It's 11:41 pm. You're long asleep. A guest is checking in. With MINT, no problem.
MINT is the complete property management system for professional short-term rental operators with 20+ units. Self check-ins, door-code distribution, boarding pass, smart guest messaging, invoicing and many more processes run automatically, perfectly in sync. So your operation grows — not your to-do list.
Built by operators, for operators. Tested every day on real guests and real door locks.
Everything your operation needs. One system.
Reservations, guest messaging, check-ins, invoicing, housekeeping and automation all work together in MINT — instead of across ten different programs.
- PMS
- Channel manager
- Guest messaging
- Boarding pass
- Direct bookings
- Self check-in
- Door control
- HousekeepingModule
- Invoicing
- Automation
- TasksModule
- Multi-property
Every area works together — because they were built together from day one.
You wanted to be a host. Not a message center.
"We're at the door, the code isn't working." — WhatsApp, while you're sitting on the couch.
Booking.com reports a new booking. Your calendar in Excel doesn't know yet.
A guest needs the invoice. Including tourist tax. Right now.
Cleaning asks which apartment first. Six guests are arriving today.
You'd actually planned to have today off.
You don't have a PMS problem.
You have a complexity problem.
Your tool was the right call. For the start.
Most operators who come to us already run a booking tool — calendar and channels work fine. Yet the work keeps growing with every unit, because the actual operation happens outside the tool. And eventually you're facing a choice that isn't really one:
The entry-level tool manages the booking. Not the operation.
Calendar, channels, pricing — that's its job, and it does it well. But door codes live in the lock app, guest questions in WhatsApp, invoices in templates, cleaning in Excel. Every unit grows the mess around it — and you're the one holding that mess together.
The big enterprise suite. Built for corporations — not for you.
A months-long sales and setup process, support by ticket, in English. Powerful, sure — but for 50 to 200 units, an apparatus that costs you months before it eases a single night.
MINT — built for exactly this growth stage.
Self check-in, boarding pass, guest messaging and invoicing are built in, not bolted on — MINT fully replaces your current tool, no second system running alongside it. Guided migration, no minimum term, your price in 15 minutes — support from operators. The step after the entry-level tool — without the enterprise pain.
Here's how simple switching is ↓A booking comes in. Everything else happens on its own.
No marketing copy — this is the complete flow. MINT runs every step, in the right order, and only speaks up when a human genuinely has to step in.
Guest books
Airbnb, Booking.com, Expedia or direct — MINT creates the reservation and blocks the calendar everywhere.
Door code is generated automatically
Via Nuki or UniFi Access, scoped exactly to the booking dates — or as a code for your key safe. No handover, no meeting.
The guest gets everything — in advance
Directions, parking, Wi-Fi and door code land automatically in the digital boarding pass — EN/DE, no app, no login.
The guest books add-ons — on their own
Late check-out or early check-in right in the boarding pass, payment included. Extra margin without a single phone call.
Cleaning gets scheduled Add-on module
At check-out, the job goes out via the Ops module — with a time window and the property address.
Invoice goes out
GoBD-compliant including tourist tax, filed cleanly. In the morning, all you see is: done.
From operators. For operators.
"We didn't build MINT because the market still needed a PMS. We built it because our own operation was hanging off too many tools, processes and manual tasks."
We run our own apartments in North Rhine-Westphalia. Not as a test environment or a showroom — every day, with real guests, real arrivals, real questions and real door locks.
MINT didn't come out of a business plan. It came out of our own everyday work.
We didn't want another piece of software that solves only part of the problem. We wanted a system that makes our own operation simpler — and gives us back time for what matters: our guests and our business.
Before we built MINT, our digital agency built software for DAX-listed and industrial companies. Today we combine both: the experience of professional software engineering and the everyday reality of running a rental operation.
Every feature has to make our own operation better first. Only then does it become part of MINT.
What proves itself in daily use makes it into the product. What only looks good on paper doesn't. That's why you won't find features in MINT built just for sales decks — only functions we use ourselves, every day.
GDPR-compliant processes. GoBD-compliant invoicing. WhatsApp instead of SMS-only. Honest answers instead of sales talk. And a product that keeps growing alongside our own operation.
Because we don't build MINT for operators.
We build MINT as operators.
A link that thinks ahead — and keeps the guest with you.
With MINT, the guest experience is built in, not bolted on: every guest gets a real boarding pass. Door code, Wi-Fi, directions, house info, check-in times and bookable extras — one link per guest, no app download, no login. Upsells like late check-out run right through the link, payment included.
And after checkout, the link stays your direct line to the guest: the next booking runs straight through you — no platform fee. A platform guest becomes a direct guest.
Before. After. The difference is your evening off.
Everything here runs live today and is proven in our own operation. What's still coming is listed honestly further down, in the automation levels.
Self check-in Live
Coordinating key handovers, answering the phone at 11 pm, "we're at the door".
The guest arrives on their own. Door code automatic — via Nuki, UniFi Access or key safe, valid exactly for the booking.
Boarding pass Live
17 messages per arrival: directions, parking, Wi-Fi, code, check-out time …
Most questions never even come up — it's all in the boarding pass. One link, EN/DE, no app.
Invoicing Live
You have to remember. Every single one. Including tourist tax.
Invoices are generated automatically — GoBD-compliant, tourist tax included, filed cleanly. e-invoicing & DATEV: in progress
Messaging Live
Five apps, messages everywhere, the same ten questions every day.
One inbox for WhatsApp, email and booking messages. Saved replies with one click. AI replies: in progress
Direct bookings Live
Every returning guest books through the platform again — with fees of up to 20 %.
The boarding pass keeps the guest with you. The next booking runs straight through you — no platform commission.
Calendar & pricing Live
Maintaining availability per channel, adjusting seasonal prices by hand.
One multi-property calendar for every channel. Pricing updates automatically via the PriceLabs integration — own PriceLabs account required.
How much you hand off is your call — level by level.
We believe hosts should be hosts. Not process managers. Our goal isn't for you to click faster — it's for you to click less. Not for you to use MINT all day — but for you to eventually forget it's even there. Because everything just works.
MINT grows with you. Levels 1 and 2 run live today, levels 3 to 5 we build step by step — honest progress instead of promised dates.
Set up & connect
liveAdd your units, connect channels and locks — door codes, boarding pass and invoicing run without you from the first night.
Saved replies at the push of a button
liveFor the same recurring questions: one click instead of retyping every time — fast, without turning impersonal.
AI-assisted replies
in progressThe AI drafts the answer from your property data — first with your approval, then automatically on request. Edge cases always go to a human.
AI + virtual assistants
expansion stageTrained assistants take over messaging and edge cases — fully managed through MINT. You see everything in the system without picking up the phone yourself.
Autopilot
the goalNear-complete hand-off of your business processes — "service as a service". Your operation runs, you keep control and the numbers, but the system takes over the daily work.
Switch without risk. Really.
The PMS switch is the reason you're still stuck with a tool that's long since started to annoy you. So we turned switching into a product: guided, checked, with a go-live date that you set — not us.
Migration check
15 minutes. Afterward you know in writing what carries over automatically — and what doesn't. You decide whether to move forward.
Setup
We import your data, connect channels and locks, and set up your automations — each one tested with a trial booking before it goes live.
The go-live date
A clean, jointly planned switch — per property, with a reconciliation report for every single booking. Block first, then switch over. After that, MINT runs.
Our five guarantees
- ✓No lost booking. We reconcile every single one before and after the move — you get the report.
- ✓Double-booking protection. Your calendar is never unprotected: block first, then switch over, per property.
- ✓Personally guided migration. Data import, setup, reconciliation report and team training — our own Customer Success team handles it together with you.
- ✓Your data belongs to you. Complete data package in open formats — even if you leave again.
- ✓Honesty before you sign. Anything that doesn't carry over automatically is in your migration check beforehand.
What does NOT carry over automatically — with any provider
- Automated messages & rules are rebuilt from scratch. We set them up with you and test each one with a trial booking.
- Platform connections are re-linked — Airbnb, Booking.com and every other channel (listings & reviews stay fully intact!). On Airbnb this also activates Instant Book — that applies with any provider, we just tell you beforehand.
- Old invoices stay in the previous system — you get them handed over as an archive package.
What MINT gives you back every month — in hours and in euros.
Quick math — per guest, without MINT:
- Organizing a door code or key handover — and staying reachable in case something goes wrong
- Looking up and sending directions, parking, Wi-Fi and check-in info
- Answering the same questions — for the tenth time, weekends included
- Writing the invoice, looking up the tourist tax, filing it
With MINT this happens automatically — for every arrival, every night, without you noticing.
This is your savings — not the price of MINT. What MINT costs for your operation, you'll get in the free migration check.
Assumption: 4 arrivals per unit per month × roughly 25 minutes per arrival — the 17 messages at ~1 minute each (see above) plus organizing the door code, looking up info, and the invoice and tourist tax. Valued at your hourly rate, all amounts net. The 80 % that MINT takes off this is an experience-based figure from our own operation, not a guarantee. Your numbers may differ — the order of magnitude won't.
- Multi-property calendar — every unit at a glance
- Channel manager: Airbnb, Booking.com & Expedia
- Boarding pass for every guest — door code, Wi-Fi, directions, extras
- Unified inbox: WhatsApp, email & SMS in one place
- Self check-in: door codes via Nuki, UniFi Access & key safe
- Invoicing incl. tourist tax — GoBD-compliant, built for the German market
- Dynamic pricing via PriceLabs — integration included, own PriceLabs account required
Add-on modules — only if you use them
The base plan runs at no extra cost. Want more? Add it deliberately — transparent, cancel monthly.
Direct booking with payment
Direct bookings with payment handled through MINT — instead of a platform commission, only a small fee applies to the revenue generated this way. If you don't use it, you pay nothing.
Tasks, checklists & cleaning
The Ops module schedules cleaning and team tasks directly from MINT. A separate tool with its own monthly fee — add it on if you need it.
AI-assisted replies
The AI drafts replies from your property data — first with your approval, then automatically on request. Coming step by step as its own module.
Personally guided migration: backup, data import, reconciliation report, setup and team training — our own Customer Success team handles it together with you, through to the go-live date. After that, MINT runs on its own: software, not a service provider in your daily operation.
What MINT costs depends only on your unit count. You get the number in 15 minutes — binding, no negotiation, cancel monthly.
Get your free migration checkThe questions switchers actually ask us.
What does MINT cost — no fine print?
From €28 net per unit and month on monthly billing, with the per-unit price dropping automatically past a certain operation size — no negotiation. Cancel monthly. Our own Customer Success team personally guides you through setup — you get the exact number for both the software and setup in the 15-minute migration check: binding, the same for everyone.
How does the switch actually work?
Three steps: first the free migration check, then setup — personally guided by our Customer Success team, with data import and test bookings —, and finally a go-live date you plan together with us, per property — block first, then switch over. Anything that doesn't carry over automatically is spelled out in writing beforehand, in your migration check.
Switching feels too risky — everything depends on the PMS.
That's exactly why nobody starts with the switch itself — they start with the free migration check: 15 minutes, and afterward you know in writing what carries over automatically and what doesn't. Next we show you MINT live in a demo — honestly, including what the software can't do yet. Only once you're convinced do we move forward: we set everything up together with you, test every automation with a trial booking, and go live only when you say you're ready. You set the go-live date. As extra assurance, you get a reconciliation report for every booking and your complete data package in open formats.
You can't automate guest communication.
The personal moments, no — and they shouldn't be. But booking confirmations, check-in details and the same ten questions are repetition, not hospitality. That's exactly what MINT takes over (today via saved replies, next AI-assisted), so you have time for the cases that actually need you.
What does the boarding pass have to do with my margin?
A lot. Airbnb and Booking.com charge a fee per booking. The boarding pass puts all the guest's information in one place — and after checkout it stays your direct line to them: the next booking runs straight through you, with no platform commission. A platform guest becomes a direct guest.
What happens to my Airbnb and Booking listings and reviews?
They stay fully intact — ranking, reviews, photos, everything. Only the technical connection is re-linked. Two honest notes: on Airbnb that means a planned go-live date (only one channel manager can be connected at a time), and Airbnb turns on Instant Book in the process. Both apply with any provider — we just tell you in advance.
How stable is MINT as a still-young company?
Before we built MINT, our digital agency built software for DAX-listed and industrial companies — professional software engineering isn't new territory for us. And MINT runs in our own operation first, every night, on real guests and real door locks, before any feature becomes part of the product. On top of that, switching carries no risk for you: our own Customer Success team personally guides you through the migration, and you can take your data package with you at any time.
Is there a minimum contract term?
No. MINT is cancellable monthly — no annual contract, no minimum term, no notice period beyond the current month. When you leave, it really ends: you take your complete data package with you in open formats. We want to keep you with the product, not the contract. Of course, you're welcome to agree a 1- or 2-year contract with us instead, if you prefer to plan ahead.
What about data protection and server location?
MINT is built in Germany and GDPR-compliant. Your data and your guests' data sit on servers in the EU — no detour through US clouds. A data processing agreement (DPA) is included as standard. We clarify the details transparently before you sign.
Which systems and devices does MINT work with?
Channels, smart locks, payments and more are connected — here are the main ones:
Channels are marked in amber, hardware & services in mint. We review other integrations case by case — just ask us.
Besides Airbnb and Booking, can I connect other platforms too?
Yes — additional platforms are possible. Airbnb, Booking.com and Expedia are directly supported; anything beyond that we review case by case and coordinate individually with you.
What if I'm coming from a system other than Smoobu or Guesty?
For Smoobu and Guesty, the path is already built, and the import runs largely automatically. Coming from another system, our Customer Success team handles the move together with you as part of setup: we pull your data out with you and rebuild it in MINT with guidance. What carries over automatically and what needs to be recreated is spelled out in writing beforehand, in your migration check.
I have fewer than 50 units — is MINT still worth it?
MINT is built for operations from around 20 units upward. If you're below that and growing, get in touch anyway — in the free migration check we'll tell you honestly whether it already pays off for you.
The guest arrived at 11:48 pm!?
You slept right through it.
That's exactly how our own operation runs — every day and every night. MINT was built for exactly this, and proves itself daily on real guests, real arrivals, real questions and real door locks.
Whether you want to grow or simply work with less pressure: your operation shouldn't depend on your constant attention. Let's find out in 15 minutes whether MINT makes your day-to-day easier too. Then you decide.
