| Line | Unit | Qty | Rate (₹) | Amount (₹) |
|---|---|---|---|---|
| Bathroom concealed CPVC line | point | 8 | 950 | 7,600 |
| CPVC pipe 3/4 inch | metre | 22 | 140 | 3,080 |

| Blocked drain clearing | line | 1 | 1,200 | 1,200 |
| Pressure test of new lines | job | 1 | 800 | 800 |
| Emergency call-out after 8 pm | visit | 1 | 500 | 500 |

A point is one outlet such as a tap, a shower or a WC inlet. Count them with the customer before you start. The count on the invoice then matches what they saw.
What a plumber bill format should show
| Field | Reason |
|---|---|
| Job number | Ties the bill to the call and the visit date |
| Site address and flat number | Society offices ask for it before releasing payment |
| Materials supplied by | You or the customer, line by line |
| Pipe type and size | CPVC, UPVC or GI and the diameter |
| Pressure test result | Proves the line held before tiles went back |
| Leak warranty | Months covered on the lines you fitted |
| Exclusions | Tiles broken for access, wall repair, painting |
The exclusions line saves arguments. A customer who reads it before work starts does not expect free tiling.
Small job or full bathroom
Plumbing work comes in two sizes. Each one gets paid differently.
| Job size | Example | How it is paid |
|---|---|---|
| Call-out repair | Leaking tap, blocked drain, flush valve | Full amount on completion |
| Renovation | New concealed lines in two bathrooms | Advance for material, balance after the pressure test |
| Building contract | Plumbing for a G+3 building | Running bills by floor |
On a renovation, ask for the material money first. CPVC pipe, fittings and a diverter can cost more than your labour.
Collecting a renovation on WhatsApp
Fixwell takes ₹8,000 as advance for material on the Adyar bathroom. Three days later the lines pass the pressure test. The plumber sends the bill from the site.
Good evening Mrs. Narayanan. The new lines in your bathroom passed the pressure test today. Bill FW-2026-208 is attached for ₹19,280. Your advance of ₹8,000 is deducted. The balance is ₹11,280. UPI fixwell@okaxis. The tiler can start tomorrow once this is cleared.
Send it while you are still at the flat. A customer who just saw dry joints pays on the spot.
Material at cost or with a margin
Some plumbers bill material at the shop price and earn on labour. Others add a margin and charge a lower labour rate.
- At cost. Attach the shop bill and write «material at actuals» on the line.
- With margin. Write one rate per item and do not attach the shop bill.
- Customer supplied. Bill labour only and write «material by customer» on the job.
Pick one way per customer. Switching between jobs leads to questions.
Plumbing billing mistakes
- Writing «plumbing work» as one line. The customer cannot see what changed hands.
- No point count agreed before the job. The count turns into a fight later.
- Forgetting the call-out charge on a night visit.
- Billing the pressure test without recording the result.
- No warranty period written. Every drip a year later becomes your free visit.
- Leaving the advance off the final bill. The customer feels charged twice.
Running bills on a building contract
A plumbing contractor on a new building bills by floor or by shaft. Each running bill shows work done to date.
| Running bill | Work covered | How it is checked |
|---|---|---|
| RA bill 1 | Sleeves and inserts in slabs, floors 1 to 4 | Site engineer counts sleeves |
| RA bill 2 | Vertical stacks and shafts | Metres of pipe per shaft |
| RA bill 3 | Bathroom points on every floor | Point count per flat |
| Final bill | Fixtures, testing and handover | Pressure test report signed |
Builders often hold back a part of each bill until handover. Write the held amount on every running bill. The final bill then releases it in one line.
Warranty visits after the job
A leak inside the warranty period is a free visit for your own work. A leak from a fitting the customer bought is a paid visit.
Write «warranty visit, no charge» on a zero bill and keep it with the job. The record proves the warranty was honoured if the customer complains later.
