How it works →
Automations & developersLive
The tersOS API
Developers can reach the same data through the tersOS API, documented with examples for every module.
CalendarsQ4 2026
Google Calendar
Bookings made in tersOS appear in your team's Google calendars, and a meeting booked straight in Google Calendar holds the room in tersOS.
CalendarsQ4 2026
Microsoft 365
The same for spaces on Outlook: room bookings land in Outlook calendars, and a room booked from Outlook is blocked in tersOS.
PaymentsQ4 2026
Stripe
Members pay invoices, day passes and event tickets by card in the app, and each payment is matched to its invoice without anyone at the desk touching it.
Door access & Wi-FiQ4 2026
Kisi
A member's door access follows their plan: active members get in during their hours, and a cancelled membership stops working at the door the same day.
Door access & Wi-FiQ4 2026
Salto KS
Keys issued and revoked from the member profile, with the same rule as Kisi: access follows the plan, and a day pass opens the door only on its day.
Door access & Wi-FiQ4 2026
UniFi
For spaces on Ubiquiti: members on the Wi-Fi are checked in automatically, and UniFi Access doors follow membership status like Kisi and Salto.
MessagingQ4 2026
Slack
A new booking, a parcel at reception, an overdue invoice or a new lead posts to the channel your team already watches.
Automations & developersQ4 2026
Zapier
Send new members, bookings and invoices to the thousands of apps Zapier connects, and start tersOS actions from any of them.
Accounting & e-invoicingQ4 2026
SEF & e-Račun
Invoices from tersOS are filed with Serbia's SEF and Croatia's e-Račun systems as they are issued, so spaces there stay compliant without re-typing anything.
MessagingQ4 2026
WhatsApp & Viber
Booking confirmations, parcel notices and event reminders reach members on WhatsApp or Viber, delivered through Infobip, the apps people in the region actually answer.
PaymentsPlanned
Monri
Card payments for spaces in Bosnia and Herzegovina and Croatia, where Stripe is not available, with the same invoice matching.
Door access & Wi-FiPlanned
Nuki
For smaller spaces on Nuki smart locks: members unlock the door from the app, and access follows their plan.
Accounting & e-invoicingPlanned
Xero
Invoices and payments from tersOS land in Xero as they happen, so the books close without re-typing.
Accounting & e-invoicingPlanned
QuickBooks
The same for QuickBooks: invoices and payments carried over as they happen.
MessagingPlanned
Microsoft Teams
The Slack alerts, posted to a Teams channel instead.
Marketing & CRMPlanned
HubSpot
Leads captured on your public page and by tersAI appear as HubSpot contacts, with their stage kept in step.
Marketing & CRMPlanned
Mailchimp
Members and newsletter subscribers kept in step with your Mailchimp audience, for spaces that keep sending from there.
PrintingPlanned
PaperCut
Printing charged to the member's tab through PaperCut, so print credits stop being a spreadsheet.
Sign-inPlanned
Sign in with Google & Microsoft
Staff and members sign in with the Google or Microsoft account they already use, with no separate password to remember.
None of the Q4 2026 and planned ones is live yet. If one of them is the reason you cannot switch, say so below and it moves up the list.
Tell us what you need first
Need one of these first?
Tell us which one and what it should do for your space. The ones with a date are planned for the fourth quarter of 2026; the rest move up when spaces ask.
After you ask
01 · We reply
A person reads it.
You get a reply within two working days, with an honest date for the one you asked for.
02 · You go first
Early access.
When the connection is ready, the spaces that asked try it before it is marked live on this page.
03 · The list moves
Asks set the order.
What spaces ask for most gets built first. This page is updated as dates firm up.
