Atrium runs your coworking space end to end — live floor maps, bookings, GST invoicing and WhatsApp notifications. Built for Indian operators, priced in rupees.
₹79 per occupied desk, down to ₹49 at scale · Unlimited branches and users · No setup fee
The problem
Every operator we've talked to runs on some mix of a spreadsheet, a WhatsApp group and someone's memory. It works until it doesn't.
The board says 80%. The invoices say something else. Nobody can tell you which desks are actually earning today.
Eleven agreements end next month and you find out when a client mentions it in passing.
Payment received, not recorded. Recorded, not reconciled. Chased twice, or never.
You learn about it when two members are standing in the same doorway at 3pm.
Every enquiry lives in your sales person's WhatsApp. When they leave, it leaves with them.
No record of who was in the building, which host they met, or when they left.
What Atrium does
Not a booking widget bolted onto a spreadsheet. The whole operation.
Every branch, floor, room and desk on a plan you can actually click. Occupancy at a glance, tenant and contract end date on hover.
Desks, cabins, meeting rooms on 30-minute slots, day passes and night passes. Overlaps are rejected by the database, not by someone remembering to check.
Companies, contacts, service agreements with notice periods and deposits, and rate cards per branch.
GST invoices with SAC codes and the place of supply set to the branch. Record payments by UTR, reconcile against invoices, chase what's overdue.
A proper visitor register that keeps the ID type and only the last four digits of the ID number. The host is told on WhatsApp. Day passes issued with a reference the front desk can check in seconds.
Leads with requirement, budget, follow-up date and owner. Tours booked, proposals tracked, nothing living in one person's phone.
GST and MCA registration addresses, a log of post received, and a generated document pack — NOC, licence agreement and address-proof cover — with an expiry warning on every address proof.
Visitors buy a day pass or book a tour from your own page and pay online through your own Razorpay account. We switch the page on for you on request.
Built for India
International coworking software is good. It also bills you in foreign currency and treats GST as an edge case.
SAC codes on every line and the place of supply set to the branch, so a member registered in another state is still charged CGST + SGST correctly — not a tax field you fill in by hand.
B2B and B2C invoices grouped the way the return wants them, with anything that needs review flagged before your accountant files — not after.
Booking confirmations, day passes, renewal reminders and payment chases where your members actually read them.
Record UPI, NEFT and cheque payments by their UTR or reference, and take UPI online through your own Razorpay account.
Not a premium add-on. Indian buildings need it, so it ships with every plan.
No forex, no card in dollars, no per-location or per-user fees.
Onboarding and migration
The reason operators stay on software they have outgrown is the week of typing it would take to leave. So we do that week. Send us whatever you have — an export from your current platform, a spreadsheet, or photos of the desk register — and one person at Sehsaa builds your workspace and hands it back working.
You get a named person — their number and their WhatsApp, not a ticket queue. You leave the call knowing exactly which files to send.
Branches, floors, every desk and room on the floor map, your members, their agreements with real dates, who sits where, and what they still owe you.
We walk the floor map with you. Anything wrong is fixed the same day. Where your data contradicts itself we ask you — we never invent a contract date.
You name the date you stop using the old system. Keep it read-only for 90 days afterwards; nobody sensible switches without a way back.
Historical bookings, invoices already raised and settled elsewhere, your old visitor register, and any stored card or auto-charge mandate. None of those move between any two systems, and we would rather you knew that now than after you cancelled.
Pricing
Desks are counted at the end of the month, so an empty desk costs you nothing. A private cabin is billed as the seats inside it that are let — the two spare seats in a four-seater cost nothing until you sell them. Every branch, every staff login and every member account is included, however many you have. What else is charged for is listed below.
500 occupied desks across 5 branches, 12 meeting rooms, 40 staff logins:
Atrium — ₹31,900/month (500 × ₹59 + 12 × ₹200).
A platform charging per location starts at five location fees before a single desk is counted.
Already running on something else? Moving is free for spaces up to 250 desks and 100 member companies, and takes five working days — you send your export or your spreadsheet, we build the whole workspace and you review it before it goes live. See what moves and what does not →
Comparing Atrium with other coworking software? Atrium charges per occupied desk, in rupees. Most of the eleven other products we compared charge by plan or member band, in US$, euros or pounds, and several offer member phone apps that Atrium lacks. Every figure comes from the vendor's own pricing page, and the comparison says where Atrium is behind. See the comparison →
See it on your own floor
Send your desk list — a spreadsheet, an export, even a photo of the floor plan — and we will have your branches, floors and desks in Atrium before we speak. You see your own space on the call, not a sample one. Moving from your current system is free for spaces up to 250 desks and 100 member companies.
Tell us about your space and we'll come back within one working day.
Questions
₹79 per occupied desk a month for up to 150 occupied desks, ₹69 for 151–400, ₹59 for 401–750 and ₹49 above 750 — every desk at the rate of the band your total falls into. Bookable meeting rooms are ₹200 each a month, paid day and night passes ₹20 each after the first 20 free every month, and virtual-office clients ₹50 each a month. The minimum is ₹2,499 a month, and passes and virtual office count inside it. Branches, staff logins and members are unlimited, and there is no setup fee. All prices exclude 18% GST.
Yes. A new workspace is free for 30 days, with no card and no commitment, for up to 50 desks and 10 bookable meeting rooms across unlimited branches, floors, staff and members. When the 30 days end the workspace becomes read-only until you choose a plan — everything stays visible and nothing is deleted.
Five working days from the day your files reach us, for a space up to 250 desks and 100 member companies. Send us your current desk list and member spreadsheet — or an export from whatever you run today — and we do the migration: branches, floors, desks, members, agreements, who sits where, and your outstanding invoices. You review all of it before anything goes live. Larger than that and you get a date on the first call, in writing. Here is the whole process, and what does not come across.
No. Confirmations and reminders arrive on WhatsApp, on the number you already have for them. Members can also sign in to a browser portal to see their bookings and invoices. Nothing about Atrium requires anyone to download or sign up for an app.
Yes. The place of supply on a member invoice is your branch, so a member registered in another state is still charged CGST + SGST correctly. SAC codes are set per invoice line — 997212 for coworking rental — and invoices continue your existing number series with your logo. The GSTR-1 report gives your accountant CSV files in the GST offline-tool format for B2B, B2CS, the HSN summary, documents issued and credit notes; anything that contradicts itself is held back for review. It does not produce B2CL, exports, advances or amendments.
Yes. Booking confirmations, day passes, renewal reminders and payment reminders are sent from Atrium and we do not charge you for them. We pay the messaging provider ourselves; if that ever has to change, clause 5.7 of the Terms binds us to sixty days' written notice first. If you want messages to come from your own WhatsApp Business number, we set that up for you on request, through your own Fast2SMS account.
In India. Atrium runs on a server in DigitalOcean's Bangalore region, and each operator's data sits in its own separate database — not a shared table filtered by a column. Backups run every day and are kept for 90 days.
Ask us in writing and we send you a full export of your workspace within five working days, at no charge (clause 10 of the Terms). Each customer's data sits in its own separate database, so an export is a clean copy rather than a filtered extract.
Not as a packaged product. Atrium is a hosted service, and each operator's data sits in its own database in India. If a policy requires your own infrastructure, a self-hosted arrangement can be quoted case by case under its own agreement (clause 5.10 of the Terms) — write to contact@sehsaa.com.
Sehsaa Solutions Private Limited. Before Atrium was a product, we built a coworking management system end to end, which is why the awkward parts — notice periods, seat-versus-cabin, GST place of supply — are handled properly rather than approximated.
