Pool Cleaning & Maintenance input evidence register
43 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 · Two used compact service vehicles and initial upfit · Cleaning poles, vacuums, test kits and route tools · Chemical storage, spill control, PPE and opening inventory · Licenses, training, insurance and deposits · Route software, website, phones and launch materials · Working-capital reserve
Authored two-route opening allocation. Current test-kit and software prices plus licensing and chemical-safety sources inform category selection but do not verify vehicle, storage, insurance or reserve amounts. The low and high cases describe different launch formats.
- Model assumption
Applies to: Revenue (Years 1–5)
Authored active-account path. Year three is 140 accounts × $210 per month × 12. Vendor menus bracket recurring service formats but do not establish this route's fee, account count or retention.
- Model assumption
Applies to: Chemicals, route fuel, card fees and service supplies (Years 1–5)
Authored 18% sales-linked share for chemicals, route fuel, payment fees and service supplies. Replace it with purchases, miles, callbacks and fees by cohort.
- Model assumption
Applies to: Owner-manager and pool 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: Vehicle, storage, insurance, software, marketing and other overhead (Years 1–5)
Authored annual vehicle, storage, insurance, software, marketing and administration schedule. It is not a local quote or cash-flow forecast.
- Model assumption
Applies to: Retained weekly service-visit equivalent (base scenario) · Retained weekly service-visit equivalent (lower sensitivity) · Retained weekly service-visit equivalent (upper sensitivity) · Completed routine visits per field day across both routes (base scenario) · Completed routine visits per field day across both routes (lower sensitivity) · Completed routine visits per field day across both routes (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 operating bridge. $210 monthly × 12 ÷ 52 = $48.461538 per weekly visit equivalent; 28 visits/day × 5 days × 52 weeks reconciles to about $352,800. Contribution, density and ramp remain assumptions.
