What to Put on Invoices for Plumbers
Plumbing invoices are frequently pulled up years later during a property sale or an insurance claim, so specificity pays off.
- Property address — Not just the billing address - often a landlord or agent is paying.
- Problem reported — What the customer called about.
- Diagnosis — What you actually found.
- Work performed — The repair or installation, described plainly.
- Parts and fixtures — Itemized, with make and model for anything installed.
- Labor — Hours or flat rate, with any emergency premium named separately.
- Call-out fee — Shown, and shown as credited if you credit it.
- Permit — Cost and permit number where one was pulled.
- Warranty on labor — Your guarantee period, in writing.
Frequently Asked Questions
What is a reasonable call-out or service fee?
Enough to cover your drive time and the slot, and it should be quoted on the phone before you roll. Whether you credit it against the work is your call, but the customer must know about it before you arrive - surprise call-out fees are the most common source of plumbing invoice disputes.
Should I charge emergency rates for nights and weekends?
Yes, and state the multiplier clearly when the call comes in. Someone with water coming through a ceiling at 2am is not price shopping, but they will absolutely be angry the next morning if the premium appears for the first time on the invoice.
How much can I mark up parts?
Markup on parts is normal and legitimate - you carry the stock, the sourcing, and the warranty. What causes trouble is an invoice showing a large undifferentiated "materials" number. Itemizing each part at your price is both more defensible and less likely to be queried.
When do permits need to appear on the invoice?
Any time one was pulled - water heater replacements, repipes, sewer laterals, gas line work. Show the permit cost and the permit number. It proves the work was done legally, and it is the first thing asked for when the property is sold or an insurer gets involved.
How do I invoice a job that turned out much bigger than quoted?
Stop and re-quote before doing the extra work, not after. A wall opened up to reveal a failed section of main is a new job, and it should be a documented change to the price with the customer's agreement. Photos of what you found, attached to the invoice, end almost every argument before it starts.
