Contractorquote

What Contractorquote is for

"Break down this estimate: $3,000 labor, $2,000 materials, 10% overhead, targeting a 20% margin", "what's a 25% markup in margin terms?", "how does a contractor change order actually work?", "what's a normal payment schedule for a $20,000 remodel?", "how do I spot a bad contractor quote?" — answered with real arithmetic and a hand-curated reference, on both sides of a contractor estimate — no upstream calls, nothing stored.

What it does

estimate_breakdown_calculator builds a full labor/materials/overhead/profit breakdown and computes the total price by markup (profit as a percent of cost) or margin (profit as a percent of the selling price) — the single most common point of confusion in contractor estimating, since a 25% markup and a 25% margin are different numbers (a 25% markup is only a 20% margin), and the tool always reports the equivalent value in the other convention so you can catch the mistake before it costs you money. markup_margin_converter is the standalone conversion, using the identities margin = markup/(1+markup) and markup = margin/(1-markup). change_order_process_explainer covers the general steps for handling a change order: identifying the trigger, documenting it in writing, pricing the cost/schedule impact, and — critically — getting written approval BEFORE the additional work begins. payment_schedule_template gives a deposit/progress/final billing pattern by project size (a simple 50/50 split for a small job, up to a five-milestone structure for a large remodel), with dollar amounts if you supply a total price. red_flags_checklist is a consumer- facing list of warning signs in a contractor quote: unusually low bids, large cash-only deposits, no license/insurance, high-pressure tactics, missing permits, and vague payment terms. estimate_glossary defines change order, punch list, retainage, scope of work, markup, margin, lien waiver, mechanic's lien, substantial completion, and allowance.

What it is not

General trades reference information and arithmetic, not legal advice. Deposit-amount limits, licensing requirements, permit rules, and lien/contract law all vary by trade and by state or local jurisdiction — Contractorquote does not know which rules apply to a specific real job. Confirm the actual contract terms and, where a real dispute or large dollar amount is involved, consult a professional or your local licensing board.

Contractorquote — Privacy Policy

Effective 28 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Contractorquote is. Contractorquote is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf to compute contractor-estimate figures and provide general reference information: estimate breakdowns, markup/margin conversions, payment schedules, and quote red flags. You interact with your assistant; the assistant sends us only the numbers needed for that one calculation.

What we receive. The arguments of each tool call — typically labor/materials costs, a markup or margin percentage, or a total contract price — the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Nothing you submit is stored or logged. Every calculation is computed fresh from the numbers you provide in that single request — Contractorquote does not maintain a project history, a client list, or a running estimate for you. No query — including any cost, price, or project detail you enter — is logged in request bodies, recorded, or used to train anything.

What we do not receive or store. We do not receive your conversation with the assistant, contractor or client names, addresses, or any account or financial-account information, and we do not build a profile from your queries: each request is answered independently. Rate-limit counters (a client identifier and timestamps, never the request content) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. None — every tool is computed locally. Hosting: Vercel (United States regions).

Legal bases and your rights. Our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived, content-free logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Contractorquote is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.

Contractorquote — Terms of Service

Effective 28 September 2026. These terms govern use of the Contractorquote connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

1. The Service. Contractorquote returns contractor-estimate calculations — labor/materials/overhead/ profit breakdowns, markup/margin conversions, payment-schedule splits — plus general reference guidance on change orders and consumer-facing red flags, computed or looked up from the information you provide in each request. It is accessed through an AI assistant or directly over MCP or HTTP.
2. Not legal advice. Contractorquote's output is general arithmetic and reference guidance for the trades, not individualized legal advice. Deposit-amount limits, licensing requirements, permit rules, and lien/contract law vary by trade and by state or local jurisdiction; consult a licensed professional or your local licensing board before relying on this Service for a real contract dispute or a licensing question.
3. General trades guidance, not a substitute for the actual contract. Payment-schedule patterns and red-flag guidance describe common practices; they are not a review of, or opinion on, any specific real quote or contract.
4. Estimates, not guarantees. Nothing in the Service guarantees the accuracy of a real quote, that a contractor or client will honor a computed schedule, or that following the red-flags checklist will prevent a bad outcome.
5. Acceptable use. Automated use within the published rate limits is welcome.
6. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
7. Data. Our Privacy Policy describes what we process. In short: your query is answered on our server and nothing is stored.
8. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
9. Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any financial or legal consequence arising from use of or reliance on the Service. Our total liability is limited to US $100.
10. Governing law. California law; venue in San Mateo County, California.
