What to Include on a Plumbing Invoice

Every invoice needs the same commercial basics. What separates a plumbing invoice is the job detail that proves what was done — the part generic templates leave out.

Standard invoice details

  • Your business name, address, phone, and email
  • The client's name, billing address, and contact
  • A unique invoice number and the invoice date
  • Payment due date and payment terms
  • Itemized description, quantity, unit, and rate per line
  • Subtotal, tax, any discount or deposit, and the balance due

Plumbing-specific detail

  • Permit Number
  • Fixture Type
  • Water Heater Serial
  • Inspection Date
  • Shutoff Location

In ServiceInvoicing these become a reusable schema, so they appear on every new invoice automatically.

Stop Rewriting the Same Details on Every Plumbing Invoice

A printed template is fine for a one-off. But if you are invoicing the same customers month after month, you end up copying the same business details, the same addresses, and the same plumbing job fields by hand every time — with no record of who has paid. A free ServiceInvoicing account saves all of it once and remembers it for you.

With the printed template

  • Rewrite your business details on every single invoice
  • Retype the client's name, address, and phone every time
  • Keep a paper copy filed somewhere, or lose the record
  • Add up line items, tax, and the balance by hand
  • Flip through a folder to find out who has not paid

With a free account

  • Your business details, logo, and default tax rate save once
  • Clients save to an address book — pick them from a list next time
  • Every invoice is stored and downloadable as a PDF whenever you need it
  • Subtotal, tax, discounts, and deposits calculate as you type
  • Mark invoices Draft, Pending, Paid, or Overdue and filter by client or status to see what you are owed

How it works

  1. 1

    Create a free account

    Sign in with your email or a Google account. No credit card, and the free plan includes unlimited invoices.

  2. 2

    Add your clients once

    Save each client's business name, contact, address, phone, and email. On every future invoice you pick them from a list instead of writing it out again.

  3. 3

    Save your plumbing fields as a schema

    The 5 job fields on this template — permit number, fixture type, water heater serial and the rest — become a reusable schema. Set it as your default and every new invoice opens with them ready to fill in.

  4. 4

    Come back any time

    Your clients, schemas, and full invoice history are waiting when you next sign in. Finish a saved draft, filter past invoices by client or status, or pull a revenue report at tax time.

As your plumbing business grows

Paid plans add employee access so your crew can invoice under your account, a client portal where customers sign in to view invoices and sign contracts, time entries for hourly work, and reports you can export to CSV for your bookkeeper. Plans run from $9 to $39 a month, and you can start on the free plan and upgrade whenever you outgrow it.

Plumbing Invoice Template FAQ

What should a plumbing invoice include?

Beyond the standard details — your business information, the client's details, a unique invoice number, dates, itemized lines, and the balance due — a plumbing invoice should carry the job detail your customers and any inspector or adjuster expect: permit number, fixture type, water heater serial, inspection date, shutoff location. Recording those on the invoice itself keeps the paperwork with the job.

Is this plumbing invoice template really free?

Yes. Print the blank template or save it as a PDF from your browser with no sign-up. If you would rather stop filling forms in by hand, ServiceInvoicing's free plan covers 2 active clients and unlimited invoices with no credit card required.

How do I turn this into an invoice I can send?

Print the blank form and complete it by hand, or create a free account and build the same invoice on screen. In the app you can save the plumbing job fields as a reusable schema, so every new invoice starts with 5 trade-specific fields already in place.

Should I charge tax on a plumbing invoice?

That depends on your state or locality and on whether you are billing labor, materials, or both — rules differ widely, so check with your accountant or your state's revenue department. The template leaves tax as its own line so you can apply whatever rate applies to you.

Can I save my client details instead of rewriting them every time?

Not on the printed form, but that is exactly what a free account does. Each client's business name, contact, address, phone, and email save to an address book, and you select them from a list on any future invoice. Your own business details, logo, default tax rate, and plumbing job fields save once in settings too.

Can I start an invoice now and finish it later?

Yes, with an account. Save an invoice as a draft and it waits for you until you sign back in — useful when you are pricing a job on site and want to finish the paperwork at the end of the day. Your whole invoice history stays available too, filterable by client or by status, so you can look up what you charged a customer last time before quoting the next job.
