For rental companies
Your fleet. Your prices. Your terms.
Rentrium is a marketplace for vehicle hire in Greece. You publish your own vehicles, you decide what they cost and what the rules are, and you choose whether your customers pay online, straight into your own payment account, or at your desk. The customer sees one total before they book.
Introductory offer
Your first month carries no commission
Register while this is open and the bookings you take through Rentrium carry no commission for a month. Your dashboard shows the date it ends, and our ordinary commission applies from then on. There is nothing to claim and no code to enter — registering is the whole of it.

Four things stand between you and your first booking
The portal keeps this list on your dashboard until all four are done. It is not a wizard: they can be done in any order, and nothing is lost if you stop halfway.
Confirm your email address
A link arrives in your inbox. Until you follow it your vehicles stay out of the search results — it is how we know the address on the account reaches you.
Start your subscription
Your vehicles are listed while your subscription is active. How your customers pay is a separate choice: at your desk from the start, or online once you connect a payment provider of your own.
Add a branch
Where the customer collects the vehicle, and the hours you are open. A name and a region are enough to begin.
Add a vehicle and a daily rate
Choose the make and model from the catalogue, say what a day costs, and pick the branch it lives at. A vehicle becomes bookable once it has both.
Most of the form is already filled in
Pick a make and a model and the specification comes with it — gearbox, fuel, seats, doors, luggage, air conditioning. Leave a box empty and it keeps following the catalogue, including any later correction. Your branch address is chosen from the Greek municipality and settlement registers instead of typed, with the municipality shown beside every name that occurs more than once.
If you have not photographed a vehicle yet, its listing shows the catalogue picture of that model and says that is what it is.
One rate all year, or a rate per season
Set what a day costs. If your August is not your November, give a range of dates its own daily rate — any day you do not cover keeps the vehicle's normal rate, so you only add the periods that differ. A rental that crosses two seasons pays each day at that day's rate.
Your rental terms, read before they book
Deposit, minimum driver age, fuel policy, how much notice you need, the shortest and longest rental you will take, what a late cancellation costs. You write them once and the customer reads them on the same page as the booking button, not at the desk.
Every booking keeps its own copy of the terms that were on screen when it was made, so a change you make afterwards cannot reach back into a booking somebody already holds.
The whole fleet on one calendar
Every vehicle a row, every day a column. Take a booking, change one, put a vehicle off the road for a week or for a single day — from the row it belongs to.
Two bookings can never land on the same vehicle at the same time. That is refused by the database rather than by the screen, so it holds however the booking arrived.
A customer at your counter goes on the same calendar
Write the booking at the desk and from that moment the vehicle stops being offered online for the booked period, so the two can never collide. Rentrium takes no commission on a booking you took yourself, nor on bookings your customers make on your branch page or through its QR code.
Every branch keeps its own hours
A vehicle lives at a branch, and it is offered only when that branch is open at both ends of the rental. Set your holidays and one-off closures per branch. A branch that never sets its own hours simply uses the usual ones.
Take the vehicle to them
Deliver within a radius you set around each branch, or to points you name, such as an airport or a port, each with its own fee. Set a minimum rental length, and free delivery from a number of rental days. The customer chooses delivery at checkout and the fee is included in the total they see before booking.
Your listing appears on every language version of this site
Somebody planning a holiday in German or in Russian reads this site in their own language and finds your vehicle inside it, at the same total price.
What you write about the vehicle stays in the language you wrote it in. We translate the site, not your words.
Reviews you can answer
Every review here comes from a booking with this rental company that was confirmed and never cancelled, written by the customer whose booking it was, from an account with a confirmed email address, after the rental period had ended.
Cancelled bookings (including ones the company reported as a no-show) and bookings still awaiting payment or the company’s confirmation cannot be reviewed.
Every review gets one public reply from you, underneath it, in your own words.
What you earned, and what it cost
Every booking on which commission has become owed, with its value and the commission on it, in euro. A refund is its own line rather than a quiet edit to an old one. Take the whole ledger away as a spreadsheet, and check each commission invoice against it line by line.
One commission invoice is issued to you for each month in which your bookings carried commission, after the month has closed.
Give the desk its own logins
Someone who runs a branch gets that branch and its opening hours. Someone on the counter gets rentals, desk bookings, handovers and the calendar. Whoever keeps your books gets the figures and nothing else. Nobody receives more than you hand them, and nobody can create another owner.
Three numbers, and the bookings behind them
Your dashboard counts three things: what you hand over today, what is due back today, and what is out on rental now — whichever day it is due back, not only today. Each number is the same question as the list behind it, so the rows you land on are the ones that were counted. If the company is yours, a second card counts the deposits nobody has settled and the damage claims still open.
The counts are read once, when the screen opens. There is no chart on it and nothing measured against last month — better a number you can check against the list it came from than a line you would have to trust.
What you will need, and what you cannot change later
Above is what Rentrium does. Here is what it does not — better to know now than halfway through signing up.
An email address you can open yourself
We email you a confirmation link. Until you follow it, your vehicles stay out of the search results. We cannot do it for you, and no button skips it.
A payment provider of your own, if you want online payments
Your customers pay at your desk unless you choose online payments. For those you need a merchant account with a card payment provider that Rentrium supports, and opening one is the provider’s process, on the provider’s timetable.
Greece only, for now
A branch has to be in one of the Greek regions, and registration asks for an ΑΦΜ. If you are based outside Greece, you cannot finish signing up yet.
Your ΑΦΜ is entered once
It is printed on your invoices and cannot be changed in the portal after you register. Check the digits before you send the form.
Start with one vehicle
Put a single vehicle up, watch a booking come through, and move the rest across once you have seen how it behaves.
