Plumbing invoices are usually settled the same day the work is done, so they need to be clear on the spot. Separating the service call, the parts and the labor lets a customer see exactly what they are paying for before they hand over a card or a check.

What to include on a plumbing invoice
- Your business name, license number and contact details. Include your license number where your state requires it.
- The customer's name and service address. Note it if it differs from a billing address on file.
- A unique invoice number. Makes it easy to pull up the job later for a warranty question.
- Service call fee, parts and labor as separate lines. Do not combine them into one repair charge.
- Permit and inspection fees, where the job requires them, at the amount charged by the permitting office.
- Warranty information, noted so the customer knows what is covered and for how long.
How to word your line items
A customer looking at "Plumbing repair, $1,390" has no way to tell if that is fair. The same total broken into a service call, a named part and labor is easy to check against a quote.
- Service calls: "Service call and diagnosis" as a flat fee, whether or not further work is approved.
- Parts: name the specific part, such as "Water heater, 40-gallon (part)", so the customer can see the manufacturer cost versus your labor.
- Labor: a flat installation fee or hourly rate, shown separately from the part it relates to.
Payment terms for plumbing work
- Due on completion for most residential repairs, since the job is finished in a single visit.
- A deposit for special-order parts, such as a specific fixture the customer chose, since you cannot return a custom order.
- Net 15 or Net 30 for commercial or property management accounts billed monthly.
