Summary

  • An invoice creates a formal request for payment
  • It also builds trust by showing clients exactly what they’re paying for
  • An effective plumbing invoice helps build your professional reputation

Invoices can help establish trust through billing transparency. They make cash flow tracking simpler, and they can even save you from having to chase down late payments. In this article, we’ll look at how to create an effective plumbing invoice.

What to Include on the Invoice

If you’re creating a plumbing invoice template for the first time, make sure you at least include the following:

  • Your company name and information
  • The client name and contact information
  • The unique invoice number and the date
  • An itemized list of services and their prices
  • The total due and the due date

Your invoice should also state your payment terms, which include the amount of time the client has to pay, the payment methods you accept and any late fees or early payment discounts.

Types of Plumbing Invoices to Keep

For many plumbers, no two days on the job are exactly alike. Instead of just creating one standard plumbing invoice, it’s a good idea to have three types:

  • Repair Invoice: Documents the issue you found, what you did to repair it and the total cost
  • Service Invoice: Used for routine maintenance and service calls
  • Installation Invoice: Documents the price of the unit installed, haul-away costs and price of labor

Specialized invoices like these help clients understand exactly what they’re being billed for.

Estimating Labor and Parts

When setting pricing for labor and parts, you should first understand your fully burdened labor rate, which includes employee wages, taxes and insurance. Many plumbers add a 10% to 20% markup to ensure each job is profitable.

Setting Payment Terms

The terms you set are up to you. Many plumbers make payment due upon receipt for smaller jobs and use net 15 or net 30 payment terms for larger jobs.

Your payment terms are an important part of your invoice. You should also outline them when you draft a plumbing service agreement. If a customer fails to pay and you need to send a demand letter or file a lawsuit, having proof that they agreed to your terms can be incredibly helpful.

When to Send the Invoice

It’s generally a good idea to send an invoice immediately after work is done. However, for very large projects, you might send an invoice for a deposit before work begins and then invoice for the remaining balance once work is complete.

Tips to Get Paid Faster

Here are a few tips to help you receive payment faster:

  • Send your invoice while on site.
  • Offer early payment discounts.
  • Set late fees.
  • Require deposits for larger jobs.
  • Use invoicing software to send payment reminders.

These tips may not only benefit your business. If you draft a plumbing subcontractor agreement, securing payment faster means your subcontractor gets paid quickly, too.

Frequently Asked Questions

Everything you need to know about our plumbing invoice template

A plumbing invoice is a billing document sent by a plumber or plumbing company to a customer requesting payment for completed plumbing work. It includes the plumber's business details and license number, the customer's information, the service address where work was performed, an itemized list of labor, parts, and fees with quantities and rates, and payment terms. A professional plumbing invoice serves as a legal record of the work performed and the amount owed — it is a billing document, not a contract. It works like any other invoice: a formal request for payment and a record of the sale, not a contract.

A complete plumbing invoice should include: your business name, license number, license type, and insurance information; the customer's name and billing address; the service address (job site); the service date and type of work performed; itemized line items for labor, parts, fixtures, permits, and fees; parts markup if applicable; any emergency or after-hours surcharges; warranty terms; payment terms and due date; and your tax ID for commercial customers. This invoice includes all of these elements.

Parts markup adds a percentage (typically 15–50%) to the wholesale cost of parts and materials. Enter your markup percentage and it is calculated and displayed automatically as a separate line item. Emergency surcharges apply a multiplier (1.5x or 2x) to labor charges for after-hours, weekend, or emergency calls. The surcharge is applied to labor only (not parts) and appears as its own line item for transparency. Both are industry standard practices — no US state regulates or caps either one.

Flat rate is the industry trend — customers prefer knowing the total cost upfront, and it rewards efficient plumbers who complete jobs quickly. Hourly is better for diagnostic work, complex repairs with uncertain scope, or commercial time-and-materials contracts. Many plumbers use flat rate for standard services (drain cleaning, water heater installation) and hourly for troubleshooting and custom work. This invoice supports both — choose the structure that matches each job.

Yes. Plumbing is a licensed trade in all 50 states. States including California (Bus. & Prof. Code § 7030.5), Florida (§ 489.119), Texas (TSBPE), Arizona, Washington, Nevada, Oregon, North Carolina, and Minnesota explicitly require your license number on all invoices, proposals, contracts, and advertising. Even in states without an explicit invoice requirement, including your license number is universal industry practice — it builds customer trust, demonstrates compliance, and may be required to enforce mechanic's lien rights or collect on disputed invoices. This invoice makes the license number a required field.
