The operator opens a round
One service, one society, a deadline, and a price ladder negotiated with a vendor: ₹1,000 alone, ₹800 at 5 ACs, ₹700 at 10.
You pledge what you need
Two ACs, three rooms, one 25 kg pack. One tap, and an SMS confirms it. Change or leave any time before the deadline.
Neighbours join, the price drops
Every pledge moves the ladder for everyone. Share the round to the society group with one tap; the people you bring in lower your own price.
The deadline closes it, a person books it
At the deadline the round closes on its own. The operator assigns the vendor at the unlocked price, the job gets done, and you rate it.
Your whole society, one price.
Bulk Saving pools what your neighbours already need, from AC servicing to a 25 kg pack of rice, and books it as one job. The more flats join, the less everyone pays. You tap once.

What Bulk Saving is, in one go
A demand-aggregation platform for home services, scoped to one housing society at a time. Neighbours pool what they already need; a negotiated vendor does it as one job; everyone pays the bulk price.
- 1
Neighbours pool
A round opens for one service in one society with a deadline. Residents pledge units in one tap: 2 ACs, 3 rooms, one 25 kg bag.
- 2
The price drops
Thresholds count units. Every pledge moves everyone down the ladder: ₹1,000 alone, ₹800 at five, ₹700 at ten.
- 3
One job, one visit
At the deadline the round closes itself. The operator books a rated vendor at the unlocked price; residents rate the work.

4.0+out of 5: the delivered-job rating the pilot must average, the bar every vendor is measured against
Cheaper, trusted, zero organising
- Pay the pooled price, not the single-customer price: about ₹300 less on a ₹1,000 AC service.
- One tap to join; the deadline and the vendor are handled.
- A rating on every job keeps vendors honest.
A service the committee can offer
- An invite code brings every flat in; every price is the society’s own.
- Pooled demand gets one vendor visit instead of forty, and one delivery to the gate for staples.
- Nothing to run: the operator opens rounds and books the work.
Ten jobs at one address
- No per-job acquisition cost, no scattered travel: a filled round is a day’s work in one building.
- A negotiated price for guaranteed volume.
- Ratings build a track record that wins the next round.
Demand first, supply by negotiation
- Residents signal demand before anyone buys; the operator negotiates with that number in hand.
- A commission on each pooled job; no inventory, no payment risk in the pilot.
- Defensibility is execution: vendor relationships, ratings, and recurring plans.
Why it holds
The discount is real economics.
Pooling removes the vendor's per-job acquisition and travel cost. The lower price is not a subsidy.
Demand before supply.
Residents ask and pledge before anyone buys; the operator negotiates with a number, not a hope.
Trust is measured.
Every delivered job is rated by the people who paid for it; vendors earn the next round.
Built to multiply.
Multi-tenant from the first line: a new society is an invite code; a new service is a row, not a release.
How a group buy works
A round is a shared deadline and a price that falls as neighbours join.
Group-buy rounds
A round is a time-boxed group buy for one service in your society. You join with the number of units you need, and everyone pays the best price the pooled units have reached.
Thresholds count units, not people, so one flat with three ACs moves the group as much as three flats.
A price ladder you can see
Each round shows every tier, where the count is now, and how many more units unlock the next price. A live countdown runs inside the last day, and one tap shares the round with neighbours.
The more neighbours join, the cheaper it gets for everyone. That has to be seen, not read in a footnote.
Deadlines that mean it
Rounds close themselves at the deadline. If the minimum tier was reached, the round goes to the operator for a vendor; if not, everyone is told it expired.
A deadline only creates urgency when the system keeps it without anyone watching the clock.
Units in the service’s own words
You pledge 2 rooms for deep cleaning, 3 ACs for servicing, or one 25 kg pack of rice. Every count on screen uses the service’s own noun.
“2 units” is abstract and causes mistakes; “2 rooms” is a pledge you can trust.
Browse, ask, book
Every service in your society, one tap from a pledge. No open round yet? Ask.

A catalog for your society
Services shows what is offered to your society, with an indicative price and what the job covers.
One society’s deal never leaks into another’s.
From a service to booking in one tap
A service with an open round shows it on its card: today’s price, units joined, when it closes. Tapping the card opens that round with the pledge sheet already up.
Sessions last about thirty seconds. Every extra screen between intent and pledge loses a neighbour.
Ask for this service
No round open? Tap Ask for this and see how many neighbours already asked. When the operator opens a round, everyone who asked hears first.
Asking turns invisible intent into a number the operator can act on, and rewards the askers with first notice.
Twenty-three services across six categories
Appliances, home care, renovation, utilities, vehicle care and bulk staples. The operator switches each one on per society and sets its price.
A catalog the operator cannot shape is not a product.
Never miss a round
You hear about every step by SMS and, on an installed phone, by push.
- You're in: 2 ACs in the AC servicing round at Blue Waters. 6 of 10 so far, ₹800 each. Closes Thu.
- Closing tomorrow: AC servicing at Blue Waters. 9 of 10 ACs, ₹800 now. One more unlocks ₹700 for everyone.
- Closed and met: 11 ACs at ₹700 each. The operator is booking the vendor.
- Vendor scheduled: CoolCare, Sat 10 am to 2 pm. Pay ₹1,400 to the technician after the job.
- Delivered. How did it go? Rate it in My Requests.
- A round opened for pest control at Blue Waters, which you asked for. ₹1,200 now, ₹950 at 8 flats.
An SMS for every step
Pledge confirmed, closing soon, closed with the final price, vendor assigned, job delivered, round cancelled. Nothing to set up.
Each message is written in the same database transaction as the event, so you never get one for something that did not happen, and never get it twice.
Push notifications in your colour
On an installed phone, a push arrives written for the event and tinted in the accent you chose. Tapping it opens the right round.
Bursts of hundreds of devices are sent by parallel workers that retry safely, never double-send and prune dead devices on their own.
Trust and accountability
A person negotiates every deal. A rating follows every job.
A person negotiates every deal
When a round closes met, the operator picks the vendor, records the negotiated price, marks the job delivered and tracks who has paid. Payment stays between you and the vendor.
Pooled demand is only worth something once someone turns it into a real job.
Rate every delivered job
After delivery, every participant rates the job from 1 to 5 with an optional note. You can correct a mis-tap.
The moment we recommend a vendor, a bad job is on us. Ratings attach to the round, so a vendor’s score is the honest sum of the jobs they did.
Ratings the operator can see
You rate from My Requests; the operator sees each vendor’s average and each round’s score.
The number has to be in front of the person who chooses the next vendor.
A confirm before anything you cannot undo
Leaving a round, removing a rating, withdrawing an ask or logging out all ask once first, and say so honestly if you are offline.
A mis-tap must never cost a neighbour their place in a round.
Built for a phone in a society
No passwords, no app store, no re-login. Works when the signal drops.
Your society code and your phone
Enter the invite code your society gave you and your number. A one-time code arrives by SMS and you are in. Everything you see is scoped to your society.
In a society the phone is the identity. Codes live in memory with a time limit and are never logged or shown.
Sign in with WhatsApp
Tap Continue with WhatsApp, send the message it opens, tap the number you see on screen, and you are back in the app, signed in. On a laptop, scan a QR code with your phone. The SMS code stays as the fallback.
WhatsApp already verified your number, and a message you start costs nothing. Three taps, nothing to type.
Sign in once per phone
After the first code, this phone stays signed in. You can end a session from Profile.
You use this before summer and once a quarter. Being asked for a code every time kills a thirty-second visit.
Add it to your home screen
Installs from the browser with no app store. A thumb-reachable bar for Home, Services, My Requests and Profile. When the signal drops it says so and shows what is stale.
A lost signal mid-round must never look like your round disappeared.
Home opens on what you can save today
The first screen shows how many rounds are open and the three closing soonest, each one tap from its pledge sheet.
The first screen should answer the only question you came with.
Feels like an app, not a page
Bottom sheets for pledging and rating, large titles that tuck into a blurred bar as you scroll, safe-area aware, and a night mode that reveals itself in a circle from the switch.
A page that feels like a website gets ignored; one that feels native gets installed.
A separate door for the operator
The operator signs in on their own page with a phone number alone, with its own rate limits.
Operators have no society invite code, and their door should not share a resident’s.
A look you want to open
Flat, quiet and precise, in your colour, day and night.
These switches change this page the way Appearance changes the app. Your choice is remembered on this device.
Flat paper, hairlines, Geist
Surfaces are paper with a one-pixel line. Corners are tight. The primary button is ink by day and near-white by night.
Calm and precise reads as trustworthy. Nothing glows that does not need to.
Seven colour pairs, one look
Pick mono, ocean, aurora, bloom, sunset, forest or lagoon. The geometry never changes; only the accent does. Small sparks mark a saving unlocked, and all of it stops if your phone asks for less motion.
Choice without losing coherence.
One set of tokens under everything
Colour, radius and type are variables, and every text-on-surface pair is tested for contrast in light and dark.
This site and the app share the same token sheet, pinned by a test, so what you see here is what you get.
Search and filters that stick
Search any list by name, filter by category or status. The filter lives in the address, so a refresh or a shared link keeps it.
A catalog of twenty-three services and lists across societies need real search.
For the people who run it
One dashboard turns pooled demand into a real job and tracks who has paid.
What the operator does
Sees demand across societies, opens rounds, negotiates with vendors offline, assigns the job at the unlocked price, marks it delivered, and ticks off each flat's payment. Manages the catalog per society and a short vendor list. Lean by design: a phone, this dashboard, and vendor relationships that compound.
Lists that stay fast
Every list loads a page at a time with an explicit Show more, across societies and rounds.
Nothing is silently cut off as the number of societies grows.
A pilot: bulk staples
The same round, for a single product in a fixed pack, delivered once to the gate.
If ten flats want the same pack in the same week, a wholesaler delivers once and everyone pays less. No baskets, no fresh produce, no delivery slots: one product, one pack, one drop. We are testing whether staples rounds fill the way service rounds do.
What one society is worth
Move the sliders. The defaults are the brief's worked example (₹1,000 → ₹700 for one AC service); the commission is an illustration, not a term.
The society saves, per year₹36,000that is ₹180 per flat averaged over every flat, across 120 pooled jobs

Where it goes from here
Shipped, next, and later. The pilot proves fill rates and ratings in one city; the platform is already built to multiply.
