What is a BOQ in interior fit-out? Format, example, and how to build one

If you run an interior fit-out or design-build firm, the BOQ is the most important document you produce — and the one most likely to quietly cost you money. It’s how you win the job, how the client holds you to a number, and how you decide, months later, whether the project made or lost margin.

“BOQ” is searched a few hundred times a month in India by exactly the people who live inside one: contractors, designers, PMC teams, and estimators. Most of what’s written about it is generic construction theory. This is the working version for interior fit-out — what a BOQ is, the format that holds up, a worked example, how to build one, and the specific place it leaks profit.

What is a BOQ?

A BOQ (bill of quantities) is a document that prices a project line by line. Instead of quoting “₹7.7 lakh for the office,” you list every item of work — each partition, each square metre of flooring, each workstation — with its quantity, its unit, and a rate. Multiply rate by quantity and you get the amount for that line; sum the lines and you have the cost of the job, built up from the bottom rather than guessed from the top.

That bottom-up structure is the whole point. A lump sum hides your assumptions; a BOQ exposes them. The client can see what they’re paying for, you can defend every number, and when scope changes — and in fit-out it always changes — you have a priced baseline to measure the change against.

In interior fit-out a BOQ typically spans civil work, flooring, false ceilings, partitions, joinery and loose furniture, electrical, HVAC, and plumbing — each as its own package of priced lines.

The interior fit-out BOQ format

A fit-out BOQ is a table with six columns. That’s it — the format is simple; the discipline is in filling it honestly.

#	Description	Unit	Qty	Rate (₹)	Amount (₹)
1	Gypsum partition wall	sqm	48	1,450	69,600
2	Vitrified tile flooring	sqm	120	1,180	1,41,600
3	Grid false ceiling	sqm	120	950	1,14,000
4	Modular workstations	nos	24	18,500	4,44,000
	Subtotal (works)				7,69,200

Reading the columns:

• # (serial no.) — every line is numbered so the client, the site team, and the invoice can all refer to the same item.
• Description — what the work is, specific enough to price and to inspect. “Gypsum partition wall,” not “partitions.”
• Unit — the unit of measurement: sqm for area, rft for running feet, nos for counts, lump only where a line genuinely can’t be measured.
• Qty — the quantity, taken off the drawings.
• Rate — the cost per unit, loaded with material, labour, wastage, and your margin. This column is where your margin lives or dies.
• Amount — rate × quantity. The lines sum to a works subtotal, on top of which you add overheads, contingency, and GST to reach the contract value.

How to build a BOQ for an interior project

1. Take off the quantities from the drawings. Measure each item to its natural unit. A wrong quantity here becomes a wrong price everywhere downstream, so this step earns the most care.
2. Group the lines by package — civil, flooring, ceiling, partitions, joinery, furniture, electrical, HVAC, plumbing. Grouping makes the BOQ readable for the client and easy to price against sub-contractor quotes.
3. Attach a unit rate to every line, pulled from your own rate library or current supplier quotes. Consistent, defensible rates are what separate a profitable BOQ from a hopeful one.
4. Multiply rate by quantity, then total. Sum the lines into a works subtotal; add overheads, contingency, and GST to reach the number the client signs.
5. Keep the priced BOQ live — which is exactly where most firms stop, and where the trouble starts.

Where a frozen BOQ quietly loses you money

Here’s the pattern that costs fit-out firms real money. The estimator builds a careful BOQ in Excel, the firm wins the job — and the BOQ is never opened again. The proposal is retyped from it. Variations get scribbled on WhatsApp and priced from memory. The final invoice is rebuilt from site notes. By handover, three documents that should be the same document have drifted apart, and nobody can say cleanly what was agreed versus what was built.

The leak isn’t dramatic. It’s a variation that was done but never billed. A rate that was discounted in the proposal but not in the costing. A subtotal that no longer matches because someone edited a cell. On a single ₹7-8 lakh fit-out it might be a percentage point or two; across a year of projects it’s the difference between a healthy margin and a thin one.

And notice what the fix is not. It isn’t a heavyweight project-management platform with Gantt charts and resource calendars. The leak is upstream of all that — it’s in the quote-to-cash chain: BOQ → proposal → variation → invoice. Fix that chain and you’ve fixed the part of fit-out that actually touches money.

From BOQ to billing: keep it live

The honest answer to “what BOQ software do I need?” is: software that keeps the BOQ live across that whole chain, so you only ever price a line once.

That’s the specific job Boqos does. You build the BOQ once; the client proposal is generated from those priced lines, every variation updates the same lines with an approval trail, and the invoice is produced from the BOQ-plus-approved-variations — not rebuilt from memory. Nothing is re-keyed, so nothing drifts, and at handover you can see exactly what was agreed, what changed, and what you actually made on the job. It’s deliberately a quote-to-cash tool, not a full PMS — the wedge where fit-out firms lose money quietly.

You don’t need that to start. You need a clean six-column BOQ and the discipline to keep it current. But once you’re running several fit-outs at a time, “keep it current by hand in Excel” stops being realistic — and that’s the point where keeping it live in software pays for itself.

The short version

A BOQ prices an interior fit-out line by line — six columns, rate × quantity, grouped by package. It’s simple to lay out and hard to keep honest. Build it carefully from the drawings, price every line from a real rate library, and — the part most firms skip — keep it live from quote to cash so the invoice still ties back to the number the client signed. That last step is where the margin you estimated either reaches your bank account or quietly disappears.
