“Honeymoon in March, overwater villa? Quote please!”
Desk drafts the reply overnight with live availability, your rate card and your own policies. By morning it is waiting for one click.
DeskThe operating layer for independent hotels
Guest email, front desk, kitchen and finance in one connected system, with an AI assistant that shows its work and asks before it acts.
HotelOS works above the PMS and accounting system you already have. It is business software for independent hotels from Island Inventions Inc., San Francisco.
Name and email to start · a founder replies within a day
11:47 pm, a Saturday
A honeymoon inquiry waits for a quote, the kitchen printer dies mid-service, and room 214 swears they never ordered that mojito. Five tools, five versions of the truth, and one very tired night auditor.
“Honeymoon in March, overwater villa? Quote please!”
Desk drafts the reply overnight with live availability, your rate card and your own policies. By morning it is waiting for one click.
Desk“Printer offline. 3 tickets waiting.”
Calm Kitchen queues the tickets, tells every till what is wrong, and prints them the moment the PC is back, stamped DELAYED so the pass knows.
Calm Kitchen“I never ordered that mojito.”
Every restaurant charge sits beside the room folio in Flow, and a charge already posted to the room is never counted twice. Nothing to argue about at checkout.
FlowSee it work
No stock footage and no pitch-deck mock-ups. The screens are faithful recreations of the product as it runs today, shown with fictional data.
The 11 pm quote, ready before the morning coffee.
Did the hotel make money last week? Know today, not after month-end.
The printer died on a Saturday night. Service didn’t.
Nexus, the AI in every app
Nexus is the assistant built into Desk, Flow, Clarity, Calm Kitchen, Command and HotelOS Go. It answers from your live data, shows how it got there, and turns a request into a proposal a person approves. Nothing changes until someone with the right role says yes.

Arrivals that need attention, where occupancy looks soft, what is running low for tonight, why expenses moved. In plain words, with tables and charts.
In Desk, answers name the documents they came from and when those were last updated. In Clarity, figures are checked against your data before the answer appears, and Command shows how each metric was verified.
A rule for honeymoon inquiries, next year's budget, an 86 for tonight: Nexus prepares it as a card. Approve it, or dismiss it. Guest emails are only ever drafts.
Each person's Nexus can see and do only what their role allows, and one conversation history follows them across the apps.
The six surfaces

Every guest email read and sorted as it lands, and every reply drafted with live availability, your rate card and your own policies.
Your team reviews and sends. The noise (OTA notices, payout statements, supplier pitches) stays out of the queue, and every arrival shows exactly what is still missing.
Explore Desk
Arrivals grouped by boat and car time, rooms moving from dirty to ready, and a folio that already includes dinner.
The front desk, housekeeping and operations board for the whole house, reading the same stays, the same notes and the same kitchen charges as everyone else.
Explore Flow
A morning briefing, a P&L you can click through, and profit by outlet while the month is still happening.
Clarity reads your accounting system, PMS and point of sale without ever writing to your books. Every figure Nexus shows is checked against your data first, and provisional numbers say so.
Explore Clarity
Decisions from every app in one place, owner-level approvals, and owner updates that draft themselves.
Command is where the GM and the owner see what needs them today, approve what the apps and Nexus propose, and manage people, access and connections for the whole group.
Explore Command
Point of sale, kitchen display and back office for hotel restaurants and bars, with room charges and meal plans handled the way hotels actually work.
Tickets that survive a dead printer, allergies the line cannot skip, half-board covered in the guest's favour, and a night that closes in one screen. Sales reach finance without an export.
Explore Calm Kitchen
The native staff app for iPhone and Android: today at a glance for your role, every product one tap away, and Nexus by voice.
Ask Nexus out loud, check what it heard, then send. Anything it proposes still waits for the right person's approval. Guests get a web app of their own for the concierge, requests and the bill, with nothing to install.
Explore HotelOS GoHow we build it
Replies are drafts until your team sends them. Changes Nexus prepares wait for approval. The big calls go to one queue for the owner.
The transfer time a reservations agent saves in Desk is on the front desk board in Flow. The dinner rung in Calm Kitchen is on the folio. The sale is in Clarity. Nobody re-types anything.
Numbers are marked provisional until your books close. Sync is described as “within minutes”, never “real-time”. If something is not live yet, we say so.
One guest, every department
Follow one honeymoon booking from the first email to the final bill. Every department reads the same stay, and nobody re-types what someone else already knows.
Before arrival
Desk drafts a priced reply to the inquiry, and the seaplane time the agent saves travels with the booking.
Arrival
Flow's front desk groups arrivals by boat and car time and shows exactly what is ready and what is missing.
The stay
Dinner is rung once in Calm Kitchen: live on the kitchen screen, on the room account, covered by the meal plan where it applies.
Checkout and after
Room and dining sit on one folio in Flow, and the revenue lands in Clarity by outlet, without an export.
While it is fresh
Your PMS, your shift pattern, your questions first, not a generic deck.
What changes
HotelOS does not replace your PMS or your accountant. It removes the re-typing, the chasing and the guessing between them, so the team spends its attention on guests.
Priced from your own rate card against live availability, with its sources on show, waiting for one click.
Kitchen and front desk share one folio at checkout: restaurant charges beside the room, nothing counted twice.
Profit by outlet, pace to target and variance to budget every morning, not a month after the fact.
Tickets survive a dead printer, allergies cannot be skipped, and every comp above your limit carries a manager's name.
Scope agreed in writing
HotelOS is business software from Island Inventions Inc., San Francisco. It brings hotel operations together above your existing PMS and finance systems. Each property starts with a scope agreed in writing.
01 / Scope
We agree the property, modules, users and workflows before onboarding. Product pages describe the intended capabilities; availability and limitations are confirmed for your deployment. Calm Kitchen is a separate engagement.
02 / Connections
Integration categories are areas to assess, not a list of certified connectors. We confirm supported data, read/write permissions, provider approvals and implementation requirements for your specific systems.
03 / Commercials
Review subscription fees, AI usage, onboarding costs, third-party charges, renewal, cancellation and support coverage in your proposal and order form. A demo request creates no account, subscription or payment obligation.
04 / Control
Your team remains responsible for access permissions, lawful data sharing and reviewing AI output and financial decisions. Review the privacy policy, DPA, data export and deletion terms before connecting operational data.
Try it on a property like yours
Tell us about your property and we set HotelOS up on your stack and your shift pattern: guest email, front desk, kitchen, finance and Nexus. Bring your GM, your controller, or both. Leave a name and an email; a founder takes it from there.
