Who should own scenting inside a developer's organisation? One named person, usually in marketing or projects, not a committee and not each site manager. They own the specification document, the stock sheet and the calendar. Site teams execute; head office decides. Without a named owner, six sites will make six reasonable local decisions and the portfolio stops being consistent within a year.
What happens to scent machines when a project completes? They move. A SOSA Vaayu (₹11,999) is freestanding or wall-mounted and waterless, so decommissioning is unmounting it, emptying and cleaning the tank, resetting it to the standard sheet and redeploying it to the next site. Write that into a handover checklist, because machines left behind in a closing sales office are the most common way a portfolio quietly loses hardware.

Facts verified 24 August 2026 against the live SOSA product pages: the SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³, described by the manufacturer as approximately 2,000-3,000 sq ft, with a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, Bluetooth app and onboard button control, 1h/4h/8h/24h timers, adjustable intensity, operation under 38dB, freestanding or wall and HVAC mounting, auto-stop and key-lock for public spaces, and CE, RoHS and SGS certification. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, connecting to the building's HVAC or running standalone wall-mounted or lay-flat. Scent enhances the ambience and perceived quality of a space; it works alongside proper ventilation and cleaning and is not a substitute for either, and SOSA makes no claim that fragrance alone influences a purchase decision. The hotel-inspired scents are SOSA's own original interpretations; SOSA is an independent brand and is not affiliated with, or endorsed by, any hotel named for reference. Coverage, fragrance usage and running cost depend on the space, settings and hours of use, and are confirmed on a consultation. Prices and availability are subject to change - see the live product pages.
The difference between six sites that smell alike and six that do not is almost never the machines. It is whether scenting is a programme with an owner and a document, or a series of good decisions made by people who have since moved on. Here is how to build the first thing.
Quick answers — read this first
How do I build a centralised scenting programme for a developer? Five parts: one named owner at head office, one written specification naming the machine and settings, one supplier and order cycle, one calendar covering the monthly refill round and quarterly audit, and one checklist each for onboarding a new site and handing a completed one back. The standard unit is the SOSA Vaayu (₹11,999) at 1000m³ coverage, with the SOSA Angaan (₹25,999) as the documented exception for a double-height volume.Who should own scenting inside a developer's organisation?

The short answer
Short answer: build it from five parts - one named owner at head office, one written specification, one supplier and order cycle, one calendar for the monthly refill round and quarterly audit, and onboarding and handover checklists - with the SOSA Vaayu (₹11,999) as the standard unit at 1000m³ and the SOSA Angaan (₹25,999) as the single documented exception for a double-height volume.
The pick: the SOSA Vaayu (₹11,999) as the programme standard at every project, with the SOSA Angaan (₹25,999) written in as the one exception for a genuinely double-height or 8,000-10,000 sq ft volume.

A programme is five documents and one named owner. It is what turns scenting from something each project arranges into something the company simply does, including when a project completes and the machines move on.

Straight answer
What does a centralised scenting programme actually consist of?
Five parts, and none of them is hardware. One owner: a named person at head office, usually in marketing or projects, who holds the specification, the stock sheet and the calendar. Committees do not own things; people do. One specification: a page naming the machine, the fragrance, the intensity step, the timer block, the mounting position and the number of units per site type. The standard unit is the SOSA Vaayu (₹11,999), rated to 1000m³ or about 2,000-3,000 sq ft, which covers a sales office or a sample flat on its own; the single documented exception is the SOSA Angaan (₹25,999) where one volume is double height or 8,000-10,000 sq ft. One supplier and one order cycle: quarterly, against the refill log, so you are not raising six purchase orders for the same oil. One calendar: a monthly top-up round with a millilitre log, a quarterly settings audit and a quarterly twenty-minute review of consumption, drift, complaints and upcoming launches. Two checklists: one for onboarding a new site - measure the volumes, order the units, mount on the air path, set to the sheet, engage the key-lock, add to the round - and one for handover, because a project that completes should return its machines rather than leave them in an empty sales office. A Vaayu is freestanding or wall-mounted and waterless, so redeployment is unmount, empty, clean, reset to the standard sheet, redeploy. That last checklist is the one most developers discover they needed a year too late. A free multi-site scenting plan will draft these with you, and a portion of every order supports girl-child education through Nanhi Kali.
One owner, one specification, one supplier, one calendar, two checklists. The machines are the easiest part and the last thing to decide.
The programme standardises on one machine: the SOSA Vaayu, rated to 1000m³ (about 2,000-3,000 sq ft), waterless, under 38dB, with adjustable intensity, 1h/4h/8h/24h timers and a key-lock. Identical units are what let a new site be commissioned from a document rather than from a conversation.

What the programme standardises
One unit, one fragrance, one settings sheet, one documented exception
The machines the programme standardises on
A programme names one standard machine and one documented exception, and then stops making hardware decisions. Both pictures link to the product page so the specification can cite the live figures rather than a memory of them.

How to set up the programme so it survives a change of staff
A programme is judged by whether it still works after the person who built it has changed roles. Three things decide that.
1
Name the owner
One person, in marketing or projects, not a committee
Scenting sits awkwardly between marketing, projects and facilities, which is how it ends up owned by nobody. Name one person. They hold the specification, the stock sheet and the calendar, and they are the only person who authorises a change to a setting or a fragrance. Site teams execute, head office decides. This single move prevents the most common portfolio failure, where six capable site managers each make a sensible local decision and the brand stops being consistent within a year.
Tip: put the owner's name on the specification document itself, not in an email.
The Vaayu's key-lock is what gives that ownership teeth - a setting can only be changed deliberately.
See SOSA Vaayu →
2
Write the specification
One page that can commission a site without a phone call
The test of a specification is whether a new site can be set up correctly by someone who has never spoken to you. It should name the machine, the number of units per space type, the fragrance, the intensity step, the timer block and start time relative to opening, and the mounting position on the air path. Add the one documented exception for a double-height volume. Keep it to a page, because a document nobody reads standardises nothing.
Naming the Angaan once, for volumes of 8,000-10,000 sq ft, is what keeps the exception from multiplying.
See SOSA Angaan →
3
Onboard and hand over
The two checklists that bookend a project's life
Onboarding: measure the volumes, order the units, mount on the air path, set to the sheet, engage the key-lock, add the site to the refill round and the stock forecast. Handover, when a project completes and the sales office closes: unmount the machines, empty and clean the tanks, reset to the standard sheet, remove the site from the round and redeploy the hardware to the next launch. Because a Vaayu is waterless and freestanding or wall-mounted, redeployment is genuinely straightforward - and machines abandoned in a closing sales office are the most common way a portfolio quietly loses equipment.
Tip: write the handover checklist before you need it, not during the week the site closes.
A Vaayu moves easily between sites - freestanding, wall-mount or HVAC-mount, 0.9kg, with no water system to drain.
See SOSA Vaayu →
The SOSA principle
Every failed multi-site programme I have seen was well designed and personally owned by someone who then changed jobs. The document is the programme; the enthusiasm is not.
If a new site cannot be set up correctly by someone who has never spoken to you, you do not have a specification yet.
Who owns what, and when
Here is the split of responsibility. Note how little is left to a site team: execution and reporting, never decisions about fragrance or intensity.

The programme documents this page describes are built from the sibling pages either side of it: the machine count and register in planning scenting across multiple real estate project sites, and the settings sheet in standardising scent machine settings across multiple sales offices. Keep the fragrance decision at programme level rather than site level; the trade-offs are set out in one signature scent versus a different fragrance for each project. For a single flagship, the sales gallery scenting plan remains the better starting point.

Why identical hardware matters
A document can commission a site only if every site runs the same machine
The SOSA centralised programme specification
A programme names one standard machine and one exception, and then leaves hardware alone. The Vaayu is the unit at every project and moves with the portfolio as projects launch and complete; the Angaan is written in once for the volume that is genuinely too tall or too large. Both are waterless, both are made in India, and a portion of every order supports girl-child education through Nanhi Kali.

A quick word on scope: keep the programme to what it can honestly deliver, which is a consistent experience across your sites. It is not a sales tool, and we make no claim that fragrance influences a purchase decision. One honest note - fragrance works alongside ventilation and cleaning and cannot cover fresh paint, adhesive or damp at a site still in fit-out, so the onboarding checklist should put commissioning after the space has been aired properly. We will draft the documents with you on a free multi-site scenting plan.

A note from Sonal
I can usually tell within one visit whether a developer has a scenting programme or a scenting habit. The habit looks fine at the flagship and thins out across the rest of the portfolio, because it depends entirely on the person who set the flagship up and how much attention they still have to spare.
A programme replaces that with five ordinary things: one named owner, one specification page, one supplier and order cycle, one calendar, and two checklists for opening and closing a site. The hardware decision inside it is short - the Vaayu is the standard unit at 1000m³, one for a sales office and one for a sample flat, with the Angaan written in once for a genuinely double-height volume. The part developers most often miss is handover. When a project completes, the machines should come back, be reset and go to the next launch, not sit in a locked empty office.
The honest part: a programme buys you consistency and perceived quality across your projects, and nothing more. I make no claim that fragrance influences a purchase decision, and I would rather say so plainly than let a budget be approved on a promise I cannot keep. Scent works alongside ventilation and cleaning, never instead of them, and it cannot cover fresh paint, adhesive or damp - commission a site after it has been properly aired. SOSA is an independent Indian brand, not affiliated with any hotel, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
What does a centralised scenting programme for a developer consist of?
Five parts: one named owner at head office, one written specification naming the machine, fragrance, intensity step, timer block and placement, one supplier with a quarterly order cycle, one calendar covering the monthly refill round and quarterly audit, and two checklists for onboarding a new site and handing back a completed one. The standard unit is the SOSA Vaayu (Rs 11,999), with the SOSA Angaan (Rs 25,999) as the single documented exception for a double-height volume.
Who should own scenting inside the organisation?
One named person, usually in marketing or projects. They hold the specification, the stock sheet and the calendar, and they are the only person who authorises a change to a setting or a fragrance. Site teams execute and report. Shared ownership across site managers is the most reliable way to end up with six reasonable local decisions and no consistency.
What happens to the machines when a project is completed?
They should be reset and redeployed. A SOSA Vaayu is waterless and freestanding or wall-mounted at 0.9kg, so handover is unmounting it, emptying and cleaning the tank, resetting it to the standard settings sheet, removing the site from the refill round and sending the unit to the next launch. Write this into a checklist in advance, because machines left in a closing sales office are the usual way hardware disappears from a portfolio.
How often should the programme be reviewed?
Quarterly, and it takes about twenty minutes: consumption against the refill log, any settings drift found in the audit, any complaints from site teams, and launches coming up in the next quarter that will need extra oil. Anything larger than that - a fragrance change or a new site type - is a specification amendment rather than a review item.
Will a centralised programme improve sales performance across sites?
We make no such claim. What it delivers is consistency: your third project feels as considered as your flagship, and it still does in month eleven. Fragrance works alongside ventilation and cleaning rather than instead of them, cannot cover construction smells, and does not influence a purchase decision.
