The problem this solves

Most plumbing businesses lose money the same three ways: undercharging drain calls that drag on, no flat-rate system so every estimate is a guess, and service agreements that never get signed.

What's in the Price Book

Pre-priced jobs with markup logic you adjust to your market.

What makes this kit Plumber-specific

Every kit has the same core — these are the pieces built only for plumber contractors.

Drain Call Pricing System
Flat rates for 7 drain scenarios — stop losing money when a 45-minute job turns into 3 hours.
Water Heater Install Sheet
Pre-filled checklist covering permits, code compliance, disposal, and closeout so every install is billable top to bottom.
Maintenance Agreement Template
Annual plumbing inspection contract with renewal clause — turns one-time customers into recurring revenue.
Backflow & Camera Report Forms
Two-page field forms for CCTV inspections and backflow certification — ready to sign on-site.

Free: The Tradesman's Toolbox App

Web app with Plumber calculators, job cost estimator, markup calculator, and more — no account needed. Use it alongside the kit or on its own.

Common questions

Is this for residential or commercial plumbing?
Primarily residential service — drain, water heater, fixture, leak. The pricing methodology and business templates work for commercial too, but the price book examples are residential-focused.
Does it cover A/C or gas work?
No. This kit is plumbing-only. HVAC and gas line pricing is covered in the HVAC kit.
How current is the pricing data?
The price book gives you the markup formula and labor unit costs — you adjust the material costs for your local market. The formula doesn't go stale, local prices do.
I already have an invoice template. Do I still need this?
The kit includes 12 templates total. The value is in the field manual (20 chapters on running the business) and the price book (stop estimating every job from scratch).
Can I share this with my office manager or employees?
Yes. One purchase, unlimited internal use. You can't resell it.
