Plumbing trade · Per-job materials

Per-job material records for independent plumbers

A water-heater swap and a leaky-fitting call can both send you to the supply house in the same morning, and you'll grab fittings off the truck for a third job. If those materials aren't tied to a job, the customer invoice ends up short and you cover the gap. Cash Workspace gives you one place to record each supplier run against the job and customer, with the receipt attached.

The problem

Why plumbing materials slip off the invoice

You buy fittings and fixtures for several jobs at once and use truck stock without noting it. With no record per job, billable materials vanish before invoicing.

  • One supplier receipt mixes a water heater for one job with fittings for another.
  • PVC, copper, and fittings pulled from the truck never get billed.
  • Fixtures the customer picked out get bought and forgotten as a line item.
  • Permit fees for a re-pipe go unrecorded.
  • By invoice day you can't recall which materials belonged to which customer.

The workflow

Record every supply run against the job

Tie materials to the customer while you still remember what went where.

  1. 1

    Record at the supply counter

    After a run, record the vendor, date, and amount and attach the receipt before the next call.

  2. 2

    Tag customer and job

    Note the customer and a job tag — 'Reyes — water heater replacement' — so materials map to the invoice.

  3. 3

    Split shared receipts

    When one receipt covers two jobs, make a record per job with its portion and attach the receipt to both.

  4. 4

    Capture truck stock used

    Record fittings and pipe pulled from the truck against the job so they get billed.

  5. 5

    Pull at invoice time

    Open the job's material records when you bill, so every fixture, fitting, and permit lands on the invoice.

FAQ

Plumber material records FAQ

How do I track fittings I use from truck stock?
Record them against the job just like a supplier run, noting what you used and an estimated amount, so the materials get billed and the job shows its real cost. Bulk restock purchases for the truck go in a separate folder.
Should a water heater be recorded differently from fittings?
Record both against the same job, but tag the water heater as a fixture or appliance and the fittings as materials. The separate tags make the job's cost breakdown and the customer invoice clearer.
Does Cash Workspace read my supplier receipts?
No. You enter the vendor, date, and amount and attach the receipt. Cash Workspace keeps the record and the receipt together against the job so materials are easy to match to the customer.
