Pluming Bookkeeping

Keep your plumbing business profitable, compliant and cash‑flow positive.
At Perfect 10 Bookkeeping, we specialize in bookkeeping for plumbing companies—from solo owner‑operators to growing service teams. We understand the unique challenges plumbers face: job‑costing individual service calls, handling vendor bills for materials, invoicing quickly, staying compliant with Colorado’s sales/use tax rules and keeping an eye on profit margins. Our plumbing bookkeeping services let you focus on serving customers while we organize your finances.

Who We Serve

  • Residential and light‑commercial plumbing contractors

  • Service and repair plumbers (water heaters, pipes, faucets, fixtures)

  • Plumbing businesses with maintenance plans or service agreements

  • New construction and tenant‑finish plumbers operating under lump‑sum or time‑and‑materials contracts

Deliverables & Features

  • Clean, up‑to‑date books tailored for plumbing. We set up a chart of accounts that separates service revenue from install revenue, parts, labor and overhead.

  • Accurate job costing. QuickBooks’ Projects feature helps track labor, tools and subcontractors by job so you know which types of work are profitableservicetitan.com.

  • Streamlined invoicing and A/R. We configure QuickBooks to handle flat‑rate and time‑and‑materials billing. This includes deposits, progress billing and field paymentsservicetitan.com.

  • Efficient accounts payable. Vendor bills for pipes, fittings and fixtures are entered promptly and matched with purchase orders. We help you capture early‑pay discounts.

  • Payroll integration. We can coordinate with QuickBooks Payroll (or your preferred payroll service) to capture technician labor costs and track overtimeservicetitan.com.

  • Sales and use tax compliance. Colorado treats contractors differently depending on contract type: plumbers under lump‑sum contracts are consumers of building materials and owe sales tax on purchasestax.colorado.gov, whereas plumbers under time‑and‑materials contracts must collect and remit tax on the materials portion of invoicestax.colorado.gov. We configure your books accordingly and work with your CPA for filings.

  • Monthly financial package. You’ll receive a profit‑and‑loss statement, cash‑flow overview, balance sheet and job‑profitability reports, plus a 30‑minute call to review trends and answer questions.

  • Key performance indicators. We help track gross margin, average ticket size, labor efficiency and materials percentage. Industry guidance suggests plumbing businesses aim for gross profit margins around 60–62 % to support healthy net marginsgoduo.co.
