AI Agents for General Contractors: From Plain-Language Site Notes to a Cost-Coded Draft in Your Queue

The Bottleneck in Your Business

You just walked a client's half-finished basement. Your phone is full of photos, your head is full of framing, electrical rough-in, and a new egress window. The client is in the doorway asking, "So when can I get a number?"

The honest answer for most GCs is: "Give me a few days." Between that walkthrough and a clean, cost-coded proposal in the client's inbox sits a block of office time—pulling line items, checking markup, formatting the document, making sure every cost code matches how your firm actually bills. Your crew is on the next job. Your estimator is buried in three other quotes. The walkthrough energy is fading.

The specific gap this article addresses is the transformation step: turning the unstructured notes you jotted on site into a structured, cost-coded, material-priced proposal draft that sits in your approval queue. Not the client-facing delivery (covered in our earlier walkthrough article), not the queue mechanics in isolation, but the building process itself—how plain language becomes your firm's exact line-item format.

PLMBR's AI agent, Felicity, is built for this transformation. You tell her what you saw in plain language, and she drafts the proposal using your cost codes, your markup, and your line-item format—learned from your own past jobs PLMBR for contractors. The draft sits in your queue. Nothing reaches the client until you tap approve.

How PLMBR AI Agents Help With This Workflow

Here is the documented sequence from the contractor workspace:

1. You tell Felicity what you saw. In plain language, by text or email, right inside PLMBR. "Basement: 12×18 room, new egress window, electrical rough-in for two outlets and a light, concrete floor patch." That is the input PLMBR for contractors.

2. She structures it into your cost codes. Felicity drafts the exact proposal you would—your cost codes, your markup, your line items—learned from your own past jobs. The product page describes the output as "same numbers, same format, ready to send" PLMBR for contractors.

3. She can pull material costs while she builds. The workspace notes she can order materials from your own supplier accounts while she builds the estimate, on her own or with one-button approval PLMBR for contractors.

4. The draft waits in your queue. She drafts and queues; nothing reaches a client and no invoice moves until you tap approve. You approve, edit, or reject before a word goes out PLMBR for contractors.

5. Financials sync to QuickBooks. Every job, expense, and invoice flows into QuickBooks automatically, so your books stay current without a separate bookkeeping step PLMBR for contractors.

The key distinction: Felicity is not generating a generic AI estimate. The product is designed around your firm's existing cost structure, so the output matches how you already build quotes.

The Business Inputs and Existing Tools to Discuss During Onboarding

Before Felicity can draft a proposal that looks like yours, your team will walk through a few things during onboarding:

• Your cost codes and markup structure. This is the backbone. Felicity learns your line-item format from your past jobs, so having representative completed proposals available matters.
• Gmail. The product connects to your Gmail for client communication. Your leads still come from Gmail; Felicity handles the drafting and follow-up in your voice PLMBR for contractors.
• QuickBooks. Every job, expense, and invoice flows into the QuickBooks you already run PLMBR for contractors.
• Google Calendar. Listed as a connected tool on the product page PLMBR for contractors.
• Your supplier accounts. If you want Felicity to pull material pricing while she builds the estimate, your supplier account access is part of the setup PLMBR for contractors.

Bring a representative sample of past proposals to the onboarding conversation. That gives the team a concrete reference for how your firm structures line items, applies markup, and formats the final document.

Workflow at a Glance

Owner Review, Exceptions, and Human Takeover

PLMBR's contractor workspace is approval-gated by default. The product page states: "She drafts and queues; nothing reaches a client and no invoice moves until you tap approve" PLMBR for contractors.

In practice, this means:

• You see the full email in the queue for follow-ups and invoices before approving. For proposal drafts specifically, ask in the demo what the queue displays and how much detail is visible before you tap approve.
• You can edit or reject. If a line item is off, or the scope description does not match what you saw on site, you fix it in the queue before approving.
• Material orders have a separate approval path. Felicity can order from your supplier accounts on her own or with one-button approval, depending on how you configure it PLMBR for contractors.
• Client communication stays gated. Felicity talks to clients in your voice, connected to your Gmail, but nothing reaches a client and no invoice moves until you tap approve PLMBR for contractors.

If something falls outside what you have configured—say, a scope item you have not cost-coded before—you step in, adjust the draft, and approve. The system does not force a decision you have not made.

An Illustrative Job: What to Test in a Demo

This is a demonstration scenario, not a customer case study. The inputs below are invented to give you a concrete script for a product walkthrough.

The job: A client is adding a 10×12 sunroom off the back of a 1990s ranch. Scope includes a new concrete slab, framing, a 4×8 sliding glass door, two single-hung windows, electrical for two recessed lights and a ceiling fan, and interior drywall and paint.

Customer inputs to bring to the demo:

• A short text or email you would actually send: "Sunroom add, 10×12, new slab, frame, 4×8 slider, two windows, 2 recessed + fan, drywall/paint. Client wants a number by Friday."
• Your firm's cost codes for slab work, framing, windows, electrical rough-in, and finish.
• A sample of a past proposal in your format.

Questions to test in the demo:

• "If I send that text, what does the first draft look like in my cost codes?"
• "Can I see the approval queue with this draft waiting?"
• "If I change the window size from 4×8 to 4×6, does the line item update?"
• "What does the QuickBooks sync look like once I approve and the job starts?"

These are questions to ask during a live walkthrough, not assertions about how the product will behave on your specific job.

How to Evaluate This Workflow

Does this match how my firm actually builds proposals?

The product is designed around your existing cost codes and markup, learned from your past jobs PLMBR for contractors. If your firm uses a standardized cost-code structure, the fit is direct. If your proposals are highly bespoke per project, ask in the demo how Felicity handles a scope that does not match a prior job's structure.

What do I need to have ready before the first walkthrough?

You will want your cost codes, a sample of past proposals, and access to your Gmail and QuickBooks accounts. The product page lists QuickBooks, Gmail, and Google Calendar as connected tools PLMBR for contractors. Bring those and a representative job to the onboarding call.

How does the approval queue work if I am on site and cannot open a laptop?

The product page states you can talk to Felicity "by text or email" and that she takes action "right inside PLMBR" PLMBR for contractors. Ask in the demo whether you can approve or edit a queued proposal from a phone while you are walking a site.

What happens if I reject a draft?

The documented flow is approve, edit, or reject PLMBR for contractors. Ask in the demo what happens to the draft after rejection—whether it is discarded, saved as a version, or returned for revision.

Next Step and Demo Invitation

Start by evaluating PLMBR when turning plain-language site notes into a structured, cost-coded proposal draft is your priority. The PLMBR contractor workspace brings together your sales pipeline, proposals, job finances, and Felicity in one view. You can watch a product walkthrough to see the proposal draft, cost codes, and approval queue in action before you commit to a call.

Book a 15-minute demo and bring a real walkthrough from your last job. We will show you how Felicity takes your notes and builds the proposal in your cost codes, and you will see the approval queue with the draft waiting for your tap. No card required—just a calendar invite by email.
