Job costing for plumbing contractors
A plumbing job runs in stages (underground, top-out, trim), often weeks apart, with other trades in between. Costs spread out over months are easy to lose track of. JobMargin keeps every receipt and crew hour on the job, so the margin is current when you come back for the next stage.
What plumbing contractors track in JobMargin
- Stages as scope lines. Bid underground, top-out, and trim as separate lines, and they carry over to the job’s scope.
- Fixtures separately from rough materials. Owner fixture selections change. Keeping fixtures in their own category makes those changes easy to spot and bill.
- Crew hours across a long schedule. Hours post to the job whenever the crew is on it, even months apart.
- Permits and inspections tracked as costs, not forgotten.
Set up for plumbing from the first day
When you pick Plumbing as your trade, JobMargin loads these cost categories for budgets, receipts, and job costs. You can rename or add your own at any time.
- Materials
- Labor
- Fixtures
- Equipment
- Permits
- Fuel
- Subcontractor
- Other
Bid line items use the units plumbing actually bid in: linear feet (LF), each (EA), and lump sum (LS).
Example: what a plumbing job looks like mid-way
Underground and top-out are complete; trim is waiting on fixtures.
| Cost category | Budget | Spent so far |
|---|---|---|
| Materials | $12,500 | $10,900 |
| Labor | $21,000 | $13,100 |
| Fixtures | $9,500 | $0 |
| Equipment | $1,800 | $1,700 |
| Permits | $700 | $700 |
| Other | $1,000 | $350 |
| Total | $46,500 | $26,750 |
Rough materials and labor are in line, with 62% of labor used and trim still ahead. The open question is fixtures: nothing bought yet. If the owner upgrades selections, write the change order before you order, not after.
