Representative cleaning contract scenario
Scénario représentatif — exposition modélisée, pas un résultat client vérifié.
Problème
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.
Jeu d'entrées
- Service area 9,500 m², frequency 5× weekly
- Hourly rate $26, supplies $380/mo, travel $210/mo
- Target margin 15%
Perte cachée
Supplies, travel, and setup minutes missing from the client proposal — roughly $590/mo in this illustrative overhead stack.
Overhead & supply leak
Résultat du calcul
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.
Action suggérée
Adjust monthly bid or reduce scope if the client cap sits below the modeled safe floor.
Impact estimé: Illustrative monthly margin pressure range — not a verified account result.
Note méthodologique
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.
