The quote that comes in lowest is often the one that ends up costing the most — because the missing detail is exactly where the cost gets added back later. A renovation quote is only useful if it’s a BOQ: a bill of quantities that lists every item, material, brand and exclusion separately, so you know precisely what you’re paying for and what you aren’t. A single “interior work — ₹X” line, or a flat per-square-foot rate, hides all the decisions that matter. Here’s what a complete BOQ should contain, the red flags that signal a quote will grow, and how to compare two quotes honestly.

What a complete BOQ contains

A proper room-wise BOQ breaks the project down so nothing is assumed. For each room and each trade, you should see:

• Scope of work, item by item — not “kitchen work” but “base units, tall unit, overhead units, countertop, dado tiling, sink, hardware” listed separately.
• Materials with grade and brand — plywood grade (BWR/BWP) and brand, laminate brand, hinge and channel brand (Hettich, Ebco, Hafele), tile brand and size, paint system, waterproofing system.
• Quantities — running feet of furniture, square feet of flooring or ceiling, number of points, litres or coats of paint.
• Labour, where it’s separate from material.
• Inclusions and exclusions, stated plainly — what’s in the price and what will be charged extra (for example, civil repair found after demolition, or appliances).
• Payment schedule tied to stages, and the timeline.

If your quote doesn’t show grade, brand, quantity and exclusions, it isn’t finished — and the gaps are where the surprises live. The same itemised discipline runs through every project our civil contractor in Thane team quotes.

Why the per-square-foot rate hides things

A “₹X per sq ft, all-inclusive” number is easy to compare at a glance, which is exactly why it’s used — but it tells you nothing about what is included at that rate. Two firms can quote the same per-square-foot figure with completely different plywood grades, hardware brands and waterproofing systems underneath. The itemised BOQ is harder to skim, but it’s the only quote that can’t quietly expand once work starts, because everything is already named and priced. For a sense of what realistic budgets look like by flat type, our guide to interior design cost in Thane breaks it down room by room.

Red flags in a quote

A few signals that a quote will grow or disappoint:

• Lump-sum lines — “interior work”, “civil work”, “miscellaneous” without a breakdown.
• “Premium” or “branded” with no names — material quality is only real when the brand and grade are written down.
• No exclusions listed — if nothing is excluded, everything not foreseen becomes an extra later.
• A large upfront payment before any work, with little tied to milestones.
• An implausibly fast timeline — usually a sign the waterproofing cure or prep stages will be cut.
• No mention of who supervises the site.

How to compare two quotes properly

Put the two BOQs side by side line for line, not total against total. Where one is cheaper, find out why — is it a lower plywood grade, unbranded hardware, fewer coats of paint, no epoxy grout in the wet zone? Often the cheaper quote is cheaper because it’s specifying less, not because the firm is more efficient. Normalise the materials (same grade, same brands) and the gap usually narrows or reverses. Then weigh the things a BOQ can’t fully show: who handles the civil work, who supervises, and what happens after handover — the criteria in our guide on how to choose an interior designer in Thane.

Why one contract makes the BOQ honest

When design and civil sit with one team, the BOQ can be written against the real flat from the start — wall chases, waterproofing, levelling and points all planned and priced before finishes, instead of “discovered” mid-project by a second contractor. That’s the logic behind our turnkey interior design work, and it’s why a single accountable quote tends to hold where a split one drifts. Material choices that affect the BOQ — which grades survive Thane humidity — are covered in our guide to the best monsoon-proof materials for Thane homes.

Frequently Asked Questions

What is a BOQ in interior design? A BOQ (bill of quantities) is an itemised quote that lists every item, material grade, brand, quantity, labour and exclusion separately — so you know exactly what you’re paying for, rather than a single lump-sum or per-square-foot figure.

Why is an itemised quote better than a per-square-foot rate? Because a per-square-foot rate hides what’s included. Two firms can quote the same rate with different plywood, hardware and waterproofing underneath. An itemised BOQ can’t quietly grow mid-project because everything is already named and priced.

What are the warning signs in a renovation quote? Lump-sum lines with no breakdown, “premium” materials with no brand names, no exclusions listed, a large upfront payment, an implausibly fast timeline, and no mention of who supervises the site.

How do I compare two interior design quotes? Compare them line for line, not total against total. Find out why a cheaper quote is cheaper — usually lower grades or unbranded hardware — then normalise the materials and weigh civil responsibility, supervision and after-handover support.

Should the quote list material brands? Yes. Plywood grade and brand, laminate, hinge and channel brand, tile brand and size, paint and waterproofing systems should all be named. “Branded” without a name isn’t a specification.
