How to Read an Interior Design Quotation in India, Line by Line

An interior design quotation in India usually runs 8 to 20 pages, but it always reduces to five sections: civil work, carpentry, finishes, electrical, and payment terms. Read it with three checks. One, what unit each line is measured in — sq ft of shutter surface, running feet, or a lump sum. Two, whether every material line names a brand and a grade, not just "plywood" or "laminate". Three, whether payments are staged against completed work, not calendar dates. In 2026, two quotations for the same 3 BHK can differ by ₹4–6 lakh purely on what is silently excluded. Below is a realistic sample quotation, annotated section by section, so nothing slips past you.

Quotation vs estimate: not the same document

A quotation is a designer's or contractor's offer to do specific work at specific prices — once you sign, it is the commercial backbone of your project. An estimate is a neutral number you use before that conversation starts. If you have not got one yet, run your floor plan through the interior cost calculator first; walking in knowing the fair range for your home changes how the negotiation goes. For context, the median 3 BHK came to ₹30.2 lakh across 48 completed AI estimates on HeyBuddy (Aug–Sep 2026), so a ₹14 lakh quotation for a full 3 BHK should make you ask what is missing, not celebrate.

The sample quotation, summarised

The figures below are an illustrative composite for a mid-range 3 BHK of roughly 1,100 sq ft carpet area — rounded, anonymous, and typical of what lands in a Bangalore or NCR inbox in 2026. Your numbers will differ; the structure should not.

Section	What it covers	Sample amount	Rough share
Civil & plumbing	Dismantling, tiling, waterproofing, plumbing shifts	₹1,80,000	12%
Carpentry	Wardrobes, kitchen, TV unit, beds, crockery unit	₹8,20,000	57%
Finishes	Painting, false ceiling, wallpaper, polish	₹2,60,000	18%
Electrical	New points, rewiring, switches, light fixtures	₹1,40,000	10%
Site, cartage, cleaning	Material lifting, floor protection, deep clean	₹40,000	3%
Subtotal		₹14,40,000
GST @ 18%	On the works contract	₹2,59,200
Total		₹16,99,200

If any of those five sections is absent from your quotation, it has not disappeared — it has moved into your future as a mid-project surprise.

Section 1: Civil work — where "as per actuals" hides

Good civil lines read as quantity × rate: "Bathroom wall tiling, 180 sq ft @ ₹110/sq ft including adhesive". Market rates in 2026 for tiling labour plus material prep run ₹90–150 per sq ft; dismantling a bathroom, ₹8,000–15,000.

Red flags to circle:

• "As per actuals" on plumbing or breaking work. It means the price is undefined and the meter starts when your wall is already open.
• No waterproofing line in a bathroom retile. Redoing waterproofing costs ₹40–80 per sq ft now; skipping it costs a neighbour's ceiling later.
• Lump-sum civil ("Civil works: ₹1,50,000") with no measurements. You cannot compare it, and you cannot contest it.

Section 2: Carpentry — 57% of the money, 90% of the traps

This is the section to read twice. Three things decide whether ₹8,20,000 of carpentry is fair.

The measurement basis

Wardrobes and kitchens are billed per sq ft of shutter (front) surface — a 7 ft × 10 ft wardrobe is 70 sq ft. Confirm in writing that the rate includes the carcass, internal shelves, and back panel. A common trick is a low headline rate that bills internals separately, which quietly adds 20–30%. Finished woodwork in 2026 runs roughly ₹1,250–1,700 per sq ft in laminate and ₹1,900–2,600 in acrylic or PU, depending on hardware.

The material specification

Every carpentry line should name board type, grade, thickness and brand: "18mm BWR-grade plywood, ISI 303-marked, [named brand]". If your quotation just says "plywood", you will receive the cheapest board that fits the word. Grades matter enough that we wrote a separate decoder — see MR vs BWR vs BWP plywood grades before you sign anything that mentions "commercial ply" for a kitchen.

The substitution clause

Look for the phrase "or equivalent" after brand names. It is reasonable as protection against stock-outs, but it should say substitutions need your written approval and must be the same grade and price band. Hardware deserves its own line: hinge and channel brand, and exactly how many soft-close units are included, because "soft-close" often means two drawers out of ten.

Section 3: Finishes — the per-sq-ft illusions

Painting in 2026 costs ₹20–30 per sq ft for a repaint with premium emulsion and putty touch-ups, and ₹28–45 for fresh walls with two full putty coats and primer. The quotation should state paint brand and line, number of coats, and whether ceilings are included — "Painting: ₹90,000 lump sum" tells you none of that.

False ceilings run ₹75–95 per sq ft for gypsum in metro cities; check whether the rate includes the peripheral cove and paint, or only the board. Texture and wallpaper walls are best quoted per wall, not per sq ft, so you can compare options directly.

Section 4: Electrical — count the points

Honest electrical quotations price per point: one point is one switch, socket or light outlet, wired back to the board. In 2026, a new point with ISI-marked copper wiring and a mid-range modular plate runs ₹550–900 depending on city and conduit length. So the sample's ₹1,40,000 implies roughly 160–250 points — plausible for a 3 BHK with cove lighting.

Red flags: "electrical as per actuals" (same trap as civil), no mention of wire brand, and light fixtures bundled invisibly into the number. Fixtures should be a separate provisional sum you control.

Payment terms — the page people skip

This half-page decides who holds the leverage for three months. A fair 2026 schedule looks like:

• 10% on booking (design freeze)
• 40% when material reaches site (verify the material against the spec before paying)
• 40% at carcass/installation stage, against visible progress
• 10% only after the snag list is closed

Red flags: anything above 50% before material reaches your site, milestones tied to dates instead of work ("30% on 15th of month"), and the absence of a final holdback — that last 10% is the only reason snag lists get finished. GST at 18% should appear as its own line with a proper tax invoice promised; a "no GST if you pay cash" offer also removes your paper trail and warranty.

What a missing line item means

Run this absence checklist before signing. Each missing item is a change order waiting to be priced at a premium, mid-project, when you cannot say no:

• Cartage and labour for material lifting (no service lift = real money)
• Floor and lift protection during work
• Deep cleaning at handover
• Appliance installation (chimney, hob, geysers)
• Loft covering, skirting, curtain rods
• Debris disposal

Also missing from many quotations: the designer's own fee, if you hired design and execution separately. How that fee is structured — per sq ft, percentage, or lump sum — is its own subject, covered in what interior designers charge.

Cross-check before you sign

Get at least two comparable quotations — same scope, same material grades — before committing; verified interior designers in Bangalore will generally re-quote against a written specification without fuss, and a firm that resists itemising is telling you something. Then compare the totals against your neutral estimate. If a quotation is far below it, the gap is usually sitting in the grades, the exclusions, or the payment terms you just learned to read.

Frequently asked questions

What is the standard interior design quotation format in India?

There is no legally standard format, but a complete quotation has five sections: civil and plumbing, carpentry, finishes, electrical, and payment terms, plus GST at 18% shown separately. Each line should carry a quantity, a unit (sq ft, running ft, or points), a rate, and a material specification with brand and grade. Lump sums and "as per actuals" lines are where disputes start.

How much GST applies to interior work in 2026?

Interior fit-out is treated as a works contract and attracts 18% GST on the contract value. It should appear as a separate line on the quotation and you should receive a proper tax invoice. Paying cash to "save GST" removes your paper trail, weakens warranty claims, and usually saves less than negotiating the base price properly would.

How much advance is normal on an interior quotation?

Around 10% at booking is standard, with the bulk paid in two stages against material delivery and installation progress, and a final 5–10% held back until the snag list is closed. Treat any demand for more than 50% before material physically reaches your site as a serious red flag, however reputed the firm.

Why do two quotations for the same home differ by lakhs?

Usually not because one firm is greedy — because the two documents describe different things. Different plywood grades, different hardware counts, different exclusions (cartage, cleaning, appliance installation), and different measurement bases can move a 3 BHK quotation by ₹4–6 lakh. Normalise both quotations to the same written specification before comparing totals; the cheaper one often stops being cheaper.
