Painting Business input evidence register
44 financial inputs with their assumptions, calculation bases and cited sources.
Read the supported claim, observation period, geography and units together. A source access date records when it was consulted. A model assumption identifies a selected amount or target; a calculated result follows from those inputs and does not establish observed demand or a quoted opening budget.

These notes explain the opening budget, annual forecast and calculator assumptions. Linked sources provide the support described in each note; they do not necessarily confirm the selected amounts. Check scenario assumptions against local quotes and operating records.
- Model assumption
Applies to: Total opening budget · Lower opening budget · Upper opening budget · Used cargo van, trailer allowance and storage upfit · Spray, preparation, ladder and access equipment · Safety, containment and site-protection equipment · Opening coatings, materials and consumables · Licenses, bonds, insurance, training and deposits · Software, website, marketing and administration · Working-capital reserve
Authored one-crew opening allocation. Current sprayer, new-van, startup-cost and contractor-classification sources inform categories but do not verify a used vehicle, full equipment set, compliance cost or reserve.
- Model assumption
Applies to: Revenue (Years 1–5)
Authored crew-day path. Year three is $2,200 × 1 crew-day equivalent × 5 days × 50 weeks. Industry and occupation sources establish scope context but not local price, volume or backlog.
- Model assumption
Applies to: Coatings, sundries, payment fees and other sales-linked costs (Years 1–5)
Authored 40% sales-linked pool for coatings, sundries, payment fees and other variable leakage. Replace it with estimates, purchase invoices, waste, credits, rework and callbacks.
- Model assumption
Applies to: Paid owner-estimator and painting crew payroll (Years 1–5)
Authored paid owner-estimator and two-painter schedule with employer-cost allowance. National occupation pay and federal payroll-tax components are context only.
- Model assumption
Applies to: Vehicle, insurance, equipment, software, marketing and other overhead (Years 1–5)
Authored vehicle, insurance, equipment, software, marketing and administration schedule. It is not a local quote or dated cash forecast.
- Model assumption
Applies to: Retained sale per completed crew-day equivalent (base scenario) · Retained sale per completed crew-day equivalent (lower sensitivity) · Retained sale per completed crew-day equivalent (upper sensitivity) · Completed crew-day equivalents per field day (base scenario) · Completed crew-day equivalents per field day (lower sensitivity) · Completed crew-day equivalents per field day (upper sensitivity) · Trading days per week (base scenario) · Trading days per week (lower sensitivity) · Trading days per week (upper sensitivity) · Monthly fixed operating costs · Contribution margin · Opening sales as a share of mature volume · Monthly increase toward mature volume · Forecast horizon (months)
Authored crew-day break-even bridge. The $2,200 value, one crew-day, 60% contribution, fixed cost and ramp must be reconciled to project estimates, paid hours, materials, access, rework and collection.
