Bookkeeping for Plumbers

Plumbing runs on parts, permits, and fast-moving service tickets. Generic bookkeepers lump it all into "supplies" and miss the job-level profit that tells you which work to chase. Here is how trade-native bookkeeping handles a plumbing business.

Quick answer
  • Plumbing books have to separate fixtures and job materials from durable tools and truck costs, or your margins read wrong.
  • Service calls, repipes, and new-construction work each need their own class so you can see which kind of job actually pays.
  • Subcontractors like excavation, drain-camera, and helper crews need W-9s and running 1099 totals all year, not a January scramble.
  • We keep the books inside your own QuickBooks Online file, reconcile every account, and deliver a CPA-reviewed close by the 15th.

Why plumbing books break with a generic bookkeeper

A coffee shop has one revenue line. A plumbing business has service work, scheduled installs, new construction, and warranty callbacks, and each one carries a different mix of labor, parts, and subs. When a generalist drops all of it into "income" and "supplies," you lose the one number that matters: which work made money.

  • Job materials (fixtures, copper, PEX, fittings, valves) kept separate from durable tools and equipment
  • Permit and inspection fees tracked against the job, not buried in office expense
  • Truck stock and inventory drift handled so month-end is not a guess
  • Merchant fees from field card payments reconciled, not silently eating margin

Job costing for plumbing work

We set up Class or Location tracking in QuickBooks so every job carries its own labor, materials, and subcontractor cost. That turns a vague "good year" into a Job Profit view: the repipe that looked busy but barely cleared, and the service route that quietly carries the shop. On the Crew plan and up, that visibility is part of every monthly close.

What most plumbing bookkeeping gets wrong

Materials and tools in one bucket

Copper, PEX, and fixtures are job materials that belong in cost of goods. A press tool or drain machine is a tool expense or a fixed asset. Merge them and every job looks less profitable than it really is, and your depreciation is wrong too.

Untracked warranty callbacks

A callback on last month's install has real labor and parts cost but no new revenue. Without a class for it, it quietly drags your service margin and you never see why.

Subs reconciled in January

Excavators, helpers, and drain-camera subs each need a W-9 and a running payment total. Catch it at filing time and you are chasing missing tax IDs under a deadline instead of confirming clean numbers.

Which plan fits a plumbing business

  • Crew, growing crew, job costing, FSM sync included

Plumbing bookkeeping FAQ

Do you track job costing for plumbers?

Yes. We set up Class or Location tracking so each job carries its own labor, materials, and subcontractor cost. You see job-level profit, not just a company-wide number, on the Crew plan and up.

How do you handle materials versus tools?

Fixtures, pipe, and fittings are categorized as job materials so they flow into cost of goods. Durable tools and equipment are tracked separately as tool expense or fixed assets, so both your job margins and your depreciation stay accurate.

Can you connect ServiceTitan, Jobber, or Housecall Pro?

Yes. On the Crew plan and up we sync your field-service tool to QuickBooks so deposits, merchant fees, and invoices reconcile instead of drifting apart.

What about 1099 subcontractors?

We collect W-9s, track payments to each sub through the year, and prepare 1099 totals so January is a confirmation rather than a scramble. Full 1099 filing support is included on the Shop plan.

Do I keep my QuickBooks file?

Always. We work inside your own QuickBooks Online subscription. If you ever leave, you keep the file and a clean set of workpapers. No proprietary ledger, no hostage data.

My books are months behind. Can you catch up?

Yes. Our 6-month prepaid option includes a catch-up cleanup so you start current. We scope the backlog up front so there are no surprises.
