How to use RentOp

RentOp is found in the left menu under RentOp: Dashboard, Calendar, Bookings, Leases, Properties, Channels, Reviews, Reports and Settings. This guide follows the order in which an agency usually starts: add a property, price it, connect the channels, open the website, and then run the daily work.

1. Add a property

A property is a place you rent out: an apartment, a house, a villa, a room. Each property has its own page with the tabs Details, Photos & videos, Prices, Calendar, Airbnb & co, Bookings and Translations.

1. Open RentOp → Properties and click New property.
2. Give it a name (for example Sea View Apartment) and choose how it is Rented as: Holiday stays, Long-term lease or Holiday stays and long-term. Click Create and open.
3. On the Details tab fill in What guests see (the one-line summary and the description), Where it is (address and the Tourist registration number), The space (guests at most, bedrooms, beds, bathrooms, size, amenities) and the Rules of a stay (arrival and departure times, nights at least and at most, cancellation, who cleans). Click Save details.
4. Write the key code and wifi password in Arrival instructions. They are private: only a confirmed guest receives them, shortly before arrival.
5. On the Photos & videos tab drop your photos (JPG, PNG, WebP) and videos (MP4, WebM, MOV up to 300 MB). Drag them to change the order.
6. Pick the picture or video that opens the listing and click the star: Make this the featured photo or video.

The featured item is what visitors see first: on the search card and at the top of the property page. If it is a video, it plays there on a loop, without sound. Visitors who ask their device for less motion see the video's still frame instead.

2. Prices and seasons

Open the property's Prices tab. Under Normal price set what a night costs outside any season: the Price per night, the Friday and Saturday night price (empty = the normal price), the Guests included, Each extra guest, per night, the Cleaning fee, the Security deposit (shown to the guest, not charged online), a Discount for 7+ nights and a Discount for 28+ nights. Click Save prices.

Then add Seasons with New season: a name (for example Summer), the First night, the Last night and the price. Every night in that range takes the season price. Where two seasons overlap, the shorter one wins, so a short August season can sit inside a long Summer.

The Tourist tax is charged per adult per night. Set the amount for all properties in Settings → Taxes; a property with a different city rate gets its own amount on its Prices tab (empty = the amount in Settings). It is always its own line on the price and on the invoice, and VAT is never added on top of it.

Use Try a price at the bottom of the tab: pick dates and RentOp shows exactly what a guest would pay, line by line the same lines the website, the invoice and Marvin use.

With a 7-night stay the line Long-stay discount (10%) appears automatically, and with more guests than included the line 2 extra guest(s). Prices you change later never touch bookings already made: each stay keeps the price it was booked at.

3. Connect Airbnb, Booking.com and Vrbo

RentOp keeps one calendar per property. Every night that is taken a website booking, a booking your team made, a channel's booking, a night you closed is held once. Channels are connected with calendar addresses (iCal), in two directions.

1. Calendars we read. On the property's Airbnb & co tab click Add a channel calendar, choose the channel and paste the channel's export address (it starts with https:// and ends in .ics). Click Save and read now. Where to find it: Airbnb: Listing → Availability → Connect calendars → Export calendar. Booking.com: Extranet → Rates & availability → Sync calendars → Export calendar. Vrbo: Calendar → Import & export → Export calendar.
2. Calendars we send. Copy RentOp's address for that channel and paste it into the channel's “import calendar” setting. Each address leaves out the nights that came from that same channel.
3. From now on the channel calendars are read every few minutes: a night sold anywhere is closed everywhere. RentOp → Channels lists every calendar with its last read, its events and its clashes; Read now reads one at once.

Clashes. A calendar address only says “taken”, and a channel may sell a night a moment before it hears from RentOp. When an imported booking falls on nights that were already booked, RentOp does not drop either one: it flags a clash. You see it on the Dashboard, under Channels → Clashes (with What the channel says and the Nights in both), as a red outline on the calendar, and as a notification. Contact the guest of one of the two stays and move or cancel it.

4. Publish and the website

When the property is ready, set its status on the Details tab to On the website and save. Only properties “On the website” can be booked online. If A property needs its registration number to go on the website is switched on in Settings, RentOp refuses to publish a holiday property without its tourist registration number. See on the website opens the public page.

Your website lives at your-workspace/rentop. It opens with a search (where, dates, guests) and shows a card per property with its featured photo or video and the price for the chosen dates. Behind the search you can show a banner: in Settings → Website → Banner choose what goes Behind the search Nothing (plain page), A photo or A video upload it, write the Title on the banner and use Darken the banner so the white title stays readable on a bright picture. A live preview shows the result before you save.

A guest books in a few steps on a phone or a computer:

1. Search, open a property and see its gallery, description, amenities, house rules, reviews and the availability calendar. They pick their arrival and departure days; the price appears line by line.
2. Click Book these dates, fill in Your details, accept the terms and click Book and pay.
3. Pay with Stripe or Mollie (the methods that have their keys in Settings → Payment methods). The nights are held while the guest pays; a hold that is not paid in time is released for others.
4. The payment is recorded on the stay's invoice, the stay becomes Confirmed and the guest gets a confirmation by e-mail with a link to their own booking page.

The guest's booking page. Every booking has its own private page, linked from every message. There the guest can:

• Pay what is still open (the deposit or the rest of the stay) “Pay …” opens Stripe or Mollie again.
• Sign the agreement when the property asks for one: read it, type the full name, tick “I have read the agreement and I agree to it.”
• Fill in the guest list: name, nationality, date of birth and ID document of every person, as the law asks it saves time at the door.
• Cancel my booking: the page says first how much comes back under the property's cancellation policy.
• Leave a review after the stay. Reviews appear on the website after you read and publish them.

For a property let long-term, the website shows the monthly rent and an “Interested? Tell us.” form instead of a booking. The enquiry becomes a lead in your workspace. If you switch on the Marvin chat in Settings → Website, Marvin answers visitors' questions on the website and your team takes over when needed.

5. Calendar and daily work

RentOp → Dashboard (“Today at your rentals”) shows the arrivals and departures of today, who is staying now, the occupancy and revenue of this month, and what needs you: bookings waiting for payment, channel clashes, reviews to check, cleanings still to do, and properties without a registration number.

RentOp → Calendar is the screen the agency lives in: every property as a row, every night as a column, stays as bars. Use Earlier and Later to move in time. Striped bars are waiting for payment; a red outline is a clash with a channel. Click a stay to open it.

Bookings by phone or e-mail. Click New booking. In The stay choose the property, the arrival, the departure and the guests the price appears as you fill it in. In The guest pick an existing client or write the guest's name and e-mail (a new guest becomes a client). Use Price for the whole stay only when it differs from the price list, for example a channel's payout. Click Book and open: the nights are taken, the invoice is made and the confirmation is sent.

On the day. Open the stay and click Check in when the guest arrives. When they leave click Check out: a cleaning task is made for the property's cleaner (Who cleans on Details), due before the next arrival. Other buttons on a stay: Change dates or guests, Record a payment (cash on arrival, a bank transfer), Guest list, Did not come and Cancel the stay (the refund under the cancellation policy is proposed, and you can change it).

Close nights. For the owner's own stay or works, click an empty day on the calendar (or use Close nights), choose the range and a reason, and click Close these nights. Nights already booked are left alone. Open them again frees them. Closed nights are sent to every channel too.

6. Long-term leases

A lease is a tenant renting a property by the month. Its nights are taken in the same calendar as the holiday stays, so a property let “Holiday stays and long-term” can never be booked twice.

1. RentOp → Leases → New lease: the property, the tenant (an existing client, or a new name and e-mail), Starts, Ends (empty = until notice is given), the Monthly rent, Monthly charges, the Deposit, Rent due on day and Notice (days). Click Save as draft. A draft blocks and invoices nothing yet.
2. Check the terms and click Activate: the calendar is blocked, the first rent invoice is made it repeats every month by itself and the tenant is e-mailed with a link to the tenant's page.
3. Rent invoices appear on the lease under Rent invoices. A running lease is locked: only notes and the deposit can change.
4. To stop, click End the lease: the nights after the end date become free and no more rent is invoiced.

A lease without an end date keeps the calendar blocked a number of months ahead, rolled forward every day (Settings → Channels → Open-ended leases block).

7. Messages and agreements

RentOp writes to guests by itself, at the right moment, in the guest's language once per booking and kind of message:

• Booking confirmation when the stay is confirmed, with the link to the guest's booking page.
• Balance reminder when a deposit was paid, before the rest is due.
• Arrival instructions a few days before arrival: the address, the arrival time and your private arrival notes (key code, wifi).
• Review request a few days after departure.
• Cancellation when a stay is cancelled, with the refund.
• Lease welcome when a lease is activated.

The texts are edited per language in Settings → Email templates → RentOp. With the WhatsApp Coexistence App, guests who accepted WhatsApp also get the messages there. Every message sent shows under Messages on the stay, where Send a message sends one again.

Rental agreements. Tick Guests sign a rental agreement on a property's Details tab. In Settings → Agreements choose how it is Signed with: On the guest's booking page (name + tick), or NIZU Sign, which e-mails a PDF to sign with a full audit trail. The texts of the Short-stay agreement and the Lease agreement take placeholders such as {GUEST_NAME}, {PROPERTY_TITLE} and {CHECKIN_DATE}. The stay shows whether the agreement is signed, by whom and when.

8. Reports

RentOp → Reports has three tabs, each for one month:

• Occupancy & revenue per property: the stays that arrive in the month, the nights taken (bookings, leases and channels), the occupancy, the revenue and the average night.
• Tourist tax the guest-nights taxed and the tourist tax collected on the stays that arrived in the month: what you declare to the city.
• Guest register everybody who stayed, with the details the police registration asks for. Red dashes are missing details. Click Download CSV and upload or copy it into your country's portal (for example SES.HOSPEDAJES in Spain, Alloggiati Web in Italy, SIBA in Portugal).

9. Settings

RentOp → Settings has one subject per tab. Each tab saves only what it shows, with Save changes.

• General your Agency name (shown on the website and in e-mails), the currency of your prices, whether The website is open to visitors (off = visitors see “page not found”), More website languages, and the EU rule A property needs its registration number to go on the website.
• Website the Banner behind the search (nothing, a photo or a video, its title and how dark it is), the Welcome line and Brand colour, the contact e-mail and phone, the Marvin Live chat, and your legal pages: Terms, Privacy and Cookies (empty = a short standard text).
• Payments When guests pay: everything when booking, a deposit when booking and the rest before arrival, or nothing online; the deposit %, when the rest is due, how long unpaid bookings are held; Pay with Stripe and Mollie (each shows whether its keys are ready in Payment methods); and the VAT on stays and on rent.
• Taxes the tourist tax per adult per night, the age from which guests pay, and the most nights charged (some cities stop after a number of nights).
• Messages how many days before arrival the arrival instructions go out and how many days after departure the review request goes, a link to the e-mail texts, Also send on WhatsApp, and Make a cleaning task when a guest leaves.
• Agreements signed on the booking page or with NIZU Sign, and the texts of the short-stay and lease agreements.
• Channels how often channel calendars are read, and how many months ahead an open-ended lease blocks the calendar.
• Lists the Property types (apartment, villa, room…) used to filter the website, and the Amenities (Wi-Fi, pool, parking…) ticked on each property.

The Website tab shows a live preview of the banner. A photo should be wide and sharp (at least 2000 px across); a video is best 10–30 seconds, MP4 or WebM, without sound. Uploads go in small pieces, so even a large video uploads without a server limit getting in the way.

10. Marvin and AI

Marvin, the NIZU AI assistant, knows your stays and your calendar. Ask it in plain words, in the workspace or on Telegram:

• “Who arrives tomorrow?” the arrivals with guest, property and time.
• “Who leaves today?” and “Who is staying now?”
• “Is Villa Sol free 3–10 August, and for how much?” the availability and the price, line by line, from the same price list as the website.

Switch on Show the Marvin chat on the website in Settings → Website and Marvin answers visitors on your booking website too.

AI assistants (MCP). Through Agents, an AI assistant connected to your workspace (for example Claude) can use RentOp's tools: read rentop.properties, rentop.availability, rentop.quote, rentop.bookings, rentop.booking, rentop.arrivals and rentop.leases, run the report report.rentop, and with the right permission rentop.create_booking, rentop.cancel_booking and rentop.block_nights. They use the same calendar and price engine as the website, so an assistant can never double-book. In AI Reports, stays, leases and occupied nights are part of “All business data”.
