Unique Bookkeeping Challenges for Plumbing Contractors
- Service vs. project work — Plumbing companies often mix high-volume service calls with larger construction projects, each requiring different billing and job cost tracking approaches
- Flat-rate billing reconciliation — Flat-rate plumbing service billing needs to be reconciled against actual labor and material costs to ensure pricing remains profitable
- Material cost volatility — Copper, PEX, fixtures, and fittings fluctuate in price; tracking materials by job is essential to protect margins
- Warranty and callback tracking — Labor costs on warranty callbacks must be tracked separately and analyzed to identify problematic jobs or technicians
- Backflow certification billing — Specialized compliance work like backflow testing requires separate billing and tracking
- Apprentice and journeyman payroll — UA Local 78 and non-union workers have different rate structures that must be tracked correctly for prevailing wage jobs
Our Bookkeeping Services for Plumbing Contractors
Monthly Bookkeeping & Job Costing
We set up QuickBooks with plumbing-specific job costing so you can see profitability for service work, new construction, and commercial projects separately. Know which types of work make you money — and which don’t.
Service Company Revenue Tracking
We track revenue by service type, technician, and geographic area — giving you the data to make better dispatch and pricing decisions. Integration with ServiceTitan, Housecall Pro, or your dispatch software is available.
Plumbing Contractor Payroll
We run payroll for your plumbers and helpers with California-specific daily overtime and sick pay rules. For public works plumbing jobs, we prepare DIR certified payroll reports with correct prevailing wage rates.
Accounts Receivable & Collections
We track outstanding invoices for commercial plumbing work, send aging reports, and help you stay on top of slow-paying GCs and property managers. Proper AR management is critical for plumbing companies doing commercial and multi-family work.
Tax Preparation & Vehicle Deductions
Plumbing companies have significant vehicle deductions — service trucks, vans, and pipe trailers. We ensure proper documentation and maximum Section 179 depreciation on equipment purchases to minimize your tax bill.
