Description
Malta-based owners of rented property in Germany often want one tidy tool for contracts, rent and yearly accounts. WISO Vermieter 365 does that job, and TresBizz sells it as a licence for one user, valid for twelve months.
A word of caution first: every screen is in German, and the logic follows the German tax and banking system. The programme fits landlords with property in Germany, so please make sure that describes you before ordering.
Think of it as a digital filing cabinet for your lettings. Agreements, payments and cost statements live together, so you stop chasing paperwork across folders and inboxes.
Main capabilities
- Tenant and property records: one organised file per let
- Rent follow-up: check which payments arrived and which are overdue
- Cost settlements: draw up the annual service charge statement for tenants
- Templates: reuse prepared documents for letters and notices
- Licence size: one user, twelve months
Small portfolios benefit most. Information is typed in once and reused, which makes the annual settlement calmer and quicker.
A typical session: open the property, update the tenant, tick off the rent received, and prepare the yearly settlement when the time comes.
Licence details
There is one version on offer, spelled out below:
- Seats: 1 user
- Validity: 12 months
- Designed for: private landlords in Germany
- Interface language: German
It covers a single person. For colleagues or family members who also need access, put extra licences in the same basket.
Shopping with TresBizz
TresBizz works from Brussels, Belgium, and supplies software digitally to customers across Europe. Maltese buyers settle in euro using a card, Apple Pay, Google Pay or PayPal. You receive an official VAT invoice with every order, and EU companies can type in their VAT number at checkout. Everything we sell is a genuine licence.
Your key and download link are sent by email, normally within minutes and always within 24 hours. Help is available by email. Should a key refuse to activate, we send a replacement or give your money back. The licence is intended for activation in the European Union.
Technical needs
The product details name just two things:
- Windows 10 or 11 as the operating system
- An internet connection when you activate
Nothing else is specified, so a reasonably current Windows laptop or desktop with internet access is enough to plan around.
Delivery and set-up
After payment an email arrives with your key and the link to download the software. Save the installer, run it on Windows, then enter the key to switch the programme on.
Since the product follows German conditions, take a moment to confirm it suits your lettings. If anything is unclear, send us an email.
The programme helps you organise and prepare paperwork. It is not personal advice, so you remain responsible for what your documents contain.
