Onboarding and migration

Send us whatever you have.

A spreadsheet, an export from Nexudus, a register with pencil in it. One person at Sehsaa takes it, builds your workspace, and hands it back working — branches, floors, desks on a map, members, agreements and what they owe you. Five working days. No migration fee.

Up to 250 desks and 100 member companies · Larger spaces get a date in writing on the first call

How it goes

Five days, five steps, one person who owns it.

You get their name, their number and their WhatsApp on the first call. Not a ticket queue, not a shared inbox.

Day 0

A 30-minute call

We go through your branches, floors, desk and cabin count, how many member companies you have, and what you are running on today. You leave the call knowing exactly which files to send.

Day 0–1

You send your data

Exports, spreadsheets, a PDF floor plan, photos of the register. Any format. If your old system will not give you a clean export, say so on the call — we work with what you can get.

Day 1–4

We build it in your workspace

Branches, floors, every desk and room on the floor map, member companies, agreements with their real dates and fees, each member on the desks they occupy, and your outstanding invoices.

Day 5

You review it, we fix it

We walk the floor map with you, screen by screen. Anything wrong is corrected the same day. Contradictions we found in your data get listed and asked about — we never guess a contract date.

Go-live

You pick the day

You name the date you stop using the old system. We are on WhatsApp that day and the two after it. Keep the old system read-only for 90 days; nobody sensible switches without a way back.

The deal, plainly

What you provide. What you get back.

Nothing on the left needs to be tidy. Cleaning up a member list is our job, not a condition for starting.

What you send us

  • Your branches and floors, with the names you actually call them
  • Your desk, cabin and meeting-room list — a spreadsheet, an export, or a photo of the board
  • Your member companies: name, GSTIN if they have one, state, and who to contact
  • Current agreements: start, end, notice period, monthly fee, deposit
  • Who sits on which desk today
  • Invoices still unpaid as at your go-live date
  • Your GSTIN and the state each branch is registered in
  • Your logo, your invoice prefix and the next number in your series
  • Your staff, with phone numbers and what each is allowed to do
  • Floor plan images or PDFs, if you have them

Missing half of this? Send the half you have. We will tell you what is still needed rather than sit on it.

What we hand back

  • Every branch and floor set up, with your floor plan behind the desks
  • Every desk, cabin and meeting room placed on a live map you can drag
  • Member companies with their contacts, GSTIN and state on file
  • Agreements with real dates, so renewals warn you before they land
  • Each member sitting on the desks they occupy, so occupancy is real on day one
  • Your unpaid invoices, so the outstanding list is right from the first login
  • Invoice numbering that continues your existing series, not a new one
  • Staff logins with roles and branch access, signing in by WhatsApp OTP
  • Your logo and details on the invoice PDF
  • A desks-and-rooms spreadsheet you can download, edit and re-upload yourself, forever

You review all of it before you use it. Nothing goes live because we said it was ready.

Where you are coming from

Four ways in. All of them end the same.

What to get out of your old system, what we do with it, and what is on your screen at the end.

From

A spreadsheet, or Google Sheets

The most common one, and the easiest. Most spaces run on a desk tab, a rent-roll tab and a renewal tracker that somebody keeps forgetting to update.

You send
  • The whole workbook, every tab, as .xlsx or .csv
  • Or just share the Google Sheet with view access
  • Your invoice book or accounting export, if invoices live elsewhere
We do
  • Map your columns onto Atrium's, and tell you what has no home
  • Create branches and floors, then load desks and rooms in bulk
  • Enter members, agreements, seat allocations and open invoices
  • Flag every row that contradicts another and ask you about it
You end up with

The same rows, on a floor map, that now bill themselves. And you keep the spreadsheet habit where it helps: desks and rooms download to Excel, edit in Excel and upload back — Atrium shows you the diff and waits for you to press Apply.

From

Nexudus, OfficeRnD, Cobot, Spacebring or Archie

All five hold your data in lists you can export from their admin. Pull each list you can see on screen, and ask their support in writing for a full account export at the same time — it is your data, and asking early saves a week at the end.

You export
  • Resources: desks, hot desks, cabins, meeting rooms
  • Members and teams or companies, with contacts
  • Contracts, plans or memberships, with start and end dates and prices
  • Invoices — at minimum every one still unpaid
  • Your floor plan image, and any document you still need
We do
  • Turn the resource export into Atrium's desks-and-rooms sheet and load it
  • Rebuild your companies as members with GSTIN and state, so GST is right
  • Rebuild plans and contracts as agreements with notice periods
  • Put each company on the desks they hold, so your map matches theirs
  • Carry unpaid invoices across as opening balances
You end up with

The same desk names, the same members, the same money owed — priced in rupees, with GST split by place of supply, and no second bill for your second branch.

Read this before you cancel. Their booking history, community feed, integrations and any stored card or auto-charge mandate do not come with you. Cancel only after your go-live day, and keep read-only access for 90 days.
From

Digicuro or Brskly

Indian platforms, so your GST history matters more here than anywhere else. Your filed returns stay filed — nothing we do touches them — but your invoice numbering has to continue cleanly, and that is the part people get wrong.

You export
  • Members with GSTIN, PAN and state, and their contacts
  • Agreements with dates, fees, deposits and notice periods
  • Your desk and cabin inventory per branch and floor
  • Invoices raised in the current financial year, and every unpaid one
  • Your invoice prefix and the last number you issued
We do
  • Set Atrium's series to continue from your last number, so no number is ever issued twice
  • Rebuild members, agreements and inventory as above
  • Load unpaid invoices with their original issue dates
  • Check your branch state codes against your GSTIN before a single invoice is raised
You end up with

An unbroken invoice series, an outstanding list that reconciles with theirs on go-live day, and CGST/SGST or IGST decided by where the space is rather than by a dropdown someone forgot.

Ask for your export in writing, early. Quote-only vendors are quote-only about exports too. If you hit a wall, tell us on the call and we will work from what you can see on screen.

Paper, a whiteboard and WhatsApp

No export exists. That is fine — this is the case we built the service for, and typing it in is our job, not yours.

You send
  • Phone photos of the desk board or seating register
  • The agreement folder — scans or photos, one per member
  • The last three months of your invoice book
  • A voice note about anything the paper does not say
We do
  • Type all of it, and read it back to you before it counts
  • Draw your floors and place every desk where it sits in the room
  • Attach each signed agreement to the member it belongs to
  • List every contradiction we find and ask — we do not invent a date
You end up with

The first time your occupancy number and your invoices come from the same rows. Expect the two to disagree at first. That gap is the reason to do this.

The honest part

What comes across, and what does not.

Finding this out after you have switched is how a customer becomes an enemy. So here it is before you decide.

Comes across

Everything you need to run tomorrow morning.

  • Branches, floors, desks, cabins and meeting roomsPlaced on a live map, with your floor plan behind them.
  • Member companies and their contactsWith GSTIN, PAN, state and billing address.
  • Live agreementsStart, end, notice period, monthly fee, deposit, and which floors they cover.
  • Who sits where, todaySo occupancy is real from the first login rather than after a month of data entry.
  • Unpaid invoicesWith their original issue dates, so ageing and collections are right.
  • Your invoice numberingYour prefix and your next number, continuing your series.
  • Current signed agreements and member KYCAttached to the member or agreement they belong to.
  • Your staff, with roles and branch accessSigning in by WhatsApp OTP on day one.
  • Your brandingLogo and company details on the invoice PDF and the public pages.

Does not come across

Say now if any of these is a problem. Some have a workaround; some do not.

  • Historical bookings and meeting-room historyLast year's room bookings are not re-created. We archive your export as a file you keep — but they are not searchable inside Atrium.
  • Invoices already raised and settled elsewhereThey stay in your old system and in your accountant's books, which is where a filed return expects them. Only unpaid ones are carried, as opening balances.
  • Stored cards, mandates and auto-charge schedulesThese do not transfer between any two systems, by design. Members re-authorise wherever you collect.
  • Your old visitor register historyThe register starts fresh on go-live day. Keep the old book.
  • Your members' old logins and passwordsNobody can move a password hash. Members sign in with a WhatsApp OTP instead, so there is nothing for them to remember.
  • Custom fields your old system let you inventAnything without a home in Atrium goes into the notes on the member or the desk. We show you the list before we do it.
  • Years of archived attachmentsWe carry current agreements and KYC. A ten-year document archive is a separate conversation, not a five-day one.
  • Door access, cards and turnstilesAtrium does not do access control at all. If your old platform opened your doors, keep that platform for that job.

Migration checklist

Walk your floor with it. Tick as you go. Nothing on it needs Atrium open.

Before the call

15 minutes
  • Count your branches, and the floors in each
  • Count desks, cabins and meeting rooms per floor
  • Count your member companies, and how many are on notice
  • Note what you run on today, and who administers it
  • Decide who at your end signs off the migration

Get out of your old system

Day 0 to 1
  • Export resources: desks, cabins, meeting rooms
  • Export members and companies, with contacts
  • Export contracts or plans, with dates and prices
  • Export invoices — at minimum every unpaid one
  • Download your floor plan images or PDFs
  • Ask their support in writing for a full account export
  • Note your invoice prefix and the last number issued

Gather from your own records

Day 0 to 1
  • Your GSTIN, and the state each branch is registered in
  • Each member's GSTIN, PAN and state
  • Deposits held, per member
  • Notice periods, per agreement
  • Who sits on which desk, today
  • Signed agreements as PDFs or photos
  • Staff names, phone numbers and what each may do
  • Your logo, as a PNG or SVG

Decide

Before day 5
  • Your go-live date, and which branch goes first
  • Whether to carry unpaid invoices or start clean
  • Who tells your members, and when
  • How long the old system stays read-only — 90 days is sensible

On review day

Day 5
  • Walk each floor map against the real floor
  • Check every agreement end date and notice period
  • Check the outstanding total against your old system
  • Raise one test invoice and read the GST split
  • Check the invoice number continues your series
  • Open the invoice PDF and check your logo and address
  • Log in as each staff role and confirm what they can see

Go-live week

Day 6 onward
  • Stop entering new data in the old system
  • Set the old system to read-only, do not cancel it
  • Tell members where day passes and bookings now come from
  • Raise the first real invoice run and check it end to end
  • Reconcile the first week's payments against the bank
  • Book the 30-day review with us

Questions

Before you ask.

What does the migration cost?

Nothing. It is not an add-on, a professional-services line or a launch promotion we withdraw later. If your move is genuinely larger than five days of work — thousands of members, or a decade of documents — we say so on the first call and agree the scope in writing before anyone starts.

Five working days from when, exactly?

From the day your files land with us, not from the day you first email. The clock stops if we are waiting on an answer from you, and we tell you when it does. Up to 250 desks and 100 member companies, five working days. Above that, you get a date on the first call and we hold it.

My free month is 50 desks. My space is bigger than that.

Tell us on the call. We set your workspace up at your real size for the trial so your whole inventory goes in — there is no point evaluating Atrium on a third of your floor.

Do you touch our old system?

No. We never ask for a login to it and we would decline one. You export; we import. That way there is nothing we could break, and your old contract stays entirely between you and them.

What if the data we send you is a mess?

It usually is, and that is the point of a person doing this rather than an upload button. What we will not do is guess. Every contradiction — a desk on the board that no agreement covers, an agreement with no end date, two members with the same name — comes back to you as a list of questions.

Can we do it ourselves instead?

Partly, and the part you can do is the big one. Desks and rooms are a spreadsheet round trip you own: download the template, fill it in Excel, upload it, read the diff of what will change, press Apply. Members, agreements and invoices are entered screen by screen today, which is exactly why we offer to do them for you.

What happens if we leave Atrium later?

You get a full export of everything — members, agreements, bookings, invoices and payments. Each customer's data sits in its own separate database, so what you get is a clean copy rather than a filtered extract. We would rather lose you cleanly than hold your data hostage.

Next step

Book the 30 minutes. Bring your worst spreadsheet.

You will leave the call knowing exactly what to send, what we will do with it, and the date your space goes live. If we are not the right fit for you, we will say so on that call rather than after your migration.
