Free Plumber Invoice Template & Generator

Your invoice needs to show exactly what you did and what parts you used. Break down labor hours separately from materials because accountants need this for their records and some clients can claim tax deductions on repairs versus improvements. Include the service address if it's different from the billing address. Describe the work in plain language like "replaced wax ring and reset toilet" instead of just "bathroom repair" because property managers and insurance companies will reject vague descriptions.

Most plumbers collect payment when the job is done, especially for residential service calls and small repairs. For bigger jobs like whole-house repiping or bathroom remodels, ask for one third upfront to cover materials, another third at roughin, and the final third at completion. Commercial clients will want net 30 terms, which means you wait a month to get paid. Factor that into your cash flow.

Take photos of the work before you leave, especially for insurance jobs or problem areas you fixed. When a client questions a charge three weeks later, you can send proof of what you actually did. Also, send the invoice the same day you finish the work, not at the end of the week. People forget details fast and delay paying for work that feels like old news.
