Work Ethics and Entrepreneurship
Domain 13 tests professional conduct and the business side of plumbing: costing, quotation, registration, compliance, and treating customers and materials honestly.
Ethics on the job
- Punctuality, honest material quality, transparent billing, and no unnecessary parts.
- Protect the customer's property, keep confidences, honour warranties, and dispose of waste legally.
Business basics
- Costing: material + labour + consumables + overhead + profit + GST.
- Register on Udyam as an MSME; register for GST once turnover crosses the threshold, which is 20 lakh rupees for services in most states.
- Keep invoices and a simple ledger, and issue a written quotation with scope, terms and validity period.
- Obtain a municipal or PWD contractor licence where required, insure against accidents, and accept digital payments.
Worked example
Quote for replacing six bib cocks. Material 6 × 450 = 2,700 rupees; consumables 200; labour 6 × 150 = 900; subtotal 3,800; overhead at 10% = 380; profit at 10% = 418; total 4,598; GST at 18% = 828; invoice 5,426. Reasoning is shown line by line so the customer can see there is no hidden charge and can compare quotations fairly.
Traps
Quoting from memory; ignoring GST and transport; no written warranty terms; buying the cheapest fitting and losing repeat work.
