Interior quotation and BOQ checks in Kerala
Interiors has no area estimate to lean on - the BOQ is the number. Hold your own room-wise quantities before any vendor number arrives, and compare quotes line by line, never total against total.
The checks at this stage (3)
- Identical pack sent to 2+ vendors
Same production drawings, same spec sheet, same BOQ format to every bidder. Interior quotes hide everything in the annexure; the identical pack is what forces the annexures to be comparable at all.

- Quote comparison and exclusion sweep done
Each quote read line against line and against your baseline - counting bases converted, footnotes classified, and the known exclusions hunted: hardware, edge banding, transport, installation, cutouts, cleaning. Missing lines are priced before selection.

- Brand-and-grade check passed on every line
Any line carrying a brand without its grade - or the word waterproof without an actual grade - fails. Core substitution after lamination is invisible, which is exactly why the paper trail has to be complete before the factory starts.

Consider and compare: the decisions here
Carcass core material
Plywood, MDF or HDHMR inside every unit - invisible after lamination, which is why it locks on paper with grade and brand together.
PlywoodMost common
Pick it when: Kerala humidity worries you and wet areas are in scope.
Usually costs more
- Best moisture tolerance of the three
- Strong screw-holding for hinges and racks
- Highest cost per sheet
- The classic target of invisible substitution
MDF
Pick it when: Smooth premium finishes matter and wet use will be limited.
Usually costs less
- Uniform machining, smooth faces
- Takes premium finishes well
- Moisture-sensitive - justify wet-area use
- Weaker re-fixing when hardware shifts
HDHMR
Pick it when: You want MDF's finish with more density and moisture fight.
Costs about the same
- Denser, tougher than MDF
- Routes cleanly for membrane and grooves
- Quality varies by brand - fix the brand
- Heavier units, hardware must be rated
WPC
Pick it when: Wet areas dominate and you want waterproof by composition, not by treatment.
Costs about the same
- Waterproof and termite-proof by what it is made of
- Uniform density suits factory-modular fittings
- Hardware needs the maker's fixings - plain wood screws strip
- Quality rides on the wood-plastic ratio; density must be stated
Multiwood
Pick it when: Budget wet-area units where plywood prices hurt.
Usually costs less
- Waterproof PVC or resin core, common in Kerala wet areas
- Factory-finished faces
- The name spans very different boards - composition and density must be on the spec sheet
- Sags on long spans without closer supports
Aluminium
Pick it when: Wet zones for the long haul, and a modular look is welcome.
Usually costs more
- Fully waterproof and inert to termites - the longest-lived option
- Clip assembly means units can be dismantled and moved
- Industrial look unless panelled over
- Fewer fabricators; quality rides on profile gauge and joinery
Changing your mind later: Changed after the BOQ, every panel line reprices and the cutting plan restarts - about 2 weeks; changed after pressing, it is a remade order at someone's cost.
Shutter finish
Laminate, acrylic or veneer - the surface you see and touch daily, and the biggest visible-budget lever in the whole interior.
LaminateMost common
Pick it when: You want durable, repeatable finish at the friendliest cost.
Usually costs less
- Durable and easy to live with
- Vast range, reorderable by code
- Visible joints at edges
- Premium looks need premium ranges
Acrylic
Pick it when: A high-gloss face matters and you will maintain it.
Usually costs more
- Mirror-gloss premium face
- Rich colour depth
- Scratches show and need care
- Cost climbs per shutter
Veneer
Pick it when: Real wood character matters and site polishing is acceptable.
Usually costs more
- Real wood grain, ages with character
- Re-polishable years later
- Needs its polishing system done right
- Sheet-to-sheet grain variation
Changing your mind later: A finish change after the BOQ reprices every shutter line and can reset production - a fresh pricing round and 1-2 weeks, more once material is ordered.
Hardware grade
Hinges, channels and lifts are the moving parts of the whole interior - specified as brand plus series, because the series is where the price lives.
Standard
Pick it when: Budget is tight and you accept firmer action and earlier wear.
Usually costs less
- Lowest hardware line on the BOQ
- Everywhere available for replacement
- Firmer action, earlier wear
- No soft-close comfort
Soft-closeMost common
Pick it when: Daily comfort matters - the mid path most homes settle on.
Costs about the same
- Soft-close comfort on doors and drawers
- Strong value for daily use
- Series substitution risk - check cartons
- Costlier than standard
Premium
Pick it when: Heavy drawers, tall lifts and long-life smoothness justify it.
Usually costs more
- Smoothest action under heavy load
- Longest service life
- Highest cost per unit
- Replacement stock less common locally
Changing your mind later: A hardware regrade after the BOQ reprices every unit's hardware count - a week of requoting; after fixing, swaps mean visible holes in finished carcasses.
Countertop material
Granite, quartz or solid surface - the hardest-working surface in the house, chosen with its cutouts and support in mind, not just its colour.
GraniteMost common
Pick it when: You want proven toughness and easy local fabrication.
Usually costs less
- Tough, heat-tolerant, proven
- Fabricators everywhere in Kerala
- Needs sealing against stains
- Slab-to-slab colour variation
Quartz
Pick it when: Uniform colour and low upkeep matter more than heat tolerance.
Usually costs more
- Uniform colour, low maintenance
- Non-porous, no sealing
- Heat-sensitive - trivets always
- Costlier than granite
Solid
Pick it when: Seamless joints and integrated sinks are the priority.
Usually costs more
- Invisible joints, integrated sinks
- Repairable by polishing
- Scratches and heat marks easily
- Fewer skilled fabricators
Changing your mind later: Changed after the BOQ, the top lines reprice and slab procurement restarts - 1-2 weeks; changed after templating, paid-for slab may go to waste.
What good work looks like
What your quantity baseline contains
Computed from the frozen production drawings before quotes are invited: carcass areas panel by panel, shutter counts and areas, hardware counts, top lengths - room-wise, unit-wise, with the basis stated per line. This is the sheet that inflated quantities have to argue with, and lose to.
- Quantities derived from drawings, traceable per unit
- Bases stated per line and consistent throughout
- Totals that re-add on your own calculator
- A baseline that is really a vendor quote reworded
- Quantities appearing with no drawing behind them
- Arithmetic that fails a simple re-addition
What makes interior quotes comparable
The identical pack does the work: same production drawings, same spec sheet, same BOQ format to every bidder. Then each quote converts to a common counting basis and reads line against line against your baseline - with every footnote classified as exclusion, contradiction or variation first.
- Every bidder confirming the identical pack
- All quotes converted to one basis before comparing
- Footnotes classified, none skipped
- Bidders pricing different drawing revisions
- A per-sqft quote compared raw against a per-unit one
- Exclusions surfacing after the vendor is chosen
The interior exclusion sweep, on paper
Hunted in every quote before rupees are compared: hardware, edge banding, shutters versus carcasses, transport, installation, appliance cutouts and charges, deep cleaning, putty behind units. Present or marked missing, per quote, in writing - missing lines get priced before selection, not billed after.
- Each classic exclusion found or marked missing per quote
- Cutout charges stated for hob, sink and appliances
- The sweep table filed with the quotes
- An exclusion arriving as an extra mid-fit-out
- Installation assumed included with no line saying so
- Nobody noticing no quote carried edge banding
What a complete kitchen quote line must specify
Ten parameters, every one of which was found missing in real Kerala quotes. A kitchen line that names a rate but not these is not comparable with anything.
- Core grade named: BWP 710 / BWR 303 / WPC / HDHMR — with thickness (16/17/18mm)
- Laminate type and thickness, with brand and code
- Hardware brand named (Hettich / Hafele / EBCO / standard) — and the SERIES, because one brand spans a fourfold price range
- Soft-close hinges: included or chargeable, stated
- Countertop material specified
- Edge-banding type specified
- Every accessory listed individually with a count — never 'accessories included'
- Installation and transport included, stated
- Warranty terms written down
- 'Branded ply' with no grade — the classic invisible downgrade path
- Hardware brand named, series omitted — the fourfold price range hides there

What a real quote comparison surfaced — the patterns
Findings from real side-by-side comparisons of competing interior quotes. None of these is fraud — each is a structural feature of how interior quotes are written, and each one moves the true price without touching the headline number.
- Every line DIMENSIONED: in one real comparison, four undimensioned lump-sum lines were nearly 15% of the quote — a lump sum without dimensions is a rate that cannot be verified
- A GST line, explicitly: a quote with no tax line is not cheaper, it is unfinished — the comparison is made tax-adjusted or it is fiction
- The comparison scope-NORMALISED, never total against total: the decisive view prices only the lines both vendors quote, then prices each vendor's extras separately
- A weighted average rate per square foot across all cabinet lines — single-line rates mislead in both directions: tiny panels show inflated rates (a small-area artefact, not a premium), and one low line hides a thin spec
- Accessories billed separately versus integrated, swept line by line: the same mirror appeared as a per-bedroom charge in one quote and free inside the wardrobe in the other
- Every deduction and allowance QUANTIFIED before signing: 'design charges deducted from final bill' with no amount is a discount that cannot be banked
- Line items re-added and reconciled against the stated total — real quotes arrived with sums that did not meet their own totals
- Choosing the lower headline where the higher quote carried the broader scope — the gap returns as additions at post-signature rates
- Payment structure ignored in the comparison — the cheaper quote demanding more money earlier can be the worse deal

Red flags and money traps
One vendor counts carcasses per running foot, another per square foot, a third per unit. Raw totals across different bases are noise - convert every quote to one basis, line by line, and the real price order often reverses.
Never: Compare interior totals across counting bases without converting them first.
On paper, waterproof ply can mean almost anything. A line carrying a brand without its grade - or waterproof without a grade - fails the check, because once the laminate is on, the core can never be verified again.
Reject: Any core line without type, grade and brand together. No exceptions.
