What should I work through before I launch?
Start with the decisions that shape cost, risk, and operations: Navigate the licensing ladder: Understand the apprentice-journeyman-master pathway, how PSI Exams and state boards qualify your contracting entity, and why the qualifying individual clause is a structural risk that needs a contractual solution before you hire your first technician. Build your insurance and bonding stack: Structure general liability, workers' compensation at plumbing's high-risk classification rates, commercial auto, inland marine tool coverage, and contractor E&O - and understand what a coverage lapse costs you at license renewal time. Price jobs so they profit: Calculate your fully-burdened labor rate, set flat-rate, time-and-materials, and lump-sum prices correctly, apply appropriate material markups, and charge after-hours rates that actually cover your costs.
Do the companion tools replace local professional advice?
No. The calculators, worksheets, and checklists help organize planning decisions, but local rules, taxes, licensing, insurance, contracts, and technical standards must be verified with the responsible agencies and qualified professionals.
