The Cost Engine is free permanently and is not a trial. It covers the operating calendar, overhead, trucks, equipment, labor with payroll burden, administrative time, and the service catalog priced from those inputs — plus the profit dashboard, scheduling and calendar, and customer and lead management.
Free exists because an operator discovering his own pricing gap is more persuasive than being told about one. Most operators have never seen their overhead expressed as a dollar figure per working hour.
Quoting with a live margin verdict, three-tier Good/Better/Best proposals, the AI-generated microsite, Stripe booking and deposits, invoicing, the cold outreach tracker, Offer Lab for testing offers against acquisition cost and lifetime value, the AI Copilot, and the automation hub.
An add-on at $199, $299, or $499 per month. Sarah answers the phone when the operator cannot, greets callers with the business name, qualifies the lead, and files it. Higher tiers add calendar booking, custom scripts, escalation to a human, and voice cloning.
Operators connect their own Stripe account and are the merchant of record — customer payments land in the operator's account directly, not in Plumline's. Standard Stripe processing fees apply and are set by Stripe.
