Minimum credible offer

A narrowly defined service that fits verified licensing, technical capability, insurance, tools, and safe operating procedures.

Part-time fit: Difficult
Customer response expectations, technical work, permits, and job overruns make casual scheduling difficult.
Solo-start fit: Team Dependent
Solo operation depends heavily on verified licensing, technical capability, insurance, tools, vehicle readiness, and safe service scope.
Ongoing cost signal: High Or Working Capital Sensitive
Vehicle, tools, parts, insurance, training, callbacks, and response capacity require continuing investment.

Must be ready

  • Prepare tools, vehicle, safety, estimating, documentation, and referral procedures

Can usually wait
