Representative cleaning contract scenario

Repräsentatives Szenario — modellierte Exposition, kein verifiziertes Kundenergebnis.

Problem

A cleaning contractor quotes square meters and visit frequency but under-models supplies, travel between sites, and non-billable setup — monthly contracts turn thin after the first audit.

Eingabesatz

  • Service area 9,500 m², frequency 5× weekly
  • Hourly rate $26, supplies $380/mo, travel $210/mo
  • Target margin 15%

Versteckter Verlust

Supplies, travel, and setup minutes missing from the client proposal — roughly $590/mo in this illustrative overhead stack.

Overhead & supply leak

Berechnungsergebnis

Client budget $5,100/mo vs modeled safe monthly floor ~$5,920/mo — about 14% under the margin target before overhead (representative model).

Monthly labor from area × frequency × productivity, plus supplies and travel; minimum safe monthly bid at target margin.

Empfohlene Maßnahme

Adjust monthly bid or reduce scope if the client cap sits below the modeled safe floor.

Geschätzte Auswirkung: Illustrative monthly margin pressure range — not a verified account result.

Methodik-Hinweis

Browser-side deterministic bid model with user productivity assumptions — decision-support only, not a contractual quote.

  • Productivity and visit frequency as entered
  • Travel aggregated per route, not per site detail
  • Representative scenario — modeled exposure, not a verified customer outcome.
