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

These are the lines the generator opens with when you pick Plumber. The figures are a starting point to type over rather than a going rate: this site runs no pricing survey, and the number on your invoice should be the one you charge.

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.

A worked plumber invoice, filled in

This is the same job as the table above, written out the way it would leave your phone. Every figure on it is a starting point rather than a going rate, and the tax line is shown at ten per cent purely so the arithmetic is visible: set your own rate, or none, per line.

Subtotal $405, tax $40.50, total $445.50. The parts worth copying are the structure rather than the numbers: the job reference next to the client, every line separately priced with its count showing, the tax on its own line, and terms that name a number of days instead of saying on receipt.

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 authorises it, get the authorisation reference on the invoice. It is the single most 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

This guide is about what goes on the document, not what the number should be, and nobody should hand you a rate for your own market. What the site can do is the arithmetic: the freelance rate calculator works back from what you need to earn, the service price calculator prices a service against your costs, and the profit margin calculator checks what is left once the job is done.

Writing it on your phone, in five steps

Most plumbers write the invoice standing next to the work rather than at a desk a week later, and the week later version is the one that gets details wrong. The generator is built for the first case.

1. Open it with your trade already chosen. The plumber invoice loads with emergency call-out and first hour and the rest of the lines already on the page.
2. Put the client and the job reference in first. It is the part you will not remember accurately in three days, and on agent, landlord or contractor work it is the reason the invoice gets paid at all.
3. Edit the lines rather than starting from empty. Change the quantities and the rates, delete what you did not do, add what you did. Keeping the descriptions means the wording stays consistent from one job to the next.
4. Set the terms to 14 days and add a payment link. A due date that is an actual date gets chased. A link and a QR code means it can be settled before you have packed up.
5. Send it before you leave. The clock on your terms starts when the invoice arrives, not when the work finished, so every day it sits unsent is a day added to getting paid.

Getting paid once it is sent

Put a due date and your terms on the document, because an invoice without them is hard to chase. Add a payment link and a QR so settling up is a tap rather than a transfer somebody has to set up. When part of it lands, the receipt maker records it as a part payment and prints the balance still due. If the due date passes, the late fee calculator works out what your own terms allow and writes the chasing letter to go with it.

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 favour.
• No property or works order reference on agent work. It will not be queried, it will just wait.
