Professional Practice, Communication, and Entrepreneurship
What this domain tests
Professional practice questions check how you deal with customers, document work, estimate and invoice, and run a small automotive business legally and profitably.
Core rules
- A job card records the customer's complaint in their own words, vehicle details, odometer, authorised work and signature; no verbal-only approvals.
- An estimate is not a bill: it lists parts, labour, taxes and assumptions, and should be approved before work begins.
- Labour is charged by standard hours, not necessarily by clock hours; the rate is agreed in advance.
- A tax invoice shows GST registration number, HSN/SAC codes, taxable value, CGST/SGST or IGST, and total.
- Communication: listen, confirm understanding, explain in plain language, give a time and cost commitment, and follow up.
- 5S (sort, set in order, shine, standardise, sustain) and Kaizen support safe, efficient workshop practice; statutory obligations include GST, waste disposal and labour rules.
Worked example
Parts cost ₹4,500 and labour is 3 hours at ₹300 per hour, so the subtotal is 4,500 + 900 = ₹5,400. With 18% GST the tax is ₹972 and the invoice total is ₹6,372. If the customer had approved only ₹5,000, the adviser must re-confirm before fitting extra parts - the reasoning is that authorisation limits the bill, not the workshop's convenience.
Traps that cost marks
Quoting a price without checking parts availability, failing to record the customer's exact complaint, charging for work not authorised, and issuing a bill without GST details.
