AI proposal generator for your business

Quotes, estimates and proposals are different jobs

A quote is a price for a clear request: 500 flyers, a fence repair, a shipment. It should be fast, and it is often automated end to end. A proposal is a document that wins a larger job. It explains what you understood about the client’s problem, what you will do, how, when, who is involved, what it costs and on what terms. A detailed estimate sits underneath it, breaking the work into line items, quantities, labor and materials.

Proposals and estimates take hours because they are mostly assembly: finding the right past proposal, copying sections, rewriting them for this client, rebuilding the numbers and checking nothing was left from the last job. That is the part an AI proposal generator takes on, while your team keeps the judgment.

What an AI proposal generator puts together

• A tailored summary of the client’s situation and goals, written from your discovery call notes or site visit.
• Scope and approach sections assembled from your library of past proposals, rewritten for this project.
• A schedule and milestones based on how long similar jobs have actually taken you.
• Team bios, relevant past projects and certifications pulled from content you have already approved.
• Pricing tables built from your estimate, with options or tiers if you offer them.
• Your standard terms, exclusions and assumptions, with project-specific changes highlighted for review.
• Answers to RFP questions drafted from previous responses, marked where a person needs to check or fill in.

AI estimating software for detailed jobs

For contractors, engineers, agencies and other project businesses, the estimate is where the risk is. AI estimating software reads the inputs, such as scope documents, drawings, spec sheets, photos or a walkthrough recording, and proposes line items, quantities and assemblies using your own cost database and labor rates. It compares the result with similar past jobs and flags anything that looks high, low or missing.

The AI does not set your prices. It suggests quantities and items, and your rules calculate the numbers. An estimator reviews every line, adjusts it and signs off, and those corrections feed back into the next estimate. Drawings and scans can be misread, so anything uncertain is marked rather than quietly filled in.

Custom build vs. PandaDoc, Proposify and ChatGPT

Proposal tools like PandaDoc, Proposify and Qwilr handle templates, e-signatures and tracking well, and several now include AI writing help. If your proposals are mostly a template with a few fields, one of them is probably all you need. Construction estimating products such as STACK or ProEst suit firms whose work matches how they are built. Pasting notes into ChatGPT or Claude by hand can produce a decent first draft, but it does not know your rates or past work, and someone still has to check every number and sentence.

A custom AI proposal generator fits when proposals draw on your own library of past work, your pricing logic and data from other systems, such as your CRM, project history or cost database. It produces documents in your format and voice, and can work alongside the proposal or e-signature tool you already use.

How we build it

1. Gather your best proposalsWe collect past winning proposals, estimates, rate cards and standard terms, and note what each section is for.
2. Map your estimating logicWe write down how your estimators turn scope into line items, quantities, labor and prices.
3. Design the workflowYou click through how a proposal is started, drafted, reviewed, edited and sent.
4. Build in roundsWe build the generator in stages and test it on recent jobs where you already know the right answer.
5. Review before sendEvery proposal and estimate goes through a person, with uncertain sections clearly marked.
6. Improve with each jobEdits, wins and losses feed back, and we keep adjusting content and rules over time.

What it costs

Zoti custom projects start at $499/month on a monthly plan that covers design, development, hosting and ongoing changes. The price depends on how many proposal types you produce, how detailed your estimates are and which systems we connect. AI usage fees depend on volume and are explained up front. You get a written quote before any work begins.
