Typical Plumbing Services & Rates

Rates vary by region, complexity, and licensing requirements. Always verify local prevailing rates.

Plumbing Billing Models

Time & Materials (T&M): Charge hourly labor rates plus materials at cost with markup (typically 20-40%). Best for repair work where scope is uncertain until you open the wall.

Flat Rate Pricing: Quote a fixed price per task regardless of time. Popular with homeowners who want price certainty. Use a flat rate book or calculate from historical averages.

Project-Based: For new construction, remodels, or large installations. Break into milestones: rough-in, finish work, fixture installation.

Service Agreements: Monthly or annual contracts for commercial clients—restaurants, apartment buildings, property managers—providing priority service and regular maintenance.

Parts & Materials Markup

Plumbers typically mark up materials 20-50% above cost. Your invoice should clearly separate:

• Labor: Hourly rate × hours worked
• Materials: Itemized parts with descriptions (e.g., “3/4” SharkBite coupling," “40-gallon Rheem water heater”)
• Permit Fees: Pass-through at cost when applicable
• Service/Trip Charge: Flat fee covering travel and vehicle costs

Licensing & Compliance

Most states require plumbers to be licensed. Your invoice should include:

• License Number: Display prominently for customer confidence
• Contractor License: If operating as a contractor
• Insurance Information: General liability and workers’ comp references
• Permit Numbers: When applicable for inspected work

Tax Considerations for Plumbers

• Labor vs. Materials: Many states tax materials but exempt labor. Know your state’s rules.
• Service Contracts: Some states treat maintenance contracts as taxable services.
• Vehicle Expenses: Track mileage and vehicle costs for deductions.
• Tools & Equipment: Section 179 deductions for work vehicles and equipment.

Frequently Asked Questions

How do I invoice for emergency plumbing calls? Add a separate line item for “Emergency/After-Hours Service” with your premium rate (typically 1.5x-2x standard rates). Include the date/time to document the after-hours nature of the call. InvoiceZap lets you save emergency rates as templates for quick access.

Should I include parts receipts with my invoice? For T&M jobs, it’s good practice to attach or reference supplier receipts, especially for expensive items like water heaters or fixtures. For flat-rate work, itemizing materials builds customer trust but receipts aren’t typically required.

What payment terms are standard for plumbing work? Residential repairs are typically due on completion or NET 7. Commercial work often uses NET 30. For large projects, request 50% deposit with balance due on completion.

How do I handle warranty work? Create a zero-dollar invoice noting “Warranty Repair - No Charge” with the original invoice number referenced. This documents the work performed while maintaining warranty records.

Can I charge for estimates? Many plumbers offer free estimates for standard work but charge for complex diagnostics (camera inspections, leak detection). Be upfront about estimate fees before arriving.
