A practical guide to billing a plumbing service call from arrival to paid, written for solo plumbers and small crews. It breaks the service call into five stages: charging a diagnostic fee every time, presenting a flat-rate price the customer will approve, doing and photographing the work, building a complete itemized invoice on site, and collecting card payment before leaving the driveway.
Includes a full worked example on a Saturday water heater replacement with real 2026 numbers, market price ranges for common plumbing jobs, and why a field app that saves prices, carries a pay link, and timestamps photos beats a paper pad once you have repeat customers..
