How to write a plumber invoice

What goes on a plumber invoice

Six things, in the order they belong on the page. The invoice generator opens a plumber document with the lines already in place, so most of this is checking rather than typing.

1. Charge the call-out as its own line. It covers travel, diagnosis and the first hour. Folded into labor it looks like an inflated hourly rate.
2. Show the hours with the count. Two hours at your rate reads as two hours. One figure for the visit invites the question about how long you were there.
3. Price parts separately from labor. When a supplier price moves it is a rate edit rather than an argument about what your time is worth.
4. Name the part you fitted. Which valve, which unit, which model. It is what a customer needs for a warranty claim and what you need if it fails.
5. Put waste removal on the invoice. Taking away the old cylinder and the packaging is a cost. Unnamed, it is a free service you provide every job.
6. State the emergency or out-of-hours rate. A different rate for nights and weekends belongs on the document before the night you use it.

The lines a plumber invoice usually carries

The generator opens with these lines when you pick Plumber. The figures are placeholders to type over, not a going rate.

Add, rename, reorder or delete any line, and set tax per line where it applies. Priced as they open, that comes to $405 before tax.

How to write a plumbing invoice, step by step

1. Put the property and any works order first. Open the plumber invoice and enter the job address and, on landlord or agent work, the works order number they gave you. Without it, an agent's invoice sits in a pile.
2. Enter the call-out and the time on site. The call-out and first hour is one line. Extra hours go on as their own line with the count, taken from your arrival and finish times.
3. Name the parts you fitted. The make and model of the valve, heater or pump, not just parts. That line is the customer's warranty record and yours.
4. Add waste removal. Taking the old heater and the packaging away costs you a trip and a fee. Put it on the invoice so it is not a service you give away every job.
5. Mark the rate that applied, then send. If it was a night or weekend call, say that the out-of-hours rate applied. Set 14 days, add a payment link and send it before you leave the property.

Plumbing invoice example, filled in

An emergency call to a leaking bathroom basin, with two extra hours, a replacement mixer and the old fittings taken away. Parts and labor are separate lines, and the note names what was fitted, so the customer can check both and keep a warranty record.

Subtotal $405, tax $40.50, total $445.50. The call-out and first hour at $95 is kept apart from the two extra hours at $65, so the hourly rate the customer was quoted is the rate they see. The note naming the parts fitted is the warranty record for both of you.

The call-out fee, and why it belongs on its own line

Almost every plumbing dispute starts with a customer comparing an hourly rate they were told to a total they were not expecting. The gap is usually the call-out.

Bill it as a named line covering travel, diagnosis and the first hour. Stated separately it is a normal trade charge that customers understand; buried inside labor it makes your hourly rate look like it doubled on the way to their house.

If the job then runs long, additional hours go on as their own line with the count showing. Two lines a customer can add up beat one number they have to accept.

Parts, markup and the receipt the customer asks to see

Marking up parts is standard trade practice and customers largely accept it, right up until they feel it has been hidden from them.

Put parts on their own line at your selling price and name what was installed. You are not obliged to publish your buying price, but you should never be in a position where a customer discovers the margin by accident rather than understanding it as normal.

Where a customer supplies their own parts, say on the invoice that they were fitted at the same labor rate and that the part carries no warranty from you. That sentence prevents a return visit being free.

Landlords, property managers and the invoice that has to reach an office

Work for a property manager is not work for a homeowner. The person watching you is a tenant who is not paying, and the payer never sees the job.

That invoice needs the property address as the reference, the job or works order number the agent gave you, and terms in days rather than on receipt. An agent processing forty invoices a month cannot match "boiler repair" to anything.

Where a tenant reports a fault and an agent authorizes it, get the authorization reference on the invoice. It is a common reason a property manager invoice sits unpaid.

Hourly, fixed price or per unit: how plumbers price the work

Plumbing splits cleanly. Reactive work is sold by the hour because nobody can price a leak they have not seen, and planned work is sold as a fixed price because a customer replacing a bathroom wants a number, not a meter running. Trying to use one model for both is what produces the invoice a customer argues with.

The practical rule is to quote fixed only for work you can survey, and to put the exclusions on the quote in the same breath as the price. Everything else goes out at call-out plus hours, with the hours shown on the invoice so the customer is adding up a count rather than accepting a figure.

Working out what to charge

Plumbing prices depend on your area, the hour of the call and the parts you carry, so a rate from a web page cannot be yours. The cost estimator builds a price for planned work from your own materials and labor, and the markup calculator sets the margin on parts.

Getting paid once it is sent

Reactive work is best paid before you leave, by the payment link on the invoice; planned installs take a deposit for the heater or the suite before you order it. If the due date passes, the late fee calculator works out what your terms allow and the due date calculator sets the new date.

Five dates decide whether a plumber gets paid on time, and four of them are set before the work starts.

Mistakes that cost plumbers money

• Call-out folded into labor. Your hourly rate looks like it doubled between the phone call and the invoice.
• Parts unnamed. No warranty trail for the customer and no record for you when it fails.
• Waste disposal unbilled. A cost you absorb on every single job.
• No out-of-hours rate. It gets decided at midnight, and not in your favor.
• No property or works order reference on agent work. It will not be queried, it will just wait.
