# ServiceRig > Field-service management software for **plumbing companies**, built and tested by a working Texas master plumber (TSBPE M-45353). Dispatch, CRM, estimates, invoicing, payments, an AI receptionist, and a 457-item plumbing pricebook — every feature on every plan. Priced by slots, not seats. ServiceRig is run from Commerce, Texas. Phone: (903) 401-6639. The product is plumbing-only today; HVAC & Electrical are planned for 2027. ## Pricing (canonical) Slot-based, not per-seat. Every slot gets the full platform; permissions decide who does what, not the bill. A card is kept on file on every plan (Free has no monthly charge); fees settle daily and itemized. The platform fee is charged **on top of** standard card processing (~2.9%), on payments you actually process through ServiceRig — record cash/checks free. - **Free Forever** — $0/mo · 5 slots · **3.5%** platform fee · 150 AI estimates/mo · 60 AI-receptionist min/mo - **Business Essentials** — $1,100/mo (or $11,000/yr, two months free) · 10 slots (+$140/extra) · **1%** platform fee · 1,000 AI estimates/mo · 120 receptionist min/mo - **Max Leverage** — $2,700/mo (or $27,000/yr, two months free) · 15 slots (+$50/extra) · **0.5%** platform fee · unlimited AI estimates · 180 receptionist min/mo - **The Founding 100** — first 100 plumbing companies, **annual billing only**, founding rate locked for life (Wave 1: 50% off subscription for life; Waves 2–3: 50% for 12 months then 25% for life).
