Built for Indian housing societies · Made in Nashik
Society management, finally made simple. Bini replaces the register at the gate, the WhatsApp group nobody can search and the month-end chase for dues, all with one calm app your committee can actually run.
Live in one dayNo ads, ever₹15 per flat, per month
No ads. No data selling. Ever. Not a slogan. A clause in the contract your society signs.
In one sentence
Built for Indian housing societies and nothing else. Not a visitor app with a few extra tabs, and not an accounting package somebody has to be trained on. One system where the resident, the guard at the gate, the committee and the society’s own records all work from the same information, so nothing has to be re-typed, forwarded, or held in one exhausted person’s head.
Eight things your society already does every week. Today they live in a register at the gate, a spreadsheet on somebody’s laptop, a cupboard in somebody’s flat and four WhatsApp groups. In Bini they live in one place, and they agree with each other.
Watch it first, no form to fill
Not a product tour. Four ordinary moments in a society, someone at the gate, a complaint, the dues and the AGM, and what each one looks like once Bini is running.
Have us walk your committee through the same thing, live on a call.
Book a 20-minute walkthroughThe way most societies run today
None of it is anyone’s fault. It is simply what happens when a housing society is run by people with day jobs, in the two hours they have left in the evening.
A paper register nobody reads, half-legible names, and no way to check a delivery from three Tuesdays ago. When something goes missing, the society has nothing to look at.
“Who let them in? Check the register.” And nobody can read it.
Payment screenshots in three different chats, a ledger living in one person's Excel, and the same eleven flats reminded politely, every single month.
“I have paid, sir. I will send the screenshot.” Every month.
Numbers assembled the night before, a question from the floor nobody can answer on the spot, and the same quiet trust gap that comes back every single year.
“And where exactly did the repair fund go?” Then silence.
Bini does not ask your committee to become software people.
It just quietly does the paperwork.
What actually changes
Not fifty half-finished features. Five, and there is a real screen behind each one. Every image here is an actual screenshot, not a mock-up. Money has a section of its own, further down.
How the pieces fit together
The resident, the guard and the committee each get only the screen their job needs, three ways into one app, and all three write to the same record underneath. It is one Bini and one rate for your whole society, not three products to buy.
For every flat · Android & iOS
What changes: nobody phones the flat, and nobody argues about what was announced.
For the gate · any Android tablet
What changes: the register book stops being the only record of who came in.
For the office-bearers only
What changes: the treasurer stops rebuilding the month from screenshots.
One record underneath all three.The guard’s entry, the resident’s payment and the committee’s report are the same data seen from three sides, which is why the month-end reconciliation your treasurer dreads simply stops existing.
There is an administrator’s console in Bini, and your committee will never have to open it. Setting your society up, importing the flat list, the owners and the opening balances, and correcting anything that looks wrong afterwards, all of that happens on our side of the glass. That is the whole reason a society goes live in one working day instead of a fortnight of configuration, and the reason nobody on your committee has to become the person who understands the software.
Announcements, and the emergency button
A notice in a WhatsApp group is read by whoever happens to be scrolling at the time. In Bini it sits at the top of every resident’s home screen, with the poster exactly as your committee made it, and you can see which flats have opened it.
One tap on the SOS screen reaches the guard at the gate and your committee. It does not broadcast to the neighbours, because an emergency is not a group message and nobody should have to explain theirs to ninety flats. The same screen carries police, ambulance and fire, so nobody is hunting for a number that was pasted inside a lift two years ago.
The notice, the SOS screen, the gate and the ledger are one app with three roles inside it: the resident, the guard and the committee. There is no separate emergency app to install in January and forget by March, and no second thing to teach a watchman.
The money: where it goes, and where it doesn’t
Bini is software, not a bank. We are not a wallet, not a gateway and not an aggregator. A resident pays by UPI and the money moves from their bank into your society’s bank, through an RBI-licensed partner. Bini never holds a single rupee of society money.
Bills raised automatically on your schedule. Reminders that go out without anyone having to be the bad guy. Receipts issued the second a payment lands, and a ledger that keeps itself. Interest on arrears is applied automatically, on whatever rule your society has already agreed, so nobody has to work it out by hand or be the one who raises it.
Penalties, festival funds, a one-off lift repair: each raised with a written reason and a full audit trail, so nobody has to ask six months later what the money was for.
Said plainly:the standard charges of UPI and the payment partner apply as they do anywhere else, and we do not pretend otherwise. What we promise is that your society’s money always moves straight from bank to bank, and Bini never holds it or becomes a middleman for it.
Maintenance, collections and what went out
Most society apps will show a committee what came in. The harder question at every general body meeting is what went out, and on whose say-so. In Bini both live under Payments as two tabs, Collection and Spent, and neither of them needs a spreadsheet to answer.
Worth saying:showing you the money is not the same as touching it. Every rupee still moves bank to bank into your society’s own account, exactly as the section above describes. Bini keeps the record, not the money.
The report that ends the argument
In Maharashtra the AGM is due by 30 September, and every year the same evening disappears into assembling figures. Bini keeps that report current all year. On the day, you print it.
Traditional society management vs Bini
Nothing exotic here. This is the ordinary week of a managing committee, before and after. Read the ‘today’ half and see how much of it you recognise.
If you read the ‘today’ half and thought “that is exactly our society”, that is the whole reason Bini exists.
Data security & privacy
A society app holds the names, flats and phone numbers of every family in your building. That is not a small responsibility, so here is exactly how it is handled, in plain words, with no jargon to hide behind.
Your society's records sit on managed cloud servers in India, monitored and kept up to date. Not on a laptop in somebody's flat, and not on a hard disk that changes hands with the committee.
Everything travelling between the app and our servers goes over an encrypted connection, the same kind of protection your bank's app uses. Nobody on the society Wi-Fi can read it in passing.
Backups are taken automatically, without anyone having to remember. A lost phone, a broken gate tablet or a committee handover does not cost your society its records.
The guard sees the gate. A resident sees their own flat. Only the office-bearers see the money. Nobody sees more than their role needs, including a resident who is curious about a neighbour.
It is the society's record, not our asset. Ask for a full export in a readable format and you get it. Ask us to delete everything and we do, on the timeline written into your agreement, with two reminders before anything goes.
Resident details are never sold, rented or handed to an advertiser, and no third party pays us for a look at them. This one is not a policy we could quietly revise. It is a clause in the agreement your society signs.
We ask for what running a society actually needs and nothing more. No tracking of where residents go once they leave the gate, no reading of their messages, no quiet building of a profile behind them.
Everything on this page goes into the one-page summary we hand you before the meeting, so your secretary is not repeating a website from memory to a room full of members.
And the honest part.We do not hold enterprise security certifications yet, and we are not going to imply that we do. What we can tell you, on the call and in writing, today, is exactly where your society’s data lives, who can see it, how to get all of it back and how to have it erased.
Why committees choose Bini
Most society apps are free because your residents are the product: their addresses, their movements, their spending. We would rather charge fifteen rupees and be able to look your committee in the eye. That is the part we will not trade away, and these are the eight reasons committees give us for signing.
No banners, no sponsored offers, no “partner deals” pushed at your residents. The app stays a tool, not a shop window.
Stored on servers in India. The society owns its records, can ask for them at any time, and can have them deleted on the timeline written into the agreement.
The promise is not a line on a website we could quietly edit later. It is a clause in the agreement your society signs.
One rate per flat, everything included. No modules to unlock, no charge for another guard, another login or another notice board.
Send us the flat list and your society is live the next day. No consultants, no six-week implementation, no training manual to read.
Maintenance heads, arrears, daily help, the AGM report, guards who work in Marathi. Not a foreign product with rupees bolted on.
Call the number on this page and you reach someone who knows your society by name, not a ticket number and a queue.
Updates are included, always. What committees ask for on a Monday has a habit of appearing in the app a few weeks later.
Fifteen minutes is usually enough to tell whether this suits your society.

This is the plain arithmetic of an ordinary 250-flat society, worked through so you can see the shape of what Bini takes off the committee’s hands. The figures are illustrations rather than any one society’s results. Put your own flat count into the calculator in the next section and the money moves with it.
At about six visitors a flat a month, deliveries and cabs included, that is fifteen hundred arrivals a paper register can never be searched back through. In Bini each one carries a photo, a flat and a time.
Illustrative · 250 flatsOne reminder a flat, each cycle, going out on its own, instead of a committee member working down a list on WhatsApp on a Sunday evening and apologising for it.
Illustrative · 250 flatsEvery complaint gets a number, an owner and an age anyone on the committee can see. Nothing depends on somebody remembering to scroll back through a group.
How the product worksWe do the setting up: flats, wings, members, maintenance heads, and the guard trained at the gate. Your committee hands over a list and says go.
What we commit toA worked example
Take a 250-flat society billing ₹2,500 of maintenance a flat a month. Over a year that is seventy-five lakh rupees of society money raised, chased and reconciled through Bini, and settled straight into the society’s own bank account, never into ours. Bini’s share of it, at the standard rate, is about sixty paise in every hundred rupees.
Illustrative arithmetic, not a result from any society. It uses the standard ₹15 rate, excludes GST, and assumes every flat pays. Your own figures go into the calculator in the next section.
Pricing, the whole of it
Nothing to explain to the committee at renewal: no modules to unlock later, no per-feature upsell, and no charge for adding another guard, another notice or another committee member.
Billed annually. GST applicable. Everything below is included from day one. Nothing is an add-on.
That is about ₹0.49 per flat, per day, or ₹39 a day for the whole society.
Illustrative. Excludes GST. Gate devices, if you want them, are purchased separately: a tablet is about ₹15,000 or a phone about ₹12,500, one time, or we set up a device you already have for ₹1,500 to ₹2,500. The society owns the device either way.Open until 31 December 2026
Held for three years, plus the first two months free.
Why we are doing this
A new expense has to be carried through a general body meeting, and a smaller number makes that a much shorter conversation. We would rather a society start this year at ten rupees and stay for years than argue about fifteen and put the decision off another season. Nothing has been taken out of the product to get there.
All we ask in return: tell us honestly how it is going, and introduce us to a society or two you know. After the three years, the standard ₹15 applies. Societies that start after 31 December 2026 go on to the standard rate from day one.
Book a demo before the dateNot sure it fits? We will tell you honestly on the call, and there is no contract until you say yes.
Book a free demoGetting started in one working day
Not a six-week implementation. Give us your flat list in the morning and your guard is logging visitors the same evening, because we do the setting up, not your committee.
A live walk-through on your own screen: the guard app, the resident app and the reports. Ask anything. No slide deck, no pressure, and no obligation at the end of it.
We hand you everything the committee needs to decide: a one-page summary, the pricing in writing and the privacy clause. Take it to your meeting; we will join on a call if that helps.
Your flats, wings, members and maintenance heads entered by us from your existing list. The gate runs on any Android tablet, either yours or one purchased separately if you would rather we supply it.
We sit with your guards where they actually work, in Marathi or Hindi. There are four buttons on their screen. By the end of the shift it is muscle memory.
A ready-made WhatsApp message and a printable notice for the lobby. Residents download, enter their flat number and they are in. No forms, no training session to organise.
The first week is where the small questions come up, so that is the week we watch most closely. Founder-led support after that, for as long as your society uses Bini.
Everything above is done for you. Your committee’s only job is to say yes and hand over the flat list.
Start with a free demoWhy Bini exists
Nobody joins a managing committee hoping to spend their evenings reconciling payment screenshots.
Bini did not begin with a market study. It began with the ordinary, repeating friction of running a housing society: a register at the gate that nobody could read back, a treasurer holding the ledger together in one spreadsheet, and a WhatsApp group where every decision eventually got buried.
The software that already existed was built for large developers and property firms: heavy, expensive, and assuming a full-time office to operate it. An ordinary housing society does not have that. It has four or five people with day jobs, doing this after hours because somebody has to.
So Bini was built the other way around, for the volunteer rather than the administrator. Anything that needed explaining twice was removed. Anything a committee member could not do on a phone, standing in a corridor, was redesigned. And the two things that quietly cost societies the most, advertisements sold against their residents and data sold behind their backs, were ruled out in the contract rather than in the marketing.
It is a smaller product than an ERP on purpose. It does the paperwork of a society properly, and it stops there.
Damselfly Technologies was established in 2021. Bini took until 2024 to be worth putting in front of a committee, and it has been running in societies since. Three years is a long time to spend on something this ordinary. It is also why a guard can be taught the gate screen in forty-five minutes.
Jayesh RamsinghaniFounder, and the person who answers the phone
Straight answers
These are the ones that come up on almost every call, answered here exactly as we would answer them on the phone.
A day, in most societies. We enter your flats, wings, members and maintenance heads ourselves from whatever list you already have: an Excel file, a printed sheet, even a photograph of the register. Guard training takes about 45 minutes at the gate. Residents are usually on the app the same evening. Your committee's only job is to hand over the list and say go.
No. The guard app runs on any reasonable Android phone or tablet, so if your gate already has a device, use it. If you would rather have a dedicated one set up and handed over ready to work, a tablet is about ₹15,000 and a phone about ₹12,500, one time. Bring your own and we configure it for ₹1,500 to ₹2,500. It is purchased separately, it is not part of the per-flat price, and the society owns it. Nothing about the software depends on buying hardware from us.
The society does. It is stored on servers in India, it is never sold or shared with advertisers, and you can ask us for a full export at any time. Deletion follows the timeline in your agreement: thirty days to take your export, ninety days before we delete it, and a reminder from us before each of those. This is not only a promise on a website we could quietly edit later; it is a clause in the agreement your society signs.
Then you stop. There is no lock-in beyond the term you have paid for, no exit fee, and no holding your records hostage. We hand over your data in a readable format on the way out. We would obviously rather hear what went wrong and fix it, but a society that stays only because leaving is painful is not a customer we want.
This is the question we were designed around. A resident does three things: approve a visitor, pay maintenance, read a notice. Each is one screen and one tap, in the same shape as the apps they already use. In practice the residents who worry most about this are on it within a week, and for the few who are not, their family member or the committee can act on their behalf.
Included. Setup, guard training at the gate in Marathi or Hindi, the committee walk-through, the resident announcement material and every update afterwards. All of it sits inside the per-flat price. There is no implementation fee and no annual “support package” to renew.
You get a person. Call or message the number on this page during working hours, Monday to Saturday, and you reach the founder or someone who knows your society by name, not a ticket number in a queue. The first week after go-live is watched most closely, because that is when the small questions appear.
Never. Bini is software, not a bank, wallet or aggregator. A resident pays by UPI and the money moves from their bank to your society's bank through an RBI-licensed partner. The standard UPI and payment-partner charges apply as they do anywhere else. Your bank statement remains the record of truth.
Take the demo first, then take our one-page summary to your meeting. It has the pricing in writing, what is included and the privacy clause, so nobody has to take your word for it. If the committee wants to see it live, we will join your meeting on a call or come in person if you are in or around Nashik. There is no contract until the society formally says yes.
Something we have not answered? Ask it on the call, or just message us and we will reply honestly, even if the answer is “Bini does not do that.”
