Everything a plumber needs to price a job, get paid, and win more work — free.
Pipe-volume math, invoices, estimates, contracts, and the pricing calculators — all in one place, built specifically for plumbing contractors.
Price the job
Get the number right before you send it.
A water-heater swap and a re-pipe don’t price the same way. Start with the pipe-volume calc, build the estimate off it, and check your markup before it goes out.
Pipe Volume Calculator
Figure water volume and fill time by pipe diameter and length — for flushes, re-pipes, and system sizing.
Plumbing Estimate Template
Line-item estimate built around a real water-heater replacement job, ready to send.
Markup vs. Margin Calculator
Know the difference before you quote — the two numbers are never the same.
Plumbing Code Quick-Reference
Plain-English, searchable index of 221 UPC & IPC rules — DWV, venting, traps, water supply & more.
Most plumbers undercharge for one of two reasons: they price off gut feel instead of the actual pipe run, or they forget to build overhead and their own labor burden into the number. Fix both and the same jobs get more profitable without raising a single rate.
Bill & get paid
Send an invoice that gets paid on time.
An itemized plumbing invoice, a rate that actually covers your overhead, and the recovery math to check it.
Win the work / paperwork
Look like the professional bid, not the guy with a van.
A written scope, a signed contract, and a proposal that reads like a real business — the paperwork that wins the job before price even comes up.
Run the business
Know your numbers, not just your prices.
Labor burden and break-even — the two numbers that tell you if the business itself is actually profitable.
