Why Invoha

The Free Plumbing Invoice Template for Contractors

Invoha is a free plumbing invoice template built for licensed plumbing contractors who need professional invoices without the overhead. Skip the complicated billing software, monthly subscriptions, and sign-up forms. With Invoha you get a plumbing invoice app that tracks plumbing compliance, permit details, job site addresses, warranty information, and water heater/fixture specifications — all from a single, professional plumbing invoice that works locally in your browser.

Built for Plumbers & Plumbing Contractors

Plumbing work carries unique documentation requirements. A water heater replacement needs a different invoice than a commercial repiping project. Invoha's plumbing invoice template adapts to both — from permit numbers and IPC code references to water heater make/model and fixture details, every field is designed around how plumbers actually work. Whether you are clearing a drain, replacing a water heater, or roughing in a new construction, this plumbing invoice template captures the right details the first time.

Plumbing Compliance & Permit Tracking

Every plumbing job requires proper documentation. Record permit numbers, issuing authorities, inspection dates, and results directly on the plumbing invoice. Reference IPC code sections, water heater specifications, and fixture details. This information is clearly displayed on the invoice preview and persists in your browser for repeat use — no re-entering the same compliance details for every job.

Job Site Address Separation

Plumbers often work at job sites that are different from their office address or the customer's billing address. The plumbing invoice template separates the customer address from the job site address, so the invoice clearly shows where the work was performed. This is critical for inspection records, warranty validation, and customer reference.

Warranty Details

Include parts warranty and labor warranty periods, plus warranty notes. The warranty section appears at the bottom of the plumbing invoice, giving the customer a clear record of coverage. This builds trust and reduces warranty disputes. The warranty fields are optional — skip them for quick estimates or small jobs.

Country-Specific Compliance Labels

Select your country to automatically update the license and insurance labels: plumbing contractor license for the US, Gas Safe Register for the UK, master plumber licence for Canada, and state-based plumbing contractor licence for Australia. The plumbing invoice adapts to match your jurisdiction's requirements.

Free, Private & No Sign-Up

Invoha is a free plumbing invoice template with no sign-up required. Your work is stored locally in your browser's storage — nothing is sent to a server. This means your invoices, client details, and company information remain private. No account, no email, no password. Just open the page and start creating.

What Is a Plumbing Invoice Template?

A plumbing invoice template is a pre-formatted billing document designed specifically for licensed plumbing contractors. Unlike a generic invoice, a plumbing invoice template includes dedicated fields for permit numbers, IPC code references, water heater make/model and serial numbers, fixture details, and job site addresses — details that are essential to plumbing work but irrelevant to most other trades.

Plumbers handle everything from residential drain clearing and water heater installations to commercial repiping and sewer line replacements. Each job type demands different documentation. A self employed plumber invoice template needs to capture license and insurance information, compliance data, and warranty coverage alongside the standard line items for labor and materials.

Using a free plumbing invoice template means every bill looks consistent, professional, and complete. Your clients see a detailed breakdown of the work performed, and you have a clean record for tax season, warranty claims, and inspection documentation. Whether you send one invoice a month or fifty, a proper plumbing invoice sample keeps your billing accurate and your business credible.

Plumbing Invoice Requirements by Country

Plumbing invoicing rules differ by country — what you put on a US invoice isn't what the UK, Canada, or Australia requires. Here's what you need to know about licensing, compliance, and tax requirements for plumbing invoices in each country.

United States — IPC & Sales Tax

  • Most US states require a plumbing contractor license at the state or municipal level. Include your license number on every invoice for compliance and credibility.
  • IPC (International Plumbing Code) references on invoices document that work meets current safety standards. Record permit numbers, inspection dates, and results.
  • Sales tax rules vary by state — 45 states plus DC impose sales tax. Labor is taxable in some states but not in most. Show tax as a separate line item.
  • Invoha's plumbing invoice template includes dedicated fields for license number, permit tracking, IPC code references, and dual tax fields.

United Kingdom — Gas Safe Register & VAT

  • VAT registration is required once taxable turnover exceeds £90,000 per year. Standard rate is 20%, reduced rate 5% for certain installations.
  • Gas Safe Register is mandatory for any gas plumbing work in the UK. While not always legally required on invoices, including your registration number demonstrates compliance and professionalism.
  • Part G building regulations require certain domestic plumbing work to be notified to local building control. Record notification numbers on your invoice.
  • Invoha supports dual tax fields for VAT and labels compliance fields as "Gas Safe Register #" when you select the UK.

Canada — Master Plumber & GST/HST

  • GST/HST registration is required once worldwide taxable supplies exceed $30,000. Rates vary by province — 5% GST in Alberta, 13% HST in Ontario, 15% HST in Atlantic provinces.
  • Master plumber licence is required in most provinces. Include your licence number and inspection details on invoices for residential and commercial plumbing work.
  • Include your permit number and inspection details on invoices for plumbing work requiring municipal approval.
  • Invoha supports dual tax fields — use tax1 for GST and tax2 for provincial PST or QST where applicable.

Australia — ABN & State Licences

  • GST is 10% on most goods and services. Registration is required once annual turnover reaches $75,000. Tax invoices must show the words "Tax Invoice", your ABN, and the GST amount.
  • An Australian Business Number (ABN) is required on all business invoices. Without your ABN, the client must withhold 47% of the payment under PAYG rules.
  • State plumbing contractor licences vary — NSW requires a contractor licence for work over $5,000, QLD requires QBCC registration for work over $3,300.
  • Invoha's country selector labels compliance fields as "ABN" and "Plumbing Contractor Licence #" for Australian plumbers.
