The problem

Your PMS is fine.
Your operations are not.

  • 50 apartments, 4 people. Yesterday you replied to the same WiFi question twelve times.
  • Three guests are still "Zahlung ausstehend" on Booking and nobody chased them.
  • Charlotte forgot tomorrow's cleanings. The board that should remind her lives in someone's head.
  • Your phone buzzed at 23:47 because a guest's check-in code stopped working.
  • This is not a software problem. This is an operations problem. fritz-comms is an operator.

What it does

Three jobs. One operator.
Always on.

Each panel below is a separate sub-system in production today, running on real guest traffic for the stayFritz portfolio.

01

Guest Communication

Every guest, every channel, 24/7 — with the actual reservation context. Not a canned FAQ bot.
  • Email · WhatsApp · Instagram DM · Airbnb · Booking inbox
  • Per-property AI personality, check-in code, parking, voice
  • Anti-hallucination verifier — no wrong check-in times, ever
  • Native DE · EN · IT · FR · ES · NL
  • Takes real actions: extra towels, babybeds, late checkout
02

Mission Control

Telegram or WhatsApp. Ask anything in plain German or English. Inline action buttons — no app switching.
  • "Welche Abreisen heute? Alle gezahlt?" → one tap
  • Assign payments, retry messages, accept worker assignments
  • Multi-user · owner, operator, ops group · role-filtered tools
  • 70+ tools across reservations, payments, messages, ops
  • Typing indicator while it thinks. No mystery latency.
03

Autonomous Operations

Four daily heartbeats + 15-minute always-on cycle. The back-office runs without you watching.
  • Auto-assigns Stripe + bank-transfer payments by reference
  • Auto-generates checkout invoices after 10:00
  • Scores housekeepers by familiarity, workload, skill match
  • Files waste-collection tasks 7 days ahead from 28 iCal feeds
  • Daily integrity sweep — detects + heals routing drift
Heartbeat report card

Four briefings a day. One always-on cycle every 15 minutes.

The heartbeat is the back-office working in the background. Below is a real noon update, redacted.

Why it's different

Not another inbox tool.
An actual operator.

We respect Smartbnb / Hospitable / Enso — they solved guest replies. fritz-comms solves the entire shift.

Pet fees, check-in, cancellation, payment terms, escalation thresholds — editable in plain English at /rules. Takes effect immediately.
AI escalates when uncertain.
Every conversation carries a handoff_reason. Every escalated thread pings your team by email + Telegram in seconds.
Tested on real guest traffic.
171 apartments, 18 months in production. Every weird OTA edge case has hit us first — so it doesn't hit you.
Founder note
"I'm a vacation rental operator. I built fritz-comms because no existing tool actually replied to guests the way I would — with the right information, the right tone, and the right follow-through. After 18 months running it on my own 50 properties, I'm opening it up to fellow operators. We onboard you personally. No sales calls with reps who've never managed an apartment."

FAQ

Questions we get every demo.

Does this replace my PMS?
No. fritz-comms sits ON TOP of your PMS (Smoobu, Hostaway, Guesty, Hostfully). It reads reservations, takes actions back. Your PMS stays the source of truth for inventory and pricing.
How long does onboarding take?
One week. Property-knowledge migration on day 1–2, rule customisation day 3, first guest reply going out by day 5. We do this with you — not a self-serve form.
What if the AI says something wrong?
A response verifier catches the common hallucinations (check-in times, online checkout, services that don't exist). For anything subjective, the AI escalates instead of guessing. You'll see a handoff_reason explaining why.
Can I see it before signing?
Yes. We'll screen-share our live production dashboard — anonymised — and show you yesterday's actual guest traffic. 20 minutes, no slides.
Where does the data live?
EU only. Hetzner Nürnberg. GDPR by default. Your guest data never leaves the EU and never crosses into another customer's workspace.
What about my existing inbox?
Email-forward your existing addresses into our worker. Old inboxes keep working in parallel until you switch the MX. No big-bang migration.
What does it cost beyond the subscription?
LLM API calls. Roughly €0.06–€0.12 per autonomously-handled guest reply, depending on length. We show you the live cost per conversation in the dashboard.
