic paint to siding and trim" gives the customer a better basis for approval.

The exclusions matter just as much. If drywall repair, hidden rot, electrical changes, permit fees, landscaping repair, or material upgrades are not included, say so clearly. Good exclusions protect the customer from surprise and protect you from doing free work later.

Add options only when they help the sale

Good/Better/Best options are useful when the customer is choosing between real levels of value. They are not useful when they make a simple repair feel complicated.

Use options for:

• HVAC equipment tiers
• Roofing shingle lines or ventilation upgrades
• Painting paint grades or added rooms
• Landscaping phases
• Remodeling fixture packages

Keep each option short. Explain the practical difference, not just the price difference. For example: "Better adds a higher-efficiency system and smart thermostat" is clearer than a long equipment paragraph.

Write the scope like a handoff, not a brochure

The easiest way to test a contractor proposal is to ask whether your crew could use it as a clean handoff. If the answer is no, the customer probably cannot use it as a buying document either.

A strong scope should answer:

• What work is included?
• Where will it happen?
• What materials, equipment, or finish level are assumed?
• What prep is required before the main work starts?
• What cleanup, testing, or close-out work is included?
• What is specifically not included?

For example, "install new flooring" is not enough. A better scope says whether furniture movement is included, whether old flooring is removed, whether subfloor repair is excluded, what material line is being installed, whether transitions are included, and what rooms are covered.

The same pattern applies across trades. HVAC proposals need equipment, duct, electrical, drain, thermostat, permit, and removal assumptions. Painting proposals need areas, prep, coats, paint line, protection, and exclusions. Landscaping proposals need phases, materials, plant warranty terms, access, irrigation, disposal, and customer maintenance expectations.

AI can make wording smoother, but the proposal only gets stronger when the inputs are precise. The goal is not to make a thin scope sound impressive. The goal is to make the real scope easier to understand.

Include exclusions before the customer has to ask

Exclusions are not a sign that you are difficult to work with. They are a sign that you know where jobs go sideways.

Most disputes start in the gap between what the contractor meant and what the customer assumed. If the proposal says "paint main floor," the customer may assume ceilings, closets, trim, doors, moving furniture, nail-pop repair, and touch-ups after other trades. If the proposal says "replace HVAC system," the customer may assume duct replacement, electrical panel upgrades, drywall repair, and permit fees.

Good exclusions protect both sides.

Use language like:

• "Drywall repair beyond minor nail holes is not included unless listed as an option."
• "Electrical upgrades are not included unless specified in the scope."
• "Hidden rot, subfloor damage, or structural repairs discovered after removal will be reviewed before additional work proceeds."
• "Permit fees are included only where stated."

This makes the proposal feel more professional, not less. Customers may not love every exclusion, but they usually respect clarity more than surprises.

Make the price easier to understand

A proposal should not hide the price. It should give the price context.

For simple work, one total may be enough. For larger work, break the proposal into useful sections:

• Base scope
• Options or upgrades
• Allowances
• Deposit
• Remaining balance
• Expiration date

Avoid line-iteming yourself into a negotiation over every small material. The point is not to reveal your internal margin. The point is to help the customer understand what the number includes.

If a price depends on an assumption, say it directly. "This price assumes existing wiring is adequate for the selected fixture locations" is better than absorbing a surprise later. "This price includes two coats on listed walls and excludes ceilings" prevents an awkward conversation after the customer has already approved.

The more clearly the proposal explains the number, the less the sale depends on you defending it in a phone call.

Add a next step that matches the job stage

Many contractor proposals end weakly. They explain the work, show the price, then trail off with "let us know."

That creates friction. The customer has to figure out how to move forward, what approval means, whether a deposit is due, and when scheduling starts.

End with one clear next step:

• Approve the proposal and choose an option.
• Reply with requested changes.
• Confirm the installation window.
• Submit the deposit if required.
• Request a trade template or feature if the current workflow is missing something.

For larger jobs, explain what happens after approval:

"After approval, we confirm material availability, reserve the work window, and send a short pre-job checklist covering access, site prep, and customer responsibilities."

That gives the customer confidence that the job will move into an organized process.

Build a reusable company standard

The best use of an AI proposal builder is not one-off drafting. It is building a consistent company standard that every customer sees.

That standard should answer the same core questions every time:

• What problem is the customer trying to solve?
• What work are you recommending?
• What is included?
• What is excluded?
• What options does the customer have?
• What does the price cover?
• What happens after approval?

Once those sections are consistent, each proposal still needs job-specific details, but the structure no longer changes from person to person. That matters if more than one estimator writes proposals. It also matters if you are the owner and you write proposals late at night after a full day in the field.

A reusable standard helps prevent thin proposals. It also helps prevent overpromising. If every draft has a visible assumptions section, a visible exclusions section, and a clear approval step, you are less likely to send a quote that creates confusion later.

The goal is not to make every proposal sound identical. The goal is to make every proposal complete enough that a customer can compare it fairly and approve it without wondering what is missing.

Review the proposal before sending

AI can make a proposal look finished before it is actually ready. Slow down for five minutes and check the pieces that create the most disputes.

Do not send until:

• The customer name and address are correct.
• The scope matches what you actually priced.
• Labor and materials are not double counted.
• Exclusions are visible.
• The timeline is realistic.
• Payment terms are clear.
• Any warranty language matches what you really offer.
• The customer has one obvious next step.

If something is uncertain, write it as an assumption. Example: "Proposal assumes existing electrical service is sufficient for the replacement equipment." That is more professional than burying the risk or hoping it does not come up.

Where Roxy fits

Roxy is useful when you already have the job details and need a faster way to turn them into a clean proposal draft. Instead of starting from a blank document, you can enter the project information and generate a contractor-ready proposal you can review, edit, and send.

Use Roxy when you want to:

• Create a proposal from job notes
• Standardize scope language across jobs
• Build trade-specific proposal drafts
• Move faster after a site visit
• Avoid rewriting the same proposal sections every week

The Free plan gives contractors up to 10 Roxy-branded proposals every 30 days. If proposal volume grows, Pro is $49/mo.

Roxy is not trying to replace your estimate, your walkthrough, or your judgment. It is there for the part of the work that usually happens after hours: turning scattered notes into a proposal that reads clearly, follows a reliable structure, and gives the customer a next step.

The bottom line

A free AI proposal builder is not a magic estimator. It is a drafting tool for contractors who already understand the work and want to present it clearly.

Bring the facts. Be honest about assumptions. Spell out the scope and exclusions. Then use Roxy to turn that information into a proposal draft you can send with more confidence.
