Free Plumber Invoice Generator

A plumber's invoice must separate parts from labour, with model numbers on major fixtures so the client has a warranty record. List the service call or diagnostic fee as its own line, distinct from the labour to do the actual repair. State after-hours, weekend, or emergency call-out multipliers clearly if they apply, and reference the permit and inspection fees when the jurisdiction requires them. Include warranty terms on workmanship, typically one year, alongside the manufacturer warranty on parts. The most common mistakes are quoting a flat install fee with no parts or labour split, leaving the client to wonder why the labour is so high; forgetting to charge the after-hours multiplier on a late-night emergency call; not pulling or invoicing the permit, which exposes both you and the homeowner to code violations and resale problems; and hand-writing invoices that get lost, leading to disputes six weeks later when the client has forgotten what was done. One practical tip: collect payment at job completion, not on Net thirty, since plumbing is emergency work and clients expect to pay when the water runs again.
