★ SOSA for Indore Businesses
Neither, and the choice between them is the mistake - transaction value smuggles in a return nobody can evidence, decoration budget is the wrong shape for something that consumes a refill, and the only denominator that survives contact with reality is running cost per day

Is decoration budget a better denominator? No. Decoration is one-time capital and scenting is a small capital item plus an ongoing consumable, so the shapes do not match.
What should be used instead? Running cost per day, compared against things the business already pays for weekly without asking any of them for a return, such as fresh flowers.

Facts verified 9 September 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 roughly 75-90 days depending on intensity and run hours, Bluetooth app and onboard button control, 1h/4h/8h/24h timers, adjustable intensity, operation under 38dB, DC 12V/1A at 5W, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification - electrical and compliance marks only. Being waterless it adds no moisture and leaves no residue on paper, screens or documents; refill supply should be confirmed with SOSA. 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. The SOSA Sukoon (₹1,899) is a 500ml water-based ultrasonic diffuser for a single room of roughly 270-320 sq ft, and the SOSA Boond (₹899) is its compact equivalent; both use the water-based Hotel Collection fragrance (15ml from ₹299, 100ml ₹999, 300ml ₹1,799), which is made for ultrasonic diffusers and is not reed diffuser oil. SOSA reed diffusers - Morning Freshness (₹749 / ₹1,249) and Mountain Breeze (₹849 / ₹1,349), or the two together as the Fresh & Grounded duo (₹1,548 / ₹2,548) - are alcohol-free and phthalate-free, with a 50ml bottle lasting 6-8 weeks and a 130ml bottle 14-18 weeks. Ambient fragrance in a commercial space is an interior and hospitality decision only. SOSA makes no claim that it treats, relieves, prevents or improves any medical, dental or psychological condition, that it makes anyone feel calmer, more comfortable or more confident, that it affects recovery, patient comfort or any clinical outcome, or that it affects footfall, walk-ins, enquiries, bookings, conversions, sales, average spend, dwell time, customer retention or revenue. It does not remove or reduce any odour in the air, and it is never a substitute for ventilation, cleaning, housekeeping or fresh-air exchange - an office with a persistent smell has a source to find and fix first. Closed treatment rooms, consultation cabins and any closed one-to-one room are never scented, because the person inside cannot leave and did not choose to be there. A named seat away from the source is kept genuinely fragrance-free in the reception or waiting area and offered rather than waiting to be requested. The visitor's preference overrides any plan on this page, and where a customer, patient or member of staff is sensitive to fragrance the correct response is to reduce or switch off. 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.
Neither. Transaction value implies a return nobody can evidence. Decoration budget is the wrong shape for a consumable. Use rupees per day, beside the flowers.
Quick answers — read this first
Should experience spending be a percentage of transaction value? No. That framing assumes the spend earns a share of the transaction, which is a commercial-outcome claim nobody can evidence.Is decoration budget a better denominator? No. Decoration is one-time capital and scenting is a small capital item plus an ongoing consumable, so the shapes do not match.
What should be used instead? Running cost per day, compared against things the business already pays for weekly without asking any of them for a return, such as fresh flowers.
The short answer
Short answer: neither. Transaction value implies a return nobody can evidence and decoration budget is the wrong shape for a consumable, so the honest denominator is running cost per day beside the flowers and the newspapers.
The pick: a SOSA Vaayu (₹11,999) with a 400ml tank running roughly 75-90 days, or a SOSA Mountain Breeze Reed Diffuser (₹849) for 50ml over six to eight weeks.
Next step: ask your accounts team what the flowers cost per week. Or ask for a scenting plan for your space.

Straight answer
Should customer experience investment be calculated against transaction value or against the decoration budget?
Neither, and being asked to choose between them is the actual problem, because both denominators quietly assert something untrue. Take transaction value first, since it is the more attractive of the two. The logic runs: our average sale is large, therefore a small percentage of it justifies spending on the room. Read that sentence again and notice what it assumes. It assumes the room earns a share of the transaction. That is a commercial-outcome claim, and nobody - not SOSA, not any scenting company, not any interior designer - can evidence it. No study a business could run in its own showroom would separate the room from the product, the price, the person at the counter, the season, the gold rate or the fact that the customer's cousin got married in November. It also produces absurd arithmetic in both directions: a jeweller with lakh-rupee transactions can justify almost any spend on a small waiting area, while a busy business with modest transactions can justify almost nothing, even though far more people sit in its room. A denominator that scales with the wrong variable is worse than no denominator at all. Decoration budget fails differently, and more practically. Decoration is one-time capital: you buy the marble once and it is done. Scenting is a small capital item plus a consumable that recurs forever - a tank, a refill, an interval. Judging a consumable as a percentage of a one-time budget produces the single commonest failure in this industry: the machine is bought inside the fit-out, the refill is never budgeted, and eighteen months later there is an empty unit on a wall that the business paid for twice, once in money and once in the impression it now makes. So use the denominator that matches the shape of the thing. Running cost per day. A SOSA Vaayu at ₹11,999 written down over three years is roughly eleven rupees a day before refills, on a 400ml tank that runs about 75 to 90 days depending on intensity and run hours. A SOSA Mountain Breeze Reed Diffuser at ₹849 for 50ml over six to eight weeks lands in the same order of rupees per day. Now put that figure in the row where it belongs, which is not the capital row. It belongs beside the things the business already pays for every week and has never once asked to justify themselves: the fresh flowers at the entrance, the newspapers and magazines nobody finishes, the water for the cooler, the mat that is cleaned weekly, the lift contract. Nobody has ever asked the florist for a return, and nobody ever will. Which makes the decision rule short and genuinely usable. If it costs less per day than the flowers, it does not need a business case any more than the flowers did. If it costs more than the flowers, that is a real answer and the honest response may well be no - and no is a respectable outcome in this category. The number to keep watching afterwards is not a commercial one either: it is whether the refill interval matches the predicted one, and whether the level has drifted from where it was locked - which is the whole of an honest measurement list. Fragrance is an ambience decision like lighting or seating: it does not remove or reduce anything in the air, it treats nothing and relieves nothing, and SOSA makes no claim that it does, nor any claim about footfall, enquiries, conversion, retention or spend. Closed consultation cabins and one-to-one rooms are never scented. A named seat away from the source is kept genuinely fragrance-free and offered rather than requested. It works alongside ventilation, cleaning and housekeeping, never instead of them, and the visitor's preference overrides any plan. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.

A connected reception, waiting area and corridor of ~1,500-3,000 sq ft
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - about 2,000-3,000 sq ft - on one unit. In a clinic, showroom or office its value is control rather than reach: the key-lock holds the level the furthest waiting chair was judged to, so it survives every shift and every new receptionist, and the 1h/4h/8h/24h timer keeps it on opening hours rather than saturating an empty room overnight. Waterless, so it adds no moisture and leaves no residue on stock, mirrors, screens or displays. 400ml tank, roughly 75-90 days depending on intensity and run hours, under 38dB, wall or HVAC mount.

The register - or the whole answer where reception is one seating zone
SOSA Mountain Breeze Reed Diffuser
Himalayan pine, sage and Indian cedar - the driest register SOSA makes and the house default, because it reads as a considered room rather than as a hotel lobby. Where reception is a single seating group, this bottle at the staff end of the desk at ₹849 for 50ml carries the register on its own, three or four reeds in, flipped weekly; 130ml at ₹1,349 lasts 14-18 weeks. Alcohol-free, phthalate-free, six fibre reeds, and carried out of the room in seconds if a client asks.
From ₹849
Two wrong denominators and one workable one
Each framing carries an assumption. Only one of the three survives being said out loud.
1
Wrong one
Transaction value assumes a return
A percentage of the sale implies the room earns a share of the sale. That is a commercial-outcome claim, and no business could separate the room from the product, the price, the person or the season.
Rule: the arithmetic smuggles in the claim.
2
And it scales badly
It sizes by the wrong variable
Lakh-rupee transactions justify almost any spend on a small waiting area, while a much busier business with modest transactions justifies almost nothing. The rooms are the wrong way round.
Test: a bad denominator is worse than none.
3
Wrong two
Decoration is a one-time shape
You buy marble once. Scenting is a small capital item plus a consumable with an interval, so a percentage of a capital budget describes the wrong object entirely.
Rule: shapes have to match.
4
The failure
The machine nobody refills
Bought inside the fit-out, never budgeted afterwards, and eighteen months later an empty unit on a wall the business paid for twice - once in money and once in the impression it now makes.
Test: budget the refill or do not buy the machine.
5
The right one
Rupees per day, beside the flowers
A machine at ₹11,999 over three years is roughly eleven rupees a day before refills. Put that beside the florist's bill, the newspapers, the water and the weekly mat clean.
Rule: cheaper than the flowers needs no business case.
The SOSA principle
Nobody has ever asked the florist for a return. Put the daily figure in that row rather than in the capital row, and the decision either answers itself or turns into an honest no.
Both of the denominators in the question fail before the arithmetic starts: one asserts a commercial outcome nobody can evidence, the other describes a one-time object that this is not.

How to size an ambience decision
| The question | The answer |
|---|---|
|
Should it be a percentage of transaction value?
|
No. That assumes the room earns a share of the sale, which is a commercial-outcome claim that no business could evidence in its own showroom. |
|
Should it be a percentage of the decoration budget?
|
No. Decoration is one-time capital; this is a small capital item plus a consumable with an interval, so the shapes do not match. |
|
What goes wrong when the shapes do not match?
|
The refill is never budgeted. Eighteen months later there is an empty unit on a wall that the business has paid for twice. |
|
What is the right denominator?
|
Running cost per day, compared against the weekly items nobody audits: the flowers, the newspapers, the water and the mat cleaned every week. |
|
What does that come to?
|
A Vaayu at ₹11,999 over three years is roughly eleven rupees a day before refills; a reed at ₹849 lasts six to eight weeks. |
The objection version is they already buy from us, the metric version is what to measure afterwards, and the high-value version is a crore vehicle against a small machine. SOSA makes no claim about footfall, enquiries, conversion, retention or spend.
One register, the visitor-facing zone only, set from the furthest seat
SOSA Vaayu ₹11,999 waterless, key-locked and timed to opening hours; Mountain Breeze ₹849 or Morning Freshness ₹749 as the register. Send the floor plan with the closed rooms and the entrance marked and we will return it with the placement and the fragrance-free seat.
A percentage of transaction value is not a budgeting method. It is a commercial-outcome claim wearing the clothes of arithmetic, and it should be refused in that form.

 SOSA Boond
|
A director's cabin, a small reception or a single desk | One small enclosed space only, on low; never in a closed treatment room or consultation cabin | ₹899 View → |
A SOSA Sukoon (₹1,899) is the water-based rung for a single enclosed reception or client lounge of roughly 270-320 sq ft in a dry room, and a Boond (₹899) for a single cabin; both run on the water-based Hotel Collection fragrance (from ₹299), which is not reed diffuser oil and is not interchangeable with it. Above about 3,000 sq ft of one connected volume the step is one SOSA Angaan (₹25,999) on the duct, not a second Vaayu. Closed treatment rooms, consultation cabins and any closed one-to-one room are never scented - the person inside cannot leave and did not choose to be there - and that is achieved by placement and doors rather than by a lower setting. A named seat away from the source is kept genuinely fragrance-free and offered at the desk rather than waiting to be asked. Fragrance is an ambience decision like lighting or seating: it does not remove or reduce anything in the air, it treats nothing and relieves nothing, it makes no contribution to what a visitor buys, books or decides, and it works alongside ventilation, cleaning and housekeeping, never instead of them. The visitor's preference overrides any plan. Ask for a scenting plan for your space and send the floor plan with the closed rooms and the entrance marked.

A SOSA Vaayu at ₹11,999 written down over three years is roughly eleven rupees a day before refills, on a 400ml tank running about 75 to 90 days depending on intensity and hours; a SOSA Mountain Breeze Reed Diffuser at ₹849 for 50ml over six to eight weeks is the same order.

Frequently asked questions
Should ambience spending be a percentage of transaction value?
No. That framing assumes the room earns a share of the sale, which is a commercial-outcome claim that no business could evidence.
Why is the decoration budget the wrong denominator?
Because decoration is one-time capital and this is a small capital item plus a consumable, so a percentage of capex describes the wrong object.
What happens when the refill is not budgeted?
The machine empties and stays on the wall. The business has then paid twice, once in money and once in the impression an empty unit makes.
What is the correct way to size it?
Running cost per day, set beside the weekly items nobody audits: the flowers at the entrance, the newspapers, the water and the mat clean.
What does that work out to?
A ₹11,999 machine over three years is roughly eleven rupees a day before refills, and a ₹849 reed diffuser lasts six to eight weeks.
Ask what the flowers cost per week
SOSA — Studio Scenting rupees per day
Transaction value assumes the room earns a share of the sale, which is a commercial-outcome claim nobody can evidence, and it sizes by the wrong variable in both directions. Decoration budget is a one-time shape applied to something with a refill, which is how businesses end up with an empty unit on a wall. Use rupees per day instead, and put the figure beside the flowers, the newspapers and the weekly mat clean. Cheaper than the flowers needs no business case. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
