Verify identity and authority
Match the proposal’s legal business name and contractor licence to official records. Confirm the salesperson is authorized to represent the contracting entity.
Compare evidence, not badges
Review licence status, scope, equipment, warranties, recent project references, complaint handling, subcontractor use, payment milestones, and who owns the interconnection process.
Watch for pressure
Pause when a quote depends on same-day signing, guaranteed utility increases, vague tax-credit promises, missing equipment models, or an unexplained difference between cash and financed price.
