A plumbing invoice should include your company name, license number, and contact info; the customer's name and service address; a unique invoice number; the service date; itemized parts (pipes, fittings, valves) with quantities and prices; labor hours and hourly rate; subtotal, tax, and total due; and your payment and warranty terms.

Add a separate "Emergency Service Surcharge" or "After-Hours Fee" line item to reflect the higher rate. Communicate your emergency pricing to the customer before starting work, and document it clearly on the invoice. This protects you from payment disputes.

List each part individually — pipe by the foot, valves and fittings one by one — with the unit price and quantity. Then add a separate labor line showing hours worked and your hourly rate. This transparency builds trust and makes warranty claims easier to process.

Yes. Your invoice is the paper trail for both parties. It records what work was done, which parts were installed, and when the warranty period started. Always note your labor and parts warranty in the Terms section, and keep copies for at least three years.

Most plumbers request payment within 15–30 days of the invoice date (Net 15 or Net 30). For larger jobs, a 50% deposit before work starts is common. Accepted payment methods typically include check, credit card, Zelle, or Venmo. Specify accepted methods in the Payment Details section.
