The estate operating system

The details of a great house, quietly handled.

Everything a house runs on, in one place, on everyone's phone. The routines, the procedures, the spend, the cellar, the record of who did what. Nothing left to memory or a group chat.

Built by an estate manager, for the people who run the house.

The operating system for the private estate.

Estate operations, quietly handled.

How it works

A house runs on rhythm. So does Tero.

Every morning, Tero generates the day's routines from your templates and assigns them by residence, by role, by shift. Staff see exactly what's theirs. You see everything.

7:30 AM

The morning sets up

The day's tasks appear automatically. Opened curtains, fresh flowers, the principal's breakfast, each one tagged to the right person before they arrive.

3:00 PM

The afternoon turns over

Shift changes without a handover meeting. The evening's setup, the table, the wine, the turndown are already waiting, already assigned.

After service

You see what was done

Every completed task, by whom and when. Every change to it, kept permanently. Oversight without standing over anyone's shoulder.

One search box

Ask the house a question.

One box that reaches every record the estate keeps. The cellar, the wardrobe, the vendors, the vehicles, the procedures. Ask in the words you'd use out loud, and Tero gives you the answer, not a folder to go looking through. It only answers with what that person is allowed to see, and when the records don't hold the answer, it says so.

What it does

One house, fully documented.

The things a great estate manager keeps in their head, now kept somewhere they can't be lost when you take a day off.

Daily routines

Build a checklist once; Tero generates it every day, by residence, by role, by shift. Morning and afternoon, butler and housekeeper.

Procedures

How the house is run, written down and translated into the languages the household speaks. A new hire learns the standard in the right order, in their own language, and no one has to be told twice.

Staff & roles

Every person signs in with their own login, and sees only what their position needs. A head housekeeper sees more. When someone leaves, a manager closes their access and it ends immediately.

Spend & budgets

Staff photograph a receipt and Tero fills in the form for them to check. Spend runs against budgets by residence and category, and the month-end report is ready to send from a phone.

Cellar & stock

The wine list with producer, region, and what each bottle pairs with, plus the cupboards behind it, counted and kept current.

Reminders & the log

Renewals, expiries, and unfinished work reach people by email, text, and phone notification. Every task change is kept permanently, so you can see who did what and when.

The kitchen

Menus by residence and day, built from the household's own dishes and ingredients. Tero flags any dish that clashes with what someone at the table cannot eat, and a person still confirms with the guest. Confirmed menus become a shopping list, netted against what is already in stock.

Medications & vitamins

What each resident and pet takes, how much and when, with a photograph of the bottle so whoever is covering gives the right thing. Private to managers and the principal until shared with staff, one row at a time. Refill reminders name the person, never the medicine.

The wardrobe

Every piece photographed and placed, by residence and closet. Trips to the cleaner or tailor tracked until they come back, a wear log, and packing lists checked going out and again coming home.

The whole morning, before you've had coffee

Every residence, how far along it is, which shift is behind, who is on today, who is arriving, and what the house has spent this month, all on one screen.

Every task, with the detail that matters

Each card carries the full instruction and the role responsible, so a new hire knows exactly how the house likes it done, first time.

One menu, and the house is in it

A short, plain list of the things a house actually has, grouped the way you'd think of them. Never more than two taps from wherever you are.

Who it's for

Tero was built behind the green baize door, by someone who has run the house, not just sold software to it.

Discretion by design

Built for houses that guard their privacy.

One household, sealed off from every otherSeparation is enforced inside the database itself, and an automated test proves it on every release.
The most sensitive data takes a private roadGate and alarm codes, allergies, medications and account passwords travel straight from the phone to the database, never through the web server.
Every change is kept, permanentlyWho changed what, and when. Nobody using Tero, managers and principals included, can edit or delete an entry once it is written.
In their words
Tero replaced three different systems we'd been patching together. The morning routines alone save us an hour a day.

The wine room looks amazing. It's so easy to keep stock and know what we have, wherever I go.

The Gen X in me was a little skeptical at first, but Tero quickly won me over. Having all of the house information in one organized place has made a real difference. It keeps everyone informed, improves communication, and adds a level of accountability that helps ensure things get done consistently and correctly.

Getting started

You start with a working system, not an empty screen.

The worry is always the rollout: the records to move, the staff to train, the weeks of half-use before it sticks. Here is what actually happens.

i.

Bring what you already have

Spreadsheets, staff lists, inventories, even photographs of documents get read in and turned into draft records. Nothing goes live until you have reviewed and approved it. Allergies are the deliberate exception: those are typed by hand, word for word, never imported.

ii.

Set up with you, not handed over

Your estate configured, your records loaded and reviewed together, staff accounts created, and two training sessions to walk the household through its first days. Everything on this page works today. None of it is a roadmap promise.

iii.

Nothing for staff to install

Tero saves to the home screen and opens like any other app. No app store, no IT department, nothing for a housekeeper or a groundskeeper to configure. They sign in, in their own language, and the day is there.

Founding client pricing

Simple, per estate.

One subscription covers the entire estate: every property, every member of staff, every feature. No per-seat charges, no feature tiers, and new features are included as they arrive.

These are founding rates, offered to Tero's first households.

1–2 properties
$399
per month
3–4 properties
$599
per month
5–6 properties

Custom
let's talk

Implementation, $999 one time. Your estate configured, your existing records loaded and reviewed together, staff accounts created, and two training sessions. You start with a working system, not an empty screen.

What counts as a property: a separate residence the household runs, such as a main house, a second home, or a guest house kept as its own operation. Rooms within one residence are not separate properties.
