Your contractor's invoice arrives as code. You're required to keep it for years.
Most landlords don't realize they already have to receive, read and store electronic invoices. Zetaro does it automatically — sorted by property, kept for as long as the law requires.
One home for everything around your property
Six parts already working end to end — try them out below.
Handwerk & Instandhaltung
A guided, multiple-choice wizard turns "something's broken" into a ready-to-send request — across 17 categories and nearly 100 specific areas, from a leaking tap to a new roof. Each contractor gets their own link — no account needed: propose a date, ask questions, upload the invoice. It lands straight on the case.
Immobilien
Buying, selling, renting out or searching — answer a few questions and get a proper request letter, or fill in the full property details and publish straight to Kleinanzeigen, ImmoScout24 or Immowelt.
Objekt-Akte
Documents, cases with warranty deadlines, tenancies from move-in to move-out and a tax overview with income and expenses — across all your properties too, filed automatically and audit-proof.
Tenancies
Rent account with bank-statement import, dunning, service charge statements with CO2 split, handover protocol and deposit — from move-in to move-out in one file.
Cancellations
Rent, gym membership, insurance, subscriptions — a guided flow drafts a ready-to-send cancellation letter and checks whether your chosen date is realistic.
Tenant channel
A deliberately minimal, free channel for your tenants — report an issue, track its status, nothing else. Optionally with a photo of the problem. No documents, no invoices, no other tenant data.
From property details to a live listing
Fill in square meters, rooms, condition and price once — Zetaro turns it into a proper listing text and opens it, ready to paste, on the platform you choose.
Die Fakten in 30 Sekunden
müssen alle Unternehmen — auch private Vermieter — E-Rechnungen empfangen können.
wird der Versand stufenweise Pflicht — auch Ihre Handwerker stellen dann elektronisch in Rechnung.
müssen Rechnungen je nach Belegart unverändert, lesbar und revisionssicher aufbewahrt werden.
Echte E-Rechnungen (XRechnung, ZUGFeRD) sind strukturierte Daten — ohne passende Software nicht lesbar.
A rule most landlords haven't heard of yet
No legal jargon — just what actually matters for you.
Was genau im Gesetz steht
You're already required to receive them
Anyone renting out property counts as a business for VAT purposes and must be able to receive electronic invoices — a plain inbox technically qualifies, but that's where the problem starts.
They're not readable on their own
A real e-invoice is a structured file, not a PDF. Without the right software, you can't actually open or check what it says.
You have to keep them for years
Invoices must be stored unchanged, readable and audit-proof — depending on the document type, for six to eight years. A folder on your laptop won't hold up if it's ever checked.
The obligation is rolling out in waves
Since 2025 you must be able to receive e-invoices. From 2027, larger businesses must also send them, and by 2028 it applies to virtually all B2B transactions — including contractors who will increasingly bill you electronically.
Every gap counts during an audit
Missing or improper archiving can trigger follow-up questions, estimates, or in the worst case back-payments with interest during a tax audit. A clean archive is what protects you.
Three steps, zero disruption
Keep the contractor you already trust. Zetaro only takes care of the paperwork.
Set up your inbox
Add your Zetaro address with your contractor, or simply forward invoices — done in two minutes.
Invoices arrive automatically
Zetaro recognizes structured invoice formats, turns them into something readable, and files them under the right property.
The record is complete
Quote, confirmation, delivery note, invoice — stored for six to eight years, searchable any time.
More than an inbox
Receiving is the requirement. The rest makes renting easier.
Smart invoice inbox
Recognizes structured invoice formats automatically and makes them readable without extra software.
Case tracking & warranty radar
Every request becomes a trackable case, linked automatically to its documents — with automatic warranty-deadline reminders.
Request assistant
A few clicks — bathroom, toilet, seat broken — and Zetaro drafts the request to your contractor.
Tax overview
Income and expenses per property and year, plus the groundwork for Anlage V — ready for your tax advisor, no spreadsheets required.
Real-estate requests
Buying, selling, renting out or searching — a guided flow drafts the right letter for each situation.
Listing creation & publishing
Enter the property details once, get a polished listing text, and open it ready to paste on the platform of your choice.
Set up in under a minute
Create your account, add your first property and forward an invoice — that's the whole setup. Free to start, no payment details required.
Free tier with one property, no time limit. Upgrade whenever you need more — or never.

Aus „irgendwas ist kaputt" wird eine Anfrage, die ein Handwerker beantworten kann
Die meisten Anfragen scheitern nicht am Handwerker, sondern am Text: zu wenig Angaben, kein Zugang, keine Frist. Dann kommt eine Rückfrage statt eines Termins. Zetaro stellt stattdessen die Fragen, die ein Betrieb ohnehin stellen würde — Sie klicken sich durch, statt vor einem leeren Feld zu sitzen.
Anfrage Sanitär: Wohnung Beispielstraße 3 (V-0007) Sehr geehrte Damen und Herren, für eine von mir vermietete Immobilie bitte ich Sie um ein Angebot im Gewerk Sanitär. Unser Zeichen: V-0007 — bitte bei Rückfragen und auf der Rechnung angeben. WAS GEMACHT WERDEN SOLL Wasserhahn in der Küche tropft seit zwei Tagen, Dichtung vermutlich defekt. RAHMEN Zeitraum: in den nächsten zwei Wochen Zugang: Mieterin ist werktags ab 16 Uhr da Ihre Rechnung stellen Sie bitte als elektronische Rechnung (XRechnung oder ZUGFeRD) aus.
Every property, its own file
Here's what your property files would look like — quotes, confirmations, delivery notes and invoices, filed automatically.
This interactive demo uses sample data and is currently available in German only. More languages are on the way.
Die Rechnung kommt als Datei — und muss acht Jahre unverändert bleiben
Seit 2025 müssen alle Unternehmer elektronische Rechnungen empfangen können, auch private Vermieter. Eine XRechnung ist aber kein Bild, sondern eine Datei voller Daten: ohne passendes Programm sieht man nichts, und ausdrucken hilft nicht — aufbewahrt werden muss das Original. Zetaro nimmt sie entgegen, macht sie lesbar und legt sie so ab, dass sich später beweisen lässt, dass niemand sie angefasst hat.
Rechnung · Sanitär Huber e. K. · RE-2026-3312 Objekt Wohnung Beispielstraße 3 Vorgang V-0007 Betrag 214,20 € brutto (180,00 € netto + 19 % USt) Leistung 12.–14.07.2026 Eingang 27.07.2026, 18:02 — per E-Rechnung an Ihre Zetaro-Adresse Prüfsumme SHA-256 9f2ac1…e77b — seit der Ablage unverändert Aufbewahrung bis 31.12.2034 (§ 147 AO)
Mängel werden gemeldet — nur leider nirgends festgehalten
Der Anruf kommt abends, die Nachricht am Wochenende, der Hinweis im Treppenhaus. Ein halbes Jahr später weiß niemand mehr, wann der Schaden zuerst gemeldet wurde — und genau darauf kommt es an, wenn es um Mietminderung oder Gewährleistung geht. Der Mieterkanal ist ein Link, den Sie weitergeben. Ihre Mieter brauchen keine App und kein Konto, und trotzdem steht am Ende alles mit Datum in der Akte.
Neues Anliegen · Wohnung Beispielstraße 3 Von M. Keller — Kontaktangabe freiwillig Kategorie Wasser / Sanitär Gemeldet 02.08.2026, 09:30 Uhr Anliegen Wasserhahn in der Küche tropft seit gestern.

Einmal hinterlegt — und in jedem Schreiben richtig
Name, Anschrift und Steuernummer stehen unter jedem Kündigungsschreiben, in jeder Handwerker-Anfrage und in der Verfahrensdokumentation. Sie einmal zu hinterlegen spart nicht nur Tipparbeit — es verhindert die Sorte Fehler, die niemand bemerkt, bis ein Schreiben unwirksam ist. Und was Sie hinterlegen, bleibt Ihres: jederzeit vollständig herunterladbar, jederzeit löschbar.

Less than a single specialist tool — with more included
Comparable tools often charge more for a single piece of what Zetaro does end to end.
What comparable systems currently cost
E-invoice archiving alone
Standalone GoBD-compliant e-invoice archiving tools typically start around €7–10 per month — and that's before any property or request management.
Property management software
Tools for small private landlords generally run €5–12 per month, without dedicated e-invoice compliance or a request assistant.
Professional systems
Full-featured platforms for larger portfolios or property managers start around €49 per month and up.
Based on published pricing from German providers, as of mid-2026.

Pricing questions
Is VAT included in the price?
Yes. The prices are final prices and nothing is added: as a small business under § 19 UStG, Zetaro currently does not charge VAT.
Is there a minimum contract term?
No. Invoices, Plus and Pro run monthly and can be cancelled any time to the end of the current billing month — with "Cancel contracts here" at the bottom of every page (no sign-in needed), in the customer portal or by email.
What happens to my data if I cancel?
Nothing is lost. Your account continues on the free plan; all documents and details stay, including properties above the limit. Features of the paid plan are locked until you upgrade again. You can export everything or delete your account yourself at any time.
Before you sign up
Do I need to issue e-invoices myself as a landlord?
Usually not — for private residential renting, the lease itself counts as the invoice. You still need to receive and store incoming e-invoices, for example from contractors.
Will I lose my current contractor relationship?
No. Zetaro doesn't replace your contractor — it organizes the communication and paperwork with the one you already work with.
When does Zetaro launch?
We're building the first version now. Signing up gets you early access and locks in the launch price.
Is my data secure and GDPR-compliant?
Yes. Database and documents are stored encrypted in a data centre in Frankfurt am Main, every connection is encrypted with TLS, and you can protect your account with two-factor sign-in. For your tenants’ data you conclude a data processing agreement with Zetaro. What the measures do — and what they don’t, such as no end-to-end encryption — is stated openly in the privacy policy and the agreement.
Is Zetaro for private landlords or professional property managers too?
Primarily for private landlords with a handful of properties. For larger portfolios or professional property management, get in touch directly — we're expanding the platform step by step.
Can I cancel anytime?
Yes. Invoices, Plus and Pro can be cancelled monthly with no minimum term — with "Cancel contracts here" at the bottom of every page, in the customer portal or by email. You end the free plan by deleting your account.
Does Zetaro replace a tax advisor or real-estate agent?
No. Zetaro organizes communication and paperwork, but doesn't replace legal, tax, or real-estate advice.
Does publishing to Kleinanzeigen, ImmoScout24 & co. really happen automatically?
Right now, Zetaro copies the finished listing text and opens the right platform for you. Fully automatic transfer via an official interface is planned as a next step, once we have partnerships with the platforms.
What languages is Zetaro available in?
This page is available in German, English, Spanish, French, Turkish and Russian. The app itself and the interactive demo are currently German-only; more languages are on the way.
Which countries is Zetaro built for?
We're starting in Germany, where e-invoicing rules are most concrete right now. Other European countries with similar rules are planned next.
Do my tenants have to pay to use the tenant channel?
No. The tenant channel is included in your subscription and free for your tenants to use — they can report issues and see the status, nothing more. They never see your documents, invoices, or other financial data.
