Does a bigger home cost more per square foot? Less. Cost follows doors rather than area, and a large home has proportionally more space - circulation, service areas, terraces - that needs nothing at all.
What is the ongoing cost? Reeds are consumed by time rather than use, at roughly Rs 200 to Rs 280 per room per month. Machine consumption depends on the run schedule and is quoted against the actual setup.
It scales with doors, so cost per square foot falls
The cost of this layer behaves in a way that surprises clients, and it is worth setting it out openly because the surprise runs in their favour and because a designer who explains it clearly is trusted on the rest of the specification. The governing fact is that cost scales with the number of rooms and doors rather than with floor area. A machine distributes fragrance through connected moving air and cannot cross a closed door, so a plan divides into zones bounded by the doors that stay shut. Each connected zone takes one machine, and each closed room takes a reed. Neither of those quantities has anything to do with square footage. Here is the arithmetic. Machines: the Vaayu at Rs 11,999 for a large connected volume - waterless with no tank, coverage up to 1,000 square metres or roughly 10,700 square feet, with Bluetooth app and timer control; the Megh at Rs 3,499 with a 6L tank for a substantial area; the Sukoon at Rs 1,799 for a single room; the Boond at Rs 799 for a small one. Reeds: Garden Bloom and Evening Calm at Rs 799, Morning Freshness at Rs 749, Fresh Brew and Mountain Breeze at Rs 849, each including the bottle and reeds. Fragrance for machines: the seven Hotel Collection registers at Rs 299 for 15ml, Rs 999 for 100ml and Rs 1,799 for 300ml, used at three to six drops per tank. So a large villa with a connected living volume and twelve rooms behind closed doors is one machine and twelve reeds, and the machine is the smaller half of the conversation in most large homes rather than the larger one. Now the part clients do not expect: in a large home a great deal of the floor area receives nothing at all, deliberately. Circulation between scented rooms needs no source of its own, because it takes what the connected zones give it. Staff quarters, utility rooms, stores and service corridors get nothing, as a rule rather than as an economy. Covered verandahs, loggias, balconies and terraces cannot hold fragrance at all, because the air is not enclosed and it disperses as fast as it is produced - so however much of a villa is covered outdoor area, and it is often a lot, none of it is in the specification. And the kitchen is never scented, at any time, because cooking smell is aerosolised oil and the answer is extraction. Add all of that up and the proportion of a large home that is actually specified is smaller than the proportion of a small one, which is why the cost per square foot falls as houses get bigger. A 1,200 square foot two-bedroom flat and a 6,000 square foot villa do not differ by a factor of five in this line item. Then the running cost, which should be stated in the proposal even though clients rarely ask, because discovering an ongoing cost after handover feels like something was concealed however small it is. Reeds last three to four months a bottle, with refills at Rs 2,399 for 300ml and Rs 3,499 for 500ml, which works out at roughly Rs 200 to Rs 280 per room per month. Two things about that number matter. First, it is per room rather than per square foot, so it too scales with doors. Second, reeds are consumed by time rather than by use, which means a formal drawing room opened twice a month costs exactly what a bedroom used every night costs, and a guest room used ten nights a year costs the same again. Clients frequently assume the opposite, and it is better said upfront than discovered in month four. On machine consumption we are deliberately unhelpful, and it is worth explaining why rather than inventing a figure: how much fragrance a machine uses depends entirely on its run schedule, the size of the volume and the level it is set to, and any millilitres-per-month number we printed would describe our assumptions rather than a particular home. We quote against the actual setup instead. A designer can put that sentence into a proposal verbatim, and it reads as accuracy rather than evasion. Two commercial notes for the practice. All three charging models work - pass the cost through at supply price with your specification time inside the design fee, take a stated markup as you would on FF&E, or charge a specification fee and let the client buy directly - and what matters is that the model is disclosed at the start rather than discovered. In a premium project the client will eventually see supply pricing, and a markup disclosed at the outset is a commercial arrangement while the identical markup discovered later costs far more than the margin was worth. And because fragrance is a consumable rather than a fixture, decide deliberately whether you want a continuing role after handover or a clean exit; most practices, once they think it through, want the exit, which points at pass-through with a reorder path written into the handover pack. Finally, the way to present the number. Price it room by room in the schedule rather than as a lump sum at the bottom of a page. A reed at Rs 749 against a bedroom line is a small approvable figure that a client barely pauses on, while the same money aggregated reads as a negotiable lump. Room-by-room is also the more truthful presentation, because it lets a client remove the guest bedroom and keep the master, which is exactly the sort of editing they should be able to do. And write the exclusions in as excluded rather than absent - kitchen, children's rooms, covered terraces, staff and utility areas - because a specifier who declines to sell several rooms is visibly not selling, which is what makes the rest of the schedule credible. One register throughout, varied by intensity, because two registers meet in doorways and the collision reads as something being wrong. SOSA is independent and not affiliated with, endorsed by or associated with any hotel brand, and we make no claim that fragrance affects mood, focus, sleep, stress or wellbeing. Everything is alcohol-free and made to IFRA-compliant standards, and a portion of every order supports girl-child education through Nanhi Kali. Volume pricing across a large project is quoted against the specification on WhatsApp.
The arithmetic, stated openly
This cost scales with doors rather than floor area, which means cost per square foot falls as a house gets bigger. A machine cannot cross a closed door, so a plan divides into zones: each connected zone takes one machine and each closed room takes a reed, and neither quantity relates to square footage. The arithmetic: the SOSA Vaayu at Rs 11,999 for a large connected volume, waterless with coverage to 1,000 m² and app and timer control; the SOSA Megh at Rs 3,499 with a 6L tank; the SOSA Sukoon at Rs 1,799; the SOSA Boond at Rs 799. Reeds at Rs 749 to Rs 849 each. Hotel Collection at Rs 299 for 15ml, Rs 999 for 100ml and Rs 1,799 for 300ml, used at three to six drops per tank. So a large villa with one connected volume and twelve closed rooms is one machine and twelve reeds, and the machine is usually the smaller half of the conversation. In a large home a great deal of floor area receives nothing deliberately: circulation takes what the zones give it, staff quarters and utility get nothing as a rule, covered verandahs and terraces cannot hold fragrance at all, and the kitchen is never scented. So the specified proportion of a big house is smaller than that of a small one. The running cost belongs in the proposal even though clients rarely ask: reeds last three to four months, refills at Rs 2,399 for 300ml and Rs 3,499 for 500ml, roughly Rs 200 to Rs 280 per room per month - per room rather than per square foot, and consumed by time rather than use, so a formal room opened twice a month costs what a nightly bedroom costs. On machine consumption we are deliberately unhelpful and say why: it depends on run schedule, volume and level, and any printed millilitres-per-month figure would describe our assumptions rather than a particular home, so we quote against the actual setup. Commercially, all three models work - pass-through with your time in the design fee, a stated markup as on FF&E, or a specification fee - and what matters is disclosure at the start, because a markup discovered later costs more than the margin was worth. And since fragrance is a consumable, decide deliberately between a continuing role and a clean exit; most practices want the exit, which points at pass-through with a reorder path in the handover pack. Present it room by room rather than as a lump sum, because a reed at Rs 749 against a bedroom line is approvable while the same money aggregated invites negotiation, and write the exclusions in as excluded. One register throughout, varied by intensity. Everything is alcohol-free and made to IFRA-compliant standards. Volume pricing is quoted on WhatsApp.

Every SOSA fragrance is alcohol-free and made in India, and a portion of every order supports girl-child education through Nanhi Kali - so every customer gift quietly gives twice. Here is the full business range by per-unit band.

Versailles
Most customer gifts are bought to be handed over, not to be kept: the sweet box is finished by the family that evening, the keychain joins a drawer, the branded pen was never really a gift at all. Then the moment that cost your business lakhs to create - the new car, the new home, the big purchase - is remembered with nothing. A fragrance gift keeps that moment alive, because scent is the sense wired closest to memory: months later, your customer is still in the middle of the experience you gave them.
I trained at ISIPCA in Versailles and everything we make is built for Indian lives - car diffusers that survive a Mumbai summer, reed diffusers that hold through the monsoon, alcohol-free formulas safe to gift across every customer profile. If you run a dealership, a project, a hotel, a showroom or a team, message the bulk desk on WhatsApp at +91 96192 18531 - tell me the customer moment and the volumes, and I will help you design the programme myself. The business conversations are my favourite kind: one good gifting programme teaches me more about a category than a year of retail orders.
And a part of every order funds girl-child education through Nanhi Kali - so your customer gift quietly gives twice. That equation has always felt right to me.
Frequently asked questions
Facts verified August 2026: Olfactory memory research shows scent-linked memories are unusually durable and emotionally vivid, which is why a used-daily fragrance gift sustains brand association in a way consumable or novelty gifts do not; customer-experience research consistently finds that peak moments (delivery, possession, checkout) disproportionately shape how the whole purchase is remembered. Fragrance preference is personal: volume gifting programmes should default to gentle fresh, green and lightly floral registers, and to space formats (diffusers, reeds, car fragrance) rather than skin perfume. SOSA range: Hotel Collection ultrasonic fragrance from Rs 299; car perfumes from Rs 449 (spray and hanging, alcohol-free); attars Nawaab, Ameeri, Mastani and Adaa from Rs 379 (3ml/6ml/12ml, alcohol-free); Attar Trio from Rs 1,055; perfumes from Rs 499; reed diffusers from Rs 749; Boond Rs 799, Sukoon Rs 1,799 and Megh Rs 3,499 ultrasonic diffusers; SOSA Safar waterless car and travel diffuser Rs 3,999 (rechargeable, three hotel-inspired scents included); SOSA Vaayu waterless scent machine Rs 11,999 (~1000m³, app + timer).
