Handyman Service 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 · Launch van plus reserved second used van and storage upfit · Hand tools, power tools, ladders and dust control · Safety equipment, jobsite protection and storage · Opening materials, fasteners and consumables · Licenses, bonds, insurance, training and deposits · Software, website, phones, marketing and administration · Working-capital reserve
Authored two-worker opening allocation. Current tool, ladder, new-van and licensing sources inform category selection but do not verify used vans, full inventory or reserve.
- Model assumption
Applies to: Revenue (Years 1–5)
Authored completed-job path. Year three is 3 jobs × $450 × 5 days × 50 weeks. Census classification and occupational duties establish a service scope but do not establish price, volume, route capacity or demand.
- Model assumption
Applies to: Job materials, card fees, route fuel and consumables (Years 1–5)
Authored 22% sales-linked pool for job materials, payment fees, route fuel and consumables. Replace it with job invoices, miles, waste, discounts and callbacks.
- Model assumption
Applies to: Owner-manager and handyman technician payroll (Years 1–5)
Authored paid working-owner and technician schedule with employer-cost allowance. National occupation pay and federal payroll-tax components are context only.
- Model assumption
Applies to: Vehicles, insurance, tools, software, marketing and other overhead (Years 1–5)
Authored vehicle, insurance, tool, software, marketing and administration schedule. It is not a local quote or cash forecast.
- Model assumption
Applies to: Retained sale per completed repair job (base scenario) · Retained sale per completed repair job (lower sensitivity) · Retained sale per completed repair job (upper sensitivity) · Completed jobs per field day across both workers (base scenario) · Completed jobs per field day across both workers (lower sensitivity) · Completed jobs per field day across both workers (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 completed-job bridge for break-even. The $450 ticket, three jobs, 78% contribution, fixed cost and ramp must be reconciled to paid hours, route time and service mix.
