Measurements and Running Bills for Plumbing Contractors

Work done on site is measured stage by stage and turned into running bills. Retention, deductions and the final bill are tracked against the same job.

Measurement before the bill

Builders pay for plumbing work that has been measured. The supervisor’s measurement sheet is the base for the bill.

Quantities by stage

Metres of line laid, points fitted, fittings fixed and tests done are entered against the job’s stages and the unit they belong to.

Agreed with the builder

A measurement carries a flag for whether the builder’s engineer has signed it. A bill built on a signed sheet is easier to defend.

Previous and current

A running bill shows what was billed before and what is new in this period, so nothing is billed twice.

Extra and reduced work

Approved changes appear as their own lines. They are priced at the agreed rate, not folded into the original quantities.

Running bills and the final bill

Each running bill lists the work measured since the last one, at the quoted rates. Deductions that the contract allows can be entered, and retention is held back as the contract states. The final bill adds up the job and shows the retention still to be released. Retention terms differ from one builder to another, so they are set for each client. A client’s dues are visible from the bill.

From bill to money

A bill posted here goes to the invoice and receipt module. Payments received are matched against it. The office can see which running bill is paid, which is part paid and which is waiting for the builder’s approval.

What this page does not do

The software does not decide what a builder will accept. Rates, deduction rules, retention terms and any tax treatment are agreed in the contract, and the firm’s accountant advises on tax.

FAQ

Frequently asked questions

Can one measurement sheet cover many flats?

Yes. Quantities are held by flat, floor or block, and the running bill can total them or list them separately.

Does it keep a retention balance?

Yes. Retention held on each bill adds up against the job, and the amount still to be released is visible until the client pays it.

Can a measurement be corrected after the bill?

A correction is recorded as a new entry with a note. The earlier figure remains in the history so the change can be explained.

Does it print bills in a builder’s own format?

Often yes. Many builders ask for a set layout, and bill formats are matched during set-up. Larger changes are quoted separately.
