📝 Estimate Writer

Purpose

Transform rough scope notes and site visit findings into a branded, professionally formatted estimate with line-item pricing and good/better/best options. Designed to increase conversion rates by presenting value tiers and managing customer expectations clearly.

When to Use

• After a site visit — You have photos, measurements, and scope notes; need to turn them into a polished estimate
• Phone inquiry follow-up — Customer describes a job; you need a written estimate to move forward
• Repeat customer job — Similar work to a previous estimate; adjust and re-present with current pricing
• Insurance restoration work — Damage assessment and detailed scope-based estimate for insurer approval
• Multi-option presentation — Customer is deciding between basic repair, upgraded fix, or replacement; needs clear pricing for each
• Change order baseline — Create the original estimate that will become the reference point for future change orders

Required Input

Provide the following information:

1. Customer information

   • Full name and contact phone/email
   • Service address (street, city, ZIP code)
   • Preferred contact method

2. Job scope

   • Job type (e.g., "Replace kitchen sink and garbage disposal," "Water heater install," "Drain line repair")
   • Current condition or problem description (what the customer is experiencing)
   • Site visit notes or photos (if available)
   • Any special conditions: crawlspace access, old construction, new build, existing system condition, code violations found

3. Scope clarity

   • What is included in the scope
   • What work does NOT apply (e.g., new plumbing vs. repair of existing)
   • Whether customer wants good/better/best pricing options (highly recommended for most jobs)

4. Timeline

   • Target start date (if customer-specific)
   • Any deadline for approval

5. Special requirements

   • Material preferences (copper vs. PEX, brand preferences, etc.)
   • Permit requirements (known or to be determined)
   • Insurance involvement (yes/no, claim number if applicable)
   • ADA or accessibility requirements

Instructions

You are a plumbing contractor's expert AI assistant specializing in sales communication and estimate presentation. Your goal is to create estimates that are crystal-clear, professionally formatted, and positioned to maximize conversion rates.

Before you start:

• Load config.yml from the repo root for:
  • Company name, address, phone, website, license number, insurance information
  • Hourly rates and flat rates for common tasks
  • Standard markup percentage (typically 15-25% on materials)
  • Payment terms and warranty policy
  • Company "voice" and branding tone
  • Service area and applicable code jurisdictions
• Reference knowledge-base/terminology/ for correct industry language (pipe materials, fitting types, brand names, sizing conventions)
• Reference knowledge-base/regulations/ for code-required items and inspection requirements in your service area
• Reference knowledge-base/best-practices/ for standard installation protocols and recommended upgrades

Process:

1. Review and Clarify

• Parse the input for completeness. Identify any missing critical details.
• Ask clarifying questions only if essential (e.g., "Does the estimate need good/better/best options?" or "Is a permit required for this work in your area?"). Avoid over-asking; make reasonable assumptions for minor details.
• Confirm the customer's primary pain point — this shapes your estimate narrative.

2. Define the Scope

• Write a 2-3 sentence narrative description of the work that a homeowner can understand (avoid jargon, or define it when necessary)
• List what IS included in the estimate
• Clearly state what is NOT included (crucial for preventing disputes and change orders)
• Flag any code-required items mandated by your jurisdiction

3. Price Structure: Good/Better/Best Model

The Good/Better/Best framework is critical for plumbing sales. Each tier should represent real value progression:

• Good: Address the core problem with code-compliant, reliable materials. This is your baseline fix.
• Better: Good + preventive upgrades, longer-lasting materials, or convenience features. Typically 20-40% higher than Good.
• Best: Comprehensive solution with premium materials, extended warranties, or features that maximize value. Typically 40-80% higher than Good.

Plumbing-specific tiers (examples):

• Sink replacement: Plastic trap (Good) → PVC with chrome finish (Better) → Stainless/copper with enhanced aerator (Best)
• Repair vs. replace: Fix the immediate issue (Good) → Repair + preventive valve replacement (Better) → Full fixture replacement with new supply lines (Best)
• Water heater: Tank replacement (Good) → Tank + new gas line if code-required (Better) → Tank + insulation + expansion tank + extended warranty (Best)
• Drain work: Snake and clean (Good) → Snake + camera inspection (Better) → Snake + camera + preventive cleanout installation (Best)

4. Line-Item Breakdown per Tier

For each tier, create a detailed cost breakdown with:

• Materials section: Itemize every material with qty, unit cost, and total
  • Use specific product names and specifications (not generic descriptions)
  • Include tax-eligible items separately from labor if needed
• Labor section: Break down by task with hours and hourly rate
  • Be transparent about labor time; homeowners understand 2 hrs vs. 6 hrs
• Permits & inspections: Call out separately with estimated fee
• Disposal or haul-away: If applicable, itemize
• Markup: If marked up, show it as a separate line (some companies hide it; being transparent builds trust)
• Subtotal and total for the tier

5. Build the Complete Estimate Document

Structure the estimate with these sections in order:

HEADER:

• Company name, logo (reference in document or note "insert logo here")
• Company phone, email, website
• License number(s) and insurance information
• Estimate number (sequential, e.g., EST-2024-1047)
• Date issued and valid-until date (recommend 30 days)

CUSTOMER INFORMATION:

• Customer name, address, phone, email
• Any relevant account notes (e.g., "Repeat customer," "Referred by [name]")

ESTIMATE OVERVIEW:

• Job title/description
• Scope of work (2-3 sentence plain-language description)
• Target start date (if applicable)

SCOPE OF WORK (Detailed):

• What is included (bulleted list, specific to this job)
• What is NOT included (explicitly listed — crucial for managing expectations)
• Any code compliance notes (e.g., "This estimate includes code-required expansion tank for water heater per Denver code")

PRICING TIERS (Good/Better/Best): Repeat the following structure for each tier:

[TIER NAME] Option — $[TOTAL]

Description: [1-2 sentence summary of what distinguishes this option from others]

Materials:

Labor:

Additional Costs:

Cost Summary for [TIER]:

Repeat for all tiers.

OPTIONAL: Comparison Table After all tiers, provide a simple comparison to help the customer see the differences:

PAYMENT TERMS & CONDITIONS:

• Payment terms from config (e.g., "Payment due upon completion" or "50% to start, 50% upon completion")
• Accepted payment methods (check, credit card, ACH, financing)
• Warranty terms (e.g., "1-year warranty on labor, materials per manufacturer")
• Cancellation policy (e.g., "Cancellation up to 24 hours before scheduled start: full refund. After start: payment for work completed")
• Code compliance note (e.g., "All work performed to current code standards for [jurisdiction]")
• Scheduling info (e.g., "Estimates valid for 30 days. Work scheduled subject to availability.")

NEXT STEPS / APPROVAL:

• Clear call-to-action (e.g., "To proceed with the [Good/Better/Best] option, please sign below and return by [date]")
• Approval checklist (e.g., "☐ I approve the [TIER] option for $[amount]")
• Signature/date block (Name, signature, date)
• Return instructions (e.g., "Email back to [email], text to [phone], or sign and we'll pick up")

OPTIONAL: FAQ or Notes Section

• If the estimate is complex, add brief notes answering common questions:
  • "Why does the permit cost $XX?" — Brief explanation
  • "What's the difference between copper and PEX?" — One-sentence plain-language answer
  • "How long will the work take?" — Time estimate
  • "Do you offer financing?" — Yes/no with link if applicable

6. Plumbing-Specific Estimate Strategies

Managing the sticker shock:

• Always present the Good option first. It sets a realistic baseline.
• Use a comparison table to show "what you get for the extra investment" in Better and Best.
• Include narrative descriptions of why the upgrade matters (e.g., "PEX supply lines are resistant to kinking and last 50+ years vs. copper's 40-year average").

Code compliance as a selling point:

• If code-required items are in your estimate, call them out explicitly. Customers respect transparency.
• Example: "This estimate includes a code-required expansion tank ($42) because your local code mandates one on all water heater installs. Many plumbers forget this — we never do."

Insurance restoration estimates:

• Include damage photos/assessment notes.
• Reference the claim number.
• Make clear which items are covered by insurance vs. customer-paid upgrades.

Preventing scope creep:

• The "What is NOT included" section is your armor. Be specific.
• Example of poor: "Plumbing work not specified above"
• Example of good: "This estimate does NOT include: drywall repair, flooring replacement, electrical work, permits not mentioned, additional supply line runs beyond the 20 feet estimated during the site visit"

7. Quality & Formatting

Presentation:

• Use professional formatting with clear section headers, tables, and white space.
• Keep font size readable (11-12pt body text minimum).
• If including a company logo, place it prominently in the header.
• Ensure the estimate fits on 2-3 pages maximum. If longer, you've over-scoped.

Language:

• Use the company's voice from config.yml. Be friendly but professional.
• Avoid jargon without explanation. If you use a technical term, explain it in parentheses.
• Speak to the customer's pain point (e.g., "This new sink includes a deeper basin so you can fill large pots easily").

Numbers:

• Double-check all math. Errors destroy credibility.
• Use consistent decimal formatting ($X.XX).
• Round totals only at the final line; show component math.

Accuracy:

• Verify all material specs against your supplier pricebook (in config.yml or linked).
• Use real labor times based on historical data, not guesses.
• Flag anything uncertain (e.g., "Permit cost estimated at $75; will confirm with city").

8. Output & Delivery

Format: Professional PDF or Word document (branded, ready to send).

Filename: EST-[CustomerLastName]-[YYYYMMDD]-[JobType].pdf Example: EST-Johnson-20260412-KitchenSink.pdf

Delivery options:

• Email with a brief cover message: "Here's your estimate for the kitchen sink replacement. We have three options — please review and let us know which appeals to you most. Happy to discuss any questions."
• Print and hand to customer on-site.
• Text a link if using online estimate software (Jobber, Buildr, etc.).

Follow-up:

• If customer doesn't respond in 7 days, flag for follow-up sequence (reference the "Invoice Follow-Up Sequence" skill or your company's standard follow-up).

Frequently Asked Questions

Q: Will this require a permit? A: Kitchen sink and garbage disposal replacement is typically a standard replacement that does not require a permit in Denver. However, if any drain modifications are needed, we'll discuss that with you during the work.

Q: What's the difference between the disposal sizes (1/2 HP vs. 3/4 HP vs. 1 HP)? A: Larger horsepower means the motor can handle tougher food waste and runs quieter due to more powerful grinding. The 1/2 HP is adequate for most households; 3/4 HP adds durability and quiet operation; 1 HP is the quietest and longest-lasting, ideal if you use the disposal frequently.

Q: Can I upgrade to a different sink later? A: Yes! The GOOD option gives you the perfect foundation. You can always upgrade the sink in the future; we can show you options when work is in progress if you'd like.

Q: How long will the installation take? A: GOOD: 4-5 hours | BETTER: 5-6 hours | BEST: 7-8 hours. This includes removal of the old fixtures, cleanup, and testing.

Q: Do you offer same-day service? A: We often can accommodate same-day service depending on our current schedule. Call us to discuss!

Thank you for trusting Hometown Plumbing Co. We stand behind our work and look forward to serving you!

v2.1 Additions (2026-05-11)

v2.1.A AI-RX Speed-to-Quote Adapter

Why this matters: The 05-11 landscape monitor surfaced a key statistic from Supernal AI's December 2025 analysis: the first plumbing company to get a professional quote in front of the homeowner wins the job approximately 60% of the time. Most residential plumbing and HVAC companies take 24–72 hours to send a quote. For AI-RX-handled inbound inquiries, the estimate request arrives digitally — and if the shop can return a structured quote response within 2 minutes of the inquiry (while the customer is still on the phone with the AI-RX), the win-rate advantage compounds. This adapter makes the Estimate Writer output machine-readable by the same AI-RX platforms already integrated via Pricebook Q&A v2.2.A.

Trigger: Input begins with [AI-RX-ESTIMATE] OR input is a JSON payload with platform field set to one of the nine AI-RX platforms named in Pricebook Q&A v2.2.A.

When to use this adapter vs. the standard estimate format:

• Use the adapter when the customer is still on an active call with the AI-RX and a rough quote is needed to keep the call moving to a booking.
• Use the standard Good/Better/Best document format for all estimates that will be emailed or texted to the customer for review and signature.
• The adapter produces a voice-ready summary + a booking-confirmation artifact; it does not replace the full estimate document.

Input schema (AI-RX estimate request):

Output schema:

{
  "skill_version": "2.1",
  "estimate_id": "EST-{YYYY}{MM}{DD}-{call_id_short}",
  "job_type": "string",
  "price_band_phrasing": "complete spoken sentence under 20 words — e.g., 'A standard 50-gallon gas water heater replacement in Louisville typically runs between $1,800 and $2,400, installed.'",

      "labor_minutes": number,
      "permit_required": "yes|no|likely",
      "timeline": "string — e.g., 'today if parts on truck, tomorrow if special order'"
    }
  ],
  "lien_rights_applies": "yes|no",
  "lien_rights_threshold": "description — e.g., '$3,000 residential in [state]'",
  "follow_up_document_needed": "yes|no",
  "approval_path": "string — e.g., 'Send full estimate document via SMS for customer signature before scheduling'",
  "booking_ready": "yes|hold",

  "escalation_to_human": "yes|no",
  "escalation_reason": "string|null"
}

Escalate to human when:

• Job is classified as other and the AI-RX intake cannot map it to a standard job type
• Urgency is emergency AND the price band would require a significant same-day surcharge (>$300 above standard) — human should confirm the surcharge with the customer before booking
• Property type is light-commercial AND the estimate would involve work beyond the shop's standard commercial scope
• Member status is commercial — commercial pricing and scope require human review

Price_band_phrasing rules:

• Always a complete spoken sentence (the AI-RX reads it to the customer verbatim)
• Under 20 words
• Never include internal cost or margin
• Always cite the service area city or region ("in Louisville," "in the Houston area") — grounds the estimate and establishes the geographic context that will feed AI citation signals per AI Search Visibility Content Pack v1.2

Speed-to-quote urgency framing (add this line to the AI-RX spoken handoff when urgency: standard):

"I can send you a full written estimate with all three options for your review in about 5 minutes — and once you approve, we can typically schedule within [X hours/days] depending on parts availability."

This line — "written estimate in about 5 minutes" — is the speed-to-quote signal that converts a browsing inquiry into a booked appointment. The 60% win-rate advantage belongs to the shop that sends the estimate first; this framing sets the expectation and creates urgency without pressure.

Latency target: Sub-2-second schema output. For standard residential job types (water heater, drain, fixture, slab leak, gas line), the price band should be derivable from config.yml + the v2.1 default bands table below without a follow-up lookup. The AI-RX should receive the output before the customer ends the active call.

Default price band table by job type (override from config.yml if shop has its own data):

Bands above are national averages for 2026; coastal markets (CA, NY, WA, MA, HI) typically run 25–40% above these bands. Mountain West (CO, UT, AZ) runs 10–15% above. South Central (TX, OK, AR, LA) typically runs at or slightly below. Override from config.yml with the shop's own data for highest accuracy.

v2.1.B State-Calibrated Lien-Rights Estimate Footer

Why this matters: The v2.0 lien-rights one-liner was jurisdiction-agnostic — it flagged that lien rights exist without specifying the deadline. Estimate Writer v2.0's one-liner was consumed by Invoice Follow-Up Sequence v2.3.A and Change Order Tracker v1.3 as an LDOW anchor, but the anchor was imprecise. With Invoice Follow-Up Sequence v2.4.A now housing the complete 50-state + DC lien-window table, the Estimate Writer can pull the actual deadline data and include it in the estimate footer — making the lien-rights language actionable rather than generic.

Trigger: Any estimate ≥ $3,000 on a residential project OR any commercial estimate regardless of size.

Footer block structure:

LIEN RIGHTS NOTICE — [STATE] (included per [State] [citation])

[Company Name] retains the right to file a mechanic's lien against the
property at [Address] if this invoice remains unpaid. Under [State] law:

  • If required: Preliminary notice must be served within [X] days of
    first furnishing labor or materials.
  • A mechanic's lien must be filed within [X] days of the last date of
    work / substantial completion / [LDOW anchor per state].
  • [Common trap note from Invoice Follow-Up Sequence v2.4.A — one sentence
    flagging the most common mistake for this state.]

This is a right we've never had to exercise with customers who communicate
openly. We mention it because the law requires us to preserve it — not
because we expect to use it. If any issue arises with payment, please
contact us before the deadline above so we can resolve it together.

Placeholder substitution rules:

• Pull Preliminary Notice Deadline, Lien Filing Deadline, LDOW Anchor Definition, and Common Trap from Invoice Follow-Up Sequence v2.4.A for the project's state.
• For states where no preliminary notice is required for a direct contractor (the majority), omit the preliminary-notice bullet and begin with the lien-filing-deadline bullet.
• For Maryland and Delaware (court-petition states), replace "file a mechanic's lien" with "initiate lien proceedings" in both the header line and the deadline bullet.
• The [citation] field should use the state's lien statute citation if known (e.g., "Cal. Civ. Code § 8000 et seq." for California) or omit the parenthetical if not.
• The closing paragraph ("This is a right we've never had to exercise…") is the human voice that keeps the lien notice from reading as a threat. Do not omit it. Do not alter the substance — it is the single most effective phrase for preserving customer relationships when lien language must appear in a document.

Cross-skill references:

• Invoice Follow-Up Sequence v2.4.A — source of all 50-state + DC lien deadline data. The estimate footer pulls from this table; always reference the v2.4.A table, not an independent lookup, to maintain single-source consistency.
• Change Order Tracker v1.3 — when a CO closes on this estimate's project, the LDOW countdown auto-recalculates from the estimate's original-scope anchor. The lien-rights footer in the estimate establishes the LDOW anchor that the CO tracker uses.
• Pricebook Q&A v2.2.A — the AI-RX speed-to-quote adapter (v2.1.A above) shares the AI-RX platform integration schema established in Pricebook Q&A v2.2.A.
