A proper itemised quotation has 6 mandatory sections. Anything less is hiding something. Here's exactly what to demand — and what good quotes from Chennai's top firms actually contain in 2026.
Room-wise listing of every space being designed: living room (8 × 12 ft), master bedroom (10 × 12 ft), kitchen (8 × 10 ft), 2 bathrooms, foyer, etc. Plus exclusions explicitly stated (e.g., "electronic appliances not included", "curtains by homeowner", "soft furnishings beyond included BOQ excluded").
For every component:
Separate annexure listing brand + model for every category: plywood, hardware, paint, sanitaryware, wiring, lighting, tiles, laminates, veneer. Without this, "premium quality materials" is meaningless.
Item total → discount (if any) → sub-total → GST (18%, shown separately) → grand total. With clear "all-in" vs "exclusions" breakdown.
Industry-healthy schedule: 10% on contract signing (booking advance). 25% on material order placement. 25% on factory production complete. 25% on site installation start. 15% on snag clearance + handover. Total = 100%.
Warranty terms (10/5/2 year tiered), delivery date + penalty clause, change-order rate, exclusions, dispute mechanism. 2-3 pages, written clearly, not buried in tiny font.

Same project as a lump-sum quote elsewhere: "₹10 lakh all included". You'd save ₹2.35 lakh — but the materials would be silently MR plywood + unbranded hardware. The savings vanish in 3-4 years when things fail.
