AI quote generator

An AI quote generator
that prices from your own rates.

Unibuild’s AI builds a quotation or estimate from the enquiry documents you upload, or from a prompt describing the job. Your estimator edits it, the AI checks it, and a named person approves it before it goes.

In plain terms

An AI quote generator turns an enquiry into a priced quotation. In Unibuild, the AI reads the drawings, specification and schedules the client sent, or a prompt from the estimator. It builds the estimate and quotation from your own price library.

The quotation is then a normal Unibuild quotation. It is edited by hand, checked by the AI against the enquiry, approved by a named person and issued on your letterhead. When the client approves it, it becomes the live project. The whole module is on quotations and tenders.

How it works

The enquiry in.
A quotation you approve out.

The AI does the reading and the first pricing pass. Your estimator makes the decisions, and nothing is sent until a named person approves it.

Upload the enquiry, or write a prompt

Attach the drawings, specification, schedule of works or the client’s email to the enquiry. For a small job, describe the work in plain words instead.

The AI builds the estimate and quotation

The AI prices the work from your Advanced Estimating library, in sections for materials, labour, testing, strip out, preliminaries and other charges, with a description of each service.

Edit any line by hand

The estimator changes quantities, rates, descriptions and markup wherever they want. Every edit is logged, and your cost and margin never reach the client’s copy.

The AI checks it before it goes

Spelling, grammar, prices and service descriptions are read back, and the quotation is verified against the enquiry documents. Anything that does not match is flagged for the estimator.

Approve and issue

A named person approves it. It leaves as a branded PDF on your letterhead, and the client can approve it online in the client portal.

Won, then converted

A won quotation converts into a live project in one action, carrying the client, site, scope and values across. The job is then measured against the price that won it.

After the first draft

Six things that keep a quotation
earning after it is written.

Writing the price is the first step. These are the steps where a firm usually loses the time or the margin it saved.

Duplicated

A large estimate perfected over days becomes the starting point for the next similar job. Duplicate it, change what is different, and send.

Work outside the original agreement is raised as a variation, recorded against the project and invoiced to the client.

When the client approves a further quotation on a live project, it joins the project as a variation and the project value updates.

Three ways to price one

In a spreadsheet, in a general AI chat tool,
or built inside the quoting system.

Writing the quotation is one step of several. This is what each way leaves you with.

How the AI is charged

Pay for the AI you use.
Nothing added.

The cost of AI is bespoke to each firm. You pay only for what you use, and we set it out in the demo.

Everyday AI, included: The AI that runs through the platform day to day is part of the monthly fee, like every other module.
Heavier AI, at cost: High-value AI work is paid as you use it, at the AI provider’s own rate. Unibuild adds nothing on top.
Your choice of model: You choose which AI model does the work, and you can change your mind later.
Your own AI account: If your firm already pays for an AI service, connect it. The provider bills you directly.

How model choice and your own AI account work

Built around your firm

Your rates, your templates, your letterhead.

Unibuild is bespoke business software for UK trades and specialist contractors: a platform in daily production since 2016, shaped to the way each firm already works.

Your price library: Unibuild migrates your price files during onboarding, so the AI prices from your suppliers, fit times and labour rates. Changes after go-live are included in the monthly fee. That is how bespoke software works here.
Your quotation layout: Your logo, address, numbering, terms and standard exclusions, on every quotation the AI builds and every one your estimators write.
One fee: One monthly figure for the firm, sized when it is quoted and fixed for three years. Unlimited users, so every estimator is included.
Extra work on site: Engineers price extra work in your own staff app, from the job’s rates, and the client signs it there.

Questions

Asked before the AI
prices the first job.

Can AI write a construction quote?

Yes. In Unibuild, the estimator uploads the enquiry documents or writes a prompt describing the job, and the AI builds the estimate and the quotation. The estimator then edits it, the AI checks it, and a named person approves it before it is sent.

What can the AI build a quotation from?

From the documents attached to the enquiry, such as drawings, a specification, a schedule of works or the client’s email. Or from a prompt written in plain words, which suits a small job or a quick budget price.

Does it use our own prices?

Yes. The AI prices from your Advanced Estimating library: your suppliers, your fit times and your labour rates, each dated. Unibuild migrates your price files as part of onboarding.

Can we duplicate a quotation or estimate?

Yes, in one click. The copy keeps every section, line, quantity and description, and the estimator changes only what is different for the new job. The original stays on its own record, with its own revisions. The AI check reads the copy before it goes, so details from the old job are caught.

What does the AI check before a quotation is sent?

Spelling, grammar, prices and the description of each service. It also verifies the quotation against the original enquiry documents and anything else the client sent for the project. Missed scope, wrong quantities and details from another job are flagged. AI estimate review sets out every check.

Does the AI send quotations on its own?

No. A named person in your firm approves every quotation, and the approval is recorded with their name and the date. The AI builds and checks. Your people decide the price.

What happens when the client accepts?

The quotation or estimate converts into a live project in one action. The client, site, scope, sections, materials, labour and values carry across, with the same reference. The job is measured against the price that won it.

Will it warn us when a job goes over the estimate?

Yes. Unibuild tracks the work against the agreed quotation, estimate or contract. Materials are counted to the last quantity, labour hours come from the timesheets, and site documents are verified against the estimate. When cost or scope grows past what was agreed, it is flagged. Cost control shows the position on every job.

How is out-of-scope work charged?

Work outside the original agreement is raised as a variation, recorded against the project and invoiced to the client. A further quotation the client approves on the same project joins it as a variation too, and the project value updates. Variations covers both.

Will the client see our costs or margin?

No. Your cost, markup and build-up stay on your side. The client receives a typeset PDF on your letterhead showing what you have decided it should show.

Does it build estimates as well as quotations?

Yes. The AI builds both, and both can be duplicated, checked and converted into a project in the same way. Quote or estimate explains which one binds you.

How much does the AI quote generator cost?

It is part of Unibuild’s monthly fee, with no separate module fee and no charge per user. The fee covers unlimited users, configuration, training and price library migration, and is fixed for three years. Heavier AI work is paid as used, at the AI provider’s own rate. How AI is charged.
