## What is WashMargin?

WashMargin brings estimating, field preparation, and completed-job costing into one private workspace for pressure-washing and exterior-cleaning operators.

Build a scope from your own service presets, quantities, minimums, production rates, and product costs. Compare unit-rate pricing with a whole-job cost floor that includes setup, teardown, crew time, travel, equipment, overhead, contingency, card fees, and your target margin. Stress-test the estimate against extra labor, chemical overrun, a return trip, or a customer discount before saving it.

Move estimates through a real pipeline from draft to paid. Scheduled work includes a production clock, staged crew checklist, site notes, and optional before-and-after photos you select. After closeout, record actual time, costs, callback time, payment fees, and collected revenue. WashMargin then compares the plan with what the job really earned.

KEY FEATURES

- Draft, sent, accepted, scheduled, completed, paid, and declined pipeline stages
- Editable service presets, unit rates, minimum charges, and production rates
- Whole-job labor, travel, supply, equipment, overhead, and contingency model
- Unit-rate, cost-floor, and higher-guardrail pricing choices
- Discount, tax, payment-fee, and target-margin controls
- Four what-if risk scenarios for every estimate
- Scheduled-job production clock and staged field checklist
- User-selected before-and-after job photos stored locally
- Actual revenue, cost, profit, margin, and revenue-per-hour records
- Profit and time-calibration charts by job and surface
- Local recommendations for follow-up, margin, and production assumptions
- Shareable estimate text and on-device PDF creation
- Portable JSON workspace backup and restore
- No account, ads, analytics, tracking, subscription, or developer-operated server

WashMargin does not publish market rates, process payments, contact customers, replace safety training, or provide legal, tax, accounting, or site-specific compliance advice. Results depend on the scope, costs, rates, and assumptions you enter.
