About United States Plumbing Invoicing
United States Plumbing invoices must comply with local tax regulations. The applicable tax is Sales Tax. Plumbing invoices must capture the full cost picture of a job: the call-out or mobilisation fee, time on site, parts and materials marked up appropriately, and any emergency or after-hours surcharges. Because materials costs vary widely — a simple washer versus a new boiler — itemising parts separately from labour protects you from disputes and gives clients the transparency they expect. Many plumbers also bill a fixed diagnostic fee before providing a repair quote, which should appear as a distinct line item.
Frequently Asked Questions
Should plumbers charge a call-out fee separately from labour?
Yes. A call-out fee covers travel, vehicle costs, and the time spent mobilising to site regardless of how long the job takes. Listing it separately from your hourly labour rate avoids confusion — clients understand they pay a fixed amount to have you arrive, then an hourly rate for the work itself.
How should plumbers invoice for materials and parts?
List parts and materials as a separate line item showing either the actual cost or a marked-up price (a 10–30% markup on trade prices is common and widely accepted). Keep receipts in case a client queries the cost. For large jobs, some plumbers split parts into a separate 'materials invoice' alongside the labour invoice.
What are standard payment terms for plumbing jobs?
Residential plumbing jobs are almost always due on completion — clients pay when the work is done and they're satisfied. For larger commercial projects or boiler installations, a 25–50% deposit upfront to cover materials is standard, with the balance on completion. Net 14 is reasonable for repeat trade customers.
Do plumbers need to charge VAT or GST?
In the UK, plumbers must register for VAT once turnover exceeds £90,000 and charge 20% on labour and most parts. In Australia, you need an ABN and must charge 10% GST once turnover exceeds $75,000 AUD. In the US, labour on plumbing services is generally not subject to sales tax, but parts may be taxable depending on the state.
Do I need to charge sales tax on my invoices in the US?
There is no federal sales tax in the United States. Whether you need to charge sales tax depends on your state, the type of goods or services you sell, and whether you have nexus in the buyer's state. Some states (e.g., Oregon, Montana, Delaware, New Hampshire) have no sales tax at all, while others tax services differently from tangible goods. Check with your state's department of revenue for the rules that apply to your business.
What tax ID should I include on US invoices?
US invoices do not legally require a tax identification number in most cases. However, business clients may request your EIN (Employer Identification Number) or ask you to complete a W-9 form for 1099-NEC reporting if they pay you $600 or more in a calendar year. Sole proprietors without an EIN may use their SSN, though applying for an EIN is recommended for privacy.
Are there federal invoicing requirements in the United States?
The US does not have a federally mandated invoice format. However, best practice is to include your business name and address, the client's details, a unique invoice number, an itemized list of goods or services, the total amount due, payment terms, and the date of issue. Some states and industries may have additional requirements.
