An honest guide
Do you actually need a PMS for one or two properties?
Short answer: usually not. A property management system is a real tool for a real job — but for most hosts with one villa, two flats or a handful of rooms, the job it solves is not the job you have. Here is how to tell which side of that line you are on, before you burn another free trial finding out.
What a PMS is actually for
Strip the marketing and a PMS subscription buys four things: a two-way channel manager (your availability is pushed back to Booking.com, Airbnb and the rest, so a booking on one portal closes the dates everywhere), a unified guest inbox across portals, a direct booking website with payments, and dynamic pricing. Each of those replaces genuine weekly hours — if your operation generates that work in the first place.
One villa listed on one portal, with a few regulars booking by phone, generates almost none of it. That is why so many small hosts finish a two-week trial of a big suite having used exactly one screen: the calendar. The suite was not bad. It was answering questions they never asked.
You probably don’t need a PMS if…
- you list on one portal (or none) and take the rest by phone or repeat guests;
- your real problem is seeing occupancy at a glance and not double-booking;
- you answer guest messages happily inside the Airbnb or Booking.com app;
- the monthly fee would exceed what an occasional lost booking costs you.
You genuinely do need one if…
- you sell the same units on three or more channels at once — two-way sync stops being a luxury and starts preventing double bookings you cannot prevent by hand;
- a direct booking website with payments is part of your strategy;
- you want dynamic pricing tuned to demand;
- a team works the same inbox and task list every day.
The three honest options at small scale
| Spreadsheet | Free calendar app | Full PMS | |
|---|---|---|---|
| Cost | Free | Free (the honest ones — see below) | Monthly subscription, often tiered by rooms |
| Double-booking protection | None — you are the protection | Yes — a proper one refuses the overlap outright | Yes, across portals too |
| Portal bookings visible | Typed in by hand | One-way iCal import — they appear in your calendar, but your availability is not pushed back | Two-way sync — dates close on the portals for you |
| Works in a doorway, offline, one-handed | Barely — spreadsheets fight phones | Yes — that is the whole point | Usually browser-first; varies |
| Time to useful | You build it yourself | Minutes | Days, plus onboarding |

The trial-fatigue trap
InnGrid exists because of a specific person: a host with one villa and ten rooms who tried the well-known apps and quit every trial. Not because they were bad — because each was a ~€20-a-month suite where he only ever opened the calendar, and paying a channel-manager price for a calendar felt wrong. He went back to his spreadsheet every time. If that loop sounds familiar, the fix is not a better suite. It is matching the size of the tool to the size of the operation.
When a calendar app — ours included — is the wrong answer
If you actively sell the same rooms on several portals, a one-way iCal import does not protect you: it shows you the bookings, but it will not close dates on the other portals, and the gap between those two is exactly where cross-channel double bookings live. That job needs a real channel manager. Likewise if you need Android, a web dashboard, guest messaging or invoicing — InnGrid runs on iPhone, iPad and Mac, and deliberately does none of those things. Read the comparison pages above; they name the products that do.
What the free layer can honestly include
A calendar can be genuinely free forever because it runs on your device, with no server behind it — there is nothing for the developer to keep paying for, so there is nothing to make you keep paying for. In InnGrid’s case the free part is the occupancy board (rooms × nights), unlimited rooms and bookings, double-booking protection, a guest directory, monthly and yearly stats, a daily housekeeping list you can text to your cleaner, arrival and payment reminders, backup and CSV export, and 11 languages. The paid part is optional and narrow: iCal import from portals, private iCloud sync, several buildings on one board, and sharing the calendar with a co-host or cleaner — the person you share with pays nothing.
Questions people actually ask
Is a spreadsheet really enough for a small rental?
Often, yes — until one of two things happens: you double-book a room because nothing warned you, or you find yourself running the operation from your phone in a doorway and the spreadsheet fights back. Those two moments, not room count, are the honest signal to move to a purpose-built calendar.
What is the difference between iCal import and a channel manager?
iCal import is one-way: bookings made on Booking.com or Airbnb appear in your own calendar, so you see everything in one place. A two-way channel manager also pushes your availability back and closes dates on the portals for you. If you actively sell the same rooms on several portals at once, you need the two-way kind; a calendar app with one-way import does not do that job.
Do genuinely free PMS plans exist?
Most “free” tiers in this market are trials or heavily limited plans designed to move you onto a subscription. What can be genuinely free is the calendar layer alone, because it can run on your device without any server costs. Disclosure: we make InnGrid, whose calendar is free forever on that exact logic — the paid part is narrow and optional: OTA calendar import, iCloud sync, multiple buildings, and calendar sharing.
When is a full PMS clearly worth the money?
When you sell the same units on three or more channels, want dynamic pricing, need a direct booking website, or run a team that lives in a shared inbox. At that scale the subscription replaces real hours of work every week — that is what the fee is for, and no free tool honestly substitutes for it.
