Shop Wiring Quotation and a Warranty Dispute
A vocational graduate runs a small electrical repair and wiring shop. A customer wants a quotation for wiring a 600 sq ft two-room rented shop: 6 LED tube lights, 4 ceiling fans, 8 six-amp sockets, 2 sixteen-amp sockets for an AC point, a distribution board with a 30 mA RCD and MCBs, conduit, boxes and earthing. The customer wants a fixed price, 'best quality' material, completion in 6 days, and will pay 30% advance. Material costs the shop ₹18,500; the job needs 2 persons for 6 days at ₹700 per person per day; overhead is 10% of direct cost and the shop wants a 15% margin on cost; GST is 18%. The same customer also says that a washing machine repaired last month for ₹1,400 under a 3-month labour warranty has failed again after five weeks, and demands a free repair while threatening a bad online review.

Direct cost
- Materials: ₹18,500
- Labour: 6 days × 2 persons × ₹700 = ₹8,400
- Sub-total: ₹26,900
Overhead and margin
- Overhead 10% of direct cost = ₹2,690 → ₹29,590
- Margin 15% of cost = ₹4,439 → ₹34,029, rounded to ₹34,030
- GST 18% = ₹6,125 → total ₹40,155, quoted as ₹40,150
- Advance at 30% of order value ≈ ₹12,045
Present it as: (a) a priced material list naming cable sizes and lengths, 6 LED fittings, 4 fans, 8 six-amp and 2 sixteen-amp sockets, the AC point in 4 mm² with a 20 A MCB, DB with 30 mA RCD and MCBs, conduit, boxes and earthing; (b) labour expressed in man-days; (c) overhead and margin shown as separate lines; (d) GST; (e) exclusions - the AC unit itself, false-ceiling cutting, plaster restoration, utility charges. State that the price holds for 15 days and that any extra point is chargeable at a written rate. Showing the build-up is what makes a 'fixed' price defensible.
2. How would you handle the washing-machine complaint and the threat of a bad review?

Separate the two warranty questions - labour and parts. My invoice gave three months on labour, so if the failure is in what I did (loose connection, badly fitted part, unclamped hose) I repair it free, including the return visit. If a part I supplied has failed within its own warranty, the part is replaced under that warranty and labour may still be chargeable unless I promised otherwise; if the customer supplied the part, labour is chargeable. So the first step is diagnosis, not argument.
Say this in person and in writing: thank them, book a free inspection within 48 hours, state the finding, and state the charge (or nil) before touching anything. Keep the old part to show them. Do not answer the review threat emotionally - a calm, dated written record of the inspection and the warranty terms is the best protection, and a fair offer usually prevents the review. If the second failure is a different fault, say so clearly and offer a goodwill discount rather than admitting the first repair was bad.
3. Identify the two biggest commercial risks in this job and how you would protect yourself in writing.

1) Fixed price with a 6-day deadline. Labour is the variable: chasing conduit in a rented shop, or finding the AC point needs a longer 4 mm² run, can add two days. Protect with a written start and completion date, a clause covering delays caused by the customer (power not released, shop not vacated, AC not delivered), and a variation rate per additional point or per extra metre.
2) A 30% advance against materials bought up front. ₹12,045 against ₹18,500 of materials means the shop funds the difference. Protect with a written order stating: the advance is non-refundable once material is cut or ordered; the balance is due on completion before final connections; materials remain the shop's property until paid for; and a signed completion/handover certificate.
Also photograph the site before and after, list exact fitting brands and wattages so 'best quality' cannot be reinterpreted later, and keep copies of the GST invoice and warranty card. These documents convert a verbal dispute into a settled record.
