Who the product is for
The initial tools are designed around businesses with roughly 2–20 people in HVAC, plumbing, electrical, remodeling, painting, landscaping, roofing, handyman services, cleaning, and concrete. The underlying question is shared: what must a job sell for after direct labor, labor burden, overhead, materials, subcontractors, waste, callbacks, and desired profit?
Why the tools connect
A markup calculator alone cannot reveal an incomplete labor rate. A labor rate alone cannot recover office payroll or insurance. A planned price alone cannot show where an actual job leaked margin. TradeQuote Lab connects those decisions in a deliberate sequence: direct cost, burdened labor, overhead and break-even, selling price, change-order protection, then bid-to-actual review.

The product promise
- Core calculators remain free and require no account or email.
- Core calculations run locally in the browser without a paid API.
- Saved profiles and scenarios stay local unless the user exports them.
- Every result exposes its formula, substitutions, assumptions, exclusions, and version.
- Raw financial inputs do not enter analytics or error reports.
- Affiliate relationships do not influence formulas, diagnostics, or result ranking.
What TradeQuote Lab is not
It is not a CRM, invoice system, customer portal, contract-signing service, dispatcher, payment or payroll processor, bookkeeping ledger, market-price oracle, live tax engine, or supplier-price feed. The product does not invent “average” local prices without defensible source data.
How accuracy is maintained
Formula functions are deterministic and decimal-safe. Versioned specifications define units, rounding, and exclusions. Unit, boundary, property-oriented, golden, accessibility, SEO, indexability, and browser journey tests support each release. Human review remains required for factual and formula quality.
Read the methodology, inspect the formula history, or use the public correction path when something needs attention.
How the free product can be supported
A clearly labeled, contextually relevant partner resource may appear below a completed result. It never gates the calculation or changes the answer. The affiliate disclosure documents the placement and independence rules.
