What should a plumbing invoice include?

Your business name, contact details, and license number; the customer and service address; an invoice number and date; any service call fee; labor and parts on separate lines; permits or disposal fees; tax where it applies; the total; your warranty; and payment terms.

Should plumbers charge sales tax on an invoice?

It depends on your state. Some states tax parts and materials but not labor, some tax both, and some tax neither. Enter your rate in the tax field if it applies, and check with your state revenue department or accountant for how plumbing services are taxed where you work.

Is this invoice template really free?

Yes. There is no sign-up and nothing to install. The generator runs entirely in your browser. The details you type are not sent to or saved on our servers. Fill it in, then download or print it as many times as you like.

How do I save the invoice as a PDF?

Click “Download / print PDF”. Your browser’s print window opens with only the invoice on the page; choose “Save as PDF” (or “Microsoft Print to PDF”) as the destination to save a file you can email or text to your customer.

Can ChatGPT or another AI assistant fill in this invoice for me?

Yes. Tell the assistant your business, customer, and line items and ask it to make an invoice with redbudway.com. It can build a link to this page with the details filled in (the format is described on the page); you open the link, check and edit the invoice, and download it as a PDF. The details sit after the # in the link, which browsers do not send to our servers.

Can my customer pay the invoice by card?

A PDF invoice can only ask for payment: your customer still has to mail a check or find another way to pay. With a free Redbud Way account you can send the invoice with a card pay link instead, or send a quote that collects a deposit first, and the money is paid out to your bank about two business days after each payment. Redbud Way charges a 0% platform fee. Stripe’s standard fees apply, billed to your own Stripe account: 2.9% + 30¢ per card payment plus 0.4% Stripe Invoicing on an invoice or quote, so a $300 invoice costs $10.20. The full fee table is at redbudway.com/pricing#fees.

Why Redbud Way is free

What to include on a plumbing invoice

License number. Most states license plumbers; putting your license number on the invoice builds trust and is required on paperwork in some states.
Service address and problem. Where the work was done and a short description of the issue you were called out for.
Service call or trip fee. If you charge a dispatch or diagnostic fee, give it its own line.
Labor and parts, separately. Break out labor from parts like valves, fittings, and fixtures, with quantities and prices.
Permits and disposal. Water heater and repipe jobs often carry permit and haul-away costs, so list them.
Warranty and terms. Your labor warranty, any manufacturer warranty on parts, and when payment is due.

Tips for getting plumbing invoices paid faster

Write what you found and what you fixed in the notes. A clear “replaced failed pressure-relief valve” line beats “plumbing repair”.
Emergency and after-hours work should show the premium as its own line so the customer sees why the price differs.
On bigger installs like a water heater or repipe, collect a deposit when the customer approves the quote to cover equipment.
Invoice before you leave the driveway. Payment due on receipt is standard for service plumbing.

Pricing the job first? Use the job cost estimator or the markup calculator. See also Redbud Way for plumbers.
